然后系统挂起没有反应了.
不知改怎么办？求教高手！！ 0: 1400000-13FFFFF (RO)
13FFFFF不对,
检查一下你的kernel目录下的.config,
FLASH_MEM_BASE=01400000
FLASH_SIZE=00400000
另外skyeye.conf也要匹配 请问一下是那个kernel目录啊？
在/uClinux-dist/linux-2.4.x/kernel？下面没有这个.config文件。
另skyeey.conf怎么匹配啊,
请帮个忙，都配置了几天，还是没有启动uclinux,郁闷中.... 解决了
用以下skyeye.conf
cpu: arm7tdmi
mach: at91
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R,addr=0x01400000, size=0x00400000, file=./images/romfs.img
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
不知道为什么昨天不行，今天OK了，什么也没做啊 昨天设置的是
mem_bank: map=M, type=RW, addr=0x01300000, size=0x00100000,file=images/romfs.img
与你这次的设置不同。 上面的兄弟对skyeye.conf很熟了，谢谢了!
