GMSL camera stuck

Hi,experts
I am using GMSL camera with xavier. The GMSL data is transmitted over 15m coax cables. Use v4l2-ctl to capture the image, it stucks after a while. But it works well with 5m or shorter cables.

I don’t think will problem can fix by software.

Hi, ShaneCCC
The camera works well in TDA4 platform.
When this issue happens, the trace log shows CHANSEL_FAULT. Is it possible to disable CHANSEL_FAULT to capture frames?

Not sure if it is caused by long cable. You can probe the signal waveform to check if SI is as requested. Otherwise if SI is bad, this can not be achieved by SW.

It’s HW problems.
