Hi everyone,

I am trying Visual Studio 2015 + VisualGDB and I think it is pretty good! I tried a many of IDEs like: CooCox, Atollic, OpenSTM… but I really like VS platform. Everything works fine but I want to ask a question about changing a toolchain in created project. Actual toolchain has 5.3 GCC version, but sometimes I want/have to compile and link my project with older GCC version (for example GCC 4.9.x what I am using in CooCox). I found some information that I have to edit stm32.mak – which I eddited like this:

<hr />

#VisualGDB provides BSP_ROOT and TOOLCHAIN_ROOT via environment when running Make. The line below will only be active if GNU Make is started manually.
BSP_ROOT ?= $(LOCALAPPDATA)/VisualGDB/EmbeddedBSPs/arm-eabi/com.sysprogs.arm.stm32
EFP_BASE ?= $(LOCALAPPDATA)/VisualGDB/EmbeddedEFPs

TOOLCHAIN_ROOT ?= C:/Install/GCC 4.5.2/arm-gcc/arm-none-eabi

CC := $(TOOLCHAIN_ROOT)/bin/gcc.exe
CXX := $(TOOLCHAIN_ROOT)/bin/g++.exe
LD := $(CXX)
AR := $(TOOLCHAIN_ROOT)/bin/ar.exe
OBJCOPY := $(TOOLCHAIN_ROOT)/bin/objcopy.exe

#Additional flags
PREPROCESSOR_MACROS += ARM_MATH_CM4 STM32F407VE
INCLUDE_DIRS += .
LIBRARY_DIRS +=
LIBRARY_NAMES += compactcpp
ADDITIONAL_LINKER_INPUTS +=
MACOS_FRAMEWORKS +=
LINUX_PACKAGES +=

CFLAGS +=
CXXFLAGS +=
ASFLAGS += -mfpu=fpv4-sp-d16
LDFLAGS +=
COMMONFLAGS += -mcpu=cortex-m4 -mthumb -mfloat-abi=soft
LINKER_SCRIPT := $(BSP_ROOT)/STM32F4xxxx/LinkerScripts/STM32F407VE_flash.lds

<hr />

Later I found that I have to edit stm32.xml file too, but I do not know how.

Is there some way? Could you give me some guide? Thank you very much!
