8-Bit Microchip Device Firmware Update (MDFU) Solution for the PIC16F18446 Curiosity Nano Evaluation Kit

Introduction

This repository contains two configurations to showcase the utilization of the 8-Bit MDFU Client library in creating an efficient development ecosystem within MPLAB® X.

Each of these configurations contains two MPLAB® X projects: the bootloader client project and the application project.

1. Basic Bootloader Client Example Using UART
2. Bootloader Client Example Using UART With Multiple Image and Anti-Rollback Support

Software Used

• MPLAB® X IDE 6.25 or newer
• XC8 Compiler
• Avr-GCC Compiler
• MCC Core v5.8.2 or later
• MCC Melody Core v2.9.1 or later
• MCC Melody 8-Bit MDFU Client
• Python v3.8 or later
• pyfwimagebuilder v1.0.1.14 or later
• pymdfu v2.5.1.9

Hardware Used

• PIC16F18446 Curiosity Nano Evaluation Kit
• USB-A to USB Micro B cable

Hardware Setup

Connect the PIC16F18446 Curiosity Nano Evaluation Kit to the PC using the USB-A to UBS Micro B.
