hello:
Base on ti-processor-sdk-linux-automotive-dra7xx-evm-03_04_00_03, How can fixed the HDMI output resolution with 960(H)*1280(V), where is the source code path in the PSDK. Currently the dra756 HDMI Output relate to edid, but the TFT resolution :960(H)*1280(V) is not standard. We want to fixed the HDMI output resolution = 960(H)*1280(V), do you have some suggestion can change this?
we edit ":~/projects/linux/drivers/gpu/drm$ vim drm_edid.c" to add the new edid (we are not sure this edid is correct ) but"
[ 3028.633223] [drm:drm_load_edid_firmware] *ERROR* Requesting EDID firmware "edid/960x1280.bin" failed (err=-2)
[ 3032.355862] platform HDMI-A-1: Direct firmware load for edid/960x1280.bin failed with error -2
"
Thanks a lot
Neo
