Why is the system of Xavier platform stuck in the following interface ?

HDMI display interface has been stuck here, the UART and USB did not respond !!

SDK version: R32.1

sudo ./flash.sh jetson-xavier mmcblk0p1

Please move to latest release. R32.1 is a little out-of-date.

Now the old version of the driver porting to the new version caused an exception,
so want to brush back to the old version for verification

If I swipe a new version, then swipe an old version of the SDK, is it not compatible?
