Hi,
so trying to get my things up and running, I wrote a program for the PRU in
asm to toggle 2 pins and read 4.
In C, I manage to manipulate them because I'm using GPIO.
But in asm... I try to interact with r30 and r31, and nothing really
happens...
Im with kernel 3.15.
Could someone guide
compatible=gpio-keys or
something else, I did not find anything related to this yet.

I will try, but I'm checking diffs between 3.8.13 dts and 3.15.10, because
using dtb from 3.14 is not really a solution for me as I also need pruss.
Well I think :)

My very own fault, I had leftover TS things in /etc/profile pointing to

Hi all,
First thanks to Robert and other contributors for having put dts files for the
capes in the kernel tree.
I've been away from BBB those last weeks because of work, and back on it after
having played a bit with Qt5, opengl, pruss and ldc4 cape...
I found out my fingers are way too big
Thanks for posting,
I'll try that ;)

Hi,
if it claims to use the same driver as Circuitco, it will depends on which
version.
The LCD7 rev A3 seems to use i2c, and rev A3 uses adc chanels 4-5-6-7 as
per dts:
adc {
ti,adc-channels = 4 5 6 7;
};
You should be able to use chans 0 to 3.

quite like back to march 28th report , I have trouble building sgx

Building modules, stage 2.

Ok,
so after playing in dts and in kernel config, I finally managed to get

So now screen is white instead of black !!
I had to disable pwm examples in dts because of overlaping pin config.
Still digging.

so I did a rebuild on the kernel, sent the file to the SD, booted on SD.
