Hi,

I have built a buildroot image for BeagleBone Black using
beaglebone_qt5_defconfig config. The problem is with eglfs backend and SGX GPU
driver in turn swapping red and blue channels when rendering on 16-bit 7'' LCD
cape. Not tested with HDMI. It seems that SGX driver uses BGR instead of RGB
color mode (or vice versa).

fb-test application displays correct colors, everything matches. 

Any clue if it is possible to get an updated version of SGX driver which
resolves this issue. 


Thanks,
Nikola

--- Comment #1 from Peter Korsgaard <jacmet@uclibc.org> ---
The am335x has a known hw bug regarding red/blue swap when configuring the RGB
output for 16 bit mode, so it is probably related to that.

Why things are working for SW rendering and not for GPU rendering I don't know,
but you will probably have more luck asking on the beaglebone list:

Issue is specific to the HW platform and is not related to Buildroot per-se,
therefore I'm closing.
