Re: [beagleboard] Video device not found error.

[jonnymo]

Things that would help to understand the issue are:

1. The output of the version.sh script:
  Ex:
sudo  /opt/scripts/tools/version.sh

2. Provide the Make/Model of USB camera used

3. What application is used when seeing the error?

4. Does the camera show in the 'dmesg' output and/or /var/log/syslog?

5. What troubleshooting steps have you taken thus far?


I think this would be a start in helping to understand your issue.

Cheers,

Jon

Re: [beagleboard] How to copy BeagleBoard image to a windows PC

[jonnymo]

One option is to use something like DiskInternals:
https://www.diskinternals.com/linux-reader/mount-linux-drive-on-windows/

I have never tried this myself though.

The other option is to use either VirtualBox or VMware Workstation Player
to create a Debian or Ubuntu VM on your Windows system and use that to read
the image from the eMMC.
Ex:
https://elinux.org/BeagleBone_Black_Extracting_eMMC_contents


I would suspect  there is a Docker example of this somewhere.

Cheers,

Jon

 The only way that I know is with :

 but you talk about mmap ? How did you use it with this
 /sys/class/gpio/gpio%d/value ?

 Thx you,

Re: [beagleboard] Re: Network setup taken over by something

[jonnymo]

Although a bit off track from the original subject, you may what to look at
some sort of lint tool to check you code for syntax errors.  If you use an
editor such as Eclipse or Atom, this may do this for you already.
https://en.wikipedia.org/wiki/Lint_(software)

You could also look at the warning and error level settings and options to
increase the level of complaints when the code is compiled.

Re: [beagleboard] Is it possible to run TI-RTOS or any RTOS on beaglebone blue?

[jonnymo]

For Ti-RTOS, you might want to start here.
http://www.ti.com/tool/PROCESSOR-SDK-AM335X

This looks interesting:
http://huesmanbros.com/marc/2017/09/22/getting-ti-rtos-running-on-the-beaglebone-black/


There is a page for QNX on the Beagleboard site, but perhaps more specific
for the BB Black or EVM.  It could be possible to try it with the Blue, but
I am not sure how they compare though.
https://beagleboard.org/project/QNX+Neutrino+on+OMAP/
http://www.qnx.com/products/reference-design/index.html

There are JTAG pads on the back of the Blue so you would have to carefully
solder headers to it and then use a JTAG programmer to load it. Again, all
theory in my case since I have not attempted this with my dead Blue.

Re: [beagleboard] Is it possible to run TI-RTOS or any RTOS on beaglebone blue?

[jonnymo]

Segger is an industry standard and if TI  does not support it with CCS then
I would suggest another MCU vendor.
There is this though:
https://wiki.segger.com/TI_Code_Composer_Studio

Besides, CCS is just a TI version of Eclipse, so anything that can be done
in CCS can be done in Eclipse.  It may take some work to get the project
set-up, but it is possible.

Re: [beagleboard] Re: SGX - OPENGL - Buildroot

[jonnymo]

I've seen the "Unable to create surface" error when OpenGL can not attach
to a display.  Are you doing this remote or do you have some sort of
display attached to the board and running locally?Also, have you
checked the output of glxinfo or run glxgears to see if it can display the
gears demo?

Cheers,

Re: [beagleboard] Is it possible to run TI-RTOS or any RTOS on beaglebone blue?

[jonnymo]

You must be reading a different Release note then I am reading.
This seems to show more than just cortex-m support.
https://www.segger.com/products/debug-probes/j-link/models/model-overview/#supported-cores

 Segger does lists the J-Link EDU Mini with full J-Link support though.
There is also the $60 J-Link EDU which is basically the same as the Base
without all the extra software.

However, the mini was just tossed out as a suggestion.  Its up the
individual to do the proper research to see what works best for their
environment.

Cheers.

Re: [beagleboard] Is it possible to run TI-RTOS or any RTOS on beaglebone blue?

[jonnymo]

You asked, if I had experience with TI-RTOS and if I had experience
with TI-RTOS with other IDEs and I answered yes to those.  However,  I have
nothing to prove to you or anyone else for that matter that does not
provide me with a paycheck.  Believe what you want, I could not care less.

However, you don't need an IDE to use any programmer, be it a Segger or
other. But, then again you know all so I would expect you already have done
this.

Good luck.

Re: [beagleboard] RE: Trying to Understand Complicated Source w/ Classes from the ServoCape and Python3/ServoCape and the PCA9685

[jonnymo]

If you provide a link to the source of this that would help.

But, basically in your own Python code you would first import the class

Ex:
  * from source_file import Pca9685*

The you could create an instance of this like:

  * my_servo_control =  Pca9685(bus_num, addr_val)*

You could need to know the value of bus_num and addr_val to set these.

Then you could call the methods as such:
   *my_servo_control.read_reg(reg_val)*

 Again, you would need to know what the value of reg_val is to set the
'reg' parameter for the 'read_reg' method.

