Brian,

I was able to reproduce the bug as well. I tried this in a branch that was branched off of develop from a few weeks ago.

And yes, if the configuration id are not in numerical order it segfaults when building(I believe there is a ticket for it segfaulting).

Looks like this problem might reside in: opencpi/tools/ocpigen/src/hdl-worker.cxx

Brian,

I have you tried doing a make clean and then a rebuild?

Yes, I believe so. It's very reproducible for me. Like I said, if I put the 16-bit value first followed by 12-bit values, it builds the 16-bit ID fine, then fails for the 12-bit values. If I put a 12-bit value first, it will build that just fine, but fail on the 16-bit value.

Also interestingly, if I put something with a build id of 2 before a build id of 0, I get a crazy error.

Have you tried modifying your data_src with the extra build configuration and been successful in building?

If so, what version of OpenCPI are you using?

Thanks,
Brian
