skyeye lubbock仿真无法设置断点

zlx

我用skyeye 仿真lubbock，但是无法设置断点调试
skyeye.conf 如下

cpu: xscale
mach: pxa_lubbock
mem_bank: map=I, type=RW, addr=0x40000000, size=0x0c000000
mem_bank: map=M, type=RW, addr=0xa0000000, size=0x00200000
mem_bank: map=M, type=RW, addr=0xa0200000, size=0x00100000, file=zImage, boot=yes
mem_bank: map=M, type=RW, addr=0xa0300000, size=0x00d00000
mem_bank: map=M, type=RW, addr=0xa1000000, size=0x00800000, file=./initrd4M.img
mem_bank: map=M, type=RW, addr=0xa1800000, size=0x02800000

运行skyeye

经调试发现仿真lubbock的linux设置断点需要将vmlinux转成bin格式加载
同时还需要load vmlinux。
设置断点时也很奇怪，需要同时设置两个断点才会中断。
(SkyEye) inf breakpoints
Num Type           Disp Enb Address    What
1   breakpoint     keep y   0xc0008658 in start_kernel at init/main.c:499
2   breakpoint     keep y   0xa0008658
                                         ^^^^^^^^这个断点是上一个断点的实地址

(SkyEye) r
Starting program: /home/znanth/course/xscale-dev/skyeyetest/vmlinux

Breakpoint 1, start_kernel () at init/main.c:499
如果只设置断点1skyeye不会产生中断
而如果只设断点2会产生中断，但是却无法继续运行。
当设置了两个中断时，应该是中断2使skyeye停下来，但是实际上察看中断信息却是breakpoint1 hit 1次
(SkyEye) info breakpoints
Num Type           Disp Enb Address    What
1   breakpoint     keep y   0xc0008658 in start_kernel at init/main.c:499
        breakpoint already hit 1 time
2   breakpoint     keep y   0xa0008658
因此怀疑skeye在中断处理时没有根据mmu的情况处理虚地址与实地址的转换。
