[U-Boot-Users] I can't debug U-BOOT after relocation in ram

[Andre Puschmann <andre.puschmann@stud.tu-ilmenau.de>]

Hey,
another problem can be that you have a wrong address offset for your gdb
after relocation?
i also had problems with the address offset while using this faq.
try to enable uboot debug and have a look at the relocation address that
is printed out or try using gdb to find out the right address before
u-boot relocates itself to ram.


Regards,

Andre
