问题描述
我已经使用ubi文件系统和mtd子系统在NAND闪存的顶部工作.一切正常.
I have used ubi filesystem and mtd subsystem to work on the top of NAND flash.It was working fine.
但是现在我发现以下错误:
But now I'm finding the following errors:
UBI错误:ubi_io_read:错误-74，同时从PEB 2701:8192读取516096字节，读取516096字节
UBI error: ubi_io_read: error -74 while reading 516096 bytes from PEB 2701:8192, read 516096 bytes
end_request:I/O错误，dev mtdblock5，扇区49160
end_request: I/O error, dev mtdblock5, sector 49160
我上面提到的那些错误的原因是什么?如何从这些错误中恢复?
what is the reason for those errors which I have mentioned above?How to recover from these error?
推荐答案
两者均显示与NAND闪存上的损坏或坏块有关的I/O错误，请尝试使用其他闪存.您还可以尝试擦除Flash，然后重试.
Both shows I/O errors which is related to corruption or bad block on your NAND Flash, try using another flash and use it. You can also try erasing flash and trying it again.
