These are results I get for both of the nandbiterrs tests.

# nandbiterrs -i /dev/mtd1
incremental biterrors test
Successfully corrected 0 bit errors per subpage
Inserted biterror @ 0/5
Read reported 4 corrected bit errors
ECC failure, invalid data despite read success

# nandbiterrs -o /dev/mtd1
overwrite biterrors test
Read reported 4 corrected bit errors
Failed to recover 1 bitflips
Bit error histogram (883 operations total):
Page reads with   0 corrected bit errors: 845
Page reads with   1 corrected bit errors: 0
Page reads with   2 corrected bit errors: 0
Page reads with   3 corrected bit errors: 0

I guess this means ECC is there and it's working.

Thanks,

Daniel
