zero3w-gs

Files and installation script for the Radxa Zero 3w to run as an openipc groundstation.

Instructions

Setup env on Ubuntu 20.04 for rsdk by running these commands:

sudo apt update
sudo apt install git npm qemu-user-static binfmt-support curl docker.io -y
sudo usermod -a -G docker $USER
# Reboot for the above command to take affect
sudo reboot

Setup rsdk:

git clone --recurse-submodules https://github.com/RadxaOS-SDK/rsdk.git
cd rsdk
npm install @devcontainers/cli
export PATH="$PWD/src/bin:$PWD/node_modules/.bin:$PATH"

Create an overlays directory
```
mkdir overlays
cd overlays
```

Clone Radxa Image build script

git clone https://github.com/JohnDGodwin/zero3w-gs.git
#Move back to the rsdk root folder
cd ..

Modify the file src/share/rsdk/build/rootfs.jsonnet to run script during image build. Include the following lines inside the customize-hooks section
```
'cp -r "overlays/zero3w-gs" "$1/"',
'chroot "$1" chmod +x /zero3w-gs/install-gs.sh',
'chroot "$1" sh -c "cd /zero3w-gs && ./install-gs.sh"',
```

customize-hooks section should now look like this:

"customize-hooks"+:
    [
        'echo "127.0.1.1	%(product)s" >> "$1/etc/hosts"' % { product: product },
        'cp "%(output_dir)s/config.yaml" "$1/etc/rsdk/"' % { output_dir: output_dir },
        'echo "FINGERPRINT_VERSION=\'2\'" > "$1/etc/radxa_image_fingerprint"',
        'echo "RSDK_BUILD_DATE=\'$(date -R)\'" >> "$1/etc/radxa_image_fingerprint"',
        'echo "RSDK_REVISION=\'%(rsdk_rev)s\'" >> "$1/etc/radxa_image_fingerprint"' % { rsdk_rev: rsdk_rev },
        'echo "RSDK_CONFIG=\'/etc/rsdk/config.yaml\'" >> "$1/etc/radxa_image_fingerprint"',
        'chroot "$1" update-initramfs -cvk all',
        'chroot "$1" u-boot-update',
        'cp -r "overlays/zero3w-gs" "$1/"',
        'chroot "$1" chmod +x /zero3w-gs/install-gs.sh',
        'chroot "$1" sh -c "cd /zero3w-gs && ./install-gs.sh"',
        |||
            mkdir -p "%(output_dir)s/seed"
            cp "$1/etc/radxa_image_fingerprint" "%(output_dir)s/seed"
            cp "$1/etc/rsdk/"* "%(output_dir)s/seed"
            tar Jvcf "%(output_dir)s/seed.tar.xz" -C "%(output_dir)s/seed" .
            rm -rf "%(output_dir)s/seed"
        ||| % { output_dir: output_dir },
    ]

Now you can follow the steps to start the devcontainer and build the image
```
rsdk devcon up
rsdk devcon
rsdk shell
rsdk build radxa-zero3 bullseye cli
```

The script will do the following:

update, upgrade, and install some packages with apt
setup the /config directory where the user settings and scripts are stored
setup openipc systemd streaming service
install a media server for dvr
install wi-fi drivers
install wfb-ng
install PixelPilot
configure hotplugging of wfb-nics