You still need to know where it is getting the '*write_i2c_block_data*' and
*'read_i2c_block_data*' methods from though.
Perhaps 'import smbus' is missing?
https://learn.sparkfun.com/tutorials/python-programming-tutorial-getting-started-with-the-raspberry-pi/experiment-4-i2c-temperature-sensor


A course in Python wouldn't hurt.

Jon

Re: [beagleboard] RE: Trying to Understand Complicated Source w/ Classes from the ServoCape and Python3/ServoCape and the PCA9685

[jonnymo]

When you call the methods in the Pca9685 you need to pass the appropriate
parameters.

 Ex:
 read_reg( self, reg )

  You need to pass a reg value to this.

*   reg_val = some_reg_val*

I can't see the rest of your code so I am not sure if it will work or not.

Search the web for Python3 tutorials.

[jonnymo]

My reference to  reg_val  was just a reference and an example. I have no
idea what you need for the value which is something you need to research.

I have no idea where you got the original code from, but you should start
there.

Re: [beagleboard] RE: Trying to Understand Complicated Source w/ Classes from the ServoCape and Python3/ServoCape and the PCA9685

[jonnymo]

Oh, the error you are seeing is that 'int' does not have a len.  What you
may try is to convert it to a string and then get the len:

Ex:
  int_len =  len(str(0)

or
Ex: For values greater than 0.
  int_len = int(math.log10(int_val)) + 1

But I am not sure why you are getting the length of 0.

I don't have a cape, so I can not help you there.

Cheers,

Jon

Re: [beagleboard] Re: accessing P9.13 on Beaglebone AI

[jonnymo]

There is an open issue for the BBAI in reference to adding AB10 GPIO
support but states being added with rev. A2 which I thought was the current
rev board:
This is also mentioned in the System Reference Manual:
https://github.com/beagleboard/beaglebone-ai/wiki/System-Reference-Manual

HW: P9.13 does not have a GPIO:
https://github.com/beagleboard/beaglebone-ai/issues/22

Perhaps it was not implemented yet?

Cheers,

Jon

 I'm testing it a couple ways:

 2) with libgpio

 Both return a value of 0, when I'd expect it to be 1 (I don't have
 anything wired to it). Any idea what I'm doing wrong?

Etcher works with Linux and Mac:

It's fine for uSD cards less than 64GB, otherwise you need to format the

Running tcpdump on my Ubuntu system, I can see where the incoming traffic

getting routed out.

On BB:

On Host:

It seems that something either on the Ubuntu side or in the network is
blocking the traffic.

Re: [beagleboard] Re: Can not connect via USB

[jonnymo]

I can ssh between the PC and the BB via 192.168.7.x and back without
issue.
However, no traffic is sent out passed the wireless connection.

Re: [beagleboard] Re: Can not connect via USB

[jonnymo]

Okay, I solved my issue by adding an iptable entry for the return from
wlan0 to eth1 (BB).

* sudo iptables -A FORWARD -i wlan0 -o eth1 -j ACCEPT*


Now pinging '8.8.8.8' from the BB works as expected.

*root@beaglebone:~# ping -I usb0 8.8.8.8*
*PING 8.8.8.8 (8.8.8.8) from 192.168.7.2 usb0: 56(84) bytes of data.*
*64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=1 ttl=103 time=17.9 ms*
*64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=2 ttl=103 time=15.8 ms*

Sorry, I can't get that site to connect to my BBAI so I can not check to

Perhaps someone else will chime in.

Re: [beagleboard] Re: Not able to test node.js first demo program. Run throws error

[jonnymo]

Perhaps when posting code it would be best to use the Highlight Code Syntax
in Google.  Not sure what formatting is used in the email but looks like
from a README.

For me, I just went to the site that is in the images that Jennifer
provided.  The code could be pulled from there.

However, I believe the issue is with the BeagleBoard site and not with the
Cloud9 IDE on the board but could be related.

Re: [beagleboard] Re: Not able to test node.js first demo program. Run throws error

[jonnymo]

I connected a BBBlack to my Ubuntu Box via USB and I still can not get the
BeagleBoard.org page to connect to it. I even tried it to a Windows 10
system and still no go.
I've updated the Cloud9 code so I am not sure what the issue is.

I looked at the Chromium debug output and this is what I see:

*  Uncaught SyntaxError: Unexpected token '<'*
*bonescript.js:16 GET http://192.168.7.2/bonescript.js
<http://192.168.7.2/bonescript.js> net::ERR_ABORTED 404 (Not Found)*

However, my BBBlack gets connected at the following link, which looks like
a mirror of the beagleboard.org.
http://va3wdg.gw.ircddb.net/bone101/Support/BoneScript/

I can run the scripts from the site but I don't feel comfortable with the
funky URL but I at least know it is not the BBBlack nor my PC connection.

Perhaps there is an issue with the BeagleBoard.org Learn site?

