CONFIG_SYS_INIT_RAM_SIZE and CONFIG_SYS_INIT_SP_ADDR. Can this cause this problem?
SYS_INIT_SP_ADDR is required, if you see 'DRAM: ...' output it is likely to be a correct value for you. I guess your gd_t parameters for SDRAM size are not correct which leads to a wrong relocation address and therefore relocate_code() fails.
Yes, I've fixed gd_t parameter but the result hasn't changed.
Ok ... can you debug the board_init_f/relocate_code/board_init_r functions? Where is your relocate_code() destination address (it is calculated in board_init_f())? Is relocate_code() reached? Does the fixup loop's run? (don't forget to reload symbol file as described in doc/README.arm-relocation) Is board_init_r() reached? ...
All behaviour described so far relates to at91rm9200dk board.
at91rm9200dk uses the deprecated arm920t/at91rm9200 stuff and is known to be broken currently! The arm920t/at91rm9200 code will be deleted in near future! (and so at91rm9200dk board, if you have one handy please try to get it working with arm920t/at91 files). If your board uses arm920t/at91rm9200 configuration please convert it to arm920t/at91 ASAP!
You mentioned trying at91rm9200ek board, so I switched to it, but I have problems with with compilation when data flash memory is used (I need it to store environment settings).
Sorry, I can not help here cause I didn't get dataflash working with at91rm9200ek yet.
So I tried not to store environment settings by defining CONFIG_ENV_IS_IN_NOWHERE and comment out all data flash configs, but I end up with multiple undefined references (to flash, spi and dataflash).
How did you make your board to run only in RAM omitting flash configuration?
Well I own an at91rm9200ek and use the at91rm9200ek_ram_config to build (is mainline). The NOR flash booting is currently broken but getting this working is my next target.
Dataflash for at91 targets in principle is currently somewhat broken/unreliable/defective API (there was a discussion these days, search the list).
