In u-boot-2009.08/cpu/arm920t/start.S, the instruction of line 158 is "ldr r1, =0x3ff", but the effective bits in INTSUBMSK register of S3C2410 are [10...0]. So I think "0x3ff" is not right. The right value should be "0x7ff". ___________________________________________________________ 好玩贺卡等你发,邮箱贺卡全新上线! http://card.mail.cn.yahoo.com/
