ELK Audio OS builder

This repository contains the dockerfile needed to build the ELK Audio OS builder docker image.

This Docker image contains the Elk Audio SDK for Raspberry Pi and the JUCE framework to cross-compile VST3 plugins for Elk Audio OS.

It also has a configuration for the KAS tool to automate the bitbake configuration and build process for an entire Elk Audio OS image.

Setup

Configure and install the docker image on your system

docker image build -t elk-audio-os-builder .

(if you're running Docker Desktop on a Silicon Mx Mac, add the option --platform linux/amd64 after build).

Run the container

sudo docker run --name elk-audio-os -dit --rm elk-audio-os-builder
sudo docker attach elk-audio-os

You only need sudo with Docker engine on Linux, but not on Docker Desktop for Mac/Windows.

If you're on Apple Silicon, you need again to pass the option --platform linux/amd64 to the docker run command.

Compile the JUCE AudioPlugin example

Inside the home directory of the container, there is a modified version of JUCE's CMake example for AudioPlugins pre-configured for this system.

You can test it with

cd ~/examples/AudioPlugin
mkdir -p build && cd build
source /SDKs/elkpi/environment-setup-cortexa72-elk-linux
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j`nproc`

Build a full Yocto image for Elk Audio OS

Build the image (Raspberrypi4 with ELK Audio OS 1.0.0 shown)

git clone https://github.com/elk-audio/elk-audio-kas-configs
cd elk-audio-kas-configs
run-kas build raspberrypi4/raspberrypi4-elk-audio-os-v1.0.0.yml

If you need to build the SDK run

run-kas build raspberrypi4/raspberrypi4-elk-audio-os-v1.0.0.yml -c populate_sdk
