TMS320F28027F: UART stop responding when motors are running

Other Parts Discussed in Thread: BOOSTXL-DRV8305EVM, DRV8305

Hi,

We are working on a project that use C2000 piccolo LaunchPad and Boostxl-DRV8305EVM booards.  We want to send command through UART (send configuration data, start motor to certain speed, stop motor, etc). Everything seems working fine until the motor start running to a certain speed (given through the UART)  but then UART stop responding and I cannot send command to stop the motor. Is there any reason why UART stop working while motor running and what do I need to do to present stalling?

Thanks a lot!
