小弟在nios2上移植了uclinux1.4.0内核和根文件系统，flash（32M）分区为5块：在/dev建立了“@mtdblock0,b,31,0”,“@mtdblock1,b,31,1”,“@mtdblock2,b,31,2”,“@mtdblock3,b,31,3”,“@mtdblock4,b,31,4”对应于flash的5个分区

接下来对flash的分区2格式化为ext2格式时出现了问题（小弟用的是博创的ar2000开发箱）,如下：

#mount -n -t proc /proc proc

#cat /proc/mtd

dev: size erasesize name

mtd0: 00600000 00020000 "romfs/jffs2"

mtd1: 00400000 00020000 "loader/kernel"

mtd2: 01200000 00020000 "user space"

mtd3: 00200000 00020000 "user configuration"

mtd4: 00200000 00020000 "safe configuration"

#mke2fs /dev/mtdblock2

mke2fs 1.25 (20-set-2001)
