关于skyeye仿真2410的问题
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, , #4
str r4, , #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！ > 能够进入shell，但是仅是进入shell了。没有建立起linux环境。
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
回复 #1 lucky_ma 的帖子
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
