Hello,
Also through the serial debug port I observed the booting stuck at
following line for 20 seconds,
*Waiting for root device /dev/mmcblk0p2...*

IIRC the MAC is stored in an .nvs file. If so, you might be able to modify 
it using the calibrator tool. But I'm not sure if this is available in the 
angstrom image.

[Kishor Dhanawade]

Hello Robert sir,
   Thanks for quick reply. Ubuntu is booting from eMMC
because I am getting ssh access on my host PC. But display is not working.
I am showing a splashscreen using fbi package and init.d script. Using
serial debug port I found that fbi can be issue. But I am totally confused.
Is there any solution or direction to solve this problem? Thanking you.

Regards,
Kishor

Re: [beagleboard] BBB and internet

[doog]

If you can't run a command someone lists then you need to install the 
package which provides that command.
You'll need to lookup how to install iptables on your host system( as in 
apt-get install iptables for Debian systems )

Re: [beagleboard] BBB and internet

[doog]

I kinda expected people to look at what the script was doing so I didn't 
not explain every aspect of how it works.
Looking at the setup-bbb-ipforwarding script you see the line which starts 
with scp? that is like "cp" and it copies files so looking at it you should 
see that it is trying to copy the setup-bbb-ipforwarding-onBBB to the BBB. 
and there is no path for that file specified so it MUST be in the same 
directory you are running the host script from.

after the "scp" command you should see the line beginning with "ssh". that 
is running a secure shell to the BBB and tries to run the "-onBBB" 
script. So if it is not there it can't execute it.

If you look in the -onBBB script you will see it is just a list of the 
2 things which set the route to the host computer and set the name server 
in /etc/resolv.conf.

[beagleboard] Is it possible to make a tmpfs that is initialized?

[Neabex]

Is there some way to have a folder, such as /tmp , be a tmpfs folder, but 
initialized with what's on disk at boot-up?

I tried rebooting with the ethernet plugged in and the lights flash for 
about 35 seconds and it shuts down.  Now when I plug it in after it is 
running and do ifconfig eth0 for some reason has an external ip.  HMMM 

Will look at kern.log now.

Re: [beagleboard] Reading a Quadrature Encoder connected to a Beaglebone [black]

[Willie Warke]

Thanks for the reply! I actually used dmesg to figure out it was an HDMI
pin conflict, so I disabled it and SSHd. Voila! It works like a charm. I
appreciate the support, and will surely have more questions down the road.

[beagleboard] Re: BBB - won't boot with wrong UUID for rootfs with Debian

[Brad Andersen]

Update:
Mr Nelson confirmed my thoughts and provided a means to fix:
 You can use this image as a recovery..

http://elinux.org/BeagleBoardDebian#BeagleBone

Just remember to hold down the boot button..

Then using
lsblk
ls -lh /dev/disk/by-uuid/

fix both

uEnv.txt (on /dev/mmcblk1p1 ) & /etc/fstab  (on /dev/mmcblk1p2)

Also, using a newer image for the flasher image fixed it also.

[beagleboard] BBB - won't boot with wrong UUID for rootfs with Debian

[Brad Andersen]

My BBB won't boot now when it tries to mount the root device.  I must have 
copied some file from another BBB and messed up something.

My guess is the /etc/fstab and /boot/uboot/uEnv.txt files.  Are there 
others?

I have tried using the BBB-eMMC-flasher-debian-7.2-2013-11-15.img, but I 
still get the same problem after removing the sdcard and repowering up the 
BBB.

What is the best way to recover from this?
Just remove all files on the eMMC partitions?
Other?

[beagleboard] debian: test images (2014-02-05)

[Robert Nelson]

Another week, more fixes, do you sense we are getting closer to release???

First, for tracking please report all bugs to:
http://bugs.elinux.org/projects/debian-image-releases

Kernel:
3.8.13-bone39 -> 3.8.13-bone40
* fix /var/log filling up: (disabled CONFIG_USB_GADGET_DEBUG)
* added CBB-Serial cape

Changes:
New bb.org mirror repo at beagle.s3.amazonaws.com/debian
xinput_calibrator fixes from Louis
/etc/init.d/capemgr improvemnts (now lists multiple overlay with a
comma seperator)
libsoc upgraded to 0.6

Camera people (3.1MP and RadiumBoards):
What userspace programs are we missing? gstreamer? OpenCV plugins?

