hi, every one
i wan tto port a u-boot on a 4kec fpga board( cpu speed just 12M now)
i used the sdram with no cache on.
i add some printf in board_init_f and board_init_r
the printf in board_init_f will output every time,the printf in
board_init_r sometimes output,sometimes not
if i use bdi2000 to debug, it printf correct in board_init_r and hang
at function devices_init().
i have read the manuel at eldk's page, which said that reason for hang
after relocate_code maybe caused by sdram access by cache.but i do not
use the cache
does there any other reason maybe cause that?
