有哪位大牛用过ubifs么，我的怎么都不成功？

Question

成功编译了mtd-utils-266061e

在第二分区上格式化就有问题了：

挂载也有问题：

哪位弄过给指点一二？谢谢！

Answer 1

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。

Answer 2

UBI device number 7, total 1024 LEBs (130023424 bytes, 124.0 MiB), available 0 L
EBs (0 bytes), LEB size 126976 bytes (124.0 KiB)                                
UBI error: ubi_read_volume_table: the layout volume was not found               
ubiattach: error!: cannot attach "/dev/mtd1"                                    
           error 22 (Invalid argument)
这个我也遇到，什么原因？
