PyBoard firmware update using Windows PC

Development Boards Other Microcontrollers
1

I recently bought a PyBoard v1.1 via Mouser, it is Sparkfun type DEV-14413. It came with firmware “MicroPython v1.10 on 2019-01-25”. I would like to update to the latest fw, that is v1.11. Can you point me to the best instructions how to do the trick? My tools are Windows 7 and 10, no Linux machines available at the moment.

Reading thru various forums, I can see people having lots of problems here. I understand the “STM32CubeProgrammer” might be the latest and thereby the preferrable tool from ST to do the flashing. The forums mostly talk about other flasher tools but those discussions are a couple of years old.

Which tool do you use when producing the DEV-1441x boards?

Thanks for your help.

Hi Tom.

SparkFun doesn’t make the pyboard v1.1, we just resell this item. I did find a link that might help you with upgrading the firmware though.

    Hi Chris

    Thanks for your answer. I had gone to GitHub already, but ended here “The documentation is out of date, but DfuSe is easy to use for reprogramming without the documentation.”

    Wondered if there was some instructions for using the STM32CubeProgrammer tool.

    Can you perhaps point me to the PyBoard maker?

    Hello Tom.

    MicroPython makes the pyboard.I don’t have any instructions for using the STM32CubeProgrammer tool, but you might be able to get help from MicroPython on that. The link below will direct you to their contact page.
