Did you ever make progress on this project?

@Harleyyyu See this thread; hardware video decoding works fine with mainline kernel and does not need vendor MPP. Debian Trixie although has a "broken" mpv that won't work, better stay with Bookworm

Already got answer from upstream programmer❣️ That kernel thread in RPMSG was removed due to excessive CPU usage. I got the impression that this is true: edge:desktop is nearly un-usable. Also they say: there is kernel 6.19 from upstream/upstream in the make. For now, I'm reverting HDMI audio (and all other rCPU funcs) for edge. LG // Sven-Ola

I'm awaiting delivery of a new extruder heater/nozzle and it seems the wifi is reluctant to connect. Previously, the wifi would not connect until a calibration had been performed and it will not calibrate due to the extruder heater failing. I did upload the Sovol SV06 Ace mainboard schmatic to the O.P. but it is for board version 1.1. Hopefully I can connect, ssh in and get the *dtb file once the nozzel is replaced. Then cross check the *.dtb with the schematic. The new board,v1.2, likely uses the same Broadcom BCM43430 that Sovol Kipper Screen v1.2 uses. It may also have an additional fan socket. For future reader/search hits, you actually have to use radxa linux upgrade_tool. It will be a couple of days before I can follow up.
