I'm basing my implementation in the S3C SoC path publishied by Vincent Sanders in the QEMU-Devel list and the mini2440 Source Code, combined with the user manual of Samsung S3C2440A. Now i'm trying to implement the NAND Flash controller. I have see that mini2440 don write some registers such as: NFSTAT. Now i'm implementing the ECC, but don't understand wath is the 1st ECC, 2nd ECC, 3rd ECC and 4th ECC. The mini2440 only have implemented the 1stECC and 2nd ECC. If you can explain me about it or recommend me some reference. Best regards -- ************************************************ Lic.
