With the current shortage and future price increase, it may be worth 
investing in BeagleBone protection again ;-)

This 'surge protector' cape you mention already exists!

Shameless plug:

Have a look at the BeBoPr series of boards and the current BeBoPr++. The 
analogue inputs are designed to handle shorts against a 12 Volt supply. 
Besides the over voltage protection you also get an extra (better) ADC, 
protected digital inputs, both TTL and high current outputs, a 12-24 
Volt to 5 Volt step down converter, I2C level shifter, etc. Oh, and you 
can also use it to control some stepper motors, e.g. to build a 3D 
printer, or a laser cutter, or a router, or something I haven't thought 
of yet. There's a picture and manual available for download via this 
link: https://github.com/modmaker/BeBoPr-plus-plus.

Re: [beagleboard] Kernel 3.14, I cannot find uio_pruss module.

[Sungjin Chun]

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/*.

I also changed my dtb in boot/dtbs directory (which arch linux uses) like
this

https://github.com/chunsj/nxctrl/blob/master/am335x-boneblack-3.14-mine.dts

where I added pruss section and changed status from disabled to okay.

[beagleboard] Re: BBB debian problems with USB

[dickelbeck]

Toni,

lsusb needs to see a directory in existence, else it goes quietly into the 
night.  I devised this script fragment to solve the problem.  
Run it early in one of your boot scripts, it can be added as part of en 
existing script.

for i in /sys/bus/usb/devices/usb*; do
echo $i
if [ -d $i ]; then
mm=`cat $i/dev`

major=$(echo "$mm" | sed 's/:.*//')
minor=$(echo "$mm" | sed 's/.*://')

busnum=$(printf "%03d" `cat $i/busnum`)
devnum=$(printf "%03d" `cat $i/devnum`)

mkdir -p /dev/bus/usb/$busnum
mknod /dev/bus/usb/$busnum/$devnum c $major $minor
fi
done


I think /dev/bus/usb is a directory that must exist for lsusb to happy.

any change with the v3.13.x kernel?

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh --beta-kernel
(reboot)

To restore 3.8:
cd /opt/scripts/tools/
sudo ./update_kernel.sh

[beagleboard] Debian Boot Messages Regarding Cape and a USB Hub Question

[macarr]

Hi All,

I think this might be a Robert Nelson Debian question but here goes

I'm running Debain version- Linux beaglebone 3.8.13-bone41 #1 SMP Tue Mar 4 
22:51:47 UTC 2014 armv7l. I have a serial port connected to watch the boot 
messages. I've noticed the following reported conflict when the kernel 
starts:

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

[1.207087] pinctrl-single 44e10800.pinmux: could not request pin 21 on 
device pinctrl-single

I don't know why I have the conflict on slot #6. Is the kernel expecting an 
HDMI device to be plugged in and if not report the result as a conflict?

I am also trying to use a powered USB hub. I've tried several with no joy. 
Here are the messages I'm getting:

First the powered UDB Hub isn't reported by lsusb

When I plug a USB keyboard into the external hub dmesg reports:

I don't know if it's hardware or software but I know I get the same results 
with several different USB hubs using a separate 5VDC supply. I've also 
tried an unpowered USB hub. No change.
Has anyone seen this? I've tried two different BBB. One was a rev 'B' 
version the other was an A5A version.

Well, it depends a lot on specifically what you want to do.  I have done a 
couple projects on the older Beagle Board,
and recently, one on the Bone Black.  For that one I used Glade to develop 
a GUI page, and then built the back
end with c that controls the hardware.  I used mmap to access the GPIO pins.

This has worked very well for me.

I haven't changed the content of that, So that will be having some default

networking.service as disabled. Will there be any consequences for having

Re: [beagleboard] Re: Developing for BeagleBone Black

[Gunjan Gupta]

I guess that comes bundled with debian by default. I have build some custom 
debian images using scripts provided by Robert and have noticed them 
getting included in the image.

Hi Robert,

Thanks for reminding me of systemd-analyze. Completely forgot about that.

