[beagleboard] Issues in 4.4 and 4.6 Custom Image

2016-05-30 Thread Virendra 

Hi,

I am building the custom Image using 4.4 and 4.6 and I see the following 2 
issue in both the versions. I have already built kernel version 
4.1.20-bone20 Image from Robert Nelson successfully and it is running 
without any issues. 

Could you let me know how to resolve the following 2 issues in 4.4 and 4.6. 

*Issue 1* - sudo reboot fails to reboot

I see the following log while issuing the reboot command. The watchdog 
fails to stop and the last line says Rebooting but it never reboots
Pastebin Link showing the logs -  http://pastebin.com/n0cCWsvQ

*Issue 2* - Waiting for connecting to network for more than 2 minutes with 
a message -- [ *] A start job is running for LSB: Raise network 
interf... 3s / no limit)

My network interface file: http://pastebin.com/XteCbMDV

Log showing waiting for more than 2 minutes -  http://pastebin.com/z0UHyiJy


Thanks,
Rafi

Re: [beagleboard] Which service is getting time & date on Debian Wheezy? I want to disable it.

2016-05-30 Thread William Hermans 
By the way, I think Robert has a script *somewhere* what runs ntpdate at
boot. But I do not remember where it is. I checked /opt/scripts/ on my BBB,
but I'm running Jessie, and could not find such a script. But it could also
be either a sysv init script, or an rc.d startup script, and potentially
even a a cron job( unlikely ).

That should solve the problem. But, you may also want to check and see if
the package fake-hwclock is installed, and remove that as well.

There is a service file named dbus-org.freedesktop.timedate1.service which

Thanks Robert and Pete.

I made a change to setup.py to define BBBVERSION41 based on

I've opened a Pull Request against Pete's adafruit-beaglebone-io-python
:
https://github.com/PeteLawler/adafruit-beaglebone-io-python/pull/1




Makes sense to me.

Merged and edited a little (no, really, extra whitespace is one of those 
things that make me twitch).


I hope to have a spare working BBB in the next day or so again (got a 
new spare and I then discovered what fun noises can be made by putting 
5V down AIN1).


Cheers,

[beagleboard] Re: enabling I2C1 on new ubuntu xenial image

2016-05-30 Thread Graham 
What you are trying to assess as I2C1 was renumbered to become I2C2. 
 Currently I2C1 is reserved for the internal operation of the device, not 
capes.
Capes are controlled by I2C2.  So you need to get a set of updated and 
matching overlays.  You might be better off using one of the current Debian 
releases.

[beagleboard] Using Beaglebone Black to monitor smoker temperature

2016-05-30 Thread athf . president 
Hello all,

I am new to the beaglebone community, so I'd first like to say hello.

A little background, I have a little bit of experience with Linux Debian, 
so I'm not completely new to Linux, but I'm nowhere near knowledged yet. I 
do have extensive knowledge with Windows platforms. I also do write some 
code in C, C++, HTML, Batch scripts, and am planning on finally learning 
some Perl. 

I am working on a smoker that I have been building for some time now. I 
came across a 330 gallon oil tank and have put about 120 hours so far into 
it. I finally am approaching the point where the fabrication process is 
coming to fruition, and have installed K Type thermocouples. I have a Fluke 
temperature standard that I am using in parallel with a voltage multimeter. 
The thermocouples are a voltage standard, and return a small millivoltage 
return as temperature fluctuates

I am planning on monitoring a range of room temperature (70ish F) to 500F, 
even though that is way above the temperature I will be reaching. That 
gives me a range of 0mV to 9.5mV. I am then using Op Amps with a 175 gain 
to achieve a range of 0V to 1.8V (yes I realize it isn't 1.8V exact, but I 
am observing the 1.8V maximum).

I then found this link which helped me understand a little bit more as far 
as to viewing the AIN inputs:
https://www.linux.com/learn/how-get-analog-input-beaglebone-black

I understand that the above link is not exactly what I will be doing, but I 
think it is an OK starting as far as to view the 12 bits of information I 
will receive when the temperature changes

My question is, am I on the right track? What would be my next step as far 
as creating a continuous loop to run when beaglebone boots?

My eventual plan for this is to use a 4x40 LCD display I have and mount it 
on the smoker to give continuous temperature reading, and maybe even push 
it to an Android App to be able to monitor it remotely (802.11) from a 
reasonable distance

Thanks!
Alex

[beagleboard] Which service is getting time & date on Debian Wheezy? I want to disable it.

2016-05-30 Thread John Baker 
I'm trying to disable the service that gets the time and date over the 
Internet. I want to do that in hopes that the BBB will instead get the time 
and date from my Adafruit DS3231 and I suspect the BBB is trying for a 
minute to get the time and date over the Internet. with the result that the 
BBB doesn't read the time and date from my DS3231 for a minute.

There is no ntpdate service on the Wheezy, or I would simply disable it.
Thanks,
John

Re: [beagleboard] BeagleBone Black Kernel Main Differences

Other than the obvious answer that V4.4 has for features/drivers than V4.1, TI 
continue to move their custom processor patches into mainline, so V4.4 will 
require less patches than V4.1. The goal is to eventually move all patches into 
mainline so that a standard kernel will work on a board with a TI processor. 
> Which are the features of every kernel branch (ex. v4.4)?
Best to look here:

http://kernelnewbies.org/Linux_4. 1

Do the same for 4.2, 4.3 and 4.4 to get an idea of what changed.
> What are the differences between 'bone-kernel', 'ti-channel', 
> 'bone-xenomai-channel' and other ones available?
bone-kernel is maintained by Robert Nelson and is targeted at the BB and BBB. 
The PRU is implemented with UIO
ti-channel is maintained by TI and is developed for all TI processors. Some 
subsystems seem to be updated sooner than the bone-kernel. The PRU is 
implemented with RPMSG/REMOTEPROC
xenomai is a dual kernel, one for realtime to achieve about 40uS latency under 
load conditions and the other is the regular Linux kernel
ti-rt used the preempt features to reduce the interrupt latency to about 100uS

> Which ones of the previous questions are available for real-time (rt)?
As I explained before, xenomai is faster, but development is way more 
complicated. In most situations, ti-rt is more than fast enough, but there are 
some drivers that don’t work properly with the ti-rt kernel.

John

So instead of asking questions that would require a book in text to answer.
Why don't you tell us what you need from a kernel, and if kernel x.y-z
would work for that purpose.

[beagleboard] How display the BeagleBone desktop in a TFT touchscreen with the SPI protocol?

2016-05-30 Thread Oshio 

I bought, accidentally, a capacitive touch screen TFT shiel for arduino. 
After some time I was able to implement this to work BeagleBone, I 
successfully sent an image to the screen.
My intention is to use it like a small monitor for an application that I'm 
writing in python with GTK library.

TFT Arduino Shield:
 Name:  2.8" TFT Touch Shield for Arduino v2.3.
 TFT Driver: Il9341
 Touch Driver: STMPE610

BeagleBone:
  BeagleBone Rev.A5A
  Image: Debian 8.4 

Why use SPI? The shield receive the image by SPI.

My question is:

I wanna know if it's possible to configure the BeagleBone, create a script 
or python code, that allows me to send the desktop through SPI? So I can 
use my TFT like a small monitor.

Best Regards.

significant improvements to the issues I was having.

More details about your issues would help those with more experience than I 
give you specific advice.


While things continue to improve, the state of the art on Beaglebone for 
hard real-time appears to be the "Machinekit" images that run a port of 
LinuxCNC on a Xenomai patched kernel and use the PRU for stepper motor 
control.   

Even so, I don't think a Xenomai process can do much better than ~70-100 
uSec, hence the usage of the PRU for stepper motor control which may need 
more like 20 uSec or less.

[beagleboard] BeagleBone Black Kernel Main Differences

2016-05-30 Thread yolcopc 
These are a newbie questions, but it would be fine if a wiki exists with 
clear explanantion about.

   - Which are the main differences between branches (ex. v4.1 vs v4.4)?
   - Which are the features of every kernel branch (ex. v4.4)?
   - What are the differences between 'bone-kernel', 'ti-channel', 
   'bone-xenomai-channel' and other ones available?
   - Which ones of the previous questions are available for real-time (rt)?

I'm trying to find a solution for an issue I have, and as I have read in 
some forums, changing the kernel would help me, but I don't know which 
could be the right kernel, so that is why I'm asking here.

[beagleboard] Re: Enable can0, can1, adc and spi0 with dtb-rebuilder (Debian Jessy 8.4, 4.4.9-ti-r25)

2016-05-30 Thread 'Andre Wippich' via BeagleBoard 
CAN is running now :-)

There were two errors:

1) I didn't know that I have to add 

dtb=am335x-boneblack-custom.dtb

to the /boot/uEnv.txt

2) In line 43 of

src/arm/am335x-bone-pinmux-spi0.dtsi 

stands " {" instead of " {"

CAN and ADC are fine now. I've a little trouble with SPI, but this could be 
my software.

Re: [beagleboard] Enable can0, can1, adc and spi0 with dtb-rebuilder (Debian Jessy 8.4, 4.4.9-ti-r25)

2016-05-30 Thread 'Andre Wippich' via BeagleBoard 
Hello Robert,

thank you for your response!

Unfortunately I don't get it work :-(

What I did:
1) Downloaded the new changed dtb-rebuilder with the new files to the 
beaglebone
2) Un-commented everything (can0/1, spi and adc) in 
am335x-boneblack-custom.dts
3) Went to the dtb-builder directory (cd dtb-rebuilder-4.4-ti/)
4) ./dtc-overlay.sh
5) make
6) make install
7) Downloaded and installed canutils (git clone 
https://github.com/linux-can/can-utils.git)
8) shutdown -r now

After the reboot, i tried to send a can message to my can test laptop:
cansend can0 100#deadbeef

But BBB told me: "write: Network is down"

So I started:

ip link set can0 up type can bitrate 50
cansend can0 100#deadbeef

But nothing happens. I checked all can-pins with the scope, there was no 
output signal. dmesg output looks good for me:
root@beaglebone:/sfb/devicetree# dmesg | grep can
[   32.566162] c_can_platform 481cc000.can: c_can_platform device 
registered (regs=fa1cc000, irq=208)
[   32.623212] c_can_platform 481d.can: c_can_platform device 
registered (regs=fa1d, irq=209)
[   60.805589] can: controller area network core (rev 20120528 abi 9)
[   60.819806] can: raw protocol (rev 20120528)
[  194.863977] c_can_platform 481cc000.can can0: setting BTR=1c02 BRPE=
[  194.864175] IPv6: ADDRCONF(NETDEV_CHANGE): can0: link becomes ready


After that I tried the adc, but the expected folder 
/sys/bus/iio/devices/iio:device0 wasn't there, so I think the adc doesn't 
work too.

Can you tell me, what I did wrong?

Regards,
Andre

[beagleboard] Re: Adafruit BBIO Python library

2016-05-30 Thread Drew Fustini 
Thanks Robert and Pete.

I made a change to setup.py to define BBBVERSION41 based on 
platform.release() which does reflect the correct kernel version. 

I've opened a Pull Request against Pete's adafruit-beaglebone-io-python 
:
