Hi.I am trying to drive large-page nand flash with the eLBS FCM of P1020.
But when i wrote full-entire page with ecc generation(FBCR[BC]=0),all data was sucessfully written other than ecc data which is from Flash ECC block n registers(eLBC_FECCn).And the lower 24bits value eLBC_FECCn always are zeroes after transfer finish.
After read entire-page data of flash with ecc checking,the transfer error ecc register captures no error informmation.And the lower 24bits value eLBC_FECCn always are also zeroes after transfer finish.
what's problem i may have?