I really want to include a default shell script that'll take a picture
and allow end users to validate the 3.1/Radium capes work.

https://github.com/RobertCNelson/boot-scripts/tree/master/device/bone/capes

Does your "cape" work?

Does your wifi adapter work? Are we missing it's firmware?

http://elinux.org/Beagleboard:Updating_The_Software

and what does your definition of don't work right mean? rtl8187 has been
in kernel source for a long time. I have no issues with any of my
adapters which are all rtl8187 based. I just have to patch for a
non-upstream feature for my use case. Explain more about what you mean
and I am sure more help can be offered. I do not use Ubuntu though so
can't say for certain there is not a bug in the driver for their kernel.

Did you ever have any luck getting this driver installed?  I tried on  

3.8.13-bone37 with kernel source installed and it still won't compile... 
and the included drivers with ubuntu don't work right.

There's no need to connect index or strobe. Make sure you don't have any pin 
conflicts with the hdmi pins. You can also troubleshoot by connecting the eqep 
pins to ground and 3.3v in turn. I used a couple spdt buttons.

Honestly, i don't know.. "it" kinda worked for video back in the v3.2.x
days..  Ever since the fall of maemo/Nokia, the main developer behind
gst-dsp stopped working on it.  So fast forward to today...  That's why i
purged it from the wiki...  It's broken un-maintained crap..

Re: [beagleboard] BBB and internet

[doog]

I thought this a handy thing to do so I put the BBB side commands in an 
executable script and then created another script for the host side. The 
host side copies(via scp) the BBB script to the BBB and then executes 
it(via ssh) and then sets up the host(Linux). Run the host side with sudo 
or as root.

--BBB side: file name: setup-bbb-ipforwarding-onBBB

#!/bin/bash

This definitely should _not_ happen!
If you have a DHCP server in your network, usually the router in a
home network, then BBB should simply connect like any computer and you
should be able to search for the BBB e.g. with nmap or in the logfiles
of your DHCP server.
Did you have a look at /var/log/kern.log after reboot?
Did you reboot with eth0 plugged in?

I guess this might be a hardware problem of your BBB.

pinging 8.8.8.8 and google.com say the same thing because 8.8.8.8 is a name 
server out in the wild wild Internet and google.com is a server out in the 
same space.
Your route table looks like mine so what's left is your host computer so I 
think you'll find the answer searching for how or why Windows does ip 
forwarding.

It's not a permissions problem.. Your mmc device node changed name..
Fix your bootargs & /etc/fstab...

Look into using UUID's..

[beagleboard] Re: BBB booting from SD card but with same contents as SD card into eMMC board is not booting.Why?

[doog]

there is a special flash/eMMC image of the Angstrom BBB releases so I would 
venture to guess there's something other than copying over a couple of 
partitions.
Unless someone who knows the ins/outs of the eMMC boot flashing process 
chimes in, you might research what the flashing images do so to found out 
what you might have to tweak to get your Ubuntu system booting from eMMC.

[beagleboard] xM Bare Metal video output

[dean . wedel]

Greetings to all!

I have a "bare-metal" build running on my xM Rev C Beagleboard with output 
going over the serial port.

Now I would like to begin using the onboard HDMI connector for video 
output. Does anyone have some "C" code that I can look at (and use) to do 
this via "bare-metal" on the xM board?

Thanks!

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

If you wait until you see stock, you may never get a board. Just place your
order and you will have a better chance of getting it sooner. Backlog are
filling up as fast as they go down.

[beagleboard] BBB and internet

[hacktorious]

Hello,

I received my new BBB in the mail a couple days ago.  I've spent a 
ridiculous amount of time to get something as simple as an internet 
connection and am not having any success.  I feel like I've been through 
ever post on the internet and am still not having luck.

Here is my situation:

I've plugged my BBB into my usb and am able to ssh to it.  However, the 
device cannot connect to the internet no matter what I do.  Now I think its 
messed up.

How can I revert the following command. I was following directions to setup 
internet sharing from my mac and ran the below command on the BBB.  Now I 
think its all messed up.
*route add* default *gw 192.168.7.1*

Furthermore, I am not able to use the network cable plug because the BBB 
just crashes and shuts down whenever I attempt this.  Even after I pull the 
cable out it tends to crash the next several times after I plug it back 
in.  The network cable seems to be performing some sort of black magic on 
the BBB.

