linux 如何使用 BCH8

5529

问答对人有帮助，内容完整，我也想知道答案 0 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。 0

答案对人有帮助，有参考价值 0 请问您用的是什么型号的NAND FLASH。在我们demo板上，有SDK06的版本，不用做任何ECC配置，就可以成功挂载ubifs的。

答案对人有帮助，有参考价值 0 rfffwef 发表于 2018-5-15 03:48 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：我用中文总结了一篇ubifs文件系统的guide，请参考： http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/59921.aspx
