Where did you get this android source from? Generally, there should be 
instructions accompanying the source for compiling.

If you are using the latest TI DevKit android sources, the build

Not going to happen. A few months ago I asked Gerald to look at making a
module version of BBB for a while and he is dead set against it. I always
thought it would be better to have a module and a range of of base boards
rather than capes. It would be quite simple to create a custom base board
with all the features you need, but Gerald didn¹t agree. In the end, he has
been very successful at designing products that have been very successful,
so I deferred to his expertise. Remember, Gerald is highly focused on the
hobbyist and doesn¹t want his boards to be sucked up by companies for their
production.

Re: [beagleboard] What went wrong

[nashid . mujahid]

Yes you're correct, but I used this port as well due to attempting to 
figure out why my wireless dongle for keybrd and mouse wasn't working any 
longer when it was connected to USB Host connection. When the dongle didn't 
work on USB host I then connected it to the USB hub getting the same 
result. This is when I attempted connecting the USB client connection to 
the hub and the Hub to the USB Host connect resulting in the arching 
effect. My thought is it broke my board.

[beagleboard] Expanding Debian mSD Card Partition

[Carl Schaefer]

I have Angstrom loaded on the eMMC but just downloaded a Debian image to a 
mSD card.  I successfully booted to Debian on the mSD card and was able to 
get into LXDE with no issues.  Before I did that, I upgraded all Debian 
packages in the command line through PuTTY on my PC over a USB line.

When I open file manager in LXDE, I notice two mounted drives:  Angstrom 
(the eMMC) and Beaglebone (Debian on the mSD card).  The mSD card is 16 GB 
but it shows that there is only 15.3 MB of free space.  The Angstrom drive 
shows 558.7 MB free.  How do I increase the partition size of the mSD card? 
 Can I do this in the LXDE environment logged in as root?  Or, do I need to 
do this via a command line interface?

[beagleboard] Re: Developing for BeagleBone Black

[michael . duffy]

Using Python -- along with the Adafruit BBIO Python library -- works quite 
well, and gives you all the development power of Python and associated 
native and third party libraries.  Lighter weight than Java or C++, much 
higher level than C.  I can't speak to Lua (no experience with it).

Easy to get things running, and seems to run well under Angstrom.

Re: [beagleboard] Dusting off 4 year old C4, boot issues

[djbbrisson]

Since my SD card was already booting successfully, I just went ahead and 
cleared the nand.  Mission accomplished, BeagleBoard boots the SD card when 
I give it power.

Thank you for the helpful advice.

[beagleboard] Ethernet not available with debian/ubuntu 2014-02-16 but available with Angstrom

[Francesco Montorsi]

Hi all,

I have two BeagleBone boards. Both are Rev A6A.

I have been using the boards with an old Ubuntu image (sorry, can't 
remember the version!!) till a few time ago; the Ethernet interface was 
working fine with Ubuntu at that time.

Then I have recently upgraded my SD card with 
"ubuntu-13.10-console-armhf-2014-02-16", following the instructions at 
  http://elinux.org/BeagleBoardUbuntu
the problem is that after the upgrade the Ethernet PHY is not detected 
anymore! 
A not very clear message at boot, related to Ethernet, is:
 libphy: PHY 4a101000.mdio:01 not found
Then, when I log in, using "ifconfig" I see no "eth0" device and the 
attempt to bring it up fails with something like "eth0 network interface 
not available".

At first I thought it was an hardware problem, but both boards presented 
the same issue. Moreover, to try to "rollback" I've been flashing on the SD 
card several older versions of Ubuntu & Debian, without success. Finally, I 
tried "Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.20" 
and it works: eth0 is detected and working.

Do you have any hint to help me understand the problem? I would really like 
to use debian / ubuntu on my beaglebones but I cannot use ethernet so far...

Thank you very much for any help!

Re: [beagleboard] Re: why update eMMC?

[Brad Hopper]

I'm thinking to use Charles S's MachineKit LinuxCNC image, which occupies 
4G and would like to run it from the eMMC rather than an SD card, with card 
dedicated to machine/print job files.

I was a little annoyed (but happy) to hear that there's a 4G revD board 
shipping soon, at least according to Sparkfun here:

https://www.sparkfun.com/products/12857

Is this true? If so, is it a clone or original BBB revision? Why not 
mention plans for the new rev in either this or the "out of Stock" thread?