Here is the output of the command

So it looks like networking.service is eating up all the time. Is it safe 
to disable this service with connman installed?

Hi,

You have used both the 5V power source and the mini usb cable. I guess 
thats why your board got fried up. Use only one of them for the next time.

I see the same thing. Symantec Signature is: WS.Reputation.1

I still had a previous version (from September 2013) of the file in my

Two things come to mind...  openssh-server key regeneration: (this
only occurs on the first boot)

root@beaglebone:~# rm -rf /etc/ssh/ssh_host_*
root@beaglebone:~# time dpkg-reconfigure openssh-server
Creating SSH2 RSA key; this may take some time ...
Creating SSH2 DSA key; this may take some time ...
Creating SSH2 ECDSA key; this may take some time ...
[ ok ] Restarting ssh (via systemctl): ssh.service.

real 0m13.760s
user 0m10.813s
sys 0m0.893s

but the other 50 some seconds..

So factory image: (wicd)
http://paste.debian.net/92793/

btw, systemd provides a nice tool to help debug this:

systemd-analyze

Using:
systemd-analyze blame

http://paste.debian.net/92798/

Hi Santosh,

If you are not belonging to a company and ordering it for your personal

was not seeing any progress when ordering from element14. Crazypi delivered 
it for me in 2 days.

What is the md5sum on the .exe? These drivers are signed by a company
in China as I don't have the tools to sign them myself. You can go
back to the drivers in the 1.0 release to get the unsigned versions I
created. I also provided the makefiles so you can build them using the
Microsoft binaries.

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

[viraniac]

Hi Robert,

Here is the pastebin of one of my custom built image's dmesg output.
http://paste.debian.net/92787/

As you can see in the log, there is no log from around 6 second in the boot 
process to 70 second of the boot process. For this time, the BBB just 
doesn't respond and after that it resumes booting. 

For this image I have removed connman, wicd at image creation time but have 
added them back after booting for the first time. The image still takes 
around a minute to boot. http://paste.debian.net/92791/ is the pastebin url 
with connman

Please help me in optimizing boot timing.

Re: [beagleboard] Re: Availability - how come nobody has any BeagleBone Black to sell?

[Gerald Coley]

That is 222 RMA's received and 145,000 boards shipped. Not all RMAs were
bad. A lot of them were just reflashes.

Wow, that would be 2.8 boards :)  did you mean 0.002 aka 0.2%?  This
would mean that you fixed nearly 300 RMA'd boards, which is both

Correction. I was a bit off on that RMA rate. It is actually 0.15%. 145,000

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..

[beagleboard] Re: How to use UART Serial Port Using BoneScript Library

[Mark A. Yoder]

It almost works out of the box. I changed baudrate to 9600 for my GPS and 
data shows up.  However I wanted one line of data at a time so I added:

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!

--Mark

p.s.  How do I do a pull request on bonescript?

[beagleboard] Cannot use Ralink RT2870 Wi-Fi USB Dongle on Android, BeagleBoneBlack.

[take1108]

Hi, I'm using BBB and I tried to install and use Android 4.2.2 with USB 
Wi-Fi dongle, but my dongle is not working under Android.
My dongle's maker is Logitec and its chip is Ralink RT2870.

For this Challenge, I followed these 3 sites.
http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide
http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_PortingGuide
http://nelenkov.blogspot.jp/2013/07/building-wireless-android-device.html

First, I followed the Developer Guide and I have done from section 1.2 
(Host PC Setup) to section 1.6 (Flashing to SD). Then My BBB undrer Android 
was working , but I cannot use USB Wi-Fi dongle, of cause.

Second, I followed the WLAN section of Porting Guide and nelencov's past 
work, and I recognized that I should change some setting files.
I show the list of my changing as below.

- menuconfig
-- Ralink Support and rt2x00usb Device Support were choosed.
--- then, cfg80211.ko, mac80211.ko, rt2x00lib.ko, rt2x00usb.ko,

Re: [beagleboard] AIN max voltage exceeded

[Gerald Coley]

Yes. You will need to replace the most expensive part on the board. The
processor.

The "partition" shown over the usb interface is defined in:

/opt/scripts/boot/am335x_evm.sh

https://github.com/RobertCNelson/boot-scripts/blob/master/boot/am335x_evm.sh#L71

"file=${gadget_partition}"

So if you want to pass a usb flash drive, use: file=/dev/sda1

[beagleboard] Re: USB mass storage on BeagleBone shown as mass storage under Windows

[mickeyf]

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.

[beagleboard] use BB-xM to send raw ethernet packet

[user48625]

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   
 , 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.

Thanks!

[beagleboard] Frame rate / sound quality extremely slow

[Padawan]

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)? 
Please let me know what logs and settings would be helpful.  

-Padawan

Re: [beagleboard] Re: UART4 stopped working: did not get pins for uart4 error: -19

[pollock . phil]

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
  44e07000-44e07fff : 44e07000.gpio
44e09000-44e0afff : /ocp/serial@44e09000
  44e09000-44e0afff : omap_uart
44e0b000-44e0bfff : /ocp/i2c@44e0b000
  44e0b000-44e0bfff : /ocp/i2c@44e0b000
 ??@ ??F ? e10623 : @
44e10628-44e1062b : /ocp/usb@4740
44e10800-44e10a37 : /pinmux@44e10800
  44e10800-44e10a37 : pinctrl-single

...

On Angstrom (where everything is working) I see:

root@beaglebone:/proc# more iomem
44e07000-44e07fff : /ocp/gpio@44e07000
  44e07000-44e07fff : 44e07000.gpio
44e09000-44e0afff : /ocp/serial@44e09000
  44e09000-44e0afff : omap_uart
44e0b000-44e0bfff : /ocp/i2c@44e0b000
  44e0b000-44e0bfff : /ocp/i2c@44e0b000
44e10620-44e10623 : 4740.usb
44e10628-44e1062b : /ocp/usb@4740
44e10800-44e10a37 : /pinmux@44e10800
  44e10800-44e10a37 : pinctrl-single

...

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

Thanks,
Phil

As you can see I am getting warning messages about locales. I haven't 
manually set the LANG to en_IN. I guess I have to include all the locales 
to shut this message down as I am building this image for one of my client 
and not for myself.

The pastebin for this image's dpkg --list is here

[beagleboard] Frame rate / sound quality is refreshing slowly, strategies to fix?

[Padawan]

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.

[beagleboard] USB mass storage on BeagleBone shown as mass storage under Windows

[ibinsdahanse]

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?
 
Thx a lot
MG

[beagleboard] Accommodating Arduino Shields: Updated Pinmux

[barthels]

Dear Community,

we would like to share with you our recent discussions about minor changes 
in the Shield I/O pin mapping, which further improve Arduino compatibility.

We have also carefully checked the mapping specified by the 
“userspace-arduino” project on 
http://beagleboard.org/project/userspace-arduino/, but we think in 
comparison to our proposed mapping 
(PDF)
 
there is less flexibility given. Feel free to tell us your suggestions.

Best Regards,

Daniel Barthels

Re: [beagleboard] Re: Beaglebone Black USB Host turns off

[Tomas Mandys]

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.

Tomas

[beagleboard] AIN max voltage exceeded

[lubotomie11]

Hi,

I did the big mistake... 5V on an AIN pin. For those who always wondered 
what happens, nothing truly exciting : the board just suddently shut down, 
and can't be turned on anymore.

Is there a way to fix this (by replacing a part for example) ?

Thanks,
Lucien

[beagleboard] AIN max voltage exceeded

[lubotomie11]

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) ?

Thank you,

[beagleboard] python gui?

[Eric Palmer]

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.

If you search google groups for "QT5.1.1 running on BeagleBoneBlack", you
will see I explained how to make this work back on Dec 15. Some of the
instructions are now obsolete because Robert Nelson applied these patches to
his kernel and also added SGX scripts, but the configuration and building of
QT will still be the same. I did this on V3.12, but I believe this should
now work on V3.8.

John
