BOOST-DRV8711A won't drive

I have a pair of BOOST-DRV8711A boards connected to MSP-430G2EXPs, as specified in the user guide. They're programmed and happy (CCS 6.2, GUI tool 6.0) and communicating. I'm only trying to use one at a time right now. I've got indications that the GUI is talking to the 8711, in the form of monitoring registers and apparently getting live feedback, but I have zero spin on my motors. Both motors under test are known good units, one likes 3.5Apk (2.8ARMS), one likes 2.5APk (1.75ARMS). Both should be well within the capabilities of the board, and both are well within the capabilities of my 24V 8A supply (which is staying nice and stable at 24.12VDC the whole time). Activating a start/stop profile or a step# profile produces a lack of output. No voltage switching is occurring on the outputs of the DRV8711, and no reluctance can be perceived on the motor shaft from applied power. 

Here's what the setup looks like:

I've tried every manner of reset I can think of with negative improvement. I just want my motor to spin!

Help?
