Hello there, until now I am building the micropython firmware on a Windows machine running WSL, but many of my students asked me, why they can´t do this on the Windows system itself, although the ESP-IDF system on Windows works quite well (or at least reasonably well). The first problem I ran into w...

Hello, I am wondering how to exclude classes from the Micropython Firmware to get a smaller footprint for the ESP32 port. For me, it is more of a way to dive deeper into Micropython. But it seems to be very hard to find out the build sequence. I am not so familiar with cmake and there are a number o...

Hi Robert, thanks for your fast response. That explains a lot. I have flashed my Pi Picos several times and there was no change in my filesystem, but then I have done the same on an ESP32 and all my files are gone.

Hello there, I have a simple question, but I can´t find an answer. I wonder if there is a way to flash a board with a new firmware without overwriting the existing filesystem. Thank a lot an best regards, Werner

Hi Dave,
again you are my angel of Salvation

Thanks a lot!

Hello, in the source code of the stm32 port there are servo.h and servo.c files in the root directory of this port. But when I compile it I can´t import it. I have tried various possible ways: from Servo import servo from pyb import Servo and some other variations. I have listed all importable modul...

Dear Dave,

sorry for the long delay, but I checked it today and it works fine. Thank you very much for your support.

Best regards,
Werner

Hi Dave, long time ago (normally a good sign :mrgreen: ) but now I have tried the way you proposed. I have typed in the command as you do but I got the following error message: server:~/micropython/tools$ python3 dfu.py -d NUCLEO_L476RG-20200902-v1.13.dfu File: "/mnt/c/Users/werner/OneDrive/microPyt...

Hi Dave, thanks a lot. When I make my own build it works fine, because I got all binary formats I need (.bin, .hex and .dfu) But I am looking for a simple way to upload the firmware for my students. They use the binary download files on the Micropython page. So they only got the .dfu version and the...

Hi there, I have been using the dfuse-demo (STSW-STM32080) for converting the dfu files into bin- oder hex-files but it is replaced by STM32CubProgrammer and this tool doesn´t offer dfu-to-bin-conversion, also the STSW-STM32080 only works on Windows. So is there an alternative for the old dfu file m...
