Re: [microblaze-uclinux] Please, I need your help about petalinux and the U-boot bootloader
Hello,
I have the exact same problem. I have verified that the address mappings
are correct. The board boots with the pre-built reference design, but it
hangs when I try to boot with a reference design I compiled myself after
the message "FS-BOOT: Booting image...". Any further ideas why this
happens?
Regards,
Kristoffer Hedberg
