This project uses a tool called kas to build the yocto image. It requires a Linux environment to have a consistent build. I've tried using Podman/Docker on MacOS, but ran into some issues with how the image interacts with the file system. I haven't tested with WSL or Podman/Docker on Windows yet.
To use kas without a container, setup your build environment as
described in the yocto quick build page
and install kas. kas install guide
To use kas with a container, install Docker/Podman then use the kas-container script
in the kas repo instead of kas.
Make a workdir
mkdir charin-demo
cd charin-demo
Clone the repo in the workdir
git clone https://github.com/catarial/meta-charin-demo
Run kas
<path to kas/kas-container> build meta-charin-demo/config.yml
You might need to create /usr/include/python3.11 if it doesn't exist
on your system or container. The build doesn't add anything to
that directory, it just fails if it doesn't see it.
I included files that have not been integrated into the build process yet in the state directory. This includes configs for everest and wpa_supplicant.
After you flash your image you need to copy over these files manually.
Connect over ethernet, (charger's ethernet address is set to 192.168.1.100).
Copy umwc-wifi.conf to /etc/wpa_supplicant.conf, wpa_supplicant.service
and everest.service to /usr/lib/systemd/system, and copy the everest
config you want to /etc/config-charin.yaml
