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?

thanks !

regards
