My Jetson came with R19.3 pre-installed. I’ve installed from the JetPackTK1-1.0, and reflashed after setting ODMDATA=0x6209C000.
I will now be rolling back to R19.3 (and hope to keep the rest of JetPack installed), as I am also hitting the nvapv firmware bug mentioned in this thread → portaudio causes kernel crash in L4T_R21.1 and L4T_R21.2 - Jetson TK1 - NVIDIA Developer Forums
