BOOSTXTL-DRV8323RH

Other Parts Discussed in Thread: BOOSTXL-DRV8323RH, MSP-EXP430F5529LP

Hi Experts, 

I have these two EVM Kits, BOOSTXL-DRV8323RH, and MSP-EXP430F5529LP LaunchPad.

When I connect to my motor and set up all the test environments by using the DRV8323RH GUI. It's easy to use. 

But when I use the sensorless FW, I always triggered the "Stall Fault" when the speed is lower or equal to 20%. 

If I used the sensored FW, it always triggered "Stall Fault" during start-up, and cannot spin. 

Does there any document about the motor "Stall" that could be referenced? How can I fix it ?

Thanks
