GnWManager

GnWManager is THE game-and-watch device manager. GnWManager is a command line tool who's responsible for getting firmware onto your device, managing the filesystem, and other device administrative tasks.

GnWManager accomplishes this via a small bundled pre-compiled firmware that gets executed from the STM32's RAM.

Features

• Standalone and simple to install.
  • No more installing many different tools with various patches!
• Fast internal and external flash firmware flashing.
  • Hardware-accelerated hashing for rapid duplicate discovery.
    • Only syncs changed data.
    • Minimizes flash erases and writes, extending flash lifespan.
  • Double buffered, asynchronous, LZMA-compressed transfers for maximum speed.
• Complete filesystem management.
  • Backup and restore files.
  • Interactive filesystem explorer.
• Automatic Real-Time-Clock (RTC) configuration.
• Developer tools:
  • Easily monitor device printf statements and launch GDB sessions.
  • Capture screenshots, regardless of the running firmware.

Installation

It is highly recommended to use pipx to install GnWManager.

pipx install gnwmanager

That's it!

Updating

Update GnWManager as you would any python command line tool installed by pipx:

pipx upgrade gnwmanager

Compatibility

GnWManager works with all major operating systems: Windows, Mac, and Linux. GnWManager is also compatible with the following probes:

1. Raspberry Pi Pico (Recommended)
2. STLink
3. JLink
4. DAPLink (~10x slower than other probes)

Unfortunately, GnWManager is not compatible with raspberry pi gpio. There is currently an effort to add support in pyocd, the underlying library that GnWManager uses for hardware interactions.

STLink

Hook up your STLink to your game and watch as follows:

Raspberry Pi Pico

All Raspberry Pi Picos can be transformed into programmers via the picoprobe project.

1. Download picoprobe.uf2 from picoprobe releases.
2. Hold BOOT button on the pico and plug it into the computer. It should show up as a USB drive. Drag and drop picoprobe.uf2 to it.
3. Hook up the 3 wires (GND, GP2, GP3) to (GND, SDCLK, SWDIO), respectively.