Cheers,

Jon

Re: [beagleboard] micro - sd card

[jonnymo]

Are you referring to using a micro SD-card as a boot device?  I use a 32Gb
micro SD-card, and 64Gb on a BBAI..
If you use a 64Gb or greater card, then you'll need to format it as an
exFat drive.

Re: [beagleboard] Query on Beaglebone Black Rev C

[jonnymo]

You might need to disable the driver signing check on your Windows 8 system:
https://stackoverflow.com/questions/52065512/cannot-install-the-driver-of-beaglebone-on-the-windows-10

What image is installed on your BBB?

Also, I have been having an issue getting the BeagleBoard site to recognize
my BBB so I think there is an issue with the site.  I have filed an issue
for this on the BeagleBoard github but have not seen anything posted about
it.  You might want to check Developers Tools in your browser to see an
issue, but if the board is not connecting to your Windows system I do not
think the BeagleBoard site will pick it up.

Cheers,

Jon

Re: [beagleboard] Re: WiFi connectivity and possible external power supplies for BBAI

[jonnymo]

I suspect your resolv.conf got set back to the default with no nameservers
listed when the USB ethernet port went offline.

How do you have your wlan0 configured?
If you used connman, you can add the following to your connman settings:
 Ex:

*   IPv4.gateway=192.168.2.1   Nameservers=8.8.8.8;8.8.4.4;4.4.4.4;*

Typing 'route' should show your which network device the traffic is going
down.

Also, you can test this by using ping and specifying the ethernet port to
use:
Ex:
*ping -I wlan0 google.com *

Cheers,

Jon

Re: [beagleboard] Re: 192.168.7.2 is NOT opening or reachable

[jonnymo]

What image are you running on the BBB?

Also, are you seeing an "192.168.7.1" ip created on your Ubuntu PC?
You can check this using:
  * ifconfig -a*

You can check the 'dmesg' out on your PC to see if there are any errors
connecting to the BBB.

Re: [beagleboard] Re: WiFi connectivity and possible external power supplies for BBAI

[jonnymo]

The values I provided should set the /etc/resolv.conf for the wlan0
interface. The gateway you would want to set for your config.  I typically
run with a static ip on my wlan0 so I edit the connman settings manually
for my environment.  The other option is to do it manually or with some
script that detects the loss of your usb network connection and then set
resolv.conf accordingly.  This does take root access, so I find it best to
just add it to the connman settings.

You could check your /etc/resolv.conf on your BBAI after you experience the
USB sleep mode on your laptop to see if there are any settings still in
there. If not, then that might explain why you can not reach google.com
when the usb interface is offline.

Cheers,

Jon

Re: [beagleboard] Re: 192.168.7.2 is NOT opening or reachable

[jonnymo]

I believe Pankaj is using Ubuntu and not Windows.

Pankaj :
I would suggest checking that your Ubuntu system is creating a 192.168.7.1
ipaddress and is not having an issue connecting to the board via 'dmesg'.

Unplug and plug the BBB back in and then check the output of running the

 You should be able to ping 192.168.7.2 from the laptop, if you see
 192.168.7.1 on the laptop.
 Is this your personal laptop or a company laptop? companies tend to
 secure laptops such that ping and ssh aren't allowed (My personal
 experience)
 Would recommend getting an sdcard, again if this is a company laptop,
 it may not help.

Re: [beagleboard] Re: 192.168.7.2 is NOT opening or reachable

[jonnymo]

Yeah, I am only guessing that the power or cable is the issue, but it does
seem like it based on what I had seen in your dmesg output.

For upgrading the eMMC, I believe it would depend on how comfortable you
are running through the process.  It would be much easier via an SD card,
but I did find the following links related to this.
https://www.meetup.com/MKETechEngine/messages/boards/thread/37061872
https://e2e.ti.com/support/processors/f/791/t/404919?Writing-linux-image-to-MMC-without-SD-Card-on-BBB

Others might have better advice for you though.

Good luck.

Re: [beagleboard] Re: Beagleboard X15 Microsoft Visual Studio GUI example project

[jonnymo]

Actually, Visual Studio is a good platform for cross compiling especially
with the newer versions of VS.  There is a built in Linux feature that lets
you create Linux based projects and then you can just reference your ARM
based toolchain in the VS config. I use this with the RasPi but it should
be the same for the BB products.

Here are a couple of links that might help, although they are for BBB.
https://www.youtube.com/watch?v=af-1hDfoRcg
https://elinux.org/images/d/df/Using_VS_and_VS_Code_for_Embedded_Development.pdf


Using VisualGDB although I am not sure if this is needed any more.
https://visualgdb.com/tutorials/beaglebone/qt5/cross-compile/

You could toss in GTK or Qt or even OpenGL ES for graphics dev.

The other option is Qt Creator as Tarmo mentioned.

Eclipse is another good option.

Cheers,

Jon

What power supply with a switch are you using?  Did you add a switch inline

you are using?

Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

[jonnymo]

Are you plugging both USB cables directly to your PC or are you using a
Powered USB Hub?
I would suggest using a powered USB hub in this case if you were not using
one already or power the BBW via the barrel jack.

Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

[jonnymo]

That error you are seeing appears to come from your USB to Serial interface.

Re: [beagleboard] sudo problem

[jonnymo]

Looks like you posted this twice.

Did you make a change to your sudoers file? If not, then have you tried
changing to root via "sudo su -" ?

As far as the install issue, you need to run that with sudo when running as
the debian user:
Ex:
   *sudo apt-get install -y policykit-1-gnome*

You might want to check the host that is running MobaXterm.  Also, have a

Re: [beagleboard] Re: BBB network adapter connection failed, can't access board via ssh

[jonnymo]

Who does the output of 'ip a' show on your host Ubuntu computer with the BB
plugged in?
Also, when you plug the BB into the host, check the output of 'dmesg' to
see if there are any errors reported for the USB device or the usb ethernet
interface.

Re: [beagleboard] Re: Networking setup on robot with multiple debian SBCs

[jonnymo]

There does not seem to be any mention of a BBAI in the original post, but a
BBBlue is which does not have a wired Ethernet port.

However, it should be possible, that is if there are the necessary drivers,
to connect the RasPi and the BBBlue via USB network and then the Pi to
other devices via the wired ethernet port, but this does require some sort
of wired network in your config and/or a device acting as an AP, such as
the BBBlue,  if it is a mobile platform.

The other option I suppose would be to do something similar to ROS Serial
between the RasPi and the BBBlue to avoid any network stuff between the
two.

Re: [beagleboard] Re: libpruio (fast and easy D/A - I/O)

[jonnymo]

You could try adding the following to your Python 2 script to add Python 3
print  support.
"from __future__ import print_function"

However, there should be an effort to move from Python 2 to Python 3.

Re: [beagleboard] disable logging in beaglebone black

[jonnymo]

You could look at '/etc/rsyslog.conf' and disable any logging you do not
wish to keep track of.
You would have to either restart the board or restart the service for it to
take.

Ex:
  * sudo /etc/init.d/rsyslogd stop*
   *sudo /etc/init.d/rsyslogd start*

The other option would be to remove any .gz file under /var/log that you do
not want or create a script that purges these.

However, if you are getting an excessive amount of logging on something
particular like messages, then it might be best to find what that issue is
and see if it can be resolved.   Just a suggestion.


Cheers,

Jon

Re: [beagleboard] Re: Connecting Two BBBWs to One Another and Using One Script?

[jonnymo]

You could use something like MQTT where you run the Mosquitto MQTT server
on one of the BBBW and then publish and subscribe to shared topics between
the two.  I believe Node-RED might be another option.

Re: [beagleboard] IDE (eclipse) for Beaglebone on Windows

[jonnymo]

Yes, you can cross compile from Windows 10 to the Beaglebone but your best
option would be Eclipse since you can compile on Windows and then scp the
code over from Eclipse.  You can use Visual Studio but you would end up
having to build on the remote target and not on Windows.  However, with
Visual Studio you could use something like VisualGDB but will cost an extra
$99 US. You can download and use it for a month for free though.

Here are a couple of links that might help.

https://www.youtube.com/watch?v=af-1hDfoRcg
https://elinux.org/images/d/df/Using_VS_and_VS_Code_for_Embedded_Development.pdf


Using VisualGDB although I am not sure if this is needed any more.

Re: [beagleboard] IDE (eclipse) for Beaglebone on Windows

[jonnymo]

In Eclipse, just create a Run Configuration and set it to 'SSH' for your
target which is basically like SCP.  This should deploy the code and run it
on the remote target.

Re: [beagleboard] IDE (eclipse) for Beaglebone on Windows

[jonnymo]

Try downloading
the gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-linux-gnueabihf toolchain and
set the Cross Settings to reference this:
https://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabihf/

Just unpack the file and reference it in Exlipse.
Ex:
Prefix: arm-linux-gnueabihf-
Path: "Path to the toolchain"
Ex:

PATH: 
H:\Development\BeagleBoard\Toolchain\gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-linux-gnueabihf\bin

Set Tool Chain Editor to:
  Current toolchains: Cross GCC
   Current builder: CDT Internal Builder

This works for me with Eclipse 2019

Cheers,

Jon

Re: [beagleboard] IDE (eclipse) for Beaglebone on Windows

[jonnymo]

When you create your project, ensure you are selecting "Cross GCC" and not
"MinGW GCC".  The MinGW is for windows dev.

Ex:

Re: [beagleboard] Re: Connecting Two BBBWs to One Another and Using One Script?

I've used both a BBB and a RasPi for the Mosquitto server.  It is a
lightweight server so it should not be too taxing on a system.

Re: [beagleboard] Unable to boot after 'apt upgrade' to Debian 9.13

[jonnymo]

Could you post the strange message you are seeing regarding the uSD card?

For me, going from 9.9 to 9.13 and beyond, I would just do a reflash of the
image.

Which rev of BBB do you have?  Rev B or Rev C?

Robert is the master of this so I would think his suggestions would clear
the issue.

Cheers,

Jon

Re: [beagleboard] Switching a GPIO to and LED via the device tree

[jonnymo]

Very cool Mark.

A couple of notes:
1.  It might be a good idea to put a note in there for the folks to back up
their currently booted dts/dtb files before editing them.

2. Under "Finding which device tree to edit" I believe there is a typo:
 Note: If you want to edit the source using cloud9 us the following
trick ...
   Should be:
 Note: If you want to edit the source using cloud9 *use* the following
trick ...

3. When you run make, would it be best to just run it against the file that
was edited rather than the whole folder?
 Maybe the build script is smart enough to figure this out.

4.  Under "Adding our LED" there is the following without explaining the
why.  Was this intentional?
"How did I know to use *gpio1* and *18*?"

This is a nice series.  Thanks for sharing.

Cheers,

Jon

Re: [beagleboard] Re: where is "syscall" function is declared ?

[jonnymo]

What worked for you?  I cloned the code from the link you provided and the
syscall code has build errors.

What I did to clear this out was:
1. In "syscall.cpp", I added 'unistd.h' to the includes:
  Ex:
  #include 

2. I did the same in callchmod.cpp,

3. Run ./build

Apparently there is an issue with unistd.h not being added in certain areas
with gcc.

Cheers,

Jon

Re: [beagleboard] Re: where is "syscall" function is declared ?

[jonnymo]

Yeah, I missed where this was shown in the email.

As far as the link for Drerk's web page is concerned, I suspect it is a
reference to the first ed of his book.

>From what I gathered, syscall is not POSIX compliant and could cause
compatibility issues so it's use is discouraged. This I would suspect is
why there are suggestions from the error when running the example to use
'swscanf' and 'getpt' instead.

However, as you found, 'syscall' is defined in 'unistd.h' so having this
included is required which does not seem that new. Then again, the code on
Derek's site is at least 6 years old and may not be kept up to date which
could explain the use of syscall there.

Jon

The only real references I have seen is in the following gnulib manual :

And the subsequence link:

Re: [beagleboard] pygame displaying on /dev/fb0

[jonnymo]

Have you checked the output of the following command?

   "*fbset -i -fb /dev/**fb0*"

Have you tried to force the video driver to fbcon as an environment
variable such as:
 *SDL_VIDEODRIVER="fbcon"*

I suppose you could try to force it in your pygame code as such:
   *os.putenv('SDL_VIDEODRIVER', 'fbcon')*

Cheers,

Jon

Have you tried running it as root? Not 'sudo' but su to root and try it
there.  It could still be a permission issue.

Just a thought, is your user part of the 'video' group?  I would suspect it
is since you were able to run the fbi stuff but it wouldn't hurt to check.

Re: [beagleboard] pygame displaying on /dev/fb0

[jonnymo]

If you run 'lsmod" does the fbcon module show in the output?

If not, try to load it manually:
  #* modprobe fbcon*

Does this show an error?

Check

Re: [beagleboard] pygame displaying on /dev/fb0

[jonnymo]

There is a fbcon module as is referenced in the pygame script you listed
from Adafruit.  I would suspect that none of the drivers listed in the
script ('fbcon', 'directfb', 'svgalib') would be loadable on your system.
>From what I have gathered, fbcon is enabled by enabling the Framebuffer
console feature in the kernel as in the .config.  I'm not 100% sure how to
do this with the BB kernel.

When my BBBlue was still alive (R.I.P.), I did connect a ili9341 display to
it and had to run the following to get a QT app to run on the screen:
   #  -platform linuxfb:fb=/dev/fb0

This is the example I followed which was posted by Jason.
https://gist.github.com/jadonk/0e4a190fc01dc5723d1f183737af1d83

Perhaps something similar would work for the BB Black and pygame.


Cheers,

Jon

Re: [beagleboard] Re: pygame displaying on /dev/fb0

[jonnymo]

In my config, BBAI running 4.14 kernel, I found two instances of fbcon:
$ sudo find / -name fbcon

* /sys/devices/virtual/graphics/fbcon*
* /sys/class/graphics/fbcon*


The framebuffer console seems to be attached to the console layer.

*$ cat /sys/class/vtconsole/vtcon1/bind*
*1*
*$ cat /sys/class/vtconsole/vtcon0/bind*
*0*


Info on fbcon:
https://www.kernel.org/doc/html/latest/fb/fbcon.html


Not sure if this helps at all.

Cheers,

Jon

Re: [beagleboard] Robooic Application in Beagle Bone Black

[jonnymo]

The Logitech C920 with OpenCV is a common combo with the Beaglebone Black
as far as cameras are concerned.

The BeagleBoard site has some Robotics examples but not all are for the BB
Black:
https://beagleboard.org/p/projects/tags/robotics

There is an example from Derek Molloy on his website/books using the
Logitech C920  however it is a bit dated:
http://exploringbeaglebone.com/chapter14/

The Packt book Mastering BeagleBone Robotics has an example using a
Logitech 720.
https://subscription.packtpub.com/book/hardware_and_creative/9781783988907/4/ch04lvl1sec21/connecting-a-webcam-to-the-beaglebone-black

  Here is an example using a Microsoft Web Cam which looks interesting.
http://einsteiniumstudios.com/beaglebone-opencv-line-following-robot.html

The Robotics Cape might be of interest to you for the motor control and
sensor section.
http://www.strawsondesign.com/#!board-default

I'm sure there are more.

Jon

Re: [beagleboard] Re: External USB 2TB HD not spinning up.

[jonnymo]

I vote for using a Powered USB Hub attached to the BeagleBone.  I've had to
do the same thing when using a separate Bluetooth and WiFi module and for
just basic USB expansion.   However, I found that not all Powered USB hubs
worked with the BBB; at least not so a few years back.

I did have luck with the Belkin P-F4U041 though:

Re: [beagleboard] Re: pygame displaying on /dev/fb0 - Solved

[jonnymo]

Cool.

  I am unable to get your pygame or other fb examples to work but I can get
the 'usr' examples to work.

Perhaps this is for another post, but in your examples, are you using SPI0
or SPI1?  It seems some of the setup for the examples are set for SPI0 and
some are set for SPI1 yet the wiring listing in "EBC Exercise 12a 2.4 TFT
LCD display via SPI" seems to indicate SPI0.

I personally do not have experience with the Intel RealSense cameras.  You

Re: [beagleboard] Re: pygame displaying on /dev/fb0 - Solved

[jonnymo]

I was able to resolve the issue I was having with your fb and pygame
examples.  I had to ensure the BUS was set to '0' and the pin GPIO values
were set properly in 'on.sh'. The same was true in reset.sh with 'busnum=0'

Also, it seemed that if I ran the examples in 'usr', I had to reboot the
board for the 'fb' examples to work.

It's all working now.
Nice job.

Re: [beagleboard] Robooic Application in Beagle Bone Black

[jonnymo]

You might look at the RoboMagellan competitions and see if there were any
examples of using a Beaglebone.  This could be an opportunity to be the
first to do so though.
http://robogames.net/rules/magellan.php

https://en.wikipedia.org/wiki/Robomagellan

https://ou.edu/scr/robomagellan.html

However, in the case of RoboMagellan, or autonomous navigation in general,
you could look at using a camera and something like ROS and OpenCV.

The DARPA Subterranean Challenge might be another place for ideas:
https://www.subtchallenge.com/


This is old, but does cover LiDAR on the Beaglebone:

Re: [beagleboard] Re: Servo control: pulse width working range ?

[jonnymo]

Actually 360 degree Continuous Rotation Servers are quite common. There are
basically two types of servos: 360 degree Continuous Rotation and 90 degree
Standard Rotation.  Each has a different purpose.

As far as manufacturers not providing datasheets for their products, I
would suspect this depends on where you are purchasing the servers from.
If you stick with manufacturers such as Hitec, Tower, Futaba, or Parallax
you should be fine.  If you are purchasing cheap off brand servers, then
you may run into an issue with each being different as far as how they
react to a PWM signal. Also, depending on the application, there could be a
difference between plastic and metal gears.  I tend to like metal gear
servos though.

Cheers,

Jon

Re: [beagleboard] Re: How to set eth 0 as default route

[jonnymo]

If you set your default gateway for the port from USB, then you can delete
that and add the gateway for the eth0 port. This should direct traffic to
the eth0 port.

You can verify this with 'ip route".

The other option is to use ifmetric and set the ports accordingly.
Ex: 'metric 0' - for eth0
  'metric 1' - for usb
https://www.debian.org/doc/manuals/debian-reference/ch05.en.html#_the_ifmetric_package

Re: [beagleboard] Re: Install Ubuntu using SD card and Windows

[jonnymo]

If you are willing to reimage the Beaglebone, why not just download Etcher
on your Windows system and then burn a Beagleboard flasher image to an uSD
card and then boot the BBB with the flasher image to refresh the eMMC?

Etcher Windows:
https://www.balena.io/etcher/

Beagleboard images:
https://beagleboard.org/latest-images

If you have another Linux based board such as Raspberry Pi, you could try
to read the BB image on that using a uSD USB reader.

The other option is to install a tool on your Windows system that allows
you to read the Linux filesystem and then edit any file you changed.  I
suspect either /etc/resolv.conf' or your interfaces file.

Re: [beagleboard] Re: Servo Power issue

[jonnymo]

In this this Rubik's Solver project there is a note in step 2 of the
Software Preparation section where they make a change in
'libraries/other/rc_pru.c' of the Strawson Design Roboticscape software to
set the "servo pulse from +/- 1.5 to +/- 2"
They seem to be able to run with 6 servos attached so perhaps this would
help.

https://www.hackster.io/octavo/iot-robot-w-osd335x-powered-beaglebone-blue-rubik-s-solver-5891a4

They also have a Li-Po battery connected.

Jon

Re: [beagleboard] Re: Compiler: Setup linux kernel for beaglebone black

[jonnymo]

If you search the Beagleboard forums you'll find this question has been
answered a few times fairly recently.  As far as QEMU is concerned, that is
not needed unless you are looking to set up an emulation environment on the
host system to test code before deploying it.

Ex:
https://mail.google.com/mail/u/0/?tab=rm&ogbl#all/FMfcgxwJXVJDNpwqgTFZtTcgKNcksqrP

The main thing you need is the Toolchain for the BB.
https://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabihf/

The best cross-platform option I have found is to use Eclipse, but you
could use Visual Studio Code as well. For Windows specific, you could use
Visual Studio but you may be limited to having to build on that target (BB)
remotely which defeats the purpose of cross-compiling. The best bet for
Windows and Visual Studio is to use VisualGDB but that is at an extra cost.
https://visualgdb.com/

There are some pre-build BB toolchains listed at the following link for
Windows dev but this is a bit dated.
https://gnutoolchains.com/beaglebone/


Good luck,

Jon

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

For cross compiling on the Beaglebone from Ubuntu, this might be helpful:
https://www.itdev.co.uk/blog/building-linux-kernel-cross-compiling-beaglebone-black

As Robert mentioned, if you go to the link in your error message, you'll
see there are no ARM packages:
http://fr.archive.ubuntu.com/ubuntu/dists/bionic/main/

Neither does the non ".fr" link:
http://archive.ubuntu.com/ubuntu/dists/bionic/main/

Cheers,

Jon

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

>From what I remember with Debian, you still need to add the arm arch to add
cross build support:

sudo dpkg --add-architecture armhf

https://wiki.debian.org/CrossCompiling


Ubuntu seems to be more widely used on PCs so there seems to be more
examples. No other reason for me.

Personally, I just like to download the toolchain and reference it
from the folder location.

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

When you set-up the repos, did you set the architecture on your Ubuntu
system to ARM?
You can check it via:
   *dpkg --print-architecture*
   or
   *dpkg-architecture -qDEB_HOST_ARCH*

Did you perhaps set the foreign architecture on your host to ARM?
You can check it via:

*dpkg --print-foreign-architectures*

You could install something like VirtualBox on your Ubuntu system and then
download a Debian image and work from there if you have too much of an
issue using Ubuntu.

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

You should be able to get rid of those messages by running the following:
  *sudo dpkg --remove-architecture armhf*

Some options to run with the extended cross-compiling options are:
1. Run through the debootstrap option from the book.
  or
2. Download the ARM toolchain for the BB manually and just reference it in
your code or IDE.
   This is what I use:
gcc-linaro-7.5.0-2019.12-i686-mingw32_arm-linux-gnueabihf toolchain from:

https://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabihf/
  or
3. Install the build tools on the BB and copy the BB arm-linux-gnueabihf
from  /usr/bin, /usr/include, usr/lib, and /lib to the host system via
rsync and reference this from your IDE:
RasPi Example:

https://medium.com/@zw3rk/making-a-raspbian-cross-compilation-sdk-830fe56d75ba
 or
4. Go the Debian VM or Install option.

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

Debian might be the preferred OS for Debian based embedded systems, but in
my world Red Hat is the Linux OS of choice.

If you are cross compiling, it really should not make a diff what the host
OS is. I can do this on Windows 10.  In this case, Debian just makes it
easier since you can install the toolchain directly via apt. If one uses
something like Ubuntu, it's just a bit more work but not impossible.

Re: [beagleboard] Re: Update errors on Ubuntu desktop after installing cross toolchain

[jonnymo]

Or just rsync the libraries and includes from the BB or download the
toolchain and libraries manually to the host and reference that.

The section in question from Derek's book is in reference to
Cross-Compilation with Third-Party Libraries (Multiarch).  This is one way
to do that but not 100% necessary. Again, it;s just the easier way and
perhaps best approach in this instance.

He does mention Ubuntu in the description though so that could be confusing
for some.

However, this is your realm so I will step back from this.

Cheers,

Jon

Re: [beagleboard] Executing of C++ arm code in Eclipse fails

[jonnymo]

Did you look on the book website?
http://exploringrpi.com/chapter7/

Look at the response by Brendan Lynskey regarding adding the following in
your "~/.bashrc"
   *export QEMU_LD_PREFIX=/usr/arm-linux-gnueabihf  *

You could do this on the command line as well but it will not be persistent
between logins.

