jetson Orin NX platform, JetPack version is Jetson Linux 36.4 (part of JetPack 6.1), Two cameras using mipi cables directly into the jetson:
After executing sudo insmod iimx415.ko , it can be observed that I2C communication functions properly, the driver binds to the sensor successfully, and the V4L2 sub-device registers without issues.

However, after entering the data collection command, the Jetson loses connection and then forcefully restarts (hence functions like set_mode and start_stream are not invoked).

Since the Jetson device forcefully restarts, it is impossible to capture the tracelog.
