Nand Flash ECC Failed

This question is a continuation of MQX MFS Nandflash ECC Failed

After getting a working solution and testing it several times, I now have the same error again.

The solution I found is not working anymore, and I can only guess at what sequence of events led to a working solution before.

 

Symptoms:

- Using MFS nandflash example (with ffs wearlevelling), I get ECC_FAILURE / NFC_ECC_STATUS_CORFAIL

- Using Mqx nand driver I get the same error inside nfc.c

- Setting BSP_ECC_SIZE to 0 gives a working system using Mqx nand driver.

 

Since my tests pass using BSP_ECC_SIZE=0, I assume this is a problem with the configuration or with the ECC engine in the cpu ( Vybrid MVF61NN151CMK50 )

 

My setup is as decribed in previous thread.
