BDM problem

[macxlulu]

hello I have a small problem, I have a BDM dimsport 555 pro, everything is good but does not count CKS, and I have a problem with mpc555 in sid803 what to count checksum, I also cmd1255 clone, but it does not make sense to use a clone when I have the original preparation 555pro, I have someone some idea?
