J-Link Firmware Loader

This repository contains two versions of a Tkinter-based application for loading firmware onto an XMC4700-2048 microcontroller using a J-Link device. One version uses the subprocess module to interact with J-Link Commander, and the other uses the pylink library.

Features

• Select firmware file via file dialog
• Load firmware onto XMC4700-2048 at 4000 kHz speed in SWD mode
• Display success or error messages in a message box

Requirements

• Python 3.6+
• tkinter (usually included with Python)
• pylink-square (for the pylink version)
• pyinstaller (for building executables)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/jlink-firmware-loader.git
   cd jlink-firmware-loader

2. Install the required Python packages:

   pip install pylink-square
   pip install pyinstaller

Usage

Running the Application

You can run either version directly with Python:

• Subprocess Version:

  python subprocess_jlink_loader.py

• Pylink Version:

  python pylink_jlink_loader.py

Building Executables

Batch files are provided to build standalone executables using pyinstaller:

• Build Subprocess Version:

  build_subprocess_jlink_loader.bat

• Build Pylink Version:

  build_pylink_jlink_loader.bat
