can anybody give me some hints how to use an eDP-panel with the EDGE-V and Android?
I found this document http://rockchip.wikidot.com/edp but have problems to apply it for my case.
Without modifying any files the eDP display stays black and the directory “/sys/class/drm/card0-eDP-1” is not created. What exactly would I need to do to get it running?
rk3399-evb-rev3-android-edp.dts rk3399-evb-rev3-android-mipi-edp.dts(mipi-panel+edp-panel)
You can refer to the above two DTS to configure, and the following documentation:
The documentation is very difficult to follow without major knowledge (and without knowing Chinese). Would I need to copy relevant parts into rk3399-khadas-edge-android.dts and then recompile the kernel? Do you have any more detailed information about this? Thanks a lot!
Yes, replace the relevant screen nodes with rk3399-khadas-edge-android.dts and then recompile the kernel.
If you don’t know Chinese, you can translate it by Google.
A general question about eDP: from the specs it looks like the pinout between the panel and the EDGE-V does not match. The panel follows the specs for eDP 1.2. After all is an eDP 1.2 panel compatible with eDP 1.3 (EDGE-V)? If not can you recommend displays which are compatible? I am looking for a 13.3’’ one with 1080p but can only find displays where the pinout is different.
