Interesting! Have you tried plugging in a serial debug cable and looking at dmesg?
Our older board got to this point, but we didn’t see anything on screen. We kinda assumed it was due to the A02 being incompatible. We had hoped the B01 was compatible with the TX2 NX.
Here is a how to link for using the serial cable:
