Installation

A quick walkthrough for setting up this tool using a Python Virtual Environment, to prevent polluting your Python installation. Example command line inputs shown for a Windows Powershell session.

1. Download or clone this repo.

2. Create a new virtual environment in .venv.

    python -m venv .venv
   

3. Activate the virtual environment (if not done automatically).

    .\.venv\Scripts\activate
   

4. Install modules from the requirements.txt file using pip.

    pip install -r requirements.txt
   

5. Done. Remember to activate the .venv when running the tool in a new shell session.

Usage

1. Compile the NEORV32 binary and generate a bootloader image file (example sw use "make exe").

2. Prepare the command line to launch this tool (bootloader timeout may be too short to enter it later)

    .\neorv32load.py <serial_port> <path_to_.bin_file>
   

3. Reset the Target to enter the bootloader.

4. Execute the prepared command line inputs.

Other options are listed in the included help output. Use the following command to access it:
