S32K148EVB-Q176

Overview

NXP S32K148-Q176 [8] is a low-cost evaluation and development board for general-purpose industrial and automotive applications. The S32K148-Q176 is based on the 32-bit Arm Cortex-M4F NXP S32K148 [9] microcontroller. The onboard OpenSDA serial and debug adapter, running a mass storage device (MSD) bootloader and a collection of OpenSDA Applications, offers options for serial communication, flash programming, and run-control debugging. It is a bridge between a USB host and the embedded target processor.

Note

Before using the Ethernet interface, please take note of the following:

  • For boards with the part number LSF24D at U16, R553 needs to be depopulated.

Connections and IOs

This board has 5 GPIO ports named from gpioa to gpioe.

Pin control can be further configured from your application overlay by adding children nodes with the desired pinmux configuration to the singleton node pinctrl. Supported properties are described in dts/bindings/pinctrl/nxp,port-pinctrl.yaml.

LEDs

The NXP S32K148-Q176 board has one user RGB LED that can be used either as a GPIO LED or as a PWM LED.

Programming and Debugging

The s32k148_evb board supports the runners and associated west commands listed below.

flash debug

Applications for the s32k148_evb board can be built in the usual way as documented in Building an Application.

This board configuration supports SEGGER J-Link [10] West runner for flashing and debugging applications. Follow the steps described in J-Link Debug Host Tools, to setup the flash and debug host tools for this runner.

Flashing

Run the west flash command to flash the application using SEGGER J-Link.

Debugging

Run the west debug command to start a GDB session using SEGGER J-Link.

Configuring a Console

We will use OpenSDA as a USB-to-serial adapter for the serial console.

Use the following settings with your serial terminal of choice (minicom, putty, etc.):

  • Speed: 115200

  • Data: 8 bits

  • Parity: None

  • Stop bits: 1
