  • Hi Wenhao Xu,

    NAND flash always has some factory marked bad blocks so seeing some blocks identified as bad even on new boards should not be considered an error.

    Even during normal erase/write cycles, some bad blocks may develop. However, if you see behaviour where bad blocks are developing very rapidly and corelate to all the blocks U-Boot/Kernel writes to then there could be some software issue.

    Do you see such a behavior?

    Thanks,

    Sekhar

  • Hi,

    Can you report if you are seeing different set of bad erase blocks on different boot up times? For example from your log above, you have bad erase block 2, 6, 9, 11, 14 etc... 

    Do you see the same set of bad erase blocks 2,6, 9, 11, 14..... every time you boot up.

  • hi,Sekhar,

    I found the bad blocks is not develop so quickly,but every times power on the bad blocks is random,is the bad block is physical of software errors?the following is the information.
