Hi Paul, Thanks for your email. It looks like your mlib_devel and casperfpga version are fairly recent and contain the BRAM 32 bit fixes that we made. It seems I committed this particular fpg file 9 months ago, so it might not of contained all these fixes then. I am quite certain it was working for me, but maybe I committed the incorrect file at the time. You say the first two tutorials were successful and I know the second tutorial has a snapshot, so your build environment must work. I am assuming you build the slx files and generated the fpg files for the first two tuts, of course. Correct me if wrong!
Please try and rebuild the spectrometer slx file and test the fpg generated file. Let me know if you get the same issue. If you don't then I must have checked a suspect fpg file in this repo and we can easily fix that, if that is the case.
