[请问] No filesystem could mount root, tried: cramfs的问题
我编译好内核，搭好文件系统烧到板子里，启动后，最后出现下面问题uncorrectable error : <3>end_request: I/O error, dev mtdblock2, sector 256
isofs_fill_super: bread failed, dev=mtdblock2, iso_blknum=64, block=128
List of all partitions:
1f00 256 mtdblock0 (driver?)
1f01 2048 mtdblock1 (driver?)
1f02 257536 mtdblock2 (driver?)
No filesystem could mount root, tried:cramfs vfat msdos iso9660 romfs
