Unable to initilize bch, invalid parameters?

[JavierBaratech]

I have the following ouput when I executed the nand-decoder script:

./nand_dump_decoder.sh -i /chipoff/ -o test.bin -m ATMEL --atmel-config

[] Found one binary input file (138412032 bytes)

bch = bchlib.BCH(config['ecc_polynom'], config['ecc_errors'], False)
RuntimeError: unable to inititalize bch, invalid parameters?

Do you have any suggestion? Thanks in advance.

Been slamming my head into this for the better part of a day. It appears that when bchlib moved to version 1.0.0, it changed everything about the lib.

Run 'pip uninstall bchlib' and then 'pip install bchlib==0.7'

This change worked for me.
