Not dependent on MCUXpresso's IDE or VS Code extension. Also independent of dev board definitions and SDK example code files. Prerequisites: What do you need: working CMake and ARM GCC toolchains a downloaded and unzipped SDK (check if this link works - NXP account needed) MCUXPresso Config tools ( link , NXP account needed) a .mex configuration file for your project. If you use shabaz' EZ-MCXN dev board , get it from his GitHub repo . a main file (example below) a CMake config file, the main focus of this post. CMake file I'll go start to end over the file. Check the inline comments Initialisation This step sets standards, and some definitions that are needed early on. cmake_minimum_required(VERSION 3.29) set(CMAKE_VERBOSE_MAKEFILE OF) set(CMAKE_C_STANDARD 11) set(CMAKE_CXX_STANDARD 26) set(CMAKE_CXX_STANDARD_REQUIRED ON) # SDK_ROOT set externally set(SDK_ROOT $ENV{SDK_ROOT}) # set as a CMake Environment variable. Points to root of unzipped SDK message(STATUS "SDK_ROOT: ${SDK_ROOT}") set(CMAKE_SYSTEM_NAME Generic) # no OS set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} --specs=nosys.specs") # prevents CMake throws toolchain error when using embedded GCC add_compile_definitions( MCXN236 # controller CPU_MCXN236VKL # package ) Fetch debug configuration, in case you want to use a hardware debugger later. Only runs if needed. Either at first run, or if the cache is cleaned. First run needs an internet connection. If you don't plan to use a hardware debugger, you can safely comment this section. include(FetchContent) set(FETCHCONTENT_QUIET FALSE CACHE BOOL "" FORCE) # show download, because it takes a while set(FETCHCONTENT_UPDATES_DISCONNECTED ON CACHE BOOL "" FORCE) # skip if we have it in cache. Also allows for offline builds FetchContent_Declare(svd # get MCXN236 svd definition, so registers are available during debug GIT_REPOSITORY "https://github.com/nxp-mcuxpresso/mcux-soc-svd.git" GIT_TAG origin/main GIT_PROGRESS TRUE # show download, because it takes a while # prevent makefile execution (if any) SOURCE_SUBDIR = ) FetchContent_MakeAvailable(svd) file(COPY "${svd_SOURCE_DIR}/MCXN236/MCXN236.xml" # copy svd from download to build dir, where launch.json can find it DESTINATION "${CMAKE_BINARY_DIR}" ) Generate CMUXpresso Config source files This is called, during Build, only when needed. Either if the source files don't exist yet (first build, files removed), or if they are older than the .mex file. It checks that for Pins, Clocks and Peripherals. The required jobs will run in parallel. Because my project doesn't use the peripherals (the source files aren't added to the build target), CMake knows that it can skip the Peripherals .h and .c file generation. # MCUXpresso Config section set(CONFIG_TOOL_PATH $ENV{CONFIG_TOOL_PATH}) # check if MCUXpresso Config path is set if(CONFIG_TOOL_PATH) # path set: generate sources message(STATUS "CONFIG_TOOL_PATH: ${CONFIG_TOOL_PATH}") set(MEX_FILE "${CMAKE_CURRENT_SOURCE_DIR}/EZ_MCXN.mex") set(OUTPUT_DIR "${CMAKE_CURRENT_SOURCE_DIR}") message(STATUS "MCUXpresso Config Tools: source-export (Pins, Clocks, Peripherals)...") # Check if needs to run: Pins set(PINS_DEST_HEADER "${OUTPUT_DIR}/board/pin_mux.h") set(PINS_DEST_SOURCE "${OUTPUT_DIR}/board/pin_mux.c") add_custom_command( OUTPUT "${PINS_DEST_HEADER}" "${PINS_DEST_SOURCE}" COMMAND "${CONFIG_TOOL_PATH}" "-noSplash" "-consoleLog" "-HeadlessTool" "Pins" "-Load" "${MEX_FILE}" "-ExportSrc" "${OUTPUT_DIR}" RESULT_VARIABLE CONFIG_TOOL_RESULT ERROR_VARIABLE CONFIG_TOOL_ERROR DEPENDS "${MEX_FILE}" COMMENT "Generating Pins files because ${MEX_FILE} changed or board files are missing" VERBATIM ) # Check if needs to run: Clocks set(CLOCKS_DEST_HEADER "${OUTPUT_DIR}/board/clock_config.h") set(CLOCKS_DEST_SOURCE "${OUTPUT_DIR}/board/clock_config.c") add_custom_command( OUTPUT "${CLOCKS_DEST_HEADER}" "${CLOCKS_DEST_SOURCE}" COMMAND "${CONFIG_TOOL_PATH}" "-noSplash" "-consoleLog" "-HeadlessTool" "Clocks" "-Load" "${MEX_FILE}" "-ExportSrc" "${OUTPUT_DIR}" RESULT_VARIABLE CONFIG_TOOL_RESULT ERROR_VARIABLE CONFIG_TOOL_ERROR COMMAND ${CMAKE_COMMAND} -E rename "${OUTPUT_DIR}/cm33_core0/board/clock_config.h" "${CLOCKS_DEST_HEADER}" COMMAND ${CMAKE_COMMAND} -E rename "${OUTPUT_DIR}/cm33_core0/board/clock_config.c" "${CLOCKS_DEST_SOURCE}" COMMAND ${CMAKE_COMMAND} -E remove_directory "${OUTPUT_DIR}/cm33_core0/board" COMMAND ${CMAKE_COMMAND} -E remove_directory "${OUTPUT_DIR}/cm33_core0" DEPENDS "${MEX_FILE}" COMMENT "Generating Clocks files because ${MEX_FILE} changed or board files are missing" VERBATIM ) # Check if needs to run: Peripherals set(PERIPHERALS_DEST_FILE_1 "${OUTPUT_DIR}/board/peripherals.h") set(PERIPHERALS_DEST_FILE_2 "${OUTPUT_DIR}/board/peripherals.c") add_custom_command( OUTPUT "${PERIPHERALS_DEST_FILE_1}" "${PERIPHERALS_DEST_FILE_2}" COMMAND "${CONFIG_TOOL_PATH}" "-noSplash" "-consoleLog" "-HeadlessTool" "Peripherals" "-Load" "${MEX_FILE}" "-ExportSrc" "${OUTPUT_DIR}" RESULT_VARIABLE CONFIG_TOOL_RESULT ERROR_VARIABLE CONFIG_TOOL_ERROR DEPENDS "${MEX_FILE}" COMMENT "Generating Peripherals files because ${MEX_FILE} changed or board files are missing" VERBATIM ) else() # path not set: developer should generate sources with GUI message(STATUS "CONFIG_TOOL_PATH not set.
