We are using Zynq UltrasScale+ MPSOC and gstreamer to develop our h265
encoding application. It works fine in most cases. But if we disconnect HDMI
cable while encoding under ultralow latency mode(set caps "memory:XLNXLL"),
kernel print "Mcu trace: Channel has hang" and we can't start encode again.
How to fix it?

The "Mcu trace: Channel has hang" message might be due to camera unconnected, can you observe the same message in the other VCU latency mode?

It's caused by HDMI cable unconnected. I think it's same meaning to your "camera unconnected".
The message is only displayed under ultralow latency mode.
