TI大神们：
我正在使用AM3354+8G NANDFLASH(Page：2048+128)进行开发，u-boot版本：2011-09，kernel版本：3.2.0；目前遇到一个关于文件系统启动的问题。
在使用SD卡烧写文件系统时使用mmc rescan;fatload mmc 0 0x82000000 rootfs.yaffs2;nand erase 0x780000 0xF880000;nandecc sw; nand write.yaffs 0x82000000 0x780000 ${filesize}指令，即使用软件ecc汉明码校验时，从nandflash启动没有问题。
但由于客户需求全部使用硬件ecc校验方式，当我使用mmc rescan;fatload mmc 0 0x82000000 rootfs.yaffs2;nand erase 0x780000 0xF880000; nand write.yaffs 0x82000000 0x780000 ${filesize}，即没有ecc校验时，板子从nandflash启动会出现如下错误：
