I config imx28 GPMI NAND with following parameters:
1. gpmi clock = 120MHz
2. NandTiming.DataSetup = 40ns
3. NandTiming.DataHold = 30ns
4. NandTiming.AddressSetup = 30ns
5. RDN_DELAY = 0, DLL_ENABLE = 0
The above settings works fine with K9F1G08U0C, but get ECC error with K9F1G08U0D quite often. It's appreciated for any comments.
