Hi Jan,

No additional trouble on here but just want to
confirm how you run your DE0 board.

1) Do you use a pure MMC boot? (no NOR Flash)
2) You follow old boot flash method write
aka placing "u-boot-with-spl.sfp" to A2.
The "boot+rootfs" partition can be empty or
not exist.
So simply the entire sdmmc just contains A2 and
u-boot can't pass SPL phase enter U-Boot phase?
Are you having this trouble in the first place?

Thanks,
Brian
