DRV10987EVM: Software interface font exception

Hi team,

1) DRV10987EVM Software Interface Font Display is incomplete, what could be the possible cause? Windows 11 and Windows 7, 64-bit systems are used. 

2) Software interface to set up the analogue speed to control motor, the motor will turn for a few seconds and then stop, and turn and stop again (repeated stalling). Also, the speed is low and the analogue resistor speed is unchanged. Is it a software issue? 

Could you help check this case? Thanks.

Best Regards,

Cherry