Anyway, happy it's coming if true.

Re: [beagleboard] I powered the analog input of my BeagleBone Black with more than 1.8V

[A M Kent]

I think the same is the case with mine. Here's what I experienced. 
See this forum entry. 

would the RMA link you've provided apply to my situation as well?

The micro USB port is not for a hub. It is for a PC.  Maybe you might want
to take a look at the manual.

[beagleboard] What went wrong

[A M Kent]

I've recently purchased the BBB and over the weekend I went through setting 
it up. I have to say I'm thoroughly impressed with the setup and the size. 
I followed the supplied instructions of connecting the device to my 
computer using the USB cable connecting it from the micro USB port to a 
port on my laptop, installing the necessary files to communicate with the 
device. My
issue occurred when I connected the BB in the following manner.

1. From micro HDMI port to HDMI port on monitor.
2. Connected the 5V power source into the BB
3. Connected a USB cable from the USB jack on the BB to my 4 port powered
USB hub.
4. Connected the micro USB cable into the 4 port hub.
5. Inserted wireless keybrd/mouse dongle into the 4 port hub.

When I applied power to the BB within 1 minute of doing so I hear a faint 
high pitch tone and shortly thereafter I see a spark coming from the board. 
Based on the setup described what could have gone wrong?

Yeah, I got tired of waiting so I documented by setup as well as

[beagleboard] Re: CONFIG_WATCHDOG_NOWAYOUT => How ?

[AndrewTaneGlen]

To get the hardware watchdog working (on Debian) I just installed the 
watchdog package (sudo apt-get install watchdog), then set the correct 
device in the config file: in '/etc/watchdog.conf' set 'watchdog-device = 
/dev/watchdog'

I'm fairly certain that's all I needed to do.

[beagleboard] Re: i want to build a internet kiosk

[Piotr Murawski]

Hello Navot, 

There are several options regarding OS and configurations, there are pros 
and cons for any of them. I'll describe my experience with Ubuntu and 
browsers. 

1) I'm creating somehow "operator desktop", which is not much different 
then a kiosk application. 
2) The biggest issue is the browser: 
- Ice Weasel (Firefox like), heavy, clunky, generally always makes troubles 
for my pages. I gave up this guy quite quickly.  
- Chromium, fast but heavy, starts a bit long but it is smooth. It has a 
kiosk mode, but sometimes displays nasty po-pups (like info about no 
closing last time), this can be fixed by cleaning up the profile on 
start-up.  
- Midori, "The Third" browser in my opinion, positive experience. Not that 
fast in vector graphics as Chromium. 
- DWB, regarding performance, same as Midori, but with extremely minimalist 
UI. Interesting project however, I'm afraid of support. 
- There are few others I have looked at, like :luab or something like 
this.  
Except Ice Weasel, all other browsers bases on Web-Kit, so they are somehow 
similar standard implementations. 
3) I didn't start UI desktop, just Xorg and a very simple window manager 
"Matchbox Window Manager". DWB even do not require a manager. If you plan 
to build a kiosk, try do the same and do not start a UI desktop, it just 
wastes memory in this case.
4) Do you plan to use touch screen? Generally quite painful, there are 
several discussions about this. I had to fix the driver for my touch screen 
hardware.   

That's it. 

Good Luck. 
Piotr.

Thanks Denis,
you are right.

I've been mixing configuration register offsets and their names. But I've 
managed finally to get it right.

It would help if the conf_* registers were predefined in the header and 
cape DTS files would use that defines.

I haven't had a chance to try it out as I don't have a device easy to

example at: http://jsfiddle.net/jkridner/AjnJs/

BoneScript simply uses this same library, so using BoneScript avoids 
needing to install it.
 

>

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] Which Real Time Operating Systems Can I run on Beagle Bone Black?

[Charles Steinkuehler]

In my images, the ARM core is running motion and trajectory planning in
a 1 ms (configurable) loop, using the Xenomai real-time patches.  If you
don't have something like Xenomai or PREEMPT_RT patched into the stock
Linux kernel, the 1 mS loops do not execute at the proper time.

The PRUs are used to generate step/direction pulses at (potentially)
high speed, running simple code in a short loop (typically 1-10 uS),
which is not possible on the ARM.  Even with Xenomai, IRQ latency is on
the order of 20-60 uS for the ARM, so it just can't run a task loop that
fast.  The PRUs don't have anything else to do, so they can happily make
step/dir pulses with good timings while the ARM core handles the
complicated not-so-time-critical stuff like motion planning, and the
non-real time stuff like a user interface.

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

[Gerald Coley]

Embest/Farnell is not supporting any SW. The use what is on the BeagleBone
Black.

These are the old clone boards from a while back and have old SW on them.
The new boards will have Debian, same as BBB.

Hi Miroslav,

You might want to double check what you are doing here. The clock control 
is on gpio1_27 as shown on page 3 of the schematic. Pin V17 is hardwired to 
the output enable of the 24.576 MHz oscillator. It can turn the oscillator 
on or off. This output must be turned on to use the HDMI audio.

Gpio3_21 is connected to the oscillator output and used as a high speed 
clock input when the SOC is driving audio to the HDMI framer. If the 
oscillator output is disabled by gpio1_27 then the gpio3_21 pin can be used 
for other functions.

Farnell owns Embest. But, it is not branded as Farnell

They are still using the 2G eMMC.

RE: [beagleboard] i want to build a internet kiosk

Hi Navot;

 

If you go to this site: https://specialcomp.com/beaglebone/index.htm

 

You can buy just the Atrix laptop and cables. I have an 8GB image of Ubuntu 
with a couple of different GUIs

up and running.

 

Works great and Ubuntu has support for just about anything.

[beagleboard] WiFi dongles slow BBB to nearly a halt

[jason . fehr]

Hi, I've just installed the newest official Debian Image (3-27 flashing) 
into eMMC and when attempting to use a WiFi dongle the board slow down to 
unusable speeds. Just typing through ssh can take 8-10 seconds for the 
characters to appear, but they will appear in groups so they are being 
cached somewhere then when the board gets around to it they are displayed. 
I've tried two separate dongles which are:

http://www.adafruit.com/products/814
http://www.newark.com/element14/wipi/module-wifi-usb-for-raspberry/dp/07W8938

and both have the same issues.

The install is pretty much non-modified. All I have done since setting it 
up has been to change the default password, setup my own user account, and 
uncomment the following four lines in /etc/networking/interfaces

auto wlan 0
iface wlan 0 inet dhcp
wpa-ssid "essid"
wpa-psk "password"

of course I changed the ssid and password to those for my network. The 
board does receive a connection to the router and I can ssh into it through 
the wifi, but about a minute after booting it slows right down.

I have attempted this through both a USB connection to my computer as well 
as with a 5V 2A power supply.

Any help would be appreciated.

J

If you have setup remote terminal access (see derek malloy's video tutorial 
on how to do this), then this should be easy.

Copy the executable file from Debug folder of the Eclipse project, see the 
project workspace on the right, expand the Debug folder then copy the file 
to the BBB root folder, in the Remote system explorer tab.

Ensure file is executable, from terminal execute the program by entering 
./program name in a terminal.

[beagleboard] BeagleBone Black is not booting up

[madhukar45]

I was booting my BBB using eMMC. After that i powered down BBB and inserted 
a blank 2GB uSD card. It stopped to boot. I removed the 2GB uSD card but it 
is still not booting. I even rewrote the eMMC as described 
in http://derekmolloy.ie/write-a-new-image-to-the-beaglebone-black/ but it 
still not booting up. eMMC however gets written as all the LED's flash 
after the completion.
Please Help.

[beagleboard] BBB HDMI

[ec123ec]

Hi,

I'm brand new to Beagle, and I know there is a lot on BBB & HDMI issues, 
but I have not seen anything like this. I plugged in my BBB for the first 
time today.  I'm using a brand new, good quality HDMI cable and a 5V ps @ 
1.5A.  I had BBB running with my Visio on HDMI 2 for about an hour.  Then, 
all the sudden the video signal drops.  I move my cable box to HDMI 2 and 
there is video, so the TV HDMI is OK.  I move BBB to HDMI 3 and same 
problem.  I did get it to come back after cycling power on the TV and BBB, 
but it quit after a few seconds.  That only worked once too.  Are there TV 
or BBB settings that will make the HDMI more stable?

Thanks!

