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 on Windows OS, 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 MCUXpresso SDK Release Notes for EVK-MIMX8ULP (document MCUXSDKIMX8ULPRN).

Note: See How to set up Windows/Linux host system for setting up Windows 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:

C:\Program Files (x86)\GNU Arm Embedded Toolchain\9 2020-q2-update

Reference the installation folder of the GNU Arm GCC embedded tools for the exact pathname.
