Currently I'm using an "include" of the toolchain file prior to calling "project" since 100% of development happens on a PC instead of having to pass the CMAKE_TOOLCHAIN_FILE option every time. Here's the contents: set(CMAKE_SYSTEM_NAME Generic) set(CMAKE_SYSTEM_PROCESSOR arm) set(CMAKE_SYSTEM_VERSION 1) # specify the cross compiler set(CMAKE_C_COMPILER arm-none-eabi-gcc) set(CMAKE_CXX_COMPILER arm-none-eabi-cpp) set(CMAKE_EXE_LINKER_FLAGS "-T${CMAKE_SOURCE_DIR}/stm32_flash.ld") set(CMAKE_EXECUTABLE_SUFFIX_C ".elf") set(CMAKE_EXECUTABLE_SUFFIX_CXX ".elf") set(CMAKE_EXECUTABLE_SUFFIX_ASM ".elf") # Macro for elf->bin macro(elf2bin target) add_custom_command(TARGET ${target} POST_BUILD COMMAND ${CMAKE_OBJCOPY} -O binary ${target}.elf ${target}.bin COMMENT "Creating binary for ${target}") endmacro() Thanks, Richard
