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 EVK-MIMX8ULP (document MCUXSDKIMX8ULPRN).

Note: See How to set up Windows/Linux host system for setting up Linux host before compiling the application.

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 this example, the exact path is: <install_dir>/boards/evkmimx8ulp/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: To run the application, see the Run an application using imx-mkimage.
