Overview

Getting Started

This guide depends on the following requirements:

• Peridio Cloud Configuration
• Peridio CLI Development Machine

Configuration

Generate Device Identity

Export the environment variables PERIDIO_CERTIFICATE_FILE and PERIDIO_PRIVATE_KEY_FILE to the location of the PEM files generated when configuring your signing PKI. For more information about device signing PKI, see creating CA certificates.

export PERIDIO_CERTIFICATE_FILE=/path/to/end-entity-certificate.pem
export PERIDIO_PRIVATE_KEY_FILE=/path/to/end-entity-private-key.pem

Create working directory

Create a working directory for building the khadas-vim3 machine.

mkdir build-avocado-khadas-vim3 && cd build-avocado-khadas-vim3

Checkout the meta-avocado project to your build directory

git clone git@github.com:peridio/meta-avocado

Build the System

You can build the project using kas. The product will have the device identity included as part of the runtime environment. Building this system may take a long time to complete depending on your build machine resources.

kas build --update meta-avocado/meta-avocado-example/conf/kas/machine/khadas-vim3.yml

Testing

Insert a microSD card and execute the following command to write the image:

fwup build/tmp/deploy/images/khadas-vim3/avocado-image-base-khadas-vim3.fw

Connect a serial console cable to the UART pins on the Khadas header

Serial tools pin	GPIO board header pin	Name
GND	17
TXD	18	Linux_Rx
RXD	19	Linux_Tx
VCC	20

Insert the microSD card and power on the board.
