Original question:

MCF8329EVM: Motor Studio MPET operation fail and fault

MCF8329EVM: SmartTune Fail and PCB Rev Change

Robert Maier

Part Number: MCF8329EVM
Other Parts Discussed in Thread: MCF8329A

Tool/software:

First off. My PCB looks different than in the instructions. I can't find SW1, and some other minor differences. It says MD098A-001 on it. Not sure if this is the root cause of the next issue.

Assuming the missing components on my PCB can be omitted, I try to begin with SmartTune. The display is grey, inactive. I eventually get a CONTROLLER_FAULT and an MPET_BEMF_FAULT.

The bus voltage is about 24V. Here's the specs on the motor connected to the EVB:

Thanks!

    Hi Robert,

    >> could you please share the picture of your EVM board?

    >>SmartTune support for MCF8329A is under development, updated version will be released by end of this month.

    Please share your motor's number of poles, we can help you with the default JSON file which you can use as the base.

    Thanks,
