A603 Carrier Board Issues (Flashing and USB)

Hello –
Several months ago I was able to successfully flash my Orin NX on an A603 to JP 5.1.2 using the steps and files in the wiki.

This week I tried to follow the steps in the wiki (on the same computer, just a fresh download) and flashing fails. On the host side, it times out with “waiting for target to boot up” and the device side serial logs end with:

Can you help me figure out what is going on? For what its worth, I’m able to flash to jetpack 6 using the instructions in the wiki but I need jetpack 5.1.2 for my project.
