Hi Folks,

Per the instructions on the wiki, I've tried burning the rk3328-sd-debian-bullseye-core-5.15-arm64-20230529.img to an SD and booting it on a new R2C+. I've been able to successfully write and boot the eflasher version, but not this image.

I've used dd and win32diskimager and different SD cards to no avail. From the debug output it looks like the device is seeing the SDcard but is unable to read the kernel:
------------------

switch to partitions #0, OK
mmc0(part 0) is current device
Failed to mount ext2 filesystem...
** Unrecognized filesystem type **

Here's the debug output from the RC2+:

Has anyone burned and booted the debian core image successfully?
Any thoughts, pointers, etc. would be much appreciated.

Thanks,
