IronOS DFU Bootloader for Miniware

This is a replacement bootloader for Miniware irons. This replaces the build in bootloader with one that can be used with dfu-util.

How it works

This bootloader builds in two versions for each supported hardware. A bootloader and a runtime version.

Bootloader

The bootloader version is intended to be used as your device bootloader. It will only go into USB-DFU mode if there is no application flashed to the device or if a button is held down when booting.

Runtime

In runtime mode, it is expected to be running where your main firmware would be. In this mode it can be used to read/write the actual bootloader on the device. This is not a completely risk free process since if you wipe your bootloader and then power cycle you cant boot. But it does mean it can keep running whileever you have power so you can fix it.


Based on the awesome work by https://github.com/davidgfnet/stm32-dfu-bootloader and huge kudos for the framework https://github.com/adamheinrich/cm-makefile. Based on ideas and a lot of work done by @perillamint https://github.com/eDesignOSS/ts100-bl-flasher. This can be thought of as version 2.
