There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Please share the complete bootloader logs for reference.
Or you can try to do the reflash you Xavier NX device again to know if can recover it.

If you’re not able to enter forced-recovery mode to re-flash the target, then this might be hardware issue, the power led should stay enabled if the power supply connected.
