Arduino for STM32

Hello.
I've chosen this board for her little size, flash 1MB, CAN bus, FPU and frequency 168MHz ...
Flash with Arduino_STM32-master is correct with STLink key and "Generic STM32F407VE series" type of board.

Pin's affectation is different than BlackF407VE ( ie in board LED is on PE0), but the scheme is very simple.
I would, now optimize the use on 2 domains :
** 1 - As BlackF407VE, how enable the FPU ? In the sketch ? by libraries ? pre-compilation ? ...
** 2 - 1MB is good ... but BlackF407VE board.txt limit the code flash to 512KB. How can i use the totality of flash memory ?
Naturally, i know that STM32Cube make job but i prefer use Arduino IDE ...

Nice to read you.

Hi,
The DIYmore STM32F407VGT6 is directly supported with STM32 core 2.0.

Just select it directly in the list of boards.

Hello, AndrewBCN.
Thank you for your tip. But i've Roger's core, no official core made by STM.
And before install official core, i would try one another PC for tests. After, if it's not too heavy, why not ...
Is DIYmore STM32F407VGT6 likely familiar with "generic STM32F407V mini-series" named in Roger's core ? ( it's for 1Mb flash !!!)
