成功编译了mtd-utils-266061e

Flash芯片:K9F1G08U0B          128MiB

分区信息:
[root@localhost /usr/mtd]# ./mtdinfo  -a

[root@localhost /usr/mtd]#

在第二分区上格式化就有问题了:

挂载也有问题:

ubiattach: error!: cannot attach "/dev/mtd1"
           error 22 (Invalid argument)
[root@localhost /usr/mtd]#

哪位弄过给指点一二?谢谢!

Flash芯片是新的,用uboot格式化的时候没有坏块的,前面烧写的uboot和 uImage都是好用的

用ubiformat后就越用坏块越多,好像被他误标了。
