two DTS, one for PPS-GPIO, and one for W1-GPIO, test successful . Maybe someone can intergrate into kernel source tree sun50i-h616-pps-gpio.dts sun50i-h616-w1-gpio.dts

Try this simple DTS file made by myself. sun50i-h616-pps-gpio.dtbo sun50i-h616-pps-gpio.dts

The debugger provided a few clues, but what ended up working was I flashed it to the eMMC.

@jock Hi, thanks for your work about ffmpeg-v4l2request. Your ffmpeg-v4l2request is 5.1.4, Debian bookworm's ffmpeg now is 5.1.6. Would you like to share your patches about v4l2request support for ffmpeg so I could build 5.1.6 myself, thank you.

Thanks, although the aic8800_fdrv module fails modprobe due to no device found error, Bluetooth module loads, but it was same when I compiled the module myself a month ago. It is fine for what it is though, maybe it will work without accessories in the future
