I'm not sure what's wrong, but since it sounds like absolutely nothing is happening, I suggest verifying some of the basics: Make sure you can twiddle I/O pins via config-pin and halcmd:
Since you're using a 4.x kernel, I don't think the overlay lines in your bebopr_cape.bbio file will do anything. Make sure you have the universal cape loaded via u-boot overlays and test twiddling an I/O pin using the config-pin command. If that works, try loading just the HAL part of your configuration manually (I think you can just run the arcus_3d_c1.py and bebopr.py files). If that doesn't work, you can just make a simple test HAL file to load the hal_bb_gpio driver and create a servo thread. Make sure you start the threads (halcmd start) and see if twiddling the I/O pins (ie: bb_gpio.p8.out-07 & friends) via halcmd set has any affect. If either of those fail, the PRU is probably not working for the same reason...get the above fixed and things ought to work better.
