[beagleboard] BB-View cape problem

[Artem Popov]

Hello,

I have a problem with BBB + BB-View + LCD7.
OS: TI-SDK from element14 site
HW: BBB "PCD Rev B4", Element 14 BB-View cape, 7" LCD "LCDX000-70T"

1. Colors are strange. Looks like not enough color depth or wrong blue 
color intencity
2. When I place my hand near the cable, didn't even touching it, blue color 
noise appears.

I've checked all connections. Everything is good.
Board powered from 5V 0.5A DC adapter. I know that it's not enough, but it 
works.

Have somebody met such problem? What can I do to fix it or just to find the 
reason?

I've reconnected internal LCD cable. Blue color appeared and blue noise 
disappeared. But there is still not enough color depth.

[beagleboard] [Q] How can I use P9 14 as PWM?

[Sungjin Chun]

echo "am33x-pwm" > ...slots 
echo "pwm-test-P9_14" > ...slots
(yes, I'm not rewrite those file names correctly here)

Above does not make PWM work for P9_14 pin. Though there are period_ns and 
duty_ns, if I
echo "1" > run
nothing happens. If I do this on P8_13, it works. Why does this not work 
for me?

Re: [beagleboard] Re: problems with webcams

[Matthew Witherwax]

Adam,

If your issue is a low frame rate coming from the PS3Eye, I have written
about this problem here http://blog.lemoneerlabs.com/post/BBB-webcams
To make a long story short, the transfer method the PS3Eye uses to transfer
data over USB doesn't work on the BBB at high frame rates and/or high
resolutions.

If the frame rate you are getting is sufficient, then the question becomes,
what algorithm is being used to track faces?

Let me know what is going on, and I will help where I can.

Matthew

 My first question for you would be which pixel format are you capturing
 in?  If you do a "v4l2-ctl -d /dev/videoX --list-formats-ext" in the
 command line (where X is 0, 1, ...  whatever your C920 is) you can see the
 various pixel formats, resolutions, and frame rates supported by the 
 camera.

 For YUYV, the maximum frame rate at 1280x720 is 10 fps.  If you are
 using H.264 or MJPEG, the maximum frame rate is 30 fps.

 I'm doubtful that that's your problem since you are still only getting
 15 fps at lower resolutions.  (Can you get 30 fps at 640x480?  That is the
 resolution I am using for my own project and might serve as a good baseline
 measurement.)

 My only other thought for now is that your actual measurement of the
 frame rate could be wrong.  I don't have much experience with pthreads, but
 I know that some of the "clock" functions in the  header have to be
 handled differently when you are multi-threading.

 Those are my only ideas for now.  I'll keep racking my brain and let
 you know if I come up with something else.

[beagleboard] Re: I2C2: Bad address, without checking

[Rafael Fiebig-Bindner]

After some further testing I can clarify the behavior of the I2C-bus:
When I manually access the I2C-dev nothing happens, SDA and SCL keep 3.3V 
the whole time.
When I use the command "i2cdetect -y -r 1" the SCL gets the typical 
clock-look with about 4us high and low, except for its not going between 
3.3V and 0V, but 3.3V and 2.8V. SDA on the other hand also periodically 
keeps 3.3V for 2.5ms, then stays 0V for 1s.
All this behavior is unaffected, if I put additional external pullup 
resistors or not.
Has anyone any idea whats going wrong?

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test

[mbbackus]

My BeagleBone part of a primitive robot with a breadboard strapped to the 
top, and servo motors underneath. The wifi dongle was between both. For 
this reason, I dug out my unpowered USB hub and used it as an extender to 
get the wifi dong'e away from all the metal. I powered the beagle bone with 
an external power supply and remoted into it via usb. I was able to get the 
Adafruit dongle to connect to my secured home network 1 out of three times 
this time around as well as a secured hotspot hosted by my phone. This was 
better than the netgrear wna1100 which was only able to connect to the 
secured hotspot (not my regular home network). Neither was able to connect 
to an unsecured hotspot. Attempts to connect via wifi also seem to cause 
the BeagleBone to freeze up frequently. Any ideas?

Also, it would be really handy if the default user was root (like on 
Angstrom) so that I didn't have to type sudo su before most terminal 
commands. This would also allow me to open files more easily. I'm guessing 
this would also allow the user to reboot and shutdown the beaglebone, 
options which are missing from LXDE at this point, and which cannot be 
execute from the command line using the debian user.

Re: [beagleboard] Kernel/device tree road-map for the BBB

[billywu312]

I think its because of this, the Adafruit Python GPIO library broke. Is 
there anyway to fix this? I fixed the I2C probably by changing the python 
file, but unsure how for the SPI.

 Hi Kenny,

 As Jason noted the installer is unsigned, this means you need to 
 restart Windows 8 in the mode where it allows you to install unsigned 
 drivers.

