Part Number: BOOSTXL-DRV8320RS
Other Parts Discussed in Thread: LAUNCHXL-F280049C

Hi Team,

I'm writing this E2E thread for my customer, they using our BOOSTXL-DRV8320RS + LAUNCHXL-F280049C and successful to control a BLDC motor by Code Composer Studio.

Now since they plan to drive higher motor current, so they fully follow our BOOSTXL-DRV8320RS and LAUNCHXL-F280049C  schematic and layout to design their own board. But still using our LAUNCHXL-F280049C SPI to USB cable to connect to their NB running our Code Composer Studio.

When they testing their own DRV and DSP board to control a no load motor, some time(fail rate 20%) the CCS will show Error -1044 & -1156, when they assemble the motor to their system(have the system weight load) then the CCS will 100% show Error -1044 & -1156 once the motor start to moving, it's connectable at first, but show error after the motor start to run.

Could we have E2E expert help to investigate  this issue? 

Or do you have any idea or suggestion regarding Error -1044 & -1156?    

The Error message like as below:
