Q: I’ve received an error, such as (LoadProhibited). Exception was unhandled., what should I do?

A: In some cases, the NVM partition needs to be formatted. For this a format of whole Flash Memory should be performed.

This can be done using the cli version of the Firmware Update Tool, so please navigate where the app was installed (search for pycom-fwtool-cli executable) and execute:

pycom-fwtool-cli -p <PORT> erase_all

<PORT> should be replaced with the actual USB COM port, for example:

  • on Windows COM10
  • on Linux /dev/ttyACM0
  • on MacOS /dev/tty.usbmodemPy8eaa911
