Hello everyone,
Now I am debugging GMSL for camera, the driver run correctly. But when I using slave or trigger mode. The Orin NX show following error, it cannot recovery channel reset.
I was meeting similar problem before. and I solved it using follow patch.
Why does it cause it. Thank you.
BTW, Jetpack version
