MPS2+ SSE-200 Devices Secure/Non-secure Example

PLEASE NOTE: These examples do not build when Keil Arm MPS2 SSE-200 BSP v2.0.0 or later is installed.

This example shows the same functionality described in the MPS2 device example. However, the implementation is different. The implementation is divided into secure and non-secure code.

The secure code performs the following functionality:

• Sets secure and non-secure system configuration.
• Gets and provides button states.
• Gets and provides touchscreen information.
• Sleep function.
• Switchs on/off user LEDs based on user button states.

The non-secure code performs the following functionality:

• Requests to the secure code:
  • Button states.
  • If the touchscreen is pressed in the central area.
  • Sleep for X amount of ms.
• Switches on/off the SCC LEDs.

To compile the example correctly it is necessary to first compile the secure code, and then the non-secure code.
Compiling the secure code generates the veneers object file required by the non-secure code to compile correctly.

See the ReadMe file provided with the example for further information.
