# Command-line Setup for Renesas Boards

Assuming that the prerequisites are installed, the following subsections provide instructions to set up your environment using the command line.

Note: This page uses QUL_ROOT and QUL_TOOLS in command line examples as if they were set as environment variables. They could be set for example:

export QUL_ROOT=$HOME/Qt/QtMCUs/2.0.0 export QUL_TOOLS=$HOME/Qt/Tools/QtMCUs
set QUL_ROOT=C:\Qt\QtMCUs\2.0.0
set QUL_TOOLS=C:\Qt\Tools\QtMCUs

Warning: Buiding with the Ninja generator fails with incremental builds on GHS. It is recommended to use NMake Makefiles or NMake Makefiles JOM. If Ninja generator is still used CMake will display a warning.

## Build configuration

Configure the following CMake variables. For more information, see the CMake Manual.

VariableValue
Qul_ROOTSet the Qul_ROOT to the Qt for MCUs SDK install path.
-DQul_ROOT=%QUL_ROOT%

Note: This CMake variable is intentionally mixed-case since it needs to match the package name.

QUL_PLATFORMThe platform must be set to the corresponding board and the OS you plan to use. Use the ek-ra6m3g-baremetal or rh850-d1m1a-baremetal depending on your hardware.
-DQUL_PLATFORM=rh850-d1m1a-baremetal
CMAKE_TOOLCHAIN_FILESet it to the appropriate toolchain configuration file. For RH850-D1M1A, set it to GHS toolchain, and for EK-RA6M3G, set it to Arm GCC or IAR toolchain.

#### Windows host:

-DQUL_BOARD_SDK_DIR=C:\Renesas_Electronics\D1x_RGL\rgl_ghs_D1Mx_obj_V.2.0.0a
RENESAS_FLASH_PROGRAMMER_PATHSet the optional RENESAS_FLASH_PROGRAMMER_PATH CMake cache entry to the Renesas Flash Programmer installation path. For example:

#### Windows host:

-DEK_RA6M3G_E2_PROJECT_PATH=C:\Users\<user>\e2_studio\workspace\<project_name>
JLINK_PATHSet the JLINK_PATH CMake cache entry to the SEGGER J-Link installation path if it is not installed in the default location. For example:

#### Linux host:

-DJLINK_PATH=/opt/SEGGER/JLink

#### Windows host:

-DJLINK_PATH=C:\tools\SEGGER\JLink

Note: Ensure that the entry value does not contain spaces.

Flash targets are created if the J-Link software kit is found.

Note: in a Qt Quick Ultralite project the CMAKE_BUILD_TYPE CMake argument is by default set to MinSizeRel. MinSizeRel is the build type used for the pre-built platform libraries shipped with Qt Quick Ultralite. If you want to change the build type (e.g. to Release) you can do so by invoking cmake with -DCMAKE_BUILD_TYPE=Release. Please refer to this page for more information.

## Building applications with prebuilt Qt Quick Ultralite libraries

The following command builds the minimal example for EK-RA6M3G:

cd $QUL_ROOT/examples/minimal mkdir build cd build cmake .. -G "Ninja" -DCMAKE_BUILD_TYPE=MinSizeRel -DQul_ROOT=$QUL_ROOT -DCMAKE_TOOLCHAIN_FILE=$QUL_ROOT/lib/cmake/Qul/toolchain/armgcc.cmake -DQUL_TARGET_TOOLCHAIN_DIR=$QUL_TOOLS/arm_gcc_10 -DQUL_PLATFORM=EK-RA6M3G-baremetal -DQUL_BOARD_SDK_DIR=\$QUL_TOOLS/Renesas/fsp-2.0.0 -DJLINK_PATH=/opt/SEGGER/JLink
cmake --build .
cd %QUL_ROOT%\examples\minimal
mkdir build
cd build
cmake --build .
Once you have successfully built the minimal example application, use the following command to flash it:
cmake --build . --target flash_minimal
