This doesnt work on Ubuntu 20

[STashakkori]

I don't know if this is because of ubuntu 20 incompatibility or someone if the tool is simply broken but if you run the example line:
./bruteforce-crc --file test.txt -width 10 --offs-crc 49 --start 0 --end 49

You will get:
Warning: input reflection only works if range start ... end is N * 8 bit with N > )
No model found.

The README instructions actually contain a typo: ./buteforce-crc etc etc etc

I hope that doesn't mean this tool wasn't actually tested. Hope this helps

Thank you for your feedback. I updated the documentation. It was not in sync with how the tool should be started after several changes. Please try:

./bruteforce-crc --verbose 1 --file data.txt --start 0 --end 49 --width 10 --offs-crc 49 --probe-initial true

Warning: input reflection only works if range start ... end is N * 8 bit with N > 0
