Unable to boot Debian 12.11 v6.15 image

I’m trying to move my beaglebone black from 11.11 to 12.11. I made a microsd card with the am335x-debian-12.11-base-vscode-v6.15-armhf-2025-06-30-4gb image. Included is a log of booting up. Also a copy of the v11.11 dmesg.

beaglebone.log (91.9 KB)
debian_v11_dmesg.txt (31.8 KB)

This is fun to see!
