How to use eDP?


so there is zero documentation on how to use the eDP Interface [under linux] in the Wiki.

After some googling it seems like i need to mess with the DTS-files to the kernel to make it work. But that only resulted in a blackscreen/noboot sofar… Since i had to make a custom PCB for my eDP display, i also don’t know if my PCB is right, so i need a way to debug that, too…

Any advice?

Some notes from the schematic:

Backlight Enable GPIO: LCD1_BKLT_EN [Alias?]
Backlight PWM: PWM0
LCD_VDD seems to be switched by: GPIO4_D3_1V8 [GPIO10]


So this is where i’m currently at, sadly it’s not booting yet:
