DRV8301: Hardware not indentified, DRV8301 and F28069M

Part Number:DRV8301

Hello,

I have a setup with a F28069M Launchpad, two BOOSTXL - DRV8301 and two motors. To begin, I would like to spin a motor to know if my setup is working. I am using instaSPIN for this but when I run the application the hardware is not identified. See the image below. I plugged 

So, my questions are : How can I verfiy that the Motor Drive is not dead ? Is there something I didn't do (like Switch S1 on the lauchpad) ? 

Best regards,

Maxime
