(e.g. MSP430 and ARM Cortex M) can learn this embedded linux from the
begining? can you provide a guidance? a series of

Both of my two boards running Angstrom with GNOME have the very same
problem. Tested with Angstrom production images 2013.06.06 and 2013.08.21
(both booted from microSD). Opening even small images crash the GIMP
application. I don't think it's a power supply related hardware issue.

So, I've trashed an old laptop, and I have this nice 13 inch LCD screen
that is sitting in my drawer.
I was planning to use it for some project, and I thought that the BBB would
be perfect.
From what I understand, to use the LCD I need a LCD controller, which per
se is an inverter and a

Hi,
I want to build a case for my LCD7+Beaglebone black.
For that I need to drill four holes for screws at the exact position

Dear garyamort,
Since the book is written for the Linux Kernel version 3.2 and the current
version is 3.8 do you think I will have any problem?

I think I found a better solution now.
Opening /dev/mem was done by
info-mem_fd = open(/dev/mem, O_RDWR);
before, i changed it to
info-mem_fd = open(/dev/mem, O_RDWR | O_SYNC);
Now it works with the speed I expected and I don't have to drop the cache.
I'm not really sure if I should also use the

2. Why is a DT used to define the HDMI
Because this is a system-on-chip. The HDMI, gpio, gpu, pruss, etc are
all peripherals of the cpu that are located on the chip, but still separate
from the cpu.

Hello,
I'm afraid I have a mysterious problem and I was wondering if anyone
could shed any light on it?
I am trying to run quite a bit of a code on a Beagle xM, Rev C and I
get random segfaults and/or SIGILLs.
These turn up, occasionally, in every program I attempt to run -

I have tried with 3 different micro SD cards, and I have the same problem
with each.
If I have a sd card in the slot on BBB, all four user lights light, and
freeze that way.
Once I remove the card and re-apply power, the BBB boots as normal.
What am I doing wrong here?

Yes, it is a LVDS; sadly I have no clue about the model of the LCD, since
has no identification marks...it is plain white, was in an old macbook

Did some research, and they used 3-4 different panels, so it is hard to
pinpoint exactly which is it.
So I am

Update to above, I realised I was using Wheezy 7.0 and there was a 7.1
available, so I tried that, updated and installed LXDE, and some of the
issues are resolved, however now the mouse pointer jumps all over the
place, same as what happens on Angstrom.
