Based on a HK1 RBOX X4 (S905X4) I'm "playing" with mainline support for SC2.
This Android TV box is based on the ah212 reference board according to uboot prompt.
Most relevant things are working meanwhile (eMMC, SD, SDIO/WiFi, USB2/3, ethernet)
and I can use the system headless.
However I'm struggling with panfrost/hdmi. With SC2 a lot of vpu registers have been
relocated (e.g. all hhi regs), even though the functionality seems to be more or less
compatible to G12A. I had to extend the timeout for HDMI PLL locking.
After having sorted out such things:
- dmesg for panfrost and hdmi looks normal
- monitor detects signal and OSD shows correct resolution (1920x1080@60 in my case).
I'd interpret this in a way that the clock/divider/mux registers are programmed correctly.
However I just get a solid green screen. From what I've read this can be caused
by a failing hdmi handshake. Not being an expert in DRM/HDMI any hint on where to start
debugging would be appreciated.
