Hi Michael, I just cloned https://github.com/casper-astro/tutorials_devel.git and compiled tut3_noquant_r111 against mlib_devel b6e70b660910482b1f1028d32d29284468e38cda using Xilinx 14.7 and MATLAB 2012b (I ran update_casper_blocks(bdroot) on the model, and changed the target for roach2 before compiling).
The resulting boffile outputs reasonable looking spectra when snapped with tut3_noquant_r111.py from the tutorials_devel repository (with default options, specifying only the boffile and roach2 host). I printed the first 20 channels and there are no zeros.
