    2. Get to Know the Software

    Build the required software

    The primary EasyEVSE application software for the EVSE and EV runs in the Linux operating environment on the i.MX 93 host controllers. (The same flash image is used on both i.MX 93 host controllers) A Linux PC is required to build the i.MX Linux image.

    The below sections provide links to the required software.

    2.1 Build the Linux Image with Yocto

    Follow the instructions at github to build the i.MX 93 EasyEVSE software image on your Linux build host. Consult the i.MX Linux User's Guide for details. 

    LOG_LEVEL=ALL
1. $ repo init -u https://github.com/nxp-imx-support/nxp-easyevse-mpu-manifest -b release/easyevse-mpu-2.0 -m imx-6.1.55-2.2.0_evse.xml
2. repo sync
3. $ DISTRO=fsl-imx-wayland MACHINE=imx93evk-easyevse . imx-setup-easyevse.sh -b build_imx93 -r humble 
4. bitbake imx-image-easyevse

    Consult the i.MX Linux User's Guide for details flashing the system image on the i.MX 93 EVKs. The same image runs on both the EVSE and EV. 

    LOG_LEVEL=ALL
5. cd tmp/deploy/images/imx93evk-easyevse
6. uuu -b emmc_all imx-boot imx-image-easyevse-imx93evk-easyevse.wic.zst

    2.2 EVSE-SIG-BRD Firmware

    The firmware for the LPC5536 needs to be pre-loaded on the EVSE-SIG-BRD1X signal board. Consult the EVSE-SIG-BRD1X User Guide for instructions on recompiling and installing the firmware as necessary. Please follow the instructions for the MCUXpresso installer for Linux to flash the EVSE-SIG-BRD1X with the related binary file here.

    3.1 Cloud Application

    Please watch the beginning of the Ethernet Solution video in the section 3.1

    This video describes the creation and setup of Azure IoT Central application, using a shareable link template and the configuration of a mutually secure and authenticated connection with the Azure Iot Central. Also the User Guide of the EasyEVSE Development Platform (Linux OS, Wi-Fi 6) provides additional information on how to use the Azure IoT Central application to monitor telemetry, update properties and send commands to your EasyEVSE device.

    The account creation and template setup of Azure IoT Central is applicable for the Ethernet and Wi-Fi solution.
