Re: [beagleboard] Read current register values in BBB during OS running

[Giuseppe Iellamo]

If they are memory mapped register you can also use a tool like devmem2 or 
mmap yourself the register to access them directly.

This is not real linux style and a bit dangerous and certainly not portable 
at all-- but you can do it

[beagleboard] Re: what's the BBB boot procedure?

[dlewin555]

Indeed, I share your wondering Rusty. 
Just a simple note : your link to the (greaaat) Sabayon has a typo, it 
should be : 

https://wiki.sabayon.org/index.php?title=Hitchhikers_Guide_to_the_BeagleBone_(and_ARMv7a)

I didn't see these links in the eelinux wikis (official or Community) : I 
think it really worth a place there.

  quick question to the list, that's probably been spending more time
on this than i have lately -- i'm assuming that, by now, u-boot for
the BBB is pretty much a solved problem and is fairly stable, with
most of the enhancements coming in the form of updated device trees
and newer uEnv.txt files, yes?

  i'm asking as i want to go back shortly and update a lot of my wiki
pages related to the BBB, and i would *imagine* that pages related to
the base u-boot code won't really have to change much, although i'm
happy with being proven wrong.

[beagleboard] Flashing Compiled Kernel

[godsfshrmn]

I have compiled the latest debian kernel using instructions I found on 
another post:

git clone git://github.com/RobertCNelson/linux-dev.git
cd linux-dev/
git checkout origin/am33x-v3.8 -b tmp
./build_kernel.sh

The build is complete. I can't figure out how or which file I need to use 
to flash it to the eMMC. If I try to run ./tools/install_kernel.sh it tells 
me "Please update MMC variable in system.sh", which I did: 
"MMC=/dev/mmcblk1"
mmcblk1 corresponds to my emmc. Any thoughts?

[beagleboard] Control hardware from webserver

[jdswensen]

OS Image: Ubuntu Precise 12.04.3 LTS

I'm attempting to control LEDs from a webpage (and eventually other 
hardware from the device tree overlay).  I've written a C program to toggle 
the onboard LED based on the arguments passed to it. This only works if you 
run it as root however.  I've also installed lighttpd and have a php page 
running with a link to toggle the LED based on button press.  To work 
around running as root, I added a setuid(0) to the C program and changed 
the ownership of the gcc output binary to root, then made the binary 
readable and executable by any user.  The result is that the php page can 
control the LED, but I'm uncertain of how safe this set up is.

Is there a better (safer) way for me to be controlling hardware from a 
webpage with C?  If not, what are my other options?

Let me know if I can provide you with any additional details.

Thanks,
Jake

[beagleboard] OwnCloud File Server for home network

[Gab riel]

Hello,

i have this idea in my head

I want to have a small File Server for my home network and was thinking 
that OwnCloud could do the job (Contacts, Calender, Files)

What should it do?

-Sync Contacts, Calender to Android and Mac
-Store Files (mostly video, music, and some documents and maybe a backup 
from my laptop)

I was thinking about  the Beagleboard Black in combination with an external 
hard drive and an ethernet connection to my network.

following questions have occured:

-Will it be powerful enough? (it doesn't need to be super fast)
-Which OS should i use? (which Linux? Ubuntu?)

Sorry for this easy question, maybe someone has some experience with 
Beagleboard and OwnCloud, or could provide me with alternativs, links etc.

Thank you for your answers and your help,
BR Gabriel
And a second sorry for my English, it's not my native language.

[beagleboard] up all night.. fdisk questions

[Ron Morgan]

I got a shinny new bbb today.. havent stopped playing with for the last 9 
hours.. so im kind of tired. 

I have a BBB runing debian 7.2 from a 8GB micro sd. 

all is working fine with debian, its running headless at the moment which 
is fine with me. when I installed the debian image to the sd card, there 
was some space "at the end of the card" that I wanted to reclame. I did a 
little poking around and some thing is a ... odd. I could use some input. i 
am not a total noob but im by no means an expert with linux. 

