/dev/video[01]?

I don’t see anything wrong with the dts.

Unfortunately, I can’t help much, my whole setup is based on 5.10 due to using libmali, i can’t just switch kernel as you can with Armbian.

What i know is these guys are actively working on the rockchip media and perhaps they have up-to-date documentation (or they can talk to rockchip directly) and can give you some inside information.

I think you are right.
If you want to debug the kernel: (https://github.com/armbian/linux-rockchip/blob/rk-6.1-rkr1/drivers/media/platform/rockchip/cif/capture.c#L6405)

I will follow the conversation…

Thanks. Yes amazingfate usually answers on discord armbian-rockchip channel. I’ll try to contact him there too.

Update: since this CIF and ISP driver/sdk software is Rockchips work their staff should be most suited for solving it. I sent an email to someone there.
