Camera is unable to produce images, could you please help to see what the reason is?

After installing the above modified user, the problem still exists.

hello wxsrite,

although there’re signaling on the oscilloscope, VI tracing logs indicate its not receiving packets.
could you please see-also SerDes Pixel Clock section to review your serdes_pix_clk_hz property settings.
you may also check Module Device Tree section to double check gmsl-link device node.

BTW, please also have sanity test with v4l2-compliance test. thanks

Yes, you are right, after correcting these, the problem will be solved. Thank you so much!
