Example application that will show the usage of the Watchdog
The purpose of this driver application is to show the user how to use the WDOG from the S32K144 using the S32 SDK API.
The examples uses the SysTick timer from the ARM core to refresh the WDOG counter for 8 times. After this the Watchdog counter will expire and the CPU will be reset. If the FLASH configuration will be used, then the code will use the Reset Control Module to detect if the reset was caused by the Watchdog and will stop the execution of the program.
The run the example you will need to have the following items:
The following boards are supported by this application:
The following connections must be done to for this example application to work:
PIN FUNCTION | S32K144EVB-Q100 | S32K144-MB |
---|---|---|
RED_LED (PTD15) | RGB_RED - wired on the board | J12.17 - J11.31 |
GREEN_LED (PTD16) | RGB_GREEN - wired on the board | J12.16 - J11.30 |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select wdog_interrupt. Then click on Finish.
The project should now be copied into you current workspace.
First go to Project Explorer View in S32 DS and select the current project(wdog_interrupt). 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.
Select the configuration to be built FLASH (Debug_FLASH) or RAM (Debug_RAM) by left clicking on the downward arrow corresponding to the build button(. Wait for the bulid action to be completed before continuing to the next step.
Go to Run and select Debug Configurations. There will be four debug configurations for this project:
Configuration Name | Description |
---|---|
wdog_interrupt Debug_RAM Jlink | Debug the RAM configuration using Segger Jlink debuggers |
wdog_interrupt Debug_FLASH Jlink | Debug the FLASH configuration using Segger Jlink debuggers |
wdog_interrupt Debug_RAM PEMicro | Debug the RAM configuration using PEMicro debuggers |
wdog_interrupt Debug_FLASH PEMicro | Debug the FLASH 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.
