DRV8305-Q1EVM: D1 Red LED, nFAULT on BOOSTXL-DRV8305EVM Always on

Dear Sir or Madam,

I plugged BOOSTXL-DRV8305EVM on LaunchPad™, LAUNCHXL-F28069M. Even though I didn't connect any wire to 28069 Launchpad and DRV8305, and just add the 12 VDC power to PVDD on DRV8305, the D1 red LED, nFAULT is on. Does the nFAULT on DRV8305 default is set up to on(0)? if yes, how can I set it up to off (1)? 

Thank you,

Hao
