TI中文支持网我用的是AM3359处理器，把一个opt压缩文件拷到文件系统里面，解压缩之后出现这个问题：

请认真对比下 http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/p/11199/48044.aspx#48044里面的实验步骤。

我做的ubi.img怎么弄都不行，就不去弄了，改成内核烧写，步骤如下：
flash_erase /dev/mtd7 0 0ubiattach /dev/ubi_ctrl -m 7 -O 2048ubimkvol /dev/ubi0 -N rootfs -s 500MiBmount -t ubifs ubi0_0 /mntcd /mnttar zxvf ../base-rootfs-am335x-evm.tar.gzcd ..umount /mnthalt
在解压过程中也会报错：

你的问题解决了没？我遇到和你一样的问题了。我的处理器是OMAP-L138，内核为Linux-3.3。
使用的是SPI NOR Flash，（w25q128），内核分区为/dev/mtd2，ubifs文件系统分区为/dev/mtd3。内核加载文件系统出息如下错误，怎么解决？
你怎么解决的？
