[beagleboard] Debian for Beagleboard Xm and ULCD7

[Jacek Radzikowski]

Hello,

It's been a long time since I used my Beagleboard Xm with ULCD7, so
yesterday when I dug it out while looking for something else, I wanted
to bring it back to life. I wiped the dust from the screen and booted
Debian downloaded from http://elinux.org.
/BeagleBoardDebian, but this image boots to text console. I haven't
used debian before (I really liked Angstrom. Koen did amazing job
making Beaglebone boot almost instantaneously, the distro is very
nice, and I'm really sorry he's not with CircuitCo anymore), but since
this is the current official distribution for Beagle boards, I want to
learn how to use it.
Having said that, is there an image for Xm which works OOTB with
ULCD7? I don't feel confident enough to hack apt-gets to manually
install necessary packages to boot the board to graphical environment.

Thank you,
Jacek.

[beagleboard] BeagleBone Black web server

[Michael Thompson]

I flashed Debian to the eMMC and it seems to be working fine. My plan is to 
host a small web page using Apache. I installed Apache and using the IP 
address the BeagleBone 101 loads fine from outside my network.

So, my question is, in what directory do I save my index.html file in order 
to see it as the default page served by Apache? There are no files in the 
/var/www/ directory so I am confused. On my Linux Mint (Debian edition) all 
I had to do was save my index file in the www directory.

Anyone know where I am going wrong?

Thanks!!

RE: [beagleboard] Re: Reading an Analog input from a web page ?

[William Pretty Security]

Hi Mark;

 

Thanks for the response. I looked at the links, and I think it would be easier 
if provided more detail.

What I am trying to do is a lot less complex (I think) than your examples.

 

As part of my latest book for Packt Publishing, I have an RF Power Meter design.

Basically you read an analog voltage which is proportional to the RF power 
being measured.

(It could just as easily be temperature) multiply by a correction factor to 
convert millivolts to dBm and then

print out the result.

 

I already have test software that does this to the console, but I want to now 
output it to a web page.

The web page already controls a programmable attenuator, using socket.io and 
toggling IO bits.

I don’t need to graph anything; just print a number on the web page that 
corresponds to the RF power.

 

I found a couple of files in your git tree called “ioPlot.html” and “ioPlot.js” 

but I am not sure how to simplify them for my application.

 

Thanks;

 

Bill

[beagleboard] 1 MBaud rate on uarts

[Charles Kerr]

I setup my serial ports on the BBB to have a 1Mbaud rate.  However, when I 
look at the output on the logic analyzer, I see the baud rate is more like 
1.214 MBaud.   This of course is too much deviation for my serial 
transmission to sync  up.  I tried setting a custom baud rate, and that 
just fails completely.  I wanted to use all four uarts.  If I need to, I 
could bit bang it from the PRU (but then limit myself to two versus four). 
 Is there a way to setup a more accurate baud rate on the BBB?

No problem. If you decide not to get the boards, that's fine. It was more

did it. I'd be curious about your board ... :)

weston: (running as root, in jessie)

export XDG_RUNTIME_DIR="/tmp/wayland"
mkdir -p "$XDG_RUNTIME_DIR"
chmod 0700 "$XDG_RUNTIME_DIR"

weston --backend=fbdev-backend.so

or

weston --backend=drm-backend.so --use-pixman

(fbdev actually works better)

This looks to have fixed the problem.

Regarding the source of the BBB, I don't know if it originally came from 
Embest; I purchased in through a major online retailer.

I presume updating Debian to the latest image would also have corrected 
this issue? Perhaps I'll give that a try next.

Thanks very much for the help.

Based on your error, I thought it might be that one. Any chance was
this one of the first embest boards? I know they has flashed a few
boards with an early pre-released version of the debian image. (this
was fixed in 2014-03-31)

[beagleboard] shutdown problems

[Troy]

I just purchased a new Beaglebone Black RevC and I'm starting to experiment 
a bit. I'm seeing some strange behavior when trying to perform a graceful 
shutdown of the board. When connected through the micro USB shutdown works 
as expected. When an external power supply is used, and I'm connected 
through Ethernet, I can't get the board to shutdown properly.

Following are my two experimental cases:

*Case 1 - Power through USB*

   1. Start with all cables unplugged
   2. Connect to laptop through micro USB
   3. Lamp for 5V power turns on.
   4. Beaglebone boots in about 30s
   5. Push power button on Beaglebone
   6. Beaglebone shuts down in about 6s
   7. All LED's are off.

*Case 2 - External power*

   1. Start with all cables unplugged
   2. Apply external 5V power.
   3. Lamp for 5V power turns on.
   4. Beaglebone boots in about 30s
   5. Push power button on Beaglebone
   6. Nothing happens!

In each case, I also tried connecting through an SSH session. In both 
cases, pressing the power button is issuing a shutdown command. I also 
tried explicitly issuing a shutdown command through the SSH session (i.e. 
shutdown -h now). When powered through USB it works; when powered 
externally the shutdown doesn't occur.

Any ideas or suggestions?

Troy

[beagleboard] BeagleBone Black Rev C doesn't boot from SD with the rs232 Rev A1 Cape installed.

[rob . lemon]

I had purchased a number of RS232 capes 
(http://elinux.org/CircuitCo:RS232_Cape_RevB Rev A1) before the Rev B came 
out, I also have BBB's rev A6A, B, and C. 
I'm needing to boot from the SD card, I've installed Angstrom on the SD 
card and everything works well except when I go upto Rev C on the BBB. The 
BBB refuses to boot from the SD card only when the cape is installed.
On the A6A and B with the cape installed everything works as expected, and 
if I remove the cape it boots from the SD on Rev C. 

I have been unable to get my hands on the new revision of the cape (sold 
out). My only thought is the eeprom is not addressing the BBB properly and 
somehow making it ignore the SD card.

So my question is actually two: 
Has anyone else experienced this problem?
and does anyone have the new cape and would be willing to send me a hex 
dump of the eeprom?

Thanks.

It seems BBB Rev C forces you to press the button to boot from the SD card. 
I have been unable to get it to boot from the SD otherwise. Tested on 6 BBB 
Rev C (what you describe is what I see on Rev B and Rev A6A)

[beagleboard] New Cape LCD timing problems

[Greg Wilson-Lindberg]

I'm building a new cape with a 5.7" LCD on it.  I've got the BeagleBone 
Black recognizing the EEPROM and loading the .dtbo file.  The UART2 
connection I'm also using is being initialized.

The problem that I'm having is getting the LCD timing to work out 
correctly. The 4.3" display cape is 480x272 pixels and the 7" display cape 
is 800x480. The 5.7" display that I'm using is 640x480 pixels. If I set the 
timing for the LCD display to the values used by either the 4.3" LCD cape 
or the 7" LCD cape the signals on the pins look like they should. If I set 
the LCD timing to the values necessary for my display or any combination 
that would produce 640x480 then the signals that come out look like they 
have been divided by about 64, i.e. the horizontal sync rate is 488Hz 
instead of 31.468KHz and the vertical sync rate is about 1 second instead 
of 60Hz, the pixel clock is only 390KHz but the width of the positive pulse 
is the same as what it would be for a 25.175MHz clock which is the 
frequency for 640x480 display.

Here is the relevant portion of the dts file:
panel {
compatible = "tilcdc,panel";
pinctrl-names = "default";
pinctrl-0 = <&bbb_lcd_pins>;
panel-info {
ac-bias   = <255>;

This is a long standing bug, that i didn't fix till yesterday..
"--dtb" only choose the generic multi platform kernel, thus the "--dtb
beaglebone" would not have much working.. With the "2014-05-06" use
"--uboot bone"..

Of course, i released a new image last night "2014-06-05" (maybe a
should have waited a few more days so the numbers were so oddly
close)..

Which "--dtb beaglebone" now works thanks to:

[beagleboard] Re: [beagle-alpha] New Debian 2014-05-14 image linked on beagleboard.org/latest-images

[Dominik Fretz]

Hi Jason,

After you asked the OpenROV project on Github on what to do to get OpenROV
over to debian I had a go at the Debian images.

I tried to get the latest Debian demo image (from
http://elinux.org/BeagleBoardDebian) running on the BeagleBone Black (I
think its a revision B).
I tested it with both, debian-7.5-console-armhf-2014-05-06.tar.xz
and debian-jessie-console-armhf-2014-05-06.tar.xz and wrote it to an SD
card with --dtb beaglebone.

But when I put it in the BBB it doesn't seem to boot up properly.
I can't get a network connection, not on the LAN port nor if I connect it
via USB to my laptop.

I checked the /var/log/messages and /var/log/dmesg afterwards and it ends
with a message that the root partition wasn't cleanly unmounted and should
be checked with fsck but nothing more.
The heartbeat is still going on though.

I will try to hook up a second BBB via UART to the serial debug output to
see if I can get anything more.

Do you have any hint in what could cause that issue?

Beside that, I will test the demo image from
http://beagleboard.org/latest-images/ too.

Regards,
Dominik

[beagleboard] elinux: ubuntu/debian: 2014-06-05 images

[Robert Nelson]

I don't normally announce updates on these monthly releases. (maybe
i'll change that)

But there's a "BIG" change to the flasher image. (Special Thanks to
Charles) He helped rewrite it from a normal script that ran at run
time. To one that's ran in single user mode. So the "source" file
system is now completely read only during the flash process.  In
theory this should help get us past some of the errors we've been
seeing with the old version. And as a special present, Charles tweaked
the led's so it's now "obvious" when the board is flashing the eMMC.

Just one little issue, the cpu does "halts" but the pmic stays on.
(it's fun trying to reboot/halt in single user mode) So just yank the
power when all 4 LED's are ON.

Give it some testing, I'd like to merge this "flashing" technique to
the beagleboard/debian image in a future update release.

Ubuntu I believe uses a different network manager. connman or some such

try googling -> Ubuntu 14.04 how to static ip

could you elaborate a bit more?

Thanks!

I don't think Jessie's 3.14-1 will boot the xm..

or just use this branch:
https://github.com/RobertCNelson/armv7-multiplatform/tree/v3.14.x

with your config tweak and really easy to copy the kernel files:

Pretty straight forward:

zImage/vmlinux -> /boot/uboot/zImage
dtbs -> /boot/uboot/dtbs
modules -> /lib/modules/

Many options really. You have SFTP, and ssh, among others. Hell, rsync may
even work for this.

Hi,

The easiest way is to use ser2net (serial to tcp server), and on java

Here is my version RXTX for ser2net:

[beagleboard] kernel 3.14 upgrade in debian, BeagleBoard xM

[Leonardo Gabrielli]

Hello group,
a rather newbie-ish question. I created my own customized Debian Wheezy 
system for a Beagleboard xM from armhf builds at rcn-ee.net (specifically: 
debian-7.4-console-armhf).

Now I am happy with all the tweaks I've done so far in the last months but 
I'd like to upgrade the kernel to a 3.14 release, in order to make use of 
the new SCHED_DEADLINE.

There are no backports of linux 3.14 for Wheezy but there are Jessie 
packages for 
linux-headers-3.14-1-all linux-headers-3.14-1-common 
linux-headers-3.14-1-all-armhf 
etc.
What's the best option to upgrade the kernel? Tweeak /etc/apt/sources.list 
to add Jessie repos or trying compile it natively (I'm too lazy for setting 
up a cross-compile chain).

Also, once I've got them compiled, I guess I should modify the BOOT 
partition of my uSD card to point to the proper image? An outline of the 
steps would be immensely appreciated!
Regards

Leonardo

[beagleboard] Re: Android Beaglebone black GPIO APK not functioning

[Ernesto Gigliotti]

Hi, I made this Library "ALLToolKit" for android, using JNI (where it was 
necessary) you don't need to use JNI for GPIO control:

https://sourceforge.net/projects/alltoolkit/?source=directory

with this library you can control GPIO,I2C,SPI,UARTS,PWM,ADC (you need 
Robert Nelson's 3.8 kernel for PWM and ADC), you will find an example for 
GPIO and a script for GPIO initialization.

no more "bumping" please

bye

[beagleboard] Hooking up a bbb to xbox360 to use it's wifi internet connection..?

[eric . ebling . ee]

Hey all, so I have no experience with the BBB and am wondering if this 
would be possible. I have an xbox 360 with the wifi module so my xbox can 
use the internet connection in my apartment. Is it possible to connect the 
BBB to the ethernetconnection on the back of the xbox and use the wifi from 
the xbox to get online with the BBB.? I have the BBB connected to my tv so 
the xbox is right there and it would be cool if i can somehow just use it 
as my internet connection. Thanks for any info.

Re: [beagleboard] Re: BeagleBone Black doesn't sometimes start. Only Power LED is on

[verster . cornel]

Hello Andrew

Thank you so much for this post! I'm having the exact same problem, and am 
in need of getting the golden 100% boot ratio :)
I've been using linux for about a year, but am still not trusted with the 
building of kernels and modules. I had a look at the link that you posted, 
but am still not trusted with what is going on exactly.
Will it be possible for you to give me more detail about what exactly we 
are doing by rebuilding the u-boot and the neccessary steps?
Also, about any other steps that need to be taken (deleting the MLO file on 
the eMMC -> what is it and what are the effects of deleting it).

Or refer me to somewhere where I can learn more?

Kind Regards
Cornel Verster

Hello Andrew

Thank you so much for this post! I'm having the exact same problem, and am 
in need of getting the golden 100% boot ratio :)
I've been using linux for about a year, but am still not trusted with the 
building of kernels and modules. I had a look at the link that you posted, 
but am still not trusted with what is going on exactly.
Will it be possible for you to give me some more details on exactly what we 
are doing by rebuilding u-boot and what the steps are in doing so?
Also, any additional steps required (deleting the MLO file from the eMMC -> 
what it is and what the implications are).

Or refer me to somewhere where I can learn more on these topics.

Kind regards

[beagleboard] New angstrom image installation problem

[tabishsaifullah]

I am a newbie in beaglebone black.Yesterday I install Ubuntu in my 
beaglebone black which work great, but now I want to install Angstrom, so I 
download image for angstrom 
(Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.08.21.img) 
.Then extract it using using "7-zip", using "Win32 disk imager" I write it 
into 16 GB SD card. Then I put my SD card in Beaglebone Black and press 
boot button. Now I insert 5V 1Amp dc adapter. After making sure that all 
four LED's are on I release boot button.
  Now problem is my four LED's keeps blinking. I check it for 
more than one hour but its still blinking. According to the tutorial it 
should get stable after 35-45 minutes.I please tell me where I am doing 
mistake.

Thanks

[beagleboard] About wlan0

[Kazz]

Hi all
On beaglebone black, I'm using Ubuntu 14.04 prebuilt image.

I have a problem.

I tried to connect with wifi.
I edited /etc/network/interfaces.

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
# iface eth0 inet static
# address 192.168.12.111
# netmask 255.255.255.0
# gateway 192.168.12.1

auto wlan0
iface wlan0 inet static
address 192.168.12.101
netmask 255.255.255.0
gateway 192.168.12.1
wpa-ssid "wifi1"
wpa-psk "password"

dns-nameservers 192.168.12.1


in the state that does not connect the eht0,
If eth0 is dhcp , wlan0 can connect.
If eth0 is staic , wlan0 not be able to connect.

What is solution?

Thank you.

If the objective is to have something working right now, you can take a
look at the motion package, that does that and much more:

sudo apt-get install motion

[beagleboard] Some help required

[Alastair Gilmore]

Hi, I'm working on a project to grab images from a webcam and send them to 
a web site, triggered by an alarm system. I have the image grab working and 
saving the files, all low res. about 60Kb. I'm not sure how to send these 
automatically to the web site. I write in 'C' and am looking for a tutorial 
to automatically invoke FTP or some other method to periodically connect to 
a web site and send the files.

I'm using Ubuntu 12 LTS on the BBB.

Any guidance would be greatly appreciated.