I ran df -h to find what was used and where


that looks fine.. then I ran fdisk -l to see what i could see. I am not 
quite sure how to interprate this




1 how does /dev/mmcblkboot0 and mmcblkboot1 not cotain a valid partition 
table? what does that mean exactly? how does this boot without a valid 
partition?
2 why or how, does the sd card boot start at 2048? and use a fat12? I have 
never even heard of a fat 12 file system..
3 given the boot is starting where is it, and the 2nd primary is about 
3.6gb? I have a bout 3.7ish GB to make a partition out of? I think 8gb sd 
is relly 7.39ish?

please double check my math.

how big should I make swap? I used to double the ram back in the when you 
always had a swap disk.. but most boxes today have so much ram there is no 
need and it has been like a million years from the last time I have worked 
with something like .. this .. small... or with something that has this 
amout of resoruces:)

thanks guys.. im going to bed, its 2 am.

[beagleboard] Re: OneWire (w1) Stopped Detecting Sensors

[Andrew Goins]

Yea that was my first thought too. I've tried sensors that were working
fine. I wonder if I inadvertently messed up something on the software side.
I just don't know where to check. The only information I have is the error
that shows the device tree is having trouble from dmesg log above.

i was successfull to connect to the beaglebone with ssh just using the ip 
address.

the i tried to setup a automatic ntp update and now there no way to connect 
to the bbb by sss - not by wifi and not by the usb cable.

any idea whats wrong?

i removed the ntp on my bbb and also removed the dropbear rsa host key file 
and started dropbear again but still no way to ssh.

[beagleboard] Re: BeagleBone Black doesn't boot from microSD card

[jcmcanuck123]

I know I'm replying to an old thread but I had the same problem but found 
something others might have been overlooking.  I spent a lot of time 
thinking that I screwed something up in my boot sequence because I never 
could get the beaglebone to load from the microsd.  I tried multiple OSes 
and messing with the uEnv file and still couldn't get it to work.  I 
finally realized that somehow one of the connector pins on the beaglebone's 
microsd port was slightly off of the microsd.  This must have caused the 
beaglebone to think there was no microsd and it just loaded what was in the 
emmc.

 Hey guys,

 As promised. Ubuntu 12.04 BBB image for the Chipsee 7” 1024x600 LCD 
 touchscreen.

 Grab it here:
 http://www.fileswap.com/dl/sdFGPZoIw6/

 You should find yourself downloading 
 bbb-ubuntu-12.04-for-community.xz

 Just extract and write that to your SD card (4gb expected) with 
 something like:

 *cat bbb-ubuntu-12.04-for-community.xz | xz -d > /dev/sdX*

 Note it’s a raw sector dump NOT a tarball, so extract straight to your 
 SD card device. (eg.  /dev/sdx, NOT /dev/sdx1) 

 Also note this image doesn’t install or boot from MMC so make sure 
 you’ve got the SD card selected on the boot switch thing.

 Once the extract is complete, simply slap it into the BBB and boot.  It 
 should come up with the Chipsee splash screen but then
 boot into Ubuntu 12.04 after a while. 

 Hope this helps.

 l8r,
 Xris.

[beagleboard] I2C SDA spikes?

[keedog]

So I am using an I2C IR temperature sensor with the BBB. The device data 
sheet recommends performing an EEPROM dump, to store data on the mater. 
When I tell it to dump the device responds, nornally,  but then something 
pulls the SDA line up prematurely for about 5us and then and all the 
subsequent data retrievals are skewed, seen here by the skinny little pop 
in the upper left of the pic. 


this happens every time. any ideas? I have tried 10k and 1k pull ups and it 
still happens. Also, the clock runs consistently betw 3-5 khz slower that 
100khz. not sure what to make of that either.

[beagleboard] sleep mode and wake modes..

[Ron Morgan]

I have a BBB running headless debian 7.2 from sd card. 

I left it up and running last night, when I went to ssh into it this 
morning it was in a sleep mode or a suspend mode. I want the BBB to stay on 
all the time and not inter sleep mode at all. I have been searching and 
searching but really not much out there about debian on BBB. 

im not even sure if this is software ie debian.. or hardware ie something 
on the board or in the SOC? I have had the BBB for less than 36 hours so.. 
im sure there are great many things I dont know. 

any help or direction woud be great.

Thanks

[beagleboard] Frustrated trying to do basic things...

[Larry Klein]

I recently acquired a beagleBone Black board. Followed the simple 
directions to plug it into a USB port on my Win 8.1 PC and a new drive 
showed up. Yay!

EXCEPT that all files show up as size 0KB except for MLO and the boot 
image! And they really appear to be 0KB to my computer as i cannot open 
ANYTHING. Copied the whole contents to a local folder just in case, but 
also all 0KB.

OK, so I went to beaglebord.org and started looking at the getting started 
area. All good except that every file referred to like BONE_D64.exe or 
beaglebone-getting-started.zip
 is 
not there. I get a "link not found" error and, looking at the site, I see 
that the folders should be in the beagleboard.org/static folder tree, but 
the folders they would be in, Apps, or Drivers, do not exist!

I have done google searches to find other sources of these files but they 
all point back to this site!

Interestingly, most file in the beagleboard.org/static folder have a time 
stamp from last night at 7:20PM which leads me to think that someone may 
have been restoring files to the site from a backup and missed these 
folders?

But anyone have any ideas on the 0KB file size I see for the USB mounted 
disk?

thanks for your help...

[beagleboard] Beaglebone Black OLED 2864 SSD1306 Display how-to

[bbbusr]

I've got a beaglebone black and one of these 2864 oleds:

http://www.amazon.com/OLED-display-module-Gadgeteer-Compatible/dp/B00B0RH20S/ref=sr_sp-atf_title_1_3?ie=UTF8&qid=1391961553&sr=8-3&keywords=oled+2864

which uses the ssd1306, and I'm a bit new at interfacing with these 
displays.

I've done much searching already, seen related projects on github, adafruit 
site, etc.
https://github.com/adafruit/Adafruit_SSD1306
but I'm using Gentoo instead of Angstrom, and there are some slight recipe 
variations I don't fully grasp (unloading capes for instance).

Cluebat please...how would I best get from here to displaying values from 
(python) code?
Adafruit_BBIO and spidev are installed (although this may be i2c?).

Thanks

[beagleboard] Adding support for the BeagleBone White DVI-D with audio cape

[cde]

Hello,

The current 3.8 rcn linux-dev is missing the devicetree spec for this cape 
(http://elinux.org/Beagleboard:BeagleBone_DVI-D_with_Audio). This cape is 
based on the DVI-D rev A2 cape 
(http://elinux.org/CircuitCo/BeagleBone_DVI-D) combined with the audio rev 
A cape (http://elinux.org/CircuitCo:Audio_Cape_RevA). Typically, capemgr 
says at boot:

bone-capemgr bone_capemgr.8: slot #0: Requesting firmware 
'BB-BONE-DVID-02-00A1.dtbo' for board-name 'BeagleBone DVI-D WITH AUDIO 
CAPE', version '00A1'
bone-capemgr bone_capemgr.8: failed to load firmware 
'BB-BONE-DVID-02-00A1.dtbo'

The attached patch creates a new dts for this particular cape. It was 
tested as working for both DVI and audio out (ffmpeg -i file.mp3  -f alsa 
"default:EVM" -re -vol 50). However the HDMI cable has to be plugged in 
before the kernel boots, otherwise it says it defaults to 1024x768 (instead 
of the max resolution 1680x1050) and nothing is displayed. Does anyone have 
this problem with the DVI cape (with or without audio) has well? Also, is 
there a proper way to select the resolution? Typically, I'm looking to set 
1280x720@60 at boot. TILCDC_DEFAULT_MAX_BANDWIDTH in 
drivers/gpu/drm/tilcdc/tilcdc_drv.h seems to be the only way to force the 
resolution (also 
see 
https://github.com/beagleboard/meta-beagleboard/blob/master/common-bsp/recipes-kernel/linux/linux-mainline-3.8/hdmi/0009-tilcdc-1280x1024x60-bw-1920x1080x24-bw.patch)

[beagleboard] proportional control of servo-motor by beaglebone black

[flagadajones]

Hi,

For a personal project i need to control a servo-motor (esbe ara659). This 
servo motor has a proportional control with 0-10Volt range, or 0-20mA rand.

Could you help me to find how i can control it with my beaglebone black.

thanks

[beagleboard] Angstrom boot hangs up on "Uncompressing Linux"

[dexcelstraun7]

I'm trying to use a BeagleBoard xM for a robotics project. I've installed 
Angstrom on a 4 GB SD card as per 
http://treyweaver.blogspot.com/2010/10/installing-angstrom-on-beagleboard-xm.html.
 
I plugged the SD card into my BeagleBoard xM, configured minicom to 
interact with the BeagleBoard's serial terminal, and applied power to the 
Board. The serial console listed a lot of boot information, as you can see 
at http://pastebin.com/7wHQ25ke . The last line in the console, where I 
believe the error is, reads "Uncompressing Linux".

I also have an HDMI cable running from my BeagleBoard xM to my monitor. The 
monitor showed a loading screen with a loading bar at the bottom. When the 
bar was full, the screen then changed to a console output, 
as seen at 
http://www.majhost.com/gallery/DagonEcelstraun/Others/HelpNeeded/cam00112.jpg

My uEnv.txt is http://pastebin.com/z7fn5aTQ

Does anyone know what is causing my BeagleBoard xM to not boot?

[beagleboard] BBB Freeze then failure to boot

[rolf schatzmann]

Hi All,

I have a BBB Rev A6 (SN 3913BBBK1414) that I purchased from Sparkfun in 
November 2013. It has been running Ubuntu perfectly since it arrived in 
Dec. It has been running on a regulated 5v power supply and housed in a 
case.

A couple of days ago it stopped responding and then I checked it the PWR 
LED was illuminated but none of the others.

Nothing I did would get any of the USER LEDs to light up.

Connecting serial to the J1 header gives me the following output:

U-Boot SPL 2013.04-00017-g5c4fa11 (May 03 2013 - 10:48:32)
timed out in wait_for_pin: I2C_STAT=0
Could not probe the EEPROM; something fundamentally wrong on the I2C bus.
Could not get board ID.
Unknown board, cannot configure pinmux.### ERROR ### Please RESET the board 
###

All attempts to flash a different image or boot from the SD card fail with 
the same message. I gather that the EEPROM has lost it's ID.

Is there anything I can do to fix this or has the EEPROM died?

[beagleboard] USB audio dropouts and Xruns on BBB

[Michal Šmucr]

Hello,

i would like to ask you for experience with USB audio interfaces and BBB.
I'm having trouble with BBB (rev. A6A) and audio playback with 
snd-usb-audio under higher interrupt loads.
If i play audio through USB interface and for instance simultaneously 
transferring data from network mount, i will get audio dropouts. At first 
it is occasional thing and sounds like few milliseconds pops, but after 
while it happens more often and leading to serious stops at playback.
It is not completely possible to avoid this situation in desired usage (MPD 
based network audio player) as this happens for instance during library 
update, when MPD is rereading tags from all songs.

- it occurs more often during streaming of high bitrate audio (eg. 
uncompressed stereo 176.4kHz)
- ALSA driver access optimization doesn't help - memory mapped, different 
buffer and period lengths.
- forcing PIO mode with CONFIG_MUSB_PIO_ONLY doesn't help
- just for test i also tried network access through second USB port 
(virtual USB eth. interface) to exclude TI ethernet driver, but it is same.
- it doesn't seems to be userspace CPU usage issue (tried to generate CPU 
load with fio and it didn't produce dropouts)
- system doesn't print any other warnings or errors except of Xruns from 
ALSA layer. 
- I've tried several distributions with kernels 3.8.13 (Angstrom, Volumio), 
3.12.9 (Voyage), 3.13 (development version of Debian Jessie from RobertCNelson 
image).
- just for completeness, it is not issue of my USB interfaces (works great 
with other Linux systems and some are not bus powered to exclude possible 
issues with insufficient power from BBB USB port)

My quick steps to reproduce.. initiate playback of hi-res audio wav from 
mmc with aplay and simultaneously open several parallel network TCP 
connections with iperf.

Can anybody confirm me this issue with BBB? Do you have some tips, what to 
try next?

Kind regards,

Michal

bit of file storage, an maybe mp3's movies etc.
I would like to sync my Contacts and Calenders with android and Mac OS, 
I thougt about the Beaglebone Black with Owncloud connected with a USB Hard 
drive, and a Ethernt connection to my network.

But befor i start i have some questions:

- Will it be powerfull enough? (it doesn't need to be super fast)
- Which OS should i choos? (ubuntu, ubuntu server, CentOS...many more)
- is Owncloud the "right" Software for this? Any alternativs?

Please share your thoughts, ideas, alternativs!

I'm thankfull for every input
Thank you for your answers and sorry for my bad english its not my nativ 
language.
BR Gabriel

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

[Thomas J]

Hi
any news on this issue ? I have the same problem with my beagle xm, with 
linux not running anything and it still reboots after 1 to 5 minutes
If there is anything electric to do to make this work (add a capacity in 
front of the 5V power supply, ...) I can do it, I have lots of electronic 
tools at work

Btw, I am logged in through tty and I see

Broadcast message from root@arm
(unknown) at 11:40 ...

The system is going down for reboot NOW!
[  143.036193] Restarting system.

so somehow it might not be a complete physical problem, the system knows 
about it
(Linux version 3.7.10-x9 on Ubuntu 12.10 and beagleboard xm)

[beagleboard] BBB with ROS Training Class February 15th -- Mountain View, CA

[Greg Maxwell]

Hello Everyone,
Saturday February 15th 9:30 am to 1:30+
Located in Mountain View, CA at the Hackers Dojo Classroom 

We are presenting a Full Day Seminar on how to get started with ROS on a 
Beagle Bone Black (BBB). You will leave with a working motor controller 
fully controlled via ROS and learn step by step the process for wiring ROS 
into BBB and 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/";>
http://ros-training.com/courses/control/beagle-bone-black/

Registration are available at 
http://www.eventbrite.com/e/ros-training-beagle-bone-black-with-ros-tickets-10142084247
"

$65 without a BBB, $125 with a BBB,

We look forward to seeing you there. Please feel free to give us feedback 
and how we can improve these offerings.

Sincerely
Greg Maxwell

[beagleboard] GSOC 2014,

[mjunaidmuzammil]

Hello, 

I am Junaid, one of the postgraduate students interested in applying for this 
year GSOC. On going through the idea list, I was really attracted with a couple 
of project ideas including Bonescript projects and Openembedded support for npm 
package for node.js. The qualification requirement seems to be fine for me. 
Along with that I have a couple of publications over ARM targets as well. 

So I am enthusiastic for GSOC this year and would definitely like to have some 
advice prior to application submission.

Regards,
Junaid

[beagleboard] Re: Flashing Compiled Kernel

[Moon Walker]

This (install_kernel.sh)was not working for me too...


I simply copied the compiled modules from the NFS server to the appropiate 
directories *with winscp* and rebooted the rig...
Works fine now.

Re: [beagleboard] BBB Freeze then failure to boot

[Gerald Coley]

Sounds like something may have died. But it is rather hard to debug
hardware via email. I suggest that you try an RMA request and get it looked
at.

If your image is on the microSD, just stick it in and run
"./tools/install_kernel.sh"

If you've flashed it to the eMMC, well it's not that trival.

Come on guys! Is the "eMMC" local to the install script, no... Aka unless
the install script is physcally "running" on the beaglebone?? Then, duh,
there is NO way for the "./tools/install_kernel.sh" to flash the eMMC..

Copy the zImage/modules/dtbs yourself to the eMMC and install them in the
appropriate place..

/boot/uboot/zImage
/boot/uboot/dtbs/

/lib/modules/

Can you please retry with:

http://elinux.org/BeagleBoardDebian#BeagleBone

cd /opt/scripts/tools/
sudo ./update_kernel.sh --beta-kernel

Which will pull in "v3.13.2-bone5" which includes some new usb patches..

It's a new feature of the "eMMC" spec, it's not utilized by current am335x

2048 was set by the creator..

fat12's been around for a long time, just not normally used today:

It depends on your application... Just remember, flash wears out, using
swap definitely doesn't help that issue..

On quick review, I'd say other then unifing the "fatls/extls" sections to
just use the "generic" ls commands  as CONFIG_CMD_FS_GENERIC has been
defined by default since atleast v2013.10 (haven't looked earlier..)

Don't use the "subarch" flag with make-kpkg, it's for something else, not
related to the "soc" family of arm devices..

[beagleboard] Re: Frustrated trying to do basic things...

[doog]

I just check and BONE_D64.exe linked on the Getting Started page was 
working and downloaded a 1.1MB file. Gotta love how fast BB.org folks fix 
things.

Because you didn't say anything about a USB network device which should 
load up along with the flash memory device I would say reflash to the 
latest Angstrom image and then see what happens. If you've got a Linux 
distro running in a Virtual Machine you could try that as even the old 
images worked fine on 2 computers running old(12.04) and new(13.10) 
versions of Ubuntu.

The "latest" Angstrom image still contains a version of "BONE_D64.exe" that
was before this push:

https://github.com/beagleboard/beaglebone-getting-started/commit/6e2240697a83697c84eb9f9f10a6fd976f5c3ce8

That push contains a signed driver, very useful for users stuck on
8.0/8.1/etc..

So I should use this exact build string, but without --subarch and will get 
an armhf kernel with omap3 ?

Do you guys not use swap? 

my purpose for this device is to run a filtering proxy server for my home. 
I have kids with different needs and different levels of filtering. I had 
not considered flash wearing out. My understanding is that it would take 
years. But I had not looked in to the matter. I think it will use micro sd 
card till have a working solution. Then consider where I put what 
partitions. 

Do people using the BBB with SD not normally use a swap partition?

Thanks

The answer to the first part should have been implied from my last email..

The second part, totally depends on what features you enabled for the
"omap3" devices in your kernel .config.

Depends on workload, for a simple proxy you don't need it.

With 512Mb of ram, for most applications users don't need swap.  So review
your workload. ;)

Yes. You could implement a message passing bus (websockets for example)
which the C program responds to. Therefore you run your C program in the
background waiting for a message on the bus, then you get your web
application to send a message to the program telling it turn on/off an
LED. The C program runs as root and as such has control of the hardware
and your webapge never calls the C program, but only sends data on the
message bus, so as such it's a bit harder for anyone to do anything
untoward.

As far as I can see your "universal" device tree overlay expects to find 

/sys/devices/bone_capemgr.*/slots 

which seems to be gone in 3.13.x

More then likely yes.. But it depends on the kernel version.. So go
build/test/enable/rebuild/test/etc...

I configured it generally for omap2+, omap3 and beagle. Should there be 
more features to enable to have it run on BBxM with Ubuntu Precise ?

 So I should use this exact build string, but without --subarch and will 
 get an armhf kernel with omap3 ?

Oh, I did. Have reconfigured, rebuilt and tested 4 times by now, and keep 
getting the dpkg message that it's not an omap kernel.
I took vanilla kernel 3.5.7 because of a necessary patch that supports this 
version. Is there any other kernel version you can recommend for omap3 ?

 The answer to the first part should have been implied from my last
 email..

 The second part, totally depends on what features you enabled for the
 "omap3" devices in your kernel .config.

Okay, so it's not debian the image i'm developing for beagleboard.org.

You should go ask armhf.com why their image is randomly suspending..

OK. Can you tell me about the difference with regard to omap between 
3.13.2, and e.g. 3.5.7 or 3.8.13 ? These are all stable kernels.

a few years of development.. Mostly has been the complete removal of the
classic board files to device tree's.. Checkout kernel.org for all details..

or:

Sorry Robert, I was not aware of your image. I am still quite new to BBB or 
BeagleBorad and arm in general. I looked all over the beagleboard.org site 
but only found documentataion for ubuntu, android and angstrom. I didn't 
see Debian. I know many or most consiter ubuntu and debian the same.. I do 
want to run headless no matter what and I found angstrom.. was not what I I 
was looking for. I did not want to learn a new operating system. I am 
familiar with Debian. soo thats why I was looking for a Debian image.

is there a debian headless image on supported on beagleboard.org? if not a 
could make due with a stable headless ubuntu.. but it feels like an 
imposter (thats a joke) :)

at some point I think I will want to compile my own kernel as well. but 
that is some way down the road. I have not compiled one sense i was in 
school. even headless there are lots of things I think I could live without 
for a proxy.  

so.. is there a headless debian image supported by beagleboard.org? 

thanks for putting up with me. there is a lot of information to take in, in 
a short time.

Ron

That's just to make sure the overlay is loaded.  There are no overlays
(yet?) in 3.13.

I'm game if it actually gets used.  There should be little or no
difference between 3.8 and 3.13 as long as the pinmux-helper and
gpio-of-helper are available.  And they should be easy to port if not.

So the image i'm working on with beagleboard.org is posted here:

This was last week's image.

For a simple headless/server image take a look a this:

http://elinux.org/BeagleBoardDebian

Couple different install types, depending on which board you have from
beagleboard.org

[beagleboard] Free Up Space on BBB

[joshpeltier]

I have a BBB with angstrom installed. I am updated the system to try to get 
my wifi working, and I have run out of space after doing opkg 
update/upgrade. I was wondering if anyone could help me figure out what 
packages I can remove to free up some space. I don't need the gui, I will 
be running it as a webserver to controll my home brewery via bonescript. 
That is about all it will do. Any help would be much appreciated!

[beagleboard] kgdb over serial connection on BB xm running Angstrom: no stepping or breakpoints possible

[David]

Hi, 
I have got a problem using kgdb over a serial connection to my Beagleboard 
xm running Angstrom.

uEnv.txt contains:
[...]
kgdbwait kgdboc=ttyO2,115200 kgdbcon

The kernel is compiled with:
KGDB: ->use kgdb over serial console 
and 
->Load all symbols for debugging/ksymoops 
->Include all symbols in kallsyms

The board stops during kernel-boot and starts kgdb, as expected.

On my host machine (x86_64, debian wheezy) I used Bitbake 
(MACHINE=beagleboard ./oebb.sh bitbake -c compile gdb-cross -fv) for 
building a cross version of the gdb. Hope this is correct?

Re: [beagleboard] BeagleBone Black Availability

[Charles Steinkuehler]

Only in the general sense of pushing forward progress with LinuxCNC on
the BeagleBone in general.

Specifically, my Shapeoko V2 is still in the box  and I've been
working on getting the hardware setup so in can be understood and
implemented without cross-referencing 5 different ways of referring to
the GPIO pins and editing custom device-tree overlays.

I do know of a couple folks who have run Shapeoko machines with the
BeagleBone, so it's mostly just getting a configuration setup for your
specific hardware, and deciding how you want to handle the gantry setup
(ignore it and run two motors in parallel, use gantrykins, or hack HAL
to drive two motors off one motion axis).

[beagleboard] 3D Printer Cape for BeagleBone

[Charles Steinkuehler]

I have finished the initial design for a new 3D printer cape for the
BeagleBone.  Based on the RAMPS and RAMPS-FD, I'm calling the board
"Cape-RAMPS", or CRAMPS.  :)

At this point, I've just sent out the PCB design to OSH Park, but the
RAMPS-FD folks have been through a couple of prototypes already, the
original RAMPS is obviously a proven design, and I've been doing circuit
board for long enough (since 1986) I think the first version should work OK.

Features & Details:

* 12-24V operation
* 6 Pololu drivers
* 15A driver for heated bed, with dedicated power
* 3 high-current drivers for extruder heaters
* 2 medium-current drivers for fans/lights, always 12V
* 4 Thermistor inputs
* 6 Limit switches (5V tolerant)
* 4 Servo outputs
* SPI and I2C expansion headers (5V tolerant)
* Flexible power options for the BeagleBone (use 'Bone 5V jack, screw
terminals, or add a regulator to generate 5V from 12-24V system power)
* Hardware ESTOP chain
* Stack-through design allows for expansion

I hope to get boards back around the end of the month, and have the
hardware fully checked out and verified by the end of March.  I'm hoping
once the design is proven someone will build and sell them inexpensively
(ie: the "direct from China" eBay sellers of RepRap supplies).

 anyway with a checkout from any branch, I'm not sure that xenomai will be
 compiled as from docs, blog, forums, book
 it's clearly precise that not all kernel version accept xenomai patches.
 Therefore, from my understanding only 1 commit is currenlty guaranteed to
 work :

[beagleboard] Customizing BBB Angstrom Kernel?

[Mark Hatch]

Hi friends,

Total newbie here, so forgive me.

I'm
 
trying to add functionality to iptables so I can use the BBB as a ad-hoc 
"router", sharing it's Ethernet connection with others.

>From what I've gleamed so far I need to add that functionality by 
recompiling the kernel.

So following the links at http://www.angstrom-distribution.org/ i cloned 
the setup-scripts.

MACHINE=beaglebone ./oebb.sh config beaglebone

MACHINE=beagleboard ./oebb.sh update

. environment-angstrom-v2013.06

bitbake -c menuconfig virtual/kernel

I then change the options I need, but when I built it made a zImage file... 
Which confuses me.

Now what I don't understand is that the image I want should be based off 
the regular systemd image.


   - 
   
   bitbake systemd-image
   
   
How do I update the kernel configuration from the systemd image without 
just building the regular image?

A step-by-step explanation would be awesome, cause I've never 
customized/built the linux kernel before.
I also do not have a serial cable yet. Is this necessary for running a 
custom kernel? Do options in u-boot need to be changed?

I'm sure I'm asking all the wrong questions, but would really appreciate 
some help!

Here are the options that I need:

Re: [beagleboard] Re: CapeMgr in 3.13?

[William Hermans]

Charles,

Personally, I think the other idea you had ( default device tree overlay ?
) is a better idea.  It is kind of the same thing, but perhaps no dynamic
loading while the OS is live. Which in my humble opinion was never a good
idea anyhow( live pin-muxing ).

Re: [beagleboard] Control hardware from webserver

[William Hermans]

Jack,

Ok perhaps I am missing something, and I by no means mean to be adversarial
here. I am just curious, so If i  am missing something please feel free to
enlighten me.

What is the difference between using setuid(0) and having a web socks app
running the app ? Here is my thinking. If you write the app/service
correctly, all anyone is going to be able to do is switch on / off an LED.
Yes, perhaps you do not want *EVERYONE* doing this, but how will this
solution solve that specific problem ? Unless I am missing something . . .
nothing can, short of having a user login screen for the web interface.

So I am not looking for an argument so much as enlightenment . . . as I
have personally given this situation some thought over the last 6 or so
months( being new to embedded Linux, and thus web appliances ).

[beagleboard] Re: Customizing BBB Angstrom Kernel?

[Rusty Wright]

Do you need iptables?  When I last had to deal with routing stuff I ran the 
gated routing daemon, although
this was on a Sun server that had a bunch of ethernet interfaces on it. 
 Sun Solaris didn't have iptables back then.

Re: [beagleboard] Control hardware from webserver

[William Hermans]

My idea was to actually set environment variables to specific values for
different occasions, then have an app/service read the values of the
variables periodically. Whatever that is worth to anyone else . . .

Re: [beagleboard] Re: Frustrated trying to do basic things...

[William Hermans]

Larry,

Not sure what your experience is with Linux, and various distro's etc, but
you may be better off getting a copy of Robert's debian or Ubuntu running
on SD card, and then finally putting it on the eMMC if you're happy with
it. There are also several other distro's working out there as well,
including a BSD or two.

It has been my own personal experience that Angstrom is only going to give
someone grief. Partly because it does not exactly work very well( in some
cases ) and also partly because up to date accurate documentation for it is
not exactly easy to find.

[beagleboard] Re: Free Up Space on BBB

[Rusty Wright]

If you're connected to the BBB using the USB cable which uses the Linux 
gadget driver stuff
that makes the USB into a network that could be the problem.   On my BBB 
while I
have the USB cable from my PC plugged into BBB I'm getting a constant 
stream of debug
messages, which are going into the log files and filling up the disk. 
 Getting the ethernet
up and working allowed me to switch from using USB to ethernet for ssh (and 
unplug the PC's
USB cable from the BBB).

After I got the ether working I could see the debug messages start again as 
soon as I plugged
in the PC's USB cable.

Use the dmesg command to see if that's your problem.

[beagleboard] Re: Customizing BBB Angstrom Kernel?

[Mark Hatch]

Thanks for the response!

I have just been following various tutorials online that use the following 
command.

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Maybe even the following

iptables -A FORWARD -i eth0 -o wlan0 -m conntrack --ctstate 
RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT

Allowing the packets coming in via the ad-hoc wlan to be forwarded onward 
via ethernet.

I've seen this in several tutorials of sharing internet whether via usb or 
wlan.

However, if I run that command on the beaglebone I get an error saying 
iptables needs to be updated.

can't initialize iptables table `nat': (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

I'll look into gated a little more. I'm looking for any simple solution 
that works.

My idea is basically to enable as much useful SoC hardware as practical
via a single device tree overlay or via a static device tree (on kernels
without the cape manager).  The pinmux helper module then allows
run-time selection of the hardware you want to use for any given pin.

There's no way to avoid playing with the pin multiplexers when the OS is
"live" other than by editing the device tree and reloading.  That's the
problem I'm trying to get around...allowing run-time selection of
hardware without having to understand or compile device tree fragments.
