Use it to store persistent data that doesn't change between updates.

Must be exactly the same size as /dev/mmcblk0p2.

Second root filesystem: /dev/mmcblk0p3.

Mounted as root on a fresh install of Raspberry Pi OS.

First root filesystem: /dev/mmcblk0p2.

Make sure the partitioning structure on the Raspberry Pi is as follows: due to a power supply cut), the boot configuration remains unchanged, preventing bricking of the device. If, for any reason, the update fails (e.g. Therefore, both the partitions switch places as 'active' and 'inactive' after each update. The update image is installed on the inactive partition, and once the update is complete, the boot configuration is modified to use the updated partition as the root partition on the next boot. The dual-copy update strategy involves two root partitions where one is active while the other remains inactive. The update is applied through a update file, which is a system image of the root partition that will replace the current root. These scripts are capable of automatically updating the root filesystem of a Raspberry Pi. Please use these scripts for educational purposes only. As such, please do not use these scripts in a production environment. WARNING: The scripts do not currently support signed updates.

A collection of scripts that enable reliable OTA updates for Raspberry Pi based on 'Dual Copy' strategy.
