Just a quick heads up.
Tested Rockchip dev build 20230805144010-e014594-rk3568.
Changed DTB to matching one for an ODROID M1. Booted into it, made some tests.
Works:
- Display output ( 4k resol. w/ LG 34WK95U-W over HDMI w/ sound output, Full-HD with Panasonic 2015 TV)
- CEC control, Panasonic 2015 TV
- Sound output over HDMI
- Wired networking
Does not work:
- Accelerated video playback.
Overall this looks not too bad.
