Hi, guys! Will you assist me in integrating a screen AUO P370IVN02.0 (lvds 1920x540) with
an iMX6?
The data sheet AUO P370IVN02.0
buildroot-2016.11 kernel 4.1.15-2.0.0
I can’t get the correct image on the screen:
It just seems that one of the lvds channels is horizontally indented…So, there is the effect of pixel doubling. What could you advise me to do in this situation? Thank you so much for your assistance!
I applied 3.3V to the 7th port of the screen (i.e. the mode NS)
The 5th port is GND (i.e. the mode 8BIT)
