ubifs文件系统挂载失败

[andy1658]

最近由于工作需求，想做一个ubifs文件系统，但是挂载失败，请大侠帮忙分析一下，错误信息如下：

我制作ubifs文件系统步骤如下：
1、在kernel中添加ubifs文件系统相关的选项
2、制作ubifs.img文件并烧写经nand flash，但是就是挂载不上，请大虾帮忙分析，谢谢

怎么没人回帖呢？

1. 制作ubi image的命令行，reference: https://github.com/voiceshen/scripts4linux/tree/master/ubifs 2. 启动系统的命令行参数。

我就是按照这个方式制作的ubi image，但是我不知道ubi0_0这个文件是怎么创建的，启动的时候会导致失败，请高手指点，谢谢

求高人指点啊

问题已经解决了，是我在uboot下烧写rootfs的时候，没有跳过坏块导致，谢谢各位的回答

[JaggerJiao]

1.在uboot里，setenv nand_root ubi0:rootfs rw ubi.mtd=2,2048 2.制作imgae时，mkfs.ubifs -c 这个参数要仔细计算，些参数影响较大，再就是改一下ubinize.cfg这个文件的相关参数 3.再说一个我遇到的，开发用了gpio结果一个复用io被改了，结果造成nand read only，这个是驱动造成的，改一下内核驱动就可以了。 我就遇到这些，希望能帮到你。
