Build a multicore example application {#GUID-8AD8895E-9A3C-4204-B8D9-BC7E80A08168}

This section describes the steps required to configure MCUXpresso IDE to build, run, and debug multicore example applications. The following steps can be applied to any multicore example application in the MCUXpresso SDK. Here, the dual-core version of hello_world example application targeted for the LPCXpresso55S69 hardware platform is used as an example.

  1. Multicore examples are imported into the workspace in a similar way as single core applications, explained in Build an example application. When the SDK zip package for LPCXpresso55S69 is installed and available in the Installed SDKs view, click Import SDK example(s)… on the Quickstart Panel. In the window that appears, expand the LPC55xx folder and select LPC55S69. Then, select lpcxpresso55s69 and click Next.

  1. Expand the multicore_examples folder and select hello_world_cm33_core0. The core1 counterpart project is automatically imported with the core0 project, because the multicore examples are linked together and there is no need to select it explicitly. Then select UART as SDK Debug Console. Click Finish.

  1. Now, two projects should be imported into the workspace. To start building the multicore application, highlight the lpcxpresso55s69_hello_world_cm33_core0 project (multicore master project) in the Project Explorer. Then choose the appropriate build target, Debug or Release, by clicking the downward facing arrow next to the hammer icon, as shown in Figure 3. For this example, select Debug.

The project starts building after the build target is selected. Because of the project reference settings in multicore projects, triggering the build of the primary core application (core0) also causes the referenced auxiliary core application (core1) to build.

Note: When the Release build is requested, it is necessary to change the build configuration of both the primary and auxiliary core application projects first. To do this, select both projects in the Project Explorer view and then right click which displays the context-sensitive menu. Select Build Configurations -> Set Active -> Release. This alternate navigation using the menu item is Project -> Build Configuration -> Set Active -> Release. After switching to the Release build configuration, the build of the multicore example can be started by triggering the primary core application (core0) build.
