Stefan Agner e83e6f4712 Add Amber as new machine (#1569)
* Add Amber machine

Introduce a new machine for Amber. Store it under Raspberry Pi boards
since Amber is based on the Raspberry Pi Compute Module 4. This way we
can reuse existing scripts.

* Add kernel patches for Amber

Add kernel patches which add a custom device tree for Amber.

* Add device wipe support via GPIO button

Allow to wipe the device by pressing and holding the red button.

* Enable serial console by default

Enable serial console on the on-board USB-to-UART adapter as well as on
the GPIO header.

* Use 64-bit mode by default

Support only 64-bit for Amber, it is mature enough.

Home Assistant Operating System

Home Assistant Operating System (formerly HassOS) is a Linux based operating system optimized to host Home Assistant and its Add-ons.

Home Assistant Operating System uses Docker as Container engine. It by default deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is not based on a regular Linux distribution like Ubuntu. It is built using Buildroot and it is optimized to run Home Assistant. It targets single board compute (SBC) devices like the Raspberry Pi or ODROID but also supports x86-64 systems with UEFI.

Features

  • Lightweight and memory-efficient
  • Minimized I/O
  • Over The Air (OTA) updates
  • Offline updates
  • Modular using Docker container engine

Supported hardware

  • Raspberry Pi
  • Hardkernel ODROID
  • Intel NUC
  • Asus Tinker Board
  • Virtual appliances

Development

If you don't have experience with embedded systems, Buildroot or the build process for Linux distributions it is recommended to read up on these topics first (e.g. Bootlin has excellent resources).

The Home Assistant Operating System documentation can be found on the Home Assistant Developer Docs website.
