我想挂载ubi0_1卷（boot-resource）修改里面的开机logo

# mount -t ubifs ubi0_1 /mnt/boot
mount: mounting ubi0_1 on /mnt/boot failed: Invalid argument

挂载失败！

ubi0_5 (rootfs)可以挂载，ubi0_7 （UDisk）也可以挂载。
其他卷都无法挂载。

ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据，但是如何修改boot-resource.fex里bootlogo.bmp，或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件，然后再用上面命令来更新卷数据

@y97788 在 ubifs卷挂载问题中说：

你好，我也碰到了这个问题，请问你解决了吗
