NX Jetspack ：Jetpack 4.4 DP。
I use LT6911,it’s a chip make HDMI to CSI。If i give HDMI signal,CSI can have singal out.If i do not give HDMI,CSI will always high level.
The problem is，if i do not give HDMI,driver may cause kernel problem.And i can not close /dev/video0, This problem only happen in Jetson nx. Jetson nano have no such problem,in jetson nano,i can open /dev/video0,than give CSI singal.Can Restore display。
Can give some advice.If do not give CSI signal,driver can wait signal without causing kernel panic.
