When I turned on my camera on top of jetson 5.0.2, the following situation appeared.
Attached my dmesg error message.
dmesg.txt (3.0 KB)
Hope you can help me tell me where the error came out.
Did you try v4l2-ctl to verify the sensor driver and HW first.
v4l2-ctl -c bypass_mode=0 --stream-mmap
Yes, I have tried v4l2-ctl. I have 8 cameras, 4 of which can be used. The above error will occur.
I wonder if there is a problem with my device configuration.

Modify the serdes_pix_clk_hz to 374000000 to try
Thank you. I tried your method. But it still happened before.

Looks like the communicate with TI933 failed.
Thank you for your help. Can you prompt me where I caused the problem?
Consult with HW to confirm the Power Down/Rest PINs status.
I checked the relevant hardware. Do you have any other valuable suggestions for me?
