关于skyeye仿真2410的问题

lucky_ma

这些日子我在用skyeye来仿真s3c2410，但是一到memorysetup的代码就会出现问题，我用gdb一步一步跟踪调试发现问题处在“mov   pc, lr”上，请版主看下面的代码，当下面的循环执行一段时间以后r1，和r3的内容相等但是    “cmp     r1, r3”并没有修改cpsr的相应标志位，我试了多个程序都不行，不知道为什么会这样？

mov     r1, #MEM_CTL_BASE
    adrl    r2, mem_cfg_val
    add     r3, r1, #13*4
1:
    @ write initial values to registers
    ldr     r4, [r2], #4
    str     r4, [r1], #4
    cmp     r1, r3
    bne     1b
    mov     pc, lr
我用的skyeye版本是1.2配置如下

如果把linuxrc改成脚本
#!/bin/sh
/etc/init.d/rcS
能够进入shell，但是仅是进入shell了。没有建立起linux环境。
急盼帮助！非常感谢！

ksh

what do you mean? I cannot understand. I think if you can see shell and execute some shell command. That means you are successful for run linux on SkyEye

请问你是怎么调试的？
我执行stepi怎么老是显示：
can't send signals to this remote system, SIGHUP not sent
并且除了continue这个命令以外，其它的调试命令都不生效，比如我打：
b *0x00000005
c
我想让它在它并不停下来

怎么进行调试啊

把这行注释掉就能调试了
