Editing a device configuration

To let you edit a device configuration, S32 Design Studio provides perspectives named Pins, Clocks, Peripherals, IVT (Image Vector Table), DCD (Device Configuration Data), and DDR Configuration. The settings that you edit and save in these perspectives are automatically stored in the configuration file of the currently used project.

To edit a device configuration in a perspective, do any of the following:

Double-click the MEX file in the Project Explorer. By default, you will get to the Pins tool.
Select the project in the Project Explorer and click the (Open S32 Configuration) button on the toolbar. Click to open the required perspective.
Right-click the project in the Project Explorer pane. On the drop-down context menu, click S32 Configuration Tool and the required option.

The use of settings in the perspectives is beyond the scope of this document. You can read more about the subject in the S32 Configuration Tool Getting Started guide. To open this guide, click Help > Help Contents on the menu.

While configuring your processor, you can switch between the perspectives using the (Open S32 Configuration) toolbar button.

To save the changes to the project, use the Update Project toolbar button. A click on this button either saves the latest device configuration silently, or opens the Update Project Files dialog box.

When saving the changes for the first time, clickUpdate Project > Open Update Project Dialog.

In the Update Project Files dialog box, select the device configuration files to be created in the project and updated with the latest pin, clock, and peripheral settings:

When you click OK, the project will be updated as follows:

If a file is labeled “create”, it will be created in the project's board folder.
If a file is labeled “no change”, there are no updates to be saved to this file.
If a file is labeled “change”, the existing file will be updated in the board folder. Click the “change” label to compare the file before and after update.
If a file is not selected, it will be skipped from update, or not created.

You can configure the Update Project button to always open the Update Project Files dialog box. To do it, select the Always show details before Update Project option in the Update Project Files dialog box, then click OK.
