Kelvie Wong got a reaction from kostprof21 in HDMI doesn't work for radxa-zero 3 on "current" and "edge", but works on "vendor" (for the 4GB version)The patch doesn't build against rockchip64 6.12 -- and looking at the patch it doesn't affect the RK35XX series at all.
To port it, I think I need the max_prate constants for the RK3566 (is this in clk_rk3568.c? or some other file, there isn't a clk_rk3566.c)
I think the datasheet (https://www.boardcon.com/download/Rockchip_RK3566_Datasheet_V1.1.pdf) says it's 600MHz for HDMI

Kelvie Wong got a reaction from laibsch in HDMI doesn't work for radxa-zero 3 on "current" and "edge", but works on "vendor" (for the 4GB version)So I have two boards, and two images, both built with armbian-build. I built `current` on March 24th 2025 and HDMI and everything works great
I built one this week and there is no HDMI output.

On the non-working one, I've tried both the same kernel version (6.12.20) as well as the most recent `current` (6.12.21), and edge (6.14.1).
Buildling a vendor image on bookworm works fine. Given I have two systems where one works and one doesn't, what can I check between them (deb package versions maybe? DTB files?) to help debug this?
