Hi all,

I just want to disable relocation because i want to run the uboot from ram and debug(BDI 2000).

I tried like this i changed the TEXT_BASE to 0x1900000 (my ram is 32 Mb)

But my u-boot code is failing to compile (I am using ELDK)

please anybody help me

Best Regards, Arun

Hi,

After doing all the initializations (i.e) serail_init,init_baudrate etc.., finally it reaches to relocate_code(addr_sp,id,addr) in the board_init_f() function in the board.c file (lib_ppc\board.c) ppc4xx. what it does? which part of the code or data copies from flash to the ram?

The whole u-boot image is copied from the flash to the ram.This is done after the board_init_f function initialises all the required controllers.The relocation code is present in cpu/<your_cpu>/start.S

...

Is this required while I am running from the SDRAM? what part of the code I can skip in the relocate_code function? If running from the flash what should i do?

It is required to run from the SDRAM.Since the entire image is copied as is, the complete code needs to be copied.Why would you want to tamper with it?
