[yocto] Compiling raspberry2 with eglinfo-x11

Thu Mar 17 03:00:16 PDT 2016

Hi all,
I just wanted to add that I got the qt5everywheredemo running. However it 
seems as changing the GPU_MEM variable is not picked up correctly when 
changing it. I had to change my boot type to uImage (which did work because 
the raspberry pi did not boot up with it) and back, then I had the desired 
amount of video ram and the demo was working.

Regarding picking up variables: My override to the yocto splash image does not 
work always as well. Sometimes my image is taken and some times the yocto 
splash image. Just seems random to me. Are there any logs where you can see 
why what bbappend was applied?

Thank you very much,
David Weisgerber
