can not capture frame from 1920x1200, BA10 sensor under 500Mbps rate on IMX93.

I can bring up ar0144 with 1280x800, BA10 &BA12 format with rate lower than 500Mbps, now when I try bringing up another sensor which has resolution 1920x1200, 30fps, rate of 500Mbps, BA10 format, I can't bring up it. log is:

Could you give some guide on it? Thanks.

what's your new sensor? the new sensor send the same BA10 pattern format as ar0144? I didn't find any error in your logfile, you can compare your new camera with ar10144, compare the registers to find the root cause

@joanxie

Thanks for the reply. The new sensor is ar0235. After adding some patch from Zoey it can work now. It's main reason is timing between CSI receiver and sensor output. If CSI receiver start the MIPI receiving earlier then sensor output issue can be fixed.

ok, got it, refer to you description, the root cause is that your camera uses continuous clock mode, mipi csi receiver require the connected camera to work in the LP state before enabling the Rx DPHY

Understood, thanks very much for the explanation.
