我试过了,还是不行呢.
我的配置:redhat9.0 skyeye0.9.8 uclinux20030305
在uclinux配置的时候选上了 nfs nfsv3 busybox 里也选上了mount 的命令
主机的nfs测试过可以用的.
skyeye.conf如下
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

怎么让uclinux启动时的文件系统就是可读写的呢?是在skyeye可以配置的还是要在uclinux里面配置的呢?
是不是一定要用nfs做跟文件系统skyeye才能mount呢? |
