BDPsummary should have been generated in the same folder as the bfc file but since in your case it did not generate then most likely BDP exited before that step.
I repeated your command with a dataset I had :
bdp.exe 2523412\2523412.bfc.nii.gz –tensor –fract –frt –nii 2523412\2523412.DTI64.nii -b 2523412\2523412.DTI64.bval -g 2523412\2523412.DTI64.bvec
and it was able to find my file and went beyond the step that is crashing for you. So looks to be a syntax issue.
Even though I am not sure, here are quick pointers that might help you:
– check if all files exist and are accessible to bdp
– check space, double dashes
– remove fract and frt, just run tensor
– try a different input dataset
