求斑竹指点怎样调试2.6 for xsale的vmlinux

metop

skyeye-0.8.6+linux 2.6.8 for lubbock

linux采用如下方法编译的
make ARCH=arm lubbock_defconfig
make ARCH=arm menuconfig
make ARCH=arm CROSS_COMPILE=/path/to/arm-linux- zImage

可以采用如下skyeye.conf运行zImage
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=./arch/arm/boot/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

但是如果我想要按照源代码单步执行内核，是不是只能运行vmlinux文件呢？zImage中的调试信息已经都被strip掉了，我修改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=0x01000000
mem_bank: map=M, type=RW, addr=0xa1000000, size=0x00800000, file=./initrd4M.img
mem_bank: map=M, type=RW, addr=0xa1800000, size=0x02800000
然后运行：
#skyeye vmlinux
...

该怎么办呢？大家帮个忙吧，谢谢
