Cross-compile for Cortex-M7 under Windows

[KonradFoit]

Hi!

I've been trying to compile micropython for STM32F7 (STM32F746 discovery to be precise) under Windows, but with no luck.
I have cygwin, gcc-toolchain that supports Cortex-M7, but when i try to compile I get this error:

Create build-STM32F7DISC/genhdr/pins.h
python boards/make-pins.py --board boards/STM32F7DISC/pins.csv --af boards/stm32f746_af.csv --prefix boards/stm32f4xx_prefix.c --hdr build-STM32F7DISC/genhdr/pins.h --qstr build-STM32F7DISC/pins_qstr.h --af-const build-STM32F7DISC/genhdr/pins_af_const.h --af-py build-STM32F7DISC/pins_af.py > build-STM32F7DISC/pins_STM32F7DISC.c
Makefile:337: recipe for target 'build-STM32F7DISC/genhdr/pins.h' failed
/usr/bin/sh: python: command not found
make: *** [build-STM32F7DISC/genhdr/pins/h] Error 127

Any hints what to do?

Best regards,
Konrad

I have Python 2.7.11

But apparently, its not in your path. If you're building using cygwin, then you'll need to install the cygwin version of python.

OK. Problem solved.
Python added wrong directory to PATH for some strange reasons.

Is there a ready to code python Cortex M7 solution, including the board (featuring WLAN WPS, SSL...)?
thanks

There is the beginnings of a port to the STM32F7DISC (Discovery board), but the ethernet and LCD hasn't been supported yet.
