When running the R24.2.3, and the config the 2nd video output as eDP,
TX1 outputs the eDP signal properly according to the read EDID.
But after 1 or 2 dettach and then attach the eDP cable,
TX1 may output the eDP in 640x480 or 720x480 or …etc randomly.
After investigation, we found that the function “static int tegra_fb_set_par(struct fb_info *info)” in fb.c, its parameters carries the wrong contents,
such as 640x480 or 720x480 …etc randomly.
Also the HDMI-audio-out is shut-down. I have to restart the media player to make the HDMI-audio-out enabled.
(headset output works normally all the time.)
It seems its the most top interface in kernel source.
Can somebody help to fix this?
