Gecko Bootloader#

The Gecko Bootloader is a program stored in reserved flash memory that can initialize a device, update firmware images, and may also perform integrity checks. Devices are typically programmed with firmware during the product manufacturing process. A bootloader allows for reprogramming devices after production is complete, to add features or fix bugs.

The content on these pages is intended for those who want to experiment with or are already developing a bootloader for use in your devices.
