Can the OPI5 be Configured to Run LCNC?

anyway I appreciate the effort. Thank you.

Found a possible cause, which might explain why nvme works on OPI5-plus and sata on OPI5, but nvme doesn't on OPI5:

Here the deb where I removed the revert:

Now is working. Thank you.

I tried to activate the spi and the usart in armbian-config/Toggle hardware configuration, but the peripherals don't appear there.

Possibly the names don't match since you copied the folder with the dtb files and overlays.
It might be easier to add them manually in /boot/armbiEnv.txt
There you'll see "overlay_prefix=" and "overlays=", these should match with the filenames in /boot/dtb/rockchip/overlay/
So for example rk3588-uart6-m1.dtbo and rk3588-spi4-m1-cs0-spidev.dtbo it will be:
overlay_prefix=rk3588
overlays= uart6-m1 spi4-m1-cs0-spidev

And make sure that the overlays don't overlap each other, so don't activate therm all.

I tried this but I had a conflict in the uarts declarations. I solved it.
Where can I read how the realtime rtapi_app process is assigned to core 7?
How can I assign realtime priority to a process that uses the uart?
