[beagleboard] python gui?
In my day job I erite backend code. Not gui stuff. I'm building a large robot and will use a BBB and display for data display and more. I would like to use python. What gui tools work with python on the BBB? I could also do this with node.js o some other web server. But python might be fun. -- Eric Palmer -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] AIN max voltage exceeded
Hi, I was using a BeagleBone Black, and I did the big mistake : 5V input on an AIN pin. For those who never tried, nothing really fun happens : the board just suddenly shut down, and can't be turned on anymore. Is there any way to fix this (by replacing a part, or something like that) ?

Re: [beagleboard] Re: UART4 stopped working: did not get pins for uart4 error: -19
Robert,
Yes, it is correctly passed to the kernel:
ubuntu@ubuntu-armhf:~$ cat /proc/cmdline
console=ttyO0,115200n8 fixrtc
capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN root=/dev/mmcblk0p2

Re: [beagleboard] Re: Beaglebone Black USB Host turns off
I've found meanwhile any version greater than 3.8.x is useless because does not contain cape manager (capemgr). It pays also for Robert Nelson's 3.13.x repository I've tested it but USB hotplug does not work too. HUB also does not work. Maybe there is minor difference (slightly more hopeful) but useless. I have compiled Linux arm 3.8.13-bone45 #1 SMP Wed Apr 9 00:58:12 CEST 2014 armv7l GNU/Linux from sources and USB hot plug (and HUB) does not work at all. I need it for cape development because of capemgr. I.e. the only good-hot-USB-plug kernel version is from my point of view 3.14.x. I suppose it's also problem of http://beagleboard.org/latest-images.

Let me clarify. *What works:* 1) Boot the Beagle Bone Black (the BBB) with now USB pluged in 2) Plug in a powered USB hub 3) Everything works as expected 4) Unplug usb 5) Plug USB back in. Everything works as expected. So hot plug works. *What fails* 1) Power up the BBB with the powered USB connected. The USB hub come up alot faster than the BBB. 2) No matter what is done, there is no way to get the BBB to see the USB devices apart from following up a reboot / power cycle as stated above. *Comments:* OS: Richard Nelson's Linux version 3.8.13-bone30 (root@imx6q-sabrelite-1gb-1) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8) ) #1 SMP Thu Nov 14 06:23:24 UTC 2013 Hardware: BBB Rev B.

I.E. if I stick all this stuff into an embedded gadget it would not come up on power up. I would have to have some sort of two-phase relay hardware in place to (1) power up the BBB first, then (2) the USB + USB devices / dongles. Any thoughts / solutions?

[beagleboard] USB mass storage on BeagleBone shown as mass storage under Windows
Hi, I have a normal white BeagleBone with Debian and I'm trying to show a USB mass storage, which is connected to the BB, as mass storage, if I connect the BB to a PC. At the moment, if I connect it to a PC, there is only a small part of the BB shown as mass storage (/boot/uboot/). This part has only about 80 mb. My aim is to show a on the BB mounted USB mass storage on the PC. I already managed to mount the USB device on the BB, than mount an image on the device an show this image under a linux distribution. If I do the same with a windows PC, it fails to install the drivers and nothing is shown. And there is another problem: I don't have admin rights so I'm not allowed to install any software or drivers because it's a PC from my company. On the BB I could do everything. Can somebody please help me or give some advice?

[beagleboard] Frame rate / sound quality is refreshing slowly, strategies to fix?
Hi! Having fun setting up my BBB, very neat piece of hardware. My desired end state is a movie box for Pandora, YouTube, preferably that I can control via network. I'll work on that part later. I now have Arch/LXDE running on it, and it is hooked to a large Vizio monitor / ac power / wireless keyboard and mouse. However, the video and audio quality in Chromium (pepper-flash, on both YouTube and Pandora) is only refreshing at 1-8 Hz and moving windows around the desktop is about the same. My roommate's Pi can do this pretty well, so I think my 1GHz BBB should do it better! Should I be using the 16gb c10 SD card as a buffer location? Or should I decrease the output resolution? What resources can/should I offload to the SD card to save MMC space? Please let me know what logs / config files would be helpful, I'm too new at this to know. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: UART4 stopped working: did not get pins for uart4 error: -19
Hi again,
I decided to look through the /proc/iomem pseudo-file to see if the mapping
looked reasonable. I believe the kernel may be corrupted since there is
garbage in the map for the usb:
ubuntu@arm-hf:~$ cat /proc/iomem
44e07000-44e07fff : /ocp/gpio@44e07000

44e10800-44e10a37 : /pinmux@44e10800
44e10800-44e10a37 : pinctrl-single
...
On Angstrom (where everything is working) I see:
root@beaglebone:/proc# more iomem

44e07000-44e07fff : 44e07000.gpio

Do you have any suggestions for how to clean up the kernel in this case?

