Unable to initilize bch, invalid parameters? #5

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) [] Using ECC mode ATMEL [*] Used configuration Block size: 131072 bytes (64 pages) Page size: 2048 bytes Sector size: 512 bytes Spare size: 64 bytes ECC offset: 36 bytes ECC errors: 4 errors per sector (max.) ECC bytes: 7 bytes per sector Use ECC: True File offset: 0x0 (skip 0 blocks) Traceback (most recent call last): File "nand-dump-tools/nand_dump_decoder.py", line 1425, in ecc_method(input_files, args.outfile, config) File /nand-dump-tools/nand_dump_decoder.py", line 158, in atmel_error_correction 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.
