SPI on Jetpack 4.6.3

[prapor]

Hello,
SPI doesn’t work on Jetson Nano 4GB dev board with Jetpack 4.6.3

steps to repeat:

1. install Jackpack 4.6.3 via SDKmanager
2. enable SPI via /opt/nvidia/jetson-io/jetson-io.py
3. reboot
4. modprobe spidev
5. sudo ./spidev_test -D /dev/spidev0.0 -g32 -s 11000000 -p0 -zzz
   return (TEST FAILED ):

The same steps, but Jackpack 4.6.2 (and 4.6.1) works fine, return (TEST PASSED):