[beagleboard] BBB is not booting up

[madhukar45]

I was working with BBB with angstrom distribution booting from eMMC. Then i 
powered down the board and inserted a blank 2GB uSD and then when all my 
problems started. I as not able to get the system. Then i tried removing 
the uSD and booting but things did not work out. I rewrite the flash as 
shown in http://derekmolloy.ie/write-a-new-image-to-the-beaglebone-black/ 
and the process is getting completed but BBB is not booting up. Please help 
me...

Re: [beagleboard] Re: Driving DC Motor with L298 and BeagleBoard

[digish . pandya]

Hi new-be here Can you please post schematics if you could successfully 
control two motors using L298 with beaglebone black i am confused with how 
to convert levels
from GPIO are you using NA for it ?

thanks

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

[Craig P]

I see Embest Technology Co., Ltd is a Premier Farnell Company. I assume 
this means Farnell/Element14/Newark will now only be selling Embest clones 
from now on?

Yes and no. The solution was worse than the problem. Updating to the 
development kernel as mentioned above resulted in better support for Wifi 
but an unstable LXDE environment. At this point I just don't rely on Wifi.

I'm still running into some annoying root/debian user permissions problems. 
First, I have to switch to the root user in order to run a script I wrote 
to share the host computer's Internet connection. Second, when I push to

okay, but I don't know how to go about fixing whatever is causing the error.

[beagleboard] Help Needed: Regd Custom X environment

[viraniac]

Hi,

I need to build a custom BBB image which should start a java program as the 
GUI. I am already aware about customizing the BBB Debian image using the 
image builder scripts.

I have built custom image with no LXDE or lightdm. I have added xinit 
package and the Oracle JDK to the image. I tried various combinations in my 
xinitrc file but am not able to get the java program started. Please help 
me on getting the program started when running startx command.

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

[viraniac]

Hi lisarden,

I am tried to make the bare minimum image but that takes too long to boot 
while compared to the image supplied by the Beagleboard community. Also if 
you see all the questions that I posted were about customizing the image 
using the image-builder script. So its not that I am going from end to the 
beginning. I am at the extreme begininning of creating a customized OS. 

Let me tell you my requirement.

I need a OS that shows a splash screen at boot. Once the OS is booted it 
will run a Java program instead of lxde to show the UI.

I had no luck with splash till now though I know that I have to use 
psplash. Also I tried changing the /etc/lightdm/lightdm.conf and 
/usr/share/xsession/LXDE.desktop file to invoke the java program but had no 
luck with it. I tried disabling the lightdm service by removing the 
/etc/rc5.d/lightdm symlink but still lightdm starts and shows LXDE at boot 
up.

Please Robert and lisarden, help me with this so that I can complete the 
image.

PS: I have customized the target/chroot/beagleboard.org.sh file to add the 
oracle_jdk into the image and to remove chromium from the image. the rest 
of the packages are left as it is.

Saturday April 12th We are presenting our second teaching of
Getting started with ROS on a Beagle Bone Black (BBB)

This is a Full Day Hand on Teaching Seminar.  Location  Mountain View 
California.

You will leave with a working motor controller fully controlled via ROS and 
learn step by step the process for wiring ROS into a BBB. 
You receive about $18 of hardware including a SDcard and a 2 Channel Motor 
Controller board.

Details at ROS-Training 
http://ros-training.com/courses/control/beagle-bone-black/

Tickets are available at EventBrite 
https://www.eventbrite.com/e/ros-training-beagle-bone-black-with-ros-tickets-10792427441

[beagleboard] Re: Beaglebone Black USB Host turns off

[hobbes4145]

Hi,

I have been following this USB thread for a while and wanted to add my 2 
cents. I have a related but "opposite" problem. My hot plug works but my 
cold plugs does not. 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. Only started shipping from March 2014 onwards. I 
noticed a capacitor discrete mounted near the USB port. Is this a Rev B 
hack?

*What I am trying to solve*

I would like to have the USB devices come online upon power up without 
having to observe the (1) BBB on first (2) plug in the USB Hub + devices 
sequence. 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?