 Here's a quick step-by-step guide:

 1. Press win+c on the keyboard to bring up the charms side bar (or move 
 mouse to right top corner of the screen)

 2. Click the Settings button.

 3. Click the Change PC Settings at the bottom of the sidebar.

 4. On screen that shows up, select the General option from the sidebar 
 then scroll down the page that appears.

 5. Click the Restart now button under the Advanced startup section.

 6. You will momentarily see the restarting screen, then it will switch 
 to a blue screen titled "Choose an option"

 7. Click the Troubleshoot button.

 8. Click Advanced options.

 9. Click Startup Settings

 10. Click Restart

 11. You should then see a Startup Settings screen after your computer 
 reboots.

 12. Press 7 or F7 on your keyboard to Disable driver signature 
 enforcement

 13. Now Windows 8 will continue starting up.

 14. Log-in as normal, and then run BONE_D64.exe again

 15. Now you should see 4 warning dialogs about "unsigned driver 
 installation", click OK for all of them.

 Then you should be good to go!


 Hope that helps,

 Piyush

Re: [beagleboard] Re: Automotive Cape

[marcmltd]

Hi, sorry for not responding when I said.

The PCB's have now arrived from the manufacturer and the parts have arrived 
from Farnell and Mouser.
The assembly and inspection is starting this weekend.

I have to state that this is an initial low volume (10 off) production to 
check the viability.

We are testing the circuitry before we produce a full 3558/9 based board 
with all the options of the cape populated.

If there is enough interest in volume then we could produce for the 
community.

I am talking to the hardware engineer today so will get updates about 
expected assembly completion.

Sorry for the delay in updates.

Marc

[beagleboard] Circuitco LCD4 - Kernel 3.12, 3.13

[Moscowbob]

First of all, thank you to all who share their knowledge and experience, 
without you guys us newbies will have a hard time learning.

I have been playing around with various kernels and just in general getting 
familiar with Linux and the BBB in general. I managed to build QT 4.8.5 
with RCN 3.8.13-Bone41 and all seems well. Now I wish to use QT with SGX 
and as I understand Robert has provided scripts to build all the required 
drivers etc but the later kernels do no support Cape manager and overlays 
so the lcd is not enabled.

Would somebody please explain how to enable the LCD4 from Circuitco in the 
new kernels(if that is currently possible).

Thank you.

Re: [beagleboard] Re: BB-View cape problem

[Gerald Coley]

Just so people can help you, can you tell us the revision of the board? PCB
Rev B4 is the PCB, not the board. The revision is either on the expansion
headers or the RJ45 connector..

Re: [beagleboard] Re: Windows 8 (64bit) driver install problems

Try method #2 Here 

Just be warned that it disables Signature enforcement completely.
To re-enable it run last two commands and restart.

The is problem with the default 3.8 kernel, if your not using any
cape's switch to the 3.13.x based kernel

cd /opt/script/tools/
git pull
sudo ./update_kernel.sh --beta-kernel

There is a default root user (no password like Angstrom) we just don't
log into that user via lxde.

SGX was back-ported to the 3.8 tree as of the "bone41" release.

There is no revision like "A5" or similar on board. I have BBB from Embest

Re: [beagleboard] Re: BB-View cape problem

OK. So now everyone knows you have the Embest board. Interesting that they
have no revision number on it. I don't know what revision that board is
equivalent to on the BeagleBone Black.

[beagleboard] Beaglebone Black Processor is probably blown, is there any way to get the data off the emmc?

[jdorr6695]

I have good reason to believe that my Beaglebone Black has a blown 
processor.  Is there any way to get my data off the emmc, or am I pretty 
much starting over?  When I plug in the board the power light blinks for a 
split second, it will also blink for a split second if I push the power 
button.  Nothing else happens, even when I hold down the power button.
 
Thanks,
Jeremy

resonant sensors. 

I need to read a sinusoidal resonant  signal of 3Khz with ADC  SPI 
so the parameter which I need are: 
the ADC should read at a rate of 100 kHz for a while 5 miliSeg 

I have many doubts, not sure how fast I can use the SPI port? 
Can I use the spi port true C and some Lyb?
I do not know if using PRU?
I can do it in C?

Re: [beagleboard] Help Needed : Custom built debian image

[viraniac]

Hi Robert,

Thanks for the fast reply. I have gone through the scripts and I noticed 
that you are the author of the scripts. I really thank you for making those 
awesome scripts to make our lives easier. 

Just have a suggestion, Please add bit more information in the readme file 
about the customisation and all which will be helpful while making 
customized images.

I have commented some lines to disable installation of GUI, Lxde, apache, 
etc and currently the script is running on my BBB. Will post the result 
once it finishes.

I have one more question. I noticed that debian image comes with apache-2 
installed in it. What's the purpose of having apache 2 here?

Regards
viraniac

Gregory,

You can probably use the 24.576 MHz output of the HDMI oscillator that is 
available on P9 pin 25. The oscillator is enabled by GPIO 1-27, so you can 
enable using this output it even if you have disabled the HDMI output for 
some reason. It should be enabled by default.

