i tested it on mighty ... did you have any mmc errors maybe which might have resulted in the btrfs ro you saw?

hexdump0815: So there is a script for merging configs, nice! Thanks for the info.

hexdump0815: I just checked the bullseye sdcard again and mount still shows '/dev/mmcblk1p4 on / type btrfs (ro, ...)'. If I run 'mount -o remount,rw /' it fails with 'mount: /: cannot remount /dev/mmcblk1p4 read-write, is write-protected'

hexdump0815: Ok, I see the following in dmesg 'mmcblk1: mmc1:59b4 USD00 58.9 GiB (ro)', so for some reason when the drive detects the card it thinks it is read-only. It is a microSD so no physical lock switch like full size SD cards and/or adapters have. Not sure why the driver is flagging it read only...

hexdump0815: Found the problem. I had to change /boot/extlinux/extlinux.conf to add a menu entry for veyron-jerry that loads the jerry dtb and now everything is working. I am booted and logged into the desktop now
