DRV8711EVM: basic EVM bring up issues

Bill Krenik

Part Number: DRV8711EVM

I'm trying to get my DRV8711EVM working.  The D3 LED flashes, D2 never comes on.  When I hit the Nsleep button, it turns green (not sure if that means anything), but D3 continues to flash.  While I followed the instructions very carefully, I have no way to tell if I'm communicating with the device or not.  How do I know if I'm even getting register access to the MSP430?  Needless to say, I can't get the motor to turn.  Any help would be appreciated.  Thanks.

    Hi Bill,

    Have you confirmed you have the correct COM port selected? If you do and are communicating with the MSP430, the nSLEEP test point will toggle from low to high as the GUI pin toggles from red to green.

    Other test points that can be used to verify communication are RESET and DIR.
