Overview
The GNU ARM Eclipse project includes a set of open source Eclipse plug-ins and tools to create/build/debug/manage ARM (32-bit) and AArch64 (64-bit) applications and static/shared libraries, using the latest GNU ARM GCC toolchains.
ARM family and FPU type
Starting with GNU ARM Eclipse version 2.10.2, from November 2015, full Cortex-M7 support was added to the C/C++ Build → Settings → Tool Settings page; it is now possible not only to select the ARM family: cortex-m7, but also to select the new specific FPU type:
The Hello World Cortex-M C/C++ Project wizard
The project wizard was updated to create generic Cortex-M7 projects.
The STM32F7xx C/C++ Project wizard
And last, but probably the most useful, a new template to create STM32F7 projects was added.
The wizard currently supports STM32F745xx, STM32F746xx, STM32F756xx, and can create blinky projects for the STM32F746_EVAL and STM32F746_DISCOVERY boards.
The created projects not only pass the build, but are ready to run on the selected boards.
