just as a statistics/stability report: the DTB with the NPU works very well. Uptime of the device is already a week, it's running armbian and immich on it. While immich lags sometimes because the board can be weak for video processing, but in general it already processed ~20k images with OCR and face detection based on RKNN. I consider it pretty good results.

I'm struggling to get the Pi Camera 3/IMX708 detected by the Zero 2W. It's an IMX708 sensor, and that is correctly showing in dmesg, but the V4L2 devices (/dev/video0, /dev/video1) for the camera are not set up. All the normal encoder devices are fine. I'm using a custom build but it's essentially minimal (and no desktop) current with trixie and no extensions, following the standard command for building an image. The dmesg log reads as follows: [ 10.719672] imx708 10-001a: camera module ID 0x0302 [ 10.719876] imx708 10-001a: ctrl(id:0x9f0902,val:0x232aaf80) is not handled [ 10.722275] imx708 10-001a: ctrl(id:0x9e0902,val:0x2b20) is not handled But I don't think this is problematic, as stock Raspbian shows precisely the same log messages, and it does correctly set up the devices. I've added the overlay and turned off (or tried to) the camera auto detection, but the imx708 messages were being logged even before I added the overlay, so I am not sure it was needed. In any event, nothing changed. Any thoughts on ways to get this up and running?

never heard of that kernel before

I have wifi and it worked without building or installing anything. During the first boot I was asked if I would like to use wifi, I saw the list of SSIDs, but I was unable to connect. I used nmcli and I'm connected now. dkms status outputs: bcmdhd-spacemit-sdio/101.10.591.84.37-4, 6.18.36-current-spacemit, riscv64: installed Update: It boots from eMMC
