Getting errors using FRDM-MC-LVBLDC shield

I recently bought an NXP development kit for BLDC motor control. The kit includes the following NXP parts

  1. FRDM-KV31F MCU development board
  2. FRDM-MC-LVBLDC motor interface shield
  3. FRDM-MC-LVMTR motor


My objective is to test and evaluate  NXP’s BLDC motor controller solution with the end goal of integrating it into a custom product for my Terra customer if it proves successful.


To help me become familiar with the NXP BLDC solution, I am using  NXP “Kinetis Motor Suite v1.2.0  Lab Guide” (document # KMSLG) and followed the directions for setting up the software environment and hardware configuration.


I tried running Lab #1 in the user guide and the motor will simply not run as fault conditions exist. The  error messages I got from the KMS GUI included incorrect  DC bus levels and the CPU resetting – see attached files.


Being knew to NXP’s motor control products,  It is hard for me to tell whether I have defective hardware or I have incorrectly set up the software/hardware. I really need to talk to someone familiar with this product so we can determine what the issue is.