Does anyone have any recommendations on the correct procedure for 
connecting my BBB to the internet?

Here is what I have:
Default emmc angstrom install.
Mac OSX Mavericks
Both BBB drivers have been installed on my mac

Please help.  Thanks.

[beagleboard] BeagleBone Black touch input problem with ESD protection

[moore.cyril]

Hi Guys,

I have been working on an expansion board for the BBB that includes a 
resistive LCD touchscreen. The problem that we are having is that our ESD 
protection diodes seem to break the break the touch input. 


We are using a 4 wire touch interface on AN0, AN1, AN2, and  AN3. The 
symptom we are seeing is that when the diode is connected to the touch 
interrupt seems to be triggered inconsistently. 

When checking the signals with a scope, it shows that the interrupt seems 
to work fine until an application that uses touch is run then it becomes 
inconsistent. This does not happen if the ESD diode is removed. The apps we 
are running are the Qt calibration and Qt touch test. Looking at the raw 
data from the touch device from within Linux on the BBB we see a steady 
stream of data before a touch app is run, then inconsistent data streams 
once a touch app is running AND after the app closes.  Again this symptom 
does not happen with the diode removed.


My question is 2 parts:

1)What could be happening that would make the touch interrupt inconsistent 
only when that diode is present AND one of these applications is run?


2) Do we really need additional ESD protection? Does Anyone have any 
experience with a BBB and a heavy usage resistive touch screen, that is not 
have additional ESD protection? In the two cape examples I looked at 
additional ESD protection is not used.  



This is the ESD part that we are 
using: http://www.comchiptech.com/cms/UserFiles/CPDT6-5V4U%20RevD364097.pdf

Thanks 

Cyril

Re: [beagleboard] Re: DM3730: working DSP and 1GHz

[Maxim Podbereznyy]

Robert,
first of all I need to bring up DSP. I executed the script
create_dsp_package.sh, got DSP_Install_libs.tar.gz, copied it to a target
with debian running, unpacked, ran install-DSP.sh. Then I ran "/etc/init.d/dsp
start" and now I want to test DSP somehow. Can you poke into instructions
how to test DSP? On the web I found that it was possible to run something
like "dsp-test", but I don't find it in my installation

SGX:
I can see https://github.com/RobertCNelson/tools/tree/master/x86/ti_omapscripts:

 create_dsp_package.sh


 create_sgx_package_2.6.37.sh


 create_sgx_package_3.2.x.sh

should I run create_sgx_package_3.2.x.sh?

Back in the 3.2.x days, we did things a little different.. The sgx
drivers where built into the staging tree, so we just needed the lib's
from the sgx bin. So there's an extract script..

I don't really remember a lot from that branch, not sure what still
works, probably mostly bitrotten by now..

You can override the mac address, thereby adding your own, by just
adding "hwaddress ether xyz" to /etc/network/interfaces

cat /etc/network/interfaces | grep hwaddress
hwaddress ether 00:19:b8:00:f0:88

It boils down to... qemu is bitrotten and just plain sucks...  At one
time it worked really great. (okay that's a lie, but it worked..)

See the note right before the git clone.. ;)

Hi Robert 
I've (of course ) the same problem with my distro that is a 3.8.13-bone37 
I did the bone35 kernel update and it worked perfectly.  yet I'm wondering 
If I will have to "suffer" from any regression from 37 to 35 ?

[beagleboard] Setting a MAC address on beaglebone cape.

[ccsbrock]

Hi,  not sure if I am posting in the right place (please let me know if I 
wrong!)

I have two (white)beaglebones, each of them have the wifi cape with the 
TiWi-5 chips 
(http://elinux.org/CircuitCo:BeagleBone_TiWi-5E_w/_EXT._Antenna)

Getting them to connect to the network was no problem at all, it is after 
that the the problems occurred.
Only one of them would show up on the network at a time.
They had the same hostname and were being assigned the same IP address by 
the router, so after changing the host name and setting a static IP, I 
notice that the MAC addresses for both boards are the same, and the router 
is still only picking up one board at a time.

Checking both boards ssh over USB shows that they believe they each have a 
separate IP address and are connected. So I was wondering if anyone knew 
how to change the MAC address for the beaglebone with wifi cape. (I have a 
feeling it might involve EEPROM changes?)

I have not been able to find any information in relation to changing the 
MAC address with a wifi cape installed, yet alone much information for the 
wifi cape itself. Any help, or links to resources would be appreciated.

Thanks

Chuan

If you're using Angstrom, then get the timestamp-service package.  It 
should preserve the (approximate) clock time across power cycles.  The 
clock time is saved at shutdown and reloaded at reboot.  This doesn't 
account for time elapsed between shutdown and reboot, but it's usually much 
better than starting from zero.

[beagleboard] SGX Drivers for 3.8.13 Kernel

[Charles Steinkuehler]

There is a recent report of working SGX drivers for the 3.8.13 kernel on
the TI forums:

http://e2e.ti.com/support/arm/sitara_arm/f/791/p/298596/1110997.aspx#1110997

I won't have time to test this for several days, but if anyone here
wants to try building a 3.8.13 BeagleBone kernel with GPU drivers,
please give it a shot!

I'm not sure if the reported success was for a BeagleBone kernel or just
a generic 3.8.13 AM335x kernel.  If you do try to build a kernel, please
let us all know the results!  IIRC, the last time I tried this, I got
stuck on some issues with the patched-up HDMI support added for the
BeagleBone that kept the kernel from building properly.

Hey Robert,

With device tree on the beagle/beagle-xm I've only enabled the i2c
functionality on the expansion bus. I need to also enable spidev..

but looking at page 109:
https://github.com/CircuitCo/BeagleBoard-xM-RevC/blob/master/BeagleBoard-xM_revC_SRM.pdf

For the other pins, what pinmux would you want for your class? (should
we enable the other uart?)

I don't have a BB xM, but which LEDs are you using?  If you are trying
to use the on-board LEDs that are assigned to things like CPU load and
SD card access, you can't export the GPIO controlling that LED to user
space because it's already "claimed" by the kernel.  If you really want
to drive the on-board LEDs, you need to edit the device tree so the GPIO
is not claimed and the LEDs will disappear from /sys/class/leds/

The article uses a pin from the expansion connector, and from what I can
tell the instructions should work assuming you use the proper GPIO pin
number.

[beagleboard] how to activate LED on BB xM using gpio?

[Robert P. J. Day]

  in an embedded linux class i was teaching last week, the students
were all using beagle xMs (rev C), and we decided to experiment with
playing with the LEDs from user space.

  using the LED files under /sys/class/leds worked fine -- changing
the brightness, trigger and so on. but using this article as a basis:

http://makezine.com/2009/02/03/blinking-leds-with-the-beagle-board/

we simply couldn't control the very same LED via gpio. we followed the
article, tried changing the LED trigger and so on, but nothing worked.

  can anyone with a BB xM (Rev C) verify whether or not that article
works for them? let me know which LED you pick, the GPIO pin number
you use, whether you need to change the trigger, etc. i'm sure i'm
missing something trivial, i'd just like to figure out what it is.

[beagleboard] BBB booting from SD card but with same contents as SD card into eMMC board is not booting.Why?

[Kishor Dhanawade]

Hello,
   I am using BBB with ubuntu-12.04.3-LTS(3.8.13-kernel). I was 
working with micro-SD card. Now I copied both boot and rootfs partition 
into eMMc.  I checked all the permissions so permission is not issue. 
Exactely same copy of SD-card image is in eMMC. Still board is not booting 
from eMMC. What can be the issue??? Thank you.

Regards,
Kishor

[beagleboard] DM3730: working DSP and 1GHz

[Maxim Podbereznyy]

Hi Robert!

I use your scripts to build a kernel. When I built 3.7.x I could see a
number of issues which I never saw in 3.2. If I change to 3.2 branch will
it support DSP and SGX? If yes then how to build support for them? I don't
see respective scripts in the 3.2.x branch

best regards,
Max

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

[Ronny Julian]

Yea it is but shipping is not that bad.  They will ship it or I could if
the person that needed one wanted to write me.  SSeeing as everyone else is
out.  Ya gotta stop thinking so negative there!
