How to change toolchain to common gcc

[marosdurik]

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!

Hi,

We have added this feature to the v5.2 version. Please try the latest VisualGDB 5.2 Beta 2. You can switch the toolchain on the Makefile Settings page of your VisualGDB Project Properties.

Hi, thank you very much for your response. I will try it.

But could you (only for my interest) tell me how can I switch it manually in my version GDB?

Hi,

You can do that by creating another project with the new toolchain and copying the ToolchainID value from its stm32.xml file to the old project’s stm32.xml.
