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

Hello,
I try to debug U-boot in flash with GDB version 6.5 + BDI 2000.
I have followed topic about RAM relocation from DENX web.
but when U-BOOT is relocated in Ram, I cant stop it at board_init_r().
My custom Board configuration is:
Hardware :
---------------
-MPC875,
-64MB (Top address 0x4000000)
-2MB flash
Software :
---------------
U-BOOT 1.4.4 in flash at 0xFE000000
Relocation address (read in R5 register) is 0x3FB00000
DER register value is 0x2006000F
Thank you for your reply.

Hey Patrick, if you can't stop in board_init_r() than most properly there is something wrong with your sdram initialization. Do you have any serial output?

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.
