SWUpdate handler is a reference implementation of an Update Content Handler that enables a device to support an Image-based Update (A/B)
Note | This handler is provided for demonstration purposes only.
This handler invokes tasks provided by the adu-shell command-line tool, which acts as a broker for executing specific tasks as root.
For some tasks, adu-shell will execute adu-swupdate.sh script, which implements the required business logic for:
- Update image signature validation
- Update image installation
- Boot loader configuration
- Device reboot
Note | This implementation may not be applicable with your device configuration (e.g., mismatch partitions layout). To support your device, some customization may be required.
