问 void SysSetInterrupt(REG32 vector, void (*handler)())
{
InterruptHandlers[vector] = handler;

}
我将三星snds100开发板上的程序(其中包含串口、HDLC、中断等)移植到我的 S3C4510B板子上，目前在板子上用仿真器仿真,程序跑起来正常(含串口、HDLC、中断等),但我不知道如何把此程序装载到我的板子上让其掉电不丢失，我使用的init.s程序如下，哪位大侠伸伸手、帮帮
忙，谢谢了。都折腾7天了没出来，我都快急疯了。


使用此init.s程序,不能正常启动。

LDR r0, =0x3FF0000
LDR r1, =0x83FFFF90 ; SetValue = 0x83FFFF91
STR r1, [r0] ; Cache,WB disable
; Start_addr = 0x3FF00000

;ROM and RAM Configuration(Multiple Load and Store)

LDR r0, =SystemInitDataSDRAM
LDMIA r0, {r1-r12}
LDR r0, =0x3FF0000 + 0x3010 ; ROMCntr Offset : 0x3010
STMIA r0, {r1-r12}


还有我不明白的是此程序上电只做了一次映像，没做重映像，不知为何？


我用Twentyone（xuzhouhe@hotmail.com）大侠告诉的方法写一启动代码也不好用。
