02. Initial Installation

Introduction

Burn the NEQTO Engine to Spresense using your local PC.

Please refer to the Spresense system configuration and combine the Spresense hardware components beforehand.

The following describes the procedure when using the Spresense hardware configuration above.

Before burning the NEQTO Engine to Spresense, please check the following notes:

IMPORTANT

  • Once the NEQTO Engine has been burned to Spresense, it will no longer be possible to rewrite it with application software you develop using the Spresense SDK. Please note that it is not possible to return to the initial state when Spresense was purchased.

  • When burning the NEQTO Engine to Spresense, be careful not to turn off the power until the burn is complete. It will be the cause of the failure.

  • The burning tool executes a dedicated application (.exe) on your local PC. Please note that if the operation of the application is restricted due to the influence of the security function or security software of your PC, it may not operate normally.

This initial installation procedure can be applied as a local firmware upgrade procedure for Spresense that already has the NEQTO Engine installed.
In that case, the parameters already set to Spresense are inherited and only the firmware is updated.
