This document describes how to update the version of the SimpleLink SDK that a Code Composer Studio project is using.

Separate Kernel Project

By default SimpleLink SDK projects are dependent on a separate "kernel" project. This section describes how to change the SDK version when a kernel project is present.

When working with the SimpleLink SDK there are multiple projects present. One project contains the application and another project contains the kernel. It is the kernel project that we need to modify to change the SDK version used. In the image below the "tirtos_builds_MSP_EXP432P401R_release_ccs" project is the kernel project.

Select the kernel project in the Project Explorer view. Open the context menu and select properties. Right-click to open the context menu on Windows or Linux, on Mac use Control-click. This will open the properties dialog for the project. Select General in the tree on the left and then select the RTSC tab on the right as shown in the image below.

The RTSC tab displays all of the products and versions that Code Composer Studio is aware of. If you have installed a new version of the SDK via Resource Explorer, or by downloading and installing it manually, it will show up in this list. You can expand a product and select the specific version that you want to use.

Sometimes when upgrading the SDK it will be necessary to also change the version of the XDCTools that are used as part of the build process. The release notes for the new version of the SDK will indicate if this is necessary. The change can be performed here.

Click OK to save the changes. Now perform a Rebuild of kernel project and it will be using the new version of the SDK. Note that when the kernel project is rebuilt that this will take a couple of minutes.

Single Project Scenario

These steps apply if no separate kernel project is present and instead the RTOS configuration is present in the application project.

Select your project in the Project Explorer view. Open the context menu and select properties. Right-click to open the context menu on Windows or Linux, on Mac use Control-click. This will open the properties dialog for the project. Select General in the tree on the left and then select the RTSC tab on the right as shown in the image below.

If you are upgrading from a version of the SDK 1.40 or older to a version greater than 1.40 you will also need to add ${COMPILER_FLAGS} to the advanced settings for the XDC Tools.

Click OK to save the changes. Now perform a Rebuild of project and it will be using the new version of the SDK.
