I'm using the NAND-Flash controller on the BF548M.
I wonder, whether it is possible, that it generates ECC
codes with all bits set to 1. Or does the algorithm guarantee,
that there area always 0-bits in the ECC codes?
If this was not possible, it would be quite easy to distinguish
an unprogrammed and therefore invalid ECC byte in the spare
area of the NAND-Flash from a valid code.
Thanks & kind regards,
