This README file contains information on the contents of the meta-seeed-cm4 layer.

Supported Devices

This meta layer supports the following Seeed Studio devices:

• seeed-reterminal: reTerminal (Raspberry Pi CM4)
• seeed-reterminal-DM: reTerminal DM (Raspberry Pi CM4)
• seeed-recomputer-r100x: reComputer R100x (Raspberry Pi CM4)
• seeed-recomputer-r110x: reComputer R110x (Raspberry Pi CM4)
• seeed-rerouter-cm4: reRouter CM4 (Raspberry Pi CM4)
• seeed-recomputer-r2x: reComputer R2x (Raspberry Pi 5)
• seeed-recomputer-r22: reComputer R22 (Raspberry Pi 5)

Each device has both standard and Mender-enabled variants for OTA updates.

For more detail of project compiling

Please see the GitHub Actions workflow file:

• .github/workflows/seeed-boards.yml: Automated builds for all supported devices with Mender integration

Building Images

You can build images for supported devices using the KAS configuration files in the kas/ directory:

• seeed-recomputer-r100x-mender.yml: reComputer R100x with Mender
• seeed-recomputer-r110x-mender.yml: reComputer R110x with Mender
• seeed-reterminal-mender.yml: reTerminal with Mender
• seeed-reterminal-DM-mender.yml: reTerminal DM with Mender
• seeed-rerouter-cm4-mender.yml: reRouter CM4 with Mender
• seeed-recomputer-r2x-mender.yml: reComputer R2x with Mender
• seeed-recomputer-r22-mender.yml: reComputer R22 with Mender

After several hours of compiling, you can get the image in build/tmp/deploy/images/<machine-name>/ with .wic.bz2 suffix.
