Hi @Hqnicolas I have same issue with booting from SD card for a board (RK3399) . Can you please share the u-boot image or guide to compile for that chip?

Hi all, I'm still working on video hwaccel with some progress. Can anyone provide a confirmed working ffmpeg command line for camera capture and hardware encoding? I dont care about the platform, either rockchip or anything else, no matter about kernel or arbiam version. Using v4l2request is the only requirement. I'm using either 7.1.1 with libreelec patches or @Kwiboo's fork. I know there are a bunch of threads here and elswhere in the web but most are outdated, dealing with vaapi or other stuff, but I want to stay on v4l2 which seems to be the future. Thanks! T.

I am not exactly sure what you are trying to do, but maybe the solaar or logiops package can help you achieve your goal.

@robertoj I use Nick's exact build (specify the branch) with bookworm. My tanix68 unit has a custom Hal and supplicant firmware, which I'm trying to integrate correctly, but LAN works just fine.
