Compiling for a personalized card STM32F407VGT6

[Krasn4ck]

Hello.
I am trying to compile MicroPython version 1.14 on a custom board with STM32F407VGT6, I have all the compile files needed to compile are as follows:

• mpconfigboard.h

• mpconfigboard.mk

• pins.csv

• stm32f4xx_hal_conf.h

I put the folder of these files in the path /ports/stm32/boards/ but I get the following error when I try to compile:

Code: Select all

Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
make: *** No rule to make target 'build-OPHYRA/genhdr/pins.h', needed by 'build-OPHYRA/py/mpstate.o'.  Stop.

This is the command I am using to perform the compilation:

Code: Select all

make -j2 BOARD=OPHYRA

I am using Cygwin to perform the compilation process
Thank you very much if you can give me any guidance as to what the problem is with this error.

Update, now have this issue:

Code: Select all

 make BOARD=OPHYRA
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

Update, now have this issue:

How did you fix the first issue?

Are you able to successfully build other boards? For example the OLIMEX_F407 is a good test as it uses the same MCU.

Hi Jimmo with OLIMEX_F407 I had no problem, now I simply corrected this error, but now I got this one:

Can you put a copy of the OPHYRA board directory somewhere (e.g. on github) ?
