CMake manual for Renesas RA boards
The CMake build tool simplifies the build process for development projects. It automatically generates build systems, such as Makefiles and Visual Studio project files.
CMake is a third-party tool with its own documentation. This topic describes how to use CMake with Qt Quick Ultralite when developing applications for Renesas RA boards.
QUL_ROOT and QUL_TOOLS are used in the command line examples below as if they were set as environment variables. For example:
export QUL_ROOT=$HOME/Qt/QtMCUs/2.8.1 export QUL_TOOLS=$HOME/Qt/Tools/QtMCUs
set QUL_ROOT=C:\Qt\QtMCUs\2.8.1 set QUL_TOOLS=C:\Qt\Tools\QtMCUs
Build configuration
Configure the following CMake variables when developing applications for Renesas RA boards.
Setting up a development environment for EK-RA6M3G
Configure the following CMake variables for EK-RA6M3G.
| Variable | Procedure |
|---|---|
| Qul_ROOT | Set the Qul_ROOT to the Qt for MCUs SDK install path.
-DQul_ROOT=$QUL_ROOT -DQul_ROOT=%QUL_ROOT% Note: This CMake variable is intentionally mixed-case because it needs to match the package name. |
| QUL_PLATFORM | Use ek-ra6m3g-baremetal to set up the platform for the EK-RA6M3G board.-DQUL_PLATFORM=ek-ra6m3g-baremetal |
FREERTOS_DIR | Absolute path to the FreeRTOS sources directory. It is required for FreeRTOS targets only. Refer to FreeRTOS platforms for more information about boards on FreeRTOS.-DFREERTOS_DIR=< FreeRTOS directory path > |
| CMAKE_TOOLCHAIN_FILE | Set the CMAKE_TOOLCHAIN_FILE to the Arm GCC or IAR toolchain.
-DCMAKE_TOOLCHAIN_FILE=$QUL_ROOT/lib/cmake/Qul/toolchain/armgcc.cmake -DCMAKE_TOOLCHAIN_FILE=%QUL_ROOT%\lib\cmake\Qul\toolchain\armgcc.cmake |
| QUL_TARGET_TOOLCHAIN_DIR | Use QUL_TARGET_TOOLCHAIN_DIR to set the location for the toolchain.
-DQUL_TARGET_TOOLCHAIN_DIR=/path/to/the/toolchain -DQUL_TARGET_TOOLCHAIN_DIR=C:\path\to\the\toolchain |
| QUL_COLOR_DEPTH | Use QUL_COLOR_DEPTH to set the color depth supported by the platform. The reference port for EK-RA6M3G supports 16bpp color depth.-DQUL_COLOR_DEPTH=16 Note: If this variable is not set, default color depth is used while configuring for the platform. |
| QUL_BOARD_SDK_DIR | Set this variable to the Renesas Flexible Software Package (FSP) install path. For example: -DQUL_BOARD_SDK_DIR=$QUL_TOOLS/Renesas/fsp-<version> -DQUL_BOARD_SDK_DIR=%QUL_TOOLS%\Renesas\fsp-<version> |
| JLINK_PATH | Set the JLINK_PATH CMake cache entry to the SEGGER J-Link installation path if it is not installed in the default location.For example: -DJLINK_PATH=/opt/SEGGER/JLink -DJLINK_PATH=C:\tools\SEGGER\JLink Notes
|
Setting up a development environment for EK-RA8D1
| Variable | Procedure |
|---|---|
| QUL_PLATFORM | Use ek-ra8dm1-baremetal to set up the platform for the EK-RA8D1 board.-DQUL_PLATFORM=ek-ra8dm1-baremetal |
The CMake values for EK-RA6M3G are also valid for EK-RA8D1 apart from the board-specific QUL_PLATFORM variable (ek-ra8dm1-baremetal) and FREERTOS_DIR, which is not valid for EK-RA8D1 as it has only the baremetal platform adaptation.
Note: In a Qt Quick Ultralite project, CMAKE_BUILD_TYPE is set to MinSizeRel by default. MinSizeRel is the build type used for the prebuilt platform libraries shipped with Qt Quick Ultralite. To change the build type (to Release for example), invoke CMake with the -DCMAKE_BUILD_TYPE=Release option. For more information, see CMAKE_BUILD_TYPE.
