Bootloader

In this article, we will explore how to safely perform OTA updates for the bootloader using the recovery bootloader feature.

This guide provides a practical getting‑started walkthrough for using MCUboot on ESP32. It covers step-by-step environment setup, bootloader building, application configuration, and flashing. It also gives an overview of MCUboot’s execution flow.

In this article, we explore a simplified ESP32 boot process using single-image binaries to speed up build and flash times — ideal for development workflows. This approach sacrifices features like OTA updates but enables faster iteration.
