dm8168 Linux搭建 UBI文件第二次断电启动后报错

Other Parts Discussed in Thread: PCF8575

编译uImage的内核是DVRRDK4.0版本，目前遇到的问题时第一次启动都正常，UBI文件系统不会报错，但是第二次就会一直刷

UBI: run torture test for PEB 1993
UBI: PEB 1993 passed torture test, do not mark it as bad
UBI error: ubi_io_read: error -74 (ECC error) while reading 512 bytes from PEB 0:512, read 512 bytes
UBI error: ubi_io_read: error -74 (ECC error) while reading 512 bytes from PEB 1993:512, read 512 bytes

第三次启动就会刷几次上面的打印后内核崩溃

下面是第三次启动的log：
