[U-Boot-Users] Crash at the beginning of board_init_f

[Cai Frank-LFC008]

Hi,
 
I am porting a u-boot to a PPC8250 board. My code runs OK inside flash. Also
runs OK from SDRAM after the code relocation from flash to SDRAM for the
whole section of assemble code (in_ram). But it crashs at the beginning of
board_init_f ( The entry point of C code in SDRAM). It seems C environment
get crashed. What may cause this type of crash?
 
Can somebody provide some clue? Thanks,
 
Frank
