UBI文件系统问题-AM335x

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：

请参考如下链接：

http://www.linux-mtd.infradead.org/faq/ubi.html#L_subpage_verify_fail

I get "ubi_io_write: error -5 while writing 512 bytes to PEB 5:512"

If you have a 2048 bytes per NAND page device, and haveCONFIG_MTD_NAND_VERIFY_WRITE enabled in your kernel, you will need to turn it off. The code does not currently (as of 2.6.26) perform verification of sub-page writes correctly. As UBI is one of the few users of sub-page writes, not much else seems to be affected by this bug.

建议找到uboot和内核中的CONFIG_MTD_NAND_VERIFY_WRITE 宏定义尝试注释后，看能否解决。

都已经去注释掉了，还是不行

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 0
ubiattach /dev/ubi_ctrl -m 7 -O 2048
ubimkvol /dev/ubi0 -N rootfs -s 500MiB
mount -t ubifs ubi0_0 /mnt
cd /mnt
tar zxvf ../base-rootfs-am335x-evm.tar.gz
cd ..
umount /mnt
halt

在解压过程中也会报错：

有时候还有这种错误：
