Tool/software: Linux
Hello,
We are using a custom board having AM5728 processor, The board has HDMI and RGB (through LVDS) interfaces. It works fine, if I use arago linux version of kernel 4.4. When I use 4.9 kernel, it doesn't work.
# modetest trying to open device 'i915'...failed trying to open device 'radeon'...failed trying to open device 'nouveau'...failed trying to open device 'vmwgfx'...failed trying to open device 'omapdrm'...failed .... no device found
I have grepped log for v. 4.9:
# dmesg | grep drm [ 2.331052] [drm] Initialized [ 15.722112] [drm] Initialized pvr 1.14.3699939 20110701 on minor 0
In v. 4.4 it is:
[ 1.876664] [drm] Initialized drm 1.1.0 20060810 [ 2.379288] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [ 2.379289] [drm] No driver support for vblank timestamp query. [ 2.383661] [drm] Enabling DMM ywrap scrolling [ 2.455023] omapdrm omapdrm.0: fb0: omapdrm frame buffer device [ 2.492277] [drm] Initialized omapdrm 1.0.0 20110917 on minor 0 [ 15.747378] [drm] Initialized pvr 1.14.3699939 20110701 on minor 1
omapdrm isn't initialized.
CONFIG_DRM=y in the .config
What is the doubt?
