I want at the end micro python which consists only of the UART repl and the necessary files for Python.

Ok thanks for the tip. Let's see how much I can still reduce to nothing more goes

The strip down method was better for me. Yielded faster results. My reduced MicroPython: - /tools - /extmod - /lib - /py - /stmhal * bufhelper * extint * gccollect * gchelpers.s * irq * main * Makefile * make-stmconst.py * modpyb * modstm * modstmconst.gen.c * moduselect * mpconfigport.h/.mk * mphal...

Hello everyone, In my try to understand MicroPython(is an still ongoing process :? :?: ) i reduced the whole MicroPython project to the minium. Only Repl running over UART (no USB driver, leds, pins, spi, i2c,...) on the pyBoard. For me it's the best starting point to port MicroPython to another tar...

Hello, At the time you can flash micropython on the STM32F429i with the build-enviroment of the "STM32F4DISCO". Problem is that the USB_OTG connector "CN6" is currently not working, so you have no access to micropython over USB. But you can set in the main.c a UART-instance for the REPL prompt. Furt...

Little update,...
The STM32F429 discovery firmware package included libraries for the USB_OTG_HS, this is the right track.

I try to integrate the libraries....i report back soon.

Thanks for the quick answers, blmorris. Exactly i will use the combined FS/HS (USB-HS) controller (CN6) in Full-Speed-Mode for the repl and CN1 for power supply / firmware upgrade (ST-Link/V2) Currently running MicroPython at the F429i with many modules (LED,PWM,UART,... and a repl-prompt via UART)....

okay, so HS is not supported without an external transceiver. For my understanding: Therefore at the line 97 in /stmhal/usbd_conf.c is the HS-config for other targets how has USB-HighSpeed support, right? The pyboard uses the FS-config starting at line 57 (stmhal/usbd_conf.c), declared in /stmhal/bo...

Hallo again ,

I have changed the USB port configuration in /stmhal/usbd_conf.c for the USB_OTG_FS.

My Question is, in which file will set the variable ``hpcd->Instance``?
Or is decided by the driver, whether HighSpeed or FullSpeed?

thanks

Okay thanks I try it. Back to my thread headline "Firmware flashing methods". I try to explain it..... Firmware.dfu ( D evice F irmware U pgrade) -> is converted from the Firmware.elf and can be flashed to pyboard over DFU-UTIL (some posts above explained). Firmware.elf ( E xecutable and L inkable F...

Thanks Bryan, After I now again a little deeper into MicroPython, I can confirm the acceptance. Now I try to rebuild step by step MicroPython for the pyBoard with the minimal-directory. I guess that's the best way to get an idea how MicroPython works for a later porting to another MCU. Or have anybo...