Best, Mike

Re: [beagleboard] Re: Angstrom passwords

[Carl Schaefer]

I had the same login issue when I upgraded Angstrom (i.e., the "MPD" and 
"XUSER" login names).  Thanks, Wilfredo, for the help.  This is what worked 
for me:


   - Before you do anything, upgrade your packages:  "opkg upgrade" (I did 
   not have to run "opkg update" first for this to work for me.  However, I 
   think it makes sense to update the package list before upgrading.)
   - The, run the command: "opkg install --force-reinstall 
   angstrom-gdm-autologin-hack"
   - Reboot

With wireless mouse/keyboard installed and monitor hooked up, the BBB boots 
into the Angstrom GUI as root.

Re: [beagleboard] HDMI to VGA, on boot the board displays its logo, but then ceases to display anything. Please Help

[bert . elema]

Hay

I think your problem is the 5Volt suply of the HDMI to VGA converter. 
Normally it should get 5V from the HDMI plug but as I understood the 
Beagleboard does not supply the 5 Volt at pin 18 of the plug, therefore you 
should have a HDMI converter with his own power supply.

You have a really old verison of u-boot installed in "nand" that's
getting in the way.

See for hints:

http://elinux.org/BeagleBoardUbuntu#Upgrade_X-loader_and_U-boot

With the C4's i usually just clear the nand and trust that the microSD
has the correct u-boot vs just flashing nand.

[beagleboard] Dusting off 4 year old C4, boot issues

[djbbrisson]

My BeagleBoard has been collecting dust for a few years and recently had a 
need to revive it.  I took it out of the static bag and got to work.

To make a long story short I have re-flashed the NAND.
Source:  http://elinux.org/Beagleboard:BeagleBoard#Rev_C4

I have loaded Debian 7 via a netinstall image on an 8GB SD Card.  This is 
ultimately what I want to use on the BB C4.

I have set SD Card to boot by default using 
set bootcmd 'mmc init ; fatload mmc 0:1 0x8000 uimage ; bootm' ; saveenv
source:  http://elinux.org/BeagleBoard_Community#MMC.2FSD_boot

Unfortunately, this doesn't work, I get "Wrong Image Format for bootm 
command" & "ERROR: can't get kernel image!" messages on boot.
See http://pastebin.com/XizcZUCB for complete boot capture.

After the above, if I press reset while holding the User button, the SD 
Card boots just fine.

After all that, here is my question.

What do I need to do to make the SD Card the default boot up device?

Thanks!
Don

Re: [beagleboard] BBB as a router w/ firewall capabilities

There should be a cape to have these 2 NICS, thus using Xenomai -or

tests on eMMC with latency tests gave an average of 14 µS

Inspired by this post I checked out de.farnell.com for the BBB: now
the state is "product no longer available". Seems like Farnell gave up
to try to sell BBBs :-(



They've started selling the 'Element14' branded version instead:
Ordercode: 2401441
817 in stock for next day delivery...

Re: [beagleboard] Re: BBB & NRF24L01+

[Gaetan RUAULT]

Hi,

I want to make communication between an arduino and a bbb.  Both have an
nrf24l01+ module.

I have plug a nrf24  to  the spi0 on my beaglebone.
and enabled SPI via  http://elinux.org/BeagleBone_Black_Enable_SPIDEV



I use then node-nrf module  and this script :


var NRF24 = require('nrf'),
spiDev = "/dev/spidev1.0",
cePin = 16, irqPin = 19;
pipes = [0xF0F0F0F0E1, 0xF0F0F0F0D2],
role = 'ping';


var nrf = NRF24.connect(spiDev, cePin, irqPin);
//nrf._debug = true;
nrf.channel(0x4c).transmitPower('PA_MAX').dataRate('1Mbps').crcBytes(2).autoRetransmit({count:15,
delay:4000}).begin(function () {
nrf.printDetails();
if (role === 'ping') {
console.log("PING out");
var tx = nrf.openPipe('tx', pipes[0]),
rx = nrf.openPipe('rx', pipes[1]);
rx.pipe(tx);
} else {
console.log("PONG back");
var rx = nrf.openPipe('rx', pipes[0]),
tx = nrf.openPipe('tx', pipes[1]);
 rx.pipe(tx);
}
});



but nothing append on my BBB.
the call of nrf.printDetails()  print ll default values and not my
configuration
result.(.channel(0x4c).transmitPower('PA_MAX').dataRate('1Mbps').crcBytes(2));

cePin is plug on P9_15  and irqPin on P9_16

thanks for your help.
