This is the documentation for the latest (main) development branch of mcuxpresso sdk. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Linux OS host

The following sections provide steps to run a demo compiled with Arm GCC on Linux host.

Set up toolchain

This section contains the steps to install the necessary components required to build and run a MCUXpresso SDK demo application with the Arm GCC toolchain, as supported by the MCUXpresso SDK.

Install GCC Arm embedded toolchain

Download and run the installer from the GNU Arm Embedded Toolchain Downloads page. The GNU Arm embedded toolchain contains the GCC compiler, libraries, and other tools required for bare-metal software development. The GCC toolchain should correspond to the latest supported version, as described in the MCUXpresso SDK Release Notes for IMX95 Series (document MCUXSDKIMX95SERIESRN).

Add a new system environment variable for ARMGCC_DIR

Create a new system environment variable and name it ARMGCC_DIR. The value of this variable should point to the Arm GCC embedded toolchain installation path. For this example, the path is: $ export ARMGCC_DIR=<path_to_GNUARM_GCC_installation_dir>.

Build an example application

To build an example application, follow these steps.

1. Change the directory to the example application project directory, which has a path similar to the following: <install_dir>/boards/<board_name>/<example_type>/<application_name>/armgcc. For example, the exact path is: <install_dir>/boards/imx95lpd5evk19/demo_apps/hello_ world_sm/armgcc.

2. Run the build_debug.sh script at the command-line to perform the build. The output is shown as below:

   $ ./build_debug.sh
   -- TOOLCHAIN_DIR:
   -- BUILD_TYPE: debug
   -- TOOLCHAIN_DIR:
   -- BUILD_TYPE: debug
   -- The ASM compiler identification is GNU
   -- Found assembler:
   -- Configuring done
   -- Generating done
   -- Build files have been written to:
   Scanning dependencies of target hello_world.elf
   < -- skipping lines -- >
   [100%] Linking C executable debug/hello_world.elf
   [100%] Built target hello_world.elf
   

   Note: build_debug/release.sh are ram target, build_ddr_debug/release.sh are ddr target (only imx95lpd5evk19 hello_world_sm support ddr target this release, the same as iar).