In your /var/lib/connman folder you should have a file associated with your
wlan0 config.

ex:
* $  sudo ls
 /var/lib/connman/wifi_8091334a1523_4d6f4e6574494f54_managed_psk/*
*data  settings*

In the psk settings file, I tend to set this manually as such:

*Name=MySSID*
*SSID=pk2-passwd*
*Frequency=2462*
*Favorite=true*
*AutoConnect=true*
*Modified=2020-09-24T07:36:19.092924Z*
*Passphrase=mypasswd*
*IPv4.method=manual*
*IPv4.netmask_prefixlen=21*
*IPv6.method=off*
*IPv6.privacy=disabled*
*Hidden=true*
*IPv4.local_address=192.168.2.210*
*IPv4.gateway=192.168.2.1*
*Nameservers=8.8.8.8;8.8.4.4;4.4.4.4;*

The "Nameservers" setting wll set the /etc/resolv.conf with the nameserver
associated with wlan0 and the same is so for  IPv4.gateway if you are
running IPv4.

This can be done manually as such:

*# connmanctl config  --ipv4 manual  
*
*# connmanctl config  --nameservers *

Ref:
 https://variwiki.com/index.php?title=Static_IP_Address

If your eth0 is not defined with nameservers and gateway, it is possible it
will overwrite the /etc/resolv.conf when you plug in an ethernet cable and
not set it when it is disconnected.  One test would be to reboot the board
and see if the wlan0 connection recovers. Another is to  check
/etc/resolv.conf when you plug in the ethernet cable and then when you
disconnect it.

You can also use 'dmesg' to see if there are any networking errors being
reported when you are changing network connects.


Cheers,

Jon

Re: [beagleboard] creating astable build for a commercial system

[jonnymo]

So, you are using the actual Beaglebone board in a production product?  I
kind of seen them as just prototyping platforms.

How are the sensors connected to the Beaglebone?  Direct or do you have
some sort of driver between the sensor and the BB GPIO pin?  I would think
the later is the best option.

How is your software communicating with the sensors via the BB?

Have you checked either 'dmesg' or '/var/log/syslog' on BB to see if any
events were seen at the time the issue was seen? This may give a clue as to
what is happening.

Cheers,

Jon

Re: [beagleboard] Re: Can't connet to BBB over Ethernet

[jonnymo]

Looks like your 169.x.x.x routing is going through the wireless device:

pavel@ALABAMA:~$ ip route
default via 192.168.1.1 dev wlp7s0 proto dhcp metric 600
default via 192.168.206.2 dev enp8s0 proto static metric 20100
*169.254.0.0/16 <http://169.254.0.0/16> dev wlp7s0 scope link metric 1000*
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
192.168.1.0/24 dev wlp7s0 proto kernel scope link src 192.168.1.252 metric
600
192.168.206.0/24 dev enp8s0 proto kernel scope link src 192.168.206.180
metric 100

  Did you setup the NAT to route through the wireless device?
 Have you tried rebooting the BB?

See if you can ping the 169.x.x.x address of the BB using the wlp7s0
interface
Ex:
   *ping -I  wlp7s0 *

Re: [beagleboard] Re: Can't connet to BBB over Ethernet

[jonnymo]

Something you can do to check the connection is to manually set the IP on
the host and the BB as such:
This assumes you have another way to get to the BB like via the USB network
or FTDI serial connection.

Host (may not be needed. I do not see an eth0 from the host listing):
 *sudo ip addr add 192.168.206.180/24  dev
enp8s0*

 BB:
   *sudo ip addr add 192.168.206.181/24  dev
eth0*

Then see if you can ping the BB from the host as:
*ping -I * *enp8s0*  *192.168.206.181*

 You may have to take the BB eth0 down and then up if it does not take:
  Ex:
*sudo ip link set eth0 down*
*sudo ip link set eth0 up*

If you have Network Manager running on the host it could interfere and
reset eth0.

Cheers,

Jon

https://www.digikey.com/en/maker/blogs/how-to-connect-a-beaglebone-black-to-the-internet-using-usb

Have you set the default router on your BBB?
Ex:
   * sudo /sbin/route add default gw 192.168.7.1  *

Cheers,

Jon

Re: [beagleboard] Re: Can't connet to BBB over Ethernet

[jonnymo]

The interface  enp8s0 is the physical Ethernet port from the Ubuntu host
that is directly connected to the BB, correct?
If this is correct, then enabling DHCP makes no sense unless you have set
up the BB as a DHCP server.  Since you are connecting these two devices
directly, then you need to either hardcode the IP address on the host
without DHCP and then set the IP on the BB.
If you do what I had shown previously, then that will give a clue if the
connection is working.

However, using Network Manager may interfere with any manual changes you
make.

Please look at the link I provided for more detail on how to troubleshoot a
network connection.

Re: [beagleboard] Re: Can't connet to BBB over Ethernet

[jonnymo]

The 169.x.x.x address on the BB I believe is just the default address when
it can not connect to anything.  You could set it to something else
manually.

For internet access, you need to configure the routing so the BB will
connect to the internet through the host ethernet port.

I'm not sure what is causing the issue on the Ubuntu system since I do not
use that tool.
