Faulty DTB for GPU & probably other issues for the Rock 4C+
krankes_etwas posted a topic in Rockchip
Hey guys, First of all I would like to let you know that the default DTB has an issue, the GPU status is disabled by default. I've changed this & now my GPU is detected & working fine so far. (Armbian Jammy current) But I'm also facing some other Issues.... not all USB Ports are working, just 2-3 & the working ports sometime are randomly switching after a reboot. Bluetooth isn't working at all I guess these Issues are also related to the dtb file because I didn't find any entries for BT in the DTB. I also tried the other DTB file: rk3399-rock-4c-plus but I dont have any video output with it but there I found some entries related to BT (default is rk3399-rock-pi-4c-plus) I also noticed I didn't get any Video output from the latest sid & edge, but Kernel was loaded. Then I forced the Resolution in the Armbian.env to 1080p, with that settings I got vidio ouput during the boot time & CLI. But as soon the Xserver has started I got no more Video output or I got a weird/broken video output. Probably its an gpu driver Issue.... I should also mention that my GPU isn't working & detected in Debian too (all kernels) But as I understood right the gpu isn't deactivated in the DTB file from Debian, but except the gpu everythings is working. Here are the Logs & DTS files Any ideas how to solve this ? -
Could anyone help me to enable display with Armbian? I just can’t figure out why it doesn’t work. I don’t see the backlight turning on either. What do I have to change? I have tru to add a custom dts on kernel but don't work
