linux 如何使用 BCH8

xidong Liang 说：

 335x的板子。内核板本是：linux-3.2.0-psp04.06.00.11

 制作的文件系统是ubifs的。使用的bootloader是使用硬件ECC,BCH8的。

 因为，烧写文件系统后，无法挂载。

初步分析原因是bootloader与linux 内核使用的ECC不一样。

如何要让内核支持ECC,BCH8的，在配置和源码里，主要修改哪里呢。

您所用这个版本的kernel默认已经是BCH8 了，请查查其他原因。

你好。

可能是制作ubifs文件系统的时候，没有制作正确。

具体打印信息如下：

这是没有把文件烧写到nand flash里的信息:

文件系统使用的是3715的文件系统。只是重新打包给335x。

文件系统在3715是可以正常使用的。

是使用create-ubifs.sh脚本命令来执行的。

 

 

我用中文总结了一篇ubifs文件系统的guide，请参考：
