This Python script should be compatible with Python 2 & 3. I have tested it on Windows and Linux, but not OSX. Python 3 is preferred.
This Python script will automatically open all USB serial ports which match the VID & PID of a CP2012N. We've tested this with up to ten programmers at a time.
For all open ports, it will continuously attempt to flash a Swadge using esptool.
The UI will flash green for four seconds when a Swadge is successfully flashed. It will flash red if the flash failed.
The following Python modules must be installed:
python3(https://www.python.org/downloads/)tkinter(https://tkdocs.com/tutorial/install.html)pyserial(https://pyserial.readthedocs.io/en/latest/pyserial.html orpip install pyserial)esptool(this dependency was replaced with a local version with bugfixes, no install necessary)
For the script to actually flash firmware, the following files must be in the same directory as pyFlashGui.py:
image.elf-0x00000.bin(from compilation)image.elf-0x10000.bin(from compilation)blank.bin(from ESP8266_NONOS_SDK/bin)esp_init_data_default_v08.bin(from ESP8266_NONOS_SDK/bin)
- Download and install the dependencies
- Download the final Swadge firmware from the Releases tab: https://github.com/AEFeinstein/Super-2020-Swadge-FW/releases/download/2.0.0/Super_2020_Swadge_FW.zip
- Plug in your programmer with a microUSB cable
- Run the programmer script (
python3 pyFlashGui.pyfrom a terminal) - Switch the programmer to "ON" and "5V"
- Hold down the "GPIO0" button and plug in your Swadge
- Wait for the GUI to flash green, then you're done.
We also sent a video to the manufacturer about how to flash Swadges with test firmware: https://youtu.be/LsFIoCyYO6w
