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,
