Hi Klaus,

Thanks for your detailed response. More below.

Hmm. Looks like things go wrong in u-boot SPL, before entering u-boot
proper, but it's not entirely clear. You could try to isolate the
issue by first flashing the freedom-u-sdk image, and replacing the
u-boots one at a time with the versions from my port.

So:
 1. dd entire freedom-u-sdk image to SD
 2. delete linux and msdos partition
 3. Verify that board boots to u-boot 2020.07 (non SPL)
 4. dd u-boot.itb from my port to
!2e54b353-1271-4842-806f-e436d6af6985 partition
 5. Check whether it boot to u-boot 2020.10 (non SPL)
 6. If it does, dd u-boot-spl.bin from my port to
!5b193300-fc78-40cd-8002-e86c45580b47
 7. See if you receive the above unhandled exception

Before we try booting to freebsd this should help us narrow down where
u-boot is going wrong. Please give this a try when you have a chance
and let me know the result.

Usually this indicates that the backup GPT header can't be found, and
is harmless. However, I did find a small issue with the config that
generates the GENERICSD image, and I will have to generate a new one.
