This repository contains tool that allows you to create a backup copy of bootloader from your MKS Robin board (STM32F103ZET6). Backup copy of bootloader can be used to return original board's functionality after you had program board with an alternative firmware.
The 'Robin' directory contains PlatformIO project with custom scripts that are required to make MKS Robin-compatible encrypted firmware. During final stage of build process the 'firmware.bin' file is encrypted and saved as 'Robin.bin' that can be used with built-in bootloader.
