In the past, I have bypassed the relocation code so I can run u-boot from where it was linked;
[Leonid] You just commented out relocation function? Can you send me your change if you have saved one to try?
It's pretty trivial stuff. I don't have a patch for you, but go into start.S and look for the relocate_code symbol. All the stuff between there and clear_bss is strictly relocation code. I just exported the clear_bss symbol and called it from board_init_f! (but I had to fix up some of the calling parameters first. *HUGE* hack, but it worked. :) I don't do this any more though.
(hint: add #define DEBUG above the includes in board.c)
BTW, Leonid; You want to use ppc_4xx, not ppc_4xxFP. I don't know about the uartlite driver.
[Leonid] I use ppc_4xx, now I'm running Kegel cross tool - all the same.
BTW, could you manage source level debug for you target? I download elf file via XMD and then try to connect GDB remotely, but addresses GDB show have nothing to do with real address (u-boot is located on 0x01f00000):
You need to load the symbol table at an offset. I think you use the add-symbol-file command. The details are in the u-boot documentation somewhere.
