CircuitPython on a PyBoard 1.1 How to install?

by BiffMcFly on Sat Feb 29, 2020 7:06 am

Can anyone help me out on how to install CircuitPython on a PyBoard?
I Have the .Bin file but the loader only accepts .dfu files.

Thank you

Hi there! I was able to load Circuitpython 5.3.0 on the PyboardV1_1 which previously had Micropython.

I used the instructions for the Feather Express with the STM32F405, which is similar to the Pyboard V1.1:

https://learn.adafruit.com/adafruit-stm32f405-feather-express/dfu-bootloader-details

This is what I did.
First, download the binary file for Circuitpython:

https://circuitpython.org/board/pyboard_v11/

Then download the STM32CubeProgrammer software for programming the Pyboard and install:

https://www.st.com/en/development-tools/stm32cubeprog.html

I then found the 3v3 and Boot pins which are beside each other (lower left corner, second row up if usb pointed up) and jumpered them, powered up the Pyboard using a USB cable with a Windows computer, and followed the instructions for STM32CubeProgrammer as detailed for the Feather.

The jumper placement is shown on page 6 in this guide:

I am now running 'Adafruit CircuitPython 5.3.0 on 2020-04-29; PyboardV1_1 with STM32F405RG' as per PuTTy.

I hope this helps!

Mike.
