rk-6.1-rkr1: capturing video from IMX415 at MIPI/CSI not possible after ISP block, on rk3588s platform #298

Open enok71 opened 3 months ago

enok71 commented 3 months ago

On my rock 5a I can capture video from my IMX415 camera connected to the 4 lane CSI port if I capture data from /dev/video11 which is the raw video stream. But trying to get data from /dev/video[01] (mainpath/selfpath, after ISP) doesn't work. The reason seems to be related to the fact that device node /dev/v4l-subdev4 (rkcif-mipi-lvds2) is not created at boot. There seems to be no connection from rkcif to rkisp. All this worked in 5.10 but doesn't work in 6.1. I suspect it is an issue for all rk3588s platforms.

We have not officially released any Rockchip 6.1 SDK based image, so at this moment we won't take any support questions about it. We ourselves are still trying to figure this one out.

@Ken-Vamrs please double check if this is an issue on our system.

I appreciate your efforts. There is a message at boot about dependency cycle. Maybe that is a clue. Let me know if I can help.

@ivancheung2019 this issue is about the upcoming 6.1 kernel. There is no official 6.1 image at the moment.

It is still the wrong place to discuss this issue. You can create a forum post and tag @radxa in our forum to get technical support there.

Please also make sure you are using the Debian image (Ubuntu is unsupported) and performed system upgrade before you test the camera.
