各位大大~ 我成功了..關鍵在於fxxkboss大大所說的..要將machine number設定到r1暫存器.. 我抓Android kernel 2.6.25回來自己build成zImage.. 然後在arch/arm/tools/mach-types裡面找到了一行 s3c2440 ARCH_S3C2440 S3C2440 362 接著將之前的cp_mem()改寫成: void cp_mem() { unsigned long *dst; unsigned long *src; int (*f)(void *); dst=(unsigned long *)0x30030000; src=(unsigned long *)0x10000; while (src < (unsigned long *)0x200000) { *dst = *src; dst++; src++; } cleanup_before_linux(); putstr("image ready, any key continue\n"); getc(); f=(int *)0x30030000; asm("mov r0, #0x0"); asm("ldr r1, =0x16A");//r1 = 362 f(0); } 把start_vector.bin燒到0x0..把zImage燒到0x10000.. 就出現了以下的開機畫面..
