02. Initial Installation

Introduction

Install the NEQTO Engine to STM32 Discovery Kit using your local PC.
Before beginning installation, please confirm the following matter:

IMPORTANT

  • Please be aware of the following precautions when installing the NEQTO Engine to STM32 Discovery Kit:

    • Be sure to connect only one STM32 Discovery Kit to the PC.
    • Do not access the COM port to which the STM32 Discovery Kit is connected.
    • Do not run the STM32 Programmer software
    • Be careful not to turn off the power until the installation is complete. It will be the cause of the failure.
