Linux OS host

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/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 support ddr target this release, the same as iar).
