Flash partitioning for CSEc usage

Basic application that presents Flash partitioning for CSEc usage

Note
This example works only for CSEc enabled parts. SIM_SDID indicates whether CSEc is available on your device.
This example should only be ran from RAM.
After partitioning Flash for CSEc operation, using the JLink Flash configuration of any other project will not work anymore. Workaround:
  • Run csec_keyconfig example with ERASE_ALL_KEYS 0, using PEmicro debug configuration
  • Run csec_keyconfig example with ERASE_ALL_KEYS 1, using PEmicro debug configuration

Application description


The purpose of this demo application is to show the user how to enable the Cryptographic Services Engine module from the S32K118 MCU with the S32 SDK API.

The implementation demonstrates the following:

  • the enablement of the CSEc module, by showing how the Flash should be partitioned (using the Flash driver);

Prerequisites


The run the example you will need to have the following items:

  • 1 S32K118 board
  • 1 Power Adapter 12V (if the board cannot be powered from the USB port)
  • 1 Personal Computer
  • 1 Jlink Lite Debugger (optional, users can use Open SDA)

Boards supported


The following boards are supported by this application:

  • S32K118EVB-Q064
  • S32K118-MB

How to run


1. Importing the project into the workspace

After opening S32 Design Studio, go to File -> New S32DS Project From... and select csec_flash_part_s32k118. Then click on Finish.
The project should now be copied into you current workspace.

2. Generating the Processor Expert configuration

First go to Project Explorer View in S32 DS and select the current project(csec_flash_part_s32k118). Then go to Project and click on Generate Processor Expert Code
Wait for the code generation to be completed before continuing to the next step.

3. Building the project

Select the configuration to be built RAM (Debug_RAM) by left clicking on the downward arrow corresponding to the build button(. Wait for the build action to be completed before continuing to the next step.

4. Running the project

Go to Run and select Debug Configurations. There will be four debug configurations for this project:

Configuration Name Description
csec_flash_part_s32k118_debug_ram_jlink Debug the RAM configuration using Segger Jlink debuggers
csec_flash_part_s32k118_debug_ram_pemicro Debug the RAM configuration using PEMicro debuggers


Select the desired debug configuration and click on Launch. Now the perspective will change to the Debug Perspective.
Use the controls to control the program flow.
