My attempt at putting magicmirror on the IOT Edge and learn on a rock-3a

1. portal.azure.com
   • Create IOT Hub (rpi4iothub)
   • Create Iot Edge Device (rk3adevice)

Start Raspberry Pi Imager download https://github.com/radxa-build/rock-3a/releases/download/main-a7204124/rock-3a-ubuntu-focal-server-arm64-20220501-0200-gpt.img.xz select and write rock-3a-ubuntu-focal-server-arm64-20220501-0200-gpt.img.xz

install sd in rock-3a ssh [email protected]

$ sudo apt-get update

$ sudo apt-get install -y rockchip-overlay

$ sudo apt-get install -y linux-4.19-rock-3-latest

config using the /boot/uEnv.txt

1. NO Wifi? : only if you buy the adapter!!!

Install IOT Edge https://docs.microsoft.com/en-us/azure/iot-edge/how-to-provision-single-device-linux-symmetric?view=iotedge-2020-11&tabs=visual-studio-code%2Crpios for Ubuntu 20.04

sudo apt install wget wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb sudo dpkg -i packages-microsoft-prod.deb rm packages-microsoft-prod.deb sudo apt-get update;
sudo apt-get install moby-engine

sudo nano /etc/docker/daemon.json

• { "log-driver": "local", "dns": ["ip.of.my.localRouter"] }
  • sudo systemctl restart docker

sudo nano /etc/sysctl.conf - uncomment line below net.ipv4.ip_forward=1 sudo systemctl restart docker

sudo apt-get update;
sudo apt-get install aziot-edge defender-iot-micro-agent-edge

sudo iotedge config mp --connection-string 'PASTE_DEVICE_CONNECTION_STRING_HERE' sudo iotedge config apply sudo iotedge check

When you create a new IoT Edge device, it will display the status code 417 -- The device's deployment configuration is not set in the Azure portal. This status is normal, and means that the device is ready to receive a module deployment.

1. Time to set up vscode
   • https://devblogs.microsoft.com/iotdev/easily-build-and-debug-iot-edge-modules-on-your-remote-device-with-azure-iot-edge-for-vs-code-1-9-0/

sudo usermod -aG docker $USER newgrp docker -test setting like this docker run hello-world

- https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys-on-ubuntu-20-04

on dev/vscode computer run: ssh-copy-id username@remote_host 2. in vs code workspace settings from command line pallet add these lines only ip of rpi works for some reason do not try name "azure-iot-edge.executor.env": { "DOCKER_HOST": "ssh://username@remote_host" },

Azure portal Set modules on device -> Runtime Settings for agent hub image need to be updated from 1.1 default to 1.2 for some reason, USE: Image uri: mcr.microsoft.com/azureiotedge-agent:1.2 and Image Uri: mcr.microsoft.com/azureiotedge-hub:1.2 for agent and hub perspectively.

VScode DEV environment builds fail with: Get "http://localhost:5000/v2/": dial tcp 127.0.0.1:5000: connect: connection refused fix in project solution with: devcontainer.json uncomment: "forwardPorts": [5000, 5001],

• and removed redistry2 container from docker to get it to rebuild and push on the next build and push IoT Solution
