Hello, some time ago I started to play with CortexM4,

I bought a Discovery Board with a STM32F407VG in order to be programmed with uVision from Keil.

I am developing a project where the money is very restricted, that's why I was using a free licence from…

I'm using the gcc toolset, and had hoped to be able use this functionality, however all of the documentation seems to state superseded or suspended.

ARM Information Center

I'm trying to target an STM32F4 processor.

Any pointers to how to do this…
