各位大大~
我成功了..关键在於fxxkboss大大所说的..要将machine number设定到r1暂存器..
我抓Android kernel 2.6.25回来自己build成zImage..
然後在arch/arm/tools/mach-types里面找到了一行
s3c2440 ARCH_S3C2440 S3C2440 362
接着将之前的cp_mem()改写成:
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烧到0x0..把zImage烧到0x10000..
就出现了以下的开机画面..
Hello
Any key to continue
Yes
image ready, any key continue
