I am not very good at tree overlays, but from the one you have provided me i believe i would be abble to reduce it only to modify the LCD pins (I also need to disable mcasp, because I only use video and the pins for mcasp are used as other peripherals). I thing I tried to find the place in this

Thank you, i will try to use this overlay. You are probably in US, thats a pitty for me because there is a big time difference which brings longer help delay :P. W dniu 2014-11-21 o 17:06, Robert Nelson pisze: On Fri, Nov 21, 2014 at 10:04 AM, Bremenpl wrote: I am not very good at tree overl

Hello again, I am just trying to export the compiled .dtbo file but I have to unexport the residing hdmi overlay. When I do that with echo i get kernel panic and my ssh session is lost. I would like to comment out the export at boot but I dont know where to find the place I should do it in con

I have found the uEnv.txt file in boot directory but for a long time now I cannot find where are the .dtbo files stored in console image of debian. I am putting my .dtbo file in /lib/firmware but when trying to echo its name to slots it doesnt want to pick it up from there. W dniu 2014-11-21 o

Re: [beagleboard] Change I2C bus for video communication

Okay, I have managed to load the tree overlay by hand from /lib/firmware/. What was wrong was that I havent followed the naming style. I have changed the name of .dtbo file to BB-BONELT-HDMIN1-00A0.dtbo and I could load the tree overlay by hand. Although, the overlay didnt want to load automati

Thanks for help with the boot loading of tree overlay, it works. But monitor still doesnt display anything :/. At least I know its not because of loading after boot. W dniu 2014-11-24 o 10:56, Jason Lange pisze: On Mon, Nov 24, 2014 at 1:52 AM, Bremenpl > wrote:
