When I enable TI’s 28379D, I cannot activate external mode. I don’t know what the problem is.

Answers to the following questions will be helpful:

  • Are you able to flash the microcontroller? If so, does it behave as expected before trying to launch the external mode?
  • Are you experiencing the issue for all PLECS models or just some PLECS models? If the issue is only present for some PLECS models, would you be able to post one such model?
  • How are you connecting to the microcontroller? Serial? Are you using a LaunchPad or ControlCard interface? Something custom?
  • Are you able to connect if you increase the discretization step size in the Coder Options? If so, you could place a CPU load block in the model to gauge how close you are to the CPU utilization limit. It is possible that the model works fine but the external mode puts us over the top.
