mmcblk0p2 (root).

Hello everybody,
I'm newbie in Beagleboard-xM, I had installed Ubuntu OS on bbxm, but I

but on Ubuntu OS, omap_mux directory just have 1 empty board folder. I

Hello Guys
I am using a BEaglebone BLack with Debian.
I added a service to startup using update-rc.d myprogram defaults.

Hello,
I am trying to setup BBB to play html5 videos in chromium and output

The status so far is as follows (Thanks to the images from rcn-ee.net):

* Installed the pvr kernel drviers.
* Installed the SGX userspace libraries and demos.
As an alternative to Robert's answer ...
If you have access to a Linux computer, you can plug the microSD card into
the
Linux computer and use the application Gparted to expand the partition to
the
full size of the card. Since Gparted has a GUI, you get to see what is
going on.

then the process is missing a controling terminal.
Try to start it with nohup from the script to verify that.

ok so i updated rc.local inside /etc
added
nohup /pathtomyprogram/program

works well.
the Plays an important role and also the /path has to be the custom path

Pin 17 and 18 belong to /dev/i2c-0 in my opinion.
So try to change your code to
fd = open(/dev/i2c-0, O_RDWR);
or use pin 19 and 20.
To find your device use the i2cdetect command.
For i2c-0 use:
sudo i2cdetect -r 0
and for i2c-1 use
sudo i2cdetect -r 1

You should re-read the thread. You'll find even Arch Linux ARM
can't solve this, as you'd still have to manually rebuild qt5 with

Sorry Arch isn't always the answer..

Hi everyone,
I tried i2c communication with p9_17 and p9_18 with /dev/i2c-0 and

Hi Anubhav,
do not move uEnv.txt, the U-Boot image and the kernel images
around. Due to the limited technical possibilities of the very early
boot stages, these files are exspected to be at certain physical

Instead edit /etc/fstab and remove the mount command of /boot.

Hi Anubhav,
one thing I did not know about your system is: Are you using

Critical files are more than only those under /boot.

the kernel is running... ;)

Ok, so I do not know where the module g_multi is loaded from on angstrom,
but g_multi is a USB to Serial, ethernet, and mass storage device. You

So anyway, g_multi is caled similar to this:

By the way, Linux is Linux, is Linux. Angstrom is in round about way even
based on Debian. Through Open Zaurus . . .Anyway, you're going to find it
more, and more difficult moving on with Angstrom I think . . .
