Document Overview

The Gecko Bootloader is a versatile tool for Silicon Labs' newer MCUs and wireless MCUs, supporting device initialization and firmware upgrades using the proprietary GBL (Gecko Bootloader) format. It can operate in standalone mode, receiving firmware images via serial interfaces like UART or SPI, or in application mode, where the application code manages the firmware acquisition and update process.

This document details procedures for serial uploads (UART and SPI), error handling, and bootloader upgrades across different EFR32 device series, providing essential information for developers working with EmberZNet.
