nand-part不起作用！！！

noudle614

最近在进行nand flash分区时遇到的问题，发现nand-part不起作用了，即不能产生/dev/nanda /dev/nandb.
1.wget https://cubieboard.googlecode.co ... partition_image.bin
2.dd bs=4096 if=cubie_nand_uboot_partition_image.bin of=/dev/nand
3.nand-part
check partition table copy 1: mbr: version 0x00000100, magic softw311 OK
check partition table copy 2: mbr: version 0x00000100, magic softw311 OK
check partition table copy 3: mbr: version 0x00000100, magic softw311 OK
mbr: version 0x00000100, magic softw311
2 partitions
partition  1: class =         DISK, name =         boot, partition start =        8, partition size =     1016 user_type=0
partition  2: class =         DISK, name =         root, partition start =     1024, partition size =        0 user_type=0
check partition table copy 0: mbr: version 0x00000100, magic softw311 OK
check partition table copy 1: mbr: version 0x00000100, magic softw311 OK
check partition table copy 2: mbr: version 0x00000100, magic softw311 OK
check partition table copy 3: mbr: version 0x00000100, magic softw311 OK
mbr: version 0x00000100, magic softw311
2 partitions
partition  1: class =         DISK, name =         boot, partition start =        8, partition size =     1016 user_type=0
partition  2: class =         DISK, name =         root, partition start =     1024, partition size =        0 user_type=0
貌似已经分区了，此时reboot.....
在启动信息中出现：
[    1.233006] [NAND]nand driver, init.
[    1.242626] nand clk init end
[    1.259286] [NAND] nand gpio_request
[    1.266200] [NAND] nand driver version: 0x2 0x9
[    1.273346] nand interrupte register ok
[    1.299901] nand clk init end
[    1.375515]  nand: unknown partition table
[    1.382197] benn: nand probe enter
[    1.387749] [NAND]nand driver, ok.
完全进入后，查看/dev下根本没产生/dev/nanda和nandb，
再nand-part一下出现的跟上面的一样，有2个分区，无解了！看别人都是写入cubie_nand_uboot_partition_image.bin这文件后重启就自动产生2个nanda和nandb节点了，求指点！