[beagleboard] Frame rate / sound quality extremely slow
Hi! Having a wonderful time with my new BBB. I have it set up with Arch/LXDE, as this was relatively easy and very lightweight. My desired end state is a movie box type of deal, so mainly playing YouTube and Pandora. However, the refresh rate, especially in Chromium with pepper-flash and also just moving the xterm window around the DE, is extremely slow. Videos can load and play, but at probably 3-6 Hz. Audio is affected the same way. My roommate's Pi can do this well, so my faster and more stylish BBB should be able to do it better. Can I increase the buffer by using my 16GB C10 sd card? Should I decrease the output resolution? And can I offload other resources onto the SD card to free up MMC space (pacman destination, video buffer, potentially game files and all that)?

[beagleboard] use BB-xM to send raw ethernet packet
Hello, I have not used beagleboard or embedded system before, and I want to build a raw ethernet to send packets, here are some questions: 1. If I wrote a socket-building code in C language on Ubuntu, can it work on beagleboard ? (such as header files sys/socket.h linux/if.h linux/if_ether.h linux/if_packet.h, can they be read correctly?) 2.do I need to set hardware configuration? or API on Ubuntu will handle this for me? I am afraid of that I cannot get the privilege to send raw ethernet packet through beagleboard ethernet socket. One example is Windows OS, which takes off the right to send packets through data link layer except using special method.

[beagleboard] Re: USB mass storage on BeagleBone shown as mass storage under Windows
My first guess would be that Windows is not able to read the Linux file system, and that it recognizes the uboot part because it is FAT, which can be read by both Windows and Linux. I don't know if there are any utilities that allow Windows to read foreign (non-Windows) file systems, but that may be what you want.

The partition shown over the usb interface is defined in:

I took would like to see an example that uses the bonescript calls.
I haven't had a chance to try it out as I don't have a device easy to

Before ruing the code you need to:
beagle# *npm install -g serialport*
BoneScript simply uses this same library, so using BoneScript avoids
needing to install it.
beagle# *echo BB-UART4 /sys/devices/bone_capemgr.*/slots*
BoneScript loads this same overlay for you.
A basic listening example would be:
var b = require('bonescript');
var port = '/dev/ttyO4';
var options = {
baudrate: 115200
};
b.serialOpen(port, options, onSerial);
function onSerial(x) {
if (x.err) {
console.log('***ERROR*** ' + JSON.stringify(x));
}
if (x.event == 'open') {
console.log('***OPENED***');
}
if (x.event == 'data') {
console.log(String(x.data));
}
}
To write, you'd do:
b.serialWrite(port, data);
Hopefully you'll see some value in the simplicity.

Re: [beagleboard] BBB stepper controller using PRU
Thank you for your contribution, it is very appreciated. On Tue, Apr 8, 2014 at 6:26 PM, t...@mmto.org wrote: Greetings. I just joined the group, which I figured was overdue since I have been doing a lot of work on the BBB over the past 6 months or so. I had the idea of using some kind of controller to implement a camera focus controller to do focus stacking. This has all worked out and is operational now, but not without quite a bit of learning. Some high points: 1) I abandoned Cloud-9 immediately as hopelessly buggy (I hope nobodies feelings are hurt) and was far happier just editing javascript files with vim and running node on the command line. Ultimately my project has a beagle hosted web based GUI and I have no regrets about this way of doing things. Although I do all my development under linux, my photography machine runs windows and I can just run the GUI in a browser (Chrome works fine) to do the camera focus control. 2) I used the PRU to generate steps for a stepper motor. Doing this from node was hopeless (actually it was quite entertaining to listen to the motor run with changes of tone and stops and starts as the linux scheduler preempted my code). With step generation in the PRU, it is consistent and bulletproof. I very much like the PRU - but there is a learning curve. I reworked the standard PRU library to fix bugs and add some features I though were desirable. All my notes are at this link: http://cholla.mmto.org/computers/beagle/ In particular, my reworked PRU package is here: http://cholla.mmto.org/computers/beagle/pru/devel/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: How to use UART Serial Port Using BoneScript Library
It almost works out of the box. I changed baudrate to 9600 for my GPS and

var options = {
baudrate: 9600,
parser: b.*serialParsers*.readline(\n)

But *serialParsers* isn't defined! I added the following line at the end
of /usr/local/lib/node_modules/bonescript/serial.js
exports.serialParsers = m.module.parsers;
and it works!

Re: [beagleboard] Re: Help Needed : Custom built debian image
Thanks Robert,
Will disable this in my next build and will check the size of the image.
Hopefully it won't be a big difference.

Hi Robert,
As already mentioned in the previous comment, I am not setting lang

Its automatically coming as en_IN
Weird, i should setup another vm, with a different locale and see if i
can fix that..
If i disable the line that is removing extra locales, how much more
space
will be required.
I'm not really sure anymore, been doing that for awhile.. So here's a
quick disable option:
https://github.com/beagleboard/image-builder/blob/master/beagleboard.org_image.sh#L418
rfs_strip_locales=${rfs_strip_locales:-enable}
Just comment it out to disable..

No, I have used binary package which seems to be built with config file at here https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux-am33x/config I've managed to compile uio_pruss as module separately however, even if I load this module uio_pruss.ko, I cannot get /dev/uioX or /sys/class/uio/*.
