Universal Cape not working on BeagleBone Black with Kernel 6.1

[sans-ltd]

We tried to build a custom image with the image builder for our project. Our configuration was forked from the debian minimal config.
Since we rely on pin-config and the universal cape, we uncommented

enable_uboot_cape_universal=1

in /boot/uEnv.txt.

After a reboot, the following issue appeared on the serial console:

U-Boot 2022.04-gbaca7b46 (Jan 15 2024 - 19:59:28 +0000)

After checking the file system, it became clear that /boot/dtbs/6.1.83-ti-r36/am335x-boneblack-uboot-univ.dtb is missing.

In the meantime we switched back to Kernel 5.10. Here it works as expected.

Please continue to stick with 5.10-ti, i think we figured out what's destroying eMMC's in 6.1.x, but i still need 4 weeks to verify.
