Example application demonstrating S32K144 power modes
The purpose of the application is to show the user how to enter various power modes of the S32K144 SoC using the S32 SDK API.
The application displays on the host PC terminal a menu in which the user can select to enter:
The CPU can be woken up from sleep modes by pressing BTN1 (PTC13).
To 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 |
---|---|---|
LPUART1 TX (PTC7) | UART_TX - wired on the board | J11.26 - J20.2 |
LPUART1 RX (PTC6) | UART_RX - wired on the board | J11.25 - J20.5 |
BUTTON (PTC13) | BTN1 - wired on the board | SW4 - wired on the board |
After opening S32 Design Studio, go to File -> New S32DS Project From... and select power_mode_switch. 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(power_mode_switch). 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 |
---|---|
power_mode_switch Debug_RAM Jlink | Debug the RAM configuration using Segger Jlink debuggers |
power_mode_switch Debug_FLASH Jlink | Debug the FLASH configuration using Segger Jlink debuggers |
power_mode_switch Debug_RAM PEMicro | Debug the RAM configuration using PEMicro debuggers |
power_mode_switch 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.
For this example it is necessary to open a terminal emulator and configure it with:
