It looks like it is running, just the HDMI is turned off.
You should be able to ssh into it through the USB cable and modify the uEnv.txt
to re-enable the HDMI.
Or, plug the SD card into a computer, modify the uEnv.txt on the computer.
It may be bypassing the SD card when it boots. Are you

Apparently, I fix the problem !
I don't know really why, because I just reflash it with a old debian
image(like as did 10 times)

I'm sampling data from the ADC and doing some processing on the PRU unit.
After that, I pass the processed data to a linux app in the ARM processor
using shared memory. Sometimes when the ARM processor is busy, I miss some
of the samples so I'd like to use a ring buffer.

If I'm writing and reading from the PRU and the ARM to a position in shared

Use 32-bit (or smaller) naturally aligned values in the PRU data ram and
accesses will be atomic on both the PRU and the ARM
Use 32-bit (or smaller) naturally aligned values in the PRU data ram and
accesses will be atomic on both the PRU and the ARM side.
So, something like this will do the trick (for atomic access)? on the PRU:
// Address 0x1 is refered to as shared data in the PRU local data
memory map.

I've been googling and watching device tree tutorials... all targeted at
3.8 kernel.
This is great for learning the basics, but I have 3.14 kernel: Linux
beaglebone 3.14.19-ti-r30 #1 SMP PREEMPT Mon Oct 13 20:34:06 UTC 2014
armv7l GNU/Linux
From what I can find, the friendly device tree tools
I just saw the post below mine (how did I miss it before?) that mentioned
https://github.com/cdsteinkuehler/beaglebone-universal-io
for 3.14 kernel.
I'm reading through it now, sounds like it may answer my question...

Hi all,
I have an AM3352 bases custom board. I've tried to configure framebuffer driver
for small RGB 320x240 TFT LCD in linux-3.8.13 but it doesn't work. In the old
kernel linux-3.2.0 I can modify some file such as board-am335xevm.c, da8xx-fb.c
and it works properly. The new kernel implements
I just ran across BBIOConfig (https://github.com/strahlex/BBIOConfig)
Very cool and easy to understand.
I saw there was a utility config-pin for setting up the pin configuration.
Does this work on BBB 3.14 now?
Is there an apt-get install package that will install it?

Thanks for the reply Robert,
I've tried several times dd'ing the card (also tried Wind32 disk imager).
I've noticed that even uboot nor the Angstrom distro cannot detect the card
when I plug it into the board. I tried lsblk -l with no success.
That is why I was asking, since the microSD will
