Other Parts Discussed in Thread: AM3354

Hi ,

We are using AM3354 processor with android jelly bean (4.1.2) and kernel version is 3.2. We are using 16 bit nand (MT29F4G16ABADAH4)..Suddenly we are facing ecc error issue in ubifs . U-boot and kernel ECC layout and all the things are same.

    Hi Biser,,

    Thanks but I think Its generic question .It's not particular for android . I m facing issue in NAND ECC error in Ubifs read. Any idea ? Or list of reason for this error. I already set relax NAND timing .
