error when processing make BOARD=BLACK_F407VE

[pierrebak]

I have this error while trying to establish the definition:

make: *** no rule to make the target « lib/mbedtls/library/aes.c », necessary forre pour « build-BLACK_F407VE/genhdr/qstr.i.last ». Stop.

Same error here

Solved with first following the guidelines in https://github.com/micropython/micropython
Steps are:

$ sudo apt install gcc-arm-none-eabi
$ git clone https://github.com/micropython/micropython.git
$ cd micropython/mpy-cross
$ make
$ cd ../ports/stm32
$ make submodules
$ cd boards
$ git clone https://github.com/mcauser/BLACK_F407VE.git
$ cd ..
$ make BOARD=BLACK_F407VE

Then flash the board in DFU:

$ make BOARD=BLACK_F407VE deploy

I flashed using the following:

$ sudo apt install dfu-util
$ sudo dfu-util -a 0 -D build-BLACK_F407VE/firmware.dfu

Thanks, LouDnl (and mcauser, of course!)
Your solution worked for me as well on a raspberry pi 4. The dfu-util command worked whereas 'make BOARD=BLACK_F407VE deploy' failed with:
