Description
Arduino is a popular microcontroller platform known for its low-cost hardware. Many people use Arduino to build a wide range of small projects. Some of these projects also require a firmware update feature. While Arduino supports self-flashing, that alone is not sufficient. If the latest firmware has issues, a buggy update could potentially break the system. In such cases, the only way to recover the system is to manually reflash a working firmware. To avoid such situations, a firmware rollback feature becomes essential. However, this requires additional hardware to store both the new and old firmware versions.
In this project, I am developing a custom bootloader that can back up the old firmware, flash the new firmware, and verify its functionality. If any issues are detected, the bootloader automatically rolls back to the backed-up firmware, ensuring the platform remains operational.
