Hi,
Bellow you can find the necessary steps to enable SDK components when using GitHub SDK and Kconfig/CMake. This procedure is helpful for creating custom example applications that combine multiple SDK components..
Prerequisites:
- VS code: https://code.visualstudio.com/
- MCUXpresso plugin: https://www.nxp.com/design/design-center/software/development-software/mcuxpresso-software-and-tools...
- Getting started with MCUXpresso for VS Code: https://www.nxp.com/design/design-center/training/TIP-GETTING-STARTED-WITH-MCUXPRESSO-FOR-VS-CODE
Step 1:
Make sure that all SDK tools are up to date. For this, open the MCUXpresso Installer tool and click on the "Check for newer versions of components" button.
Check that the MCUXpresso SDK Developer tools collection has a green checkmark next to it. Otherwise click on it to select it and after that click Install to update/install the package to it's latest version.
Step 2:
Use the import example application tool to import the base example that you want to modify for the board you are working with.
Step 3:
Method 1: Editing the example prj.conf file
Once the project is imported you can see through "Project files" a file called "prj.conf" that contains example specific flags to set certain variables or enable specific SDK components .
Here you can set the flags needed by the component/driver/middleware you wish to enable for your project. To see what flags are needed by a specific component you can check the component Kconfig file:
- For drivers go to ../mcuxsdk/drivers/<driver-name>/Kconfig
- For components go to ../mcuxsdk/components/<component-name>/Kconfig
- For middleware go to ../mcuxsdk/middleware/<middleware-name>/Kconfig
To search for a specific component or driver you can use the "Jump to.." button and type in the name of the component/driver and click search to list all available references:
To enable a component, simply check it inside any window and click on Save in the main window of the tool after making your modifications.
Step 4:
Rebuild the project with the new config to check for any incompatibilities. Right click on the project and select "Pristine Build/Rebuild the project" to perform a clean build of the project with the new configuration.
Note: Check the build logs to see any error/warnings of incompatibility between the components you have enabled previously.
For example trying to just enable the ehternet driver on a project without it's dependencies can cause the following warning that is easy to oversee but will result in the component not being actually activated and the project facing build errors further on:
If the build finishes without any errors it means that the components were added successfully to the project. You can now use the new drivers/components in your project.
Best regards,
