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.
It is also possible to change from Spresense Wi-Fi firmware to Spresense LTE-M firmware, and from Spresense LTE-M firmware to Spresense Wi-Fi firmware.
In that case, the parameters already set to Spresense are inherited and only the firmware is updated.

From Version 02.00.00, the LTE module firmware version (RK_02_01_02_10_108_54) is required. The LTE module firmware is automatically updated as needed by the burning tool for Spresense LTE-M or by FOTA execution. The LTE module firmware update requires at least 20 minutes when using the burning tool, and at least 30 minutes when using FOTA. (It is recommended to update using the burning tool)