If you use this oscillator output, you can't use GPIO 3-21 since they share 
the same expansion header pin.

[beagleboard] Re: How to use clock output (CLKOUT2)

[gfastmapper]

I suggest that you look at output pins TIMER4, TIMER5, TIMER6, and TIMER7 
(section 20.1.2.4 of the Technical Reference Manual).  Those timers are 
clocked at 24MHz, have programmable divisors, and can produce output clocks 
up to 12MHz.  Section 20.1 of the Technical Reference Manual provides more 
information on the timers and the datasheet will detail the settings 
required to associate a timer output with a pin.

Re: [beagleboard] Re: Involuntary reseting of the BBBlack.

[dickelbeck]

The boards will reboot if :

a) OTG is disabled in the kernel build, and 
b) g_multi.ko is loaded, and
c) the usb cable is disconnected.

If you remove b) then they stay up.

This is with kernel 3.12.9

Re: [beagleboard] Help Needed : Custom built debian image

[viraniac]

HI Robert,

The script is still running but what I can see is it just installed nodejs 
packages. I guess this is because the script was installing the beaglebone 
package. I don't require node.js installed. Please confirm the features 
provided by beaglebone package so I can decide whether to include or 
exclude it from the build.

Regards
viraniac

The "beaglebone" meta package currently pulls in:
acpi-support-base, am335x-pru-package, libsoc2, nodejs, nodejs-legacy,
npm, xinput-calibrator, xserver-xorg-video-modesetting

from the beagleboard.org debian repo:
http://beagle.s3.amazonaws.com/debian (there's a new domain being
setup using beagleboard.org)

If you don't want these package, just disable:
https://github.com/beagleboard/image-builder/blob/master/beagleboard.org_image.sh#L424

Then you'll still have access to the beagleboard.org repo.

[beagleboard] ssh fails write broken pipe

[Walter Schilling]

I have students working on the Beaglebone using the current Debian image. 
 They are working in pairs.  Student one has bone A and laptop a.  Student 
two has bone B and laptop b.  If b connects to B and then a connects to A, 
they receive an ssh failure with a broken pipe.  If b connects to both A 
and B, then it works fine.  It  makes no sense to me at all.  Any ideas?

What does the "-v" option for ssh print out for debugging?

[beagleboard] BBB as a router w/ firewall capabilities

[vignesh murali]

I just wanted to know whether it would be a good idea to run BBB as a 
router w/ firewall capability. I intend to use BBB with 1 WAN port and 2 
LAN ports(with USB to ethernet dongles) to support a total of 150 users in 
the network.  I am skeptical about the load the BBB can handle with the 
above said numbers. Any suggestions?

Wild guess...  I would say the USB dongles would be where you hit the 
wall.  The BBB has more than enough CPU power, RAM might become a factor 
with that many users with a lot of rules.


LEAF has an ARM port for Rpi.  I don't recall if it's in main or not.  I 
would think the same hurdles would apply here for that number of users.


Seems to me for the money a Sokeris (sp?) board or something similar 
might be more appropriate.


My 2 cents worth anyway.

Mike

Re: [beagleboard] Re: [Q] How can I use P9 14 as PWM?

Thank you for your help.

pwmchip0 and pwmchip1 2 files are there.

Weird thing is that after echo "pwm-test-P9.." and echo "pwm-test-P8...",
 though there are pwm-test-P9_14 and
pwm-test-P8_13, and contents of the directores are same, only P8_13 does
show result in oscilloscope but
P9_14 does not show result.

[beagleboard] Re: [SOLVED} Question about GPIO interrupt configuration on device tree

[Ventura]

I found out that the configuration for gpio1_15 as the interrupt line for 
SPI1 has to be:

&spi1 {
pinctrl-names = "default";
pinctrl-0 = <&spi1_pins>;
status = "okay";

spidev2: spi@0 {
compatible = "microchip,enc28j60";
reg = <0>;
spi-max-frequency = <2400>;
interrupts = <15 2>;
interrupt-parent = <&gpio1>;
};
};

Using this configuration the enc28j60 1.0.1 works as is without do any 
change.

Re: [beagleboard] Help Needed : Custom built debian image

[Maxim Podbereznyy]

viraniac,

why don't you just use a "bare" image and add in packages that you need?
What you do now is going from the end to the beginning. I would go from the
smallest "bare" image to functionality required

Re: [beagleboard] Re: How to use clock output (CLKOUT2)

[Eric Fort]

What frequency do you want?  first of all what you need to know is the
frequency of CLKIN.  Best I can tell that defaults to 24Mhz.  from there
you can pretty easily find values to fit closely what you need for clock
output frequencies.  For that matter if you're unsure write a loop that
produces a table of values for a given CLKIN frequency.  in generating such
a table using a CLKIN frequency of say 1MHZ could work quite nicely as the
values can be easily scaled from such a table.
