Appearance

NXP S32K344EVB ​

NXP S32K3X4EVB-Q257 is an evaluation board for the NXP S32K344 MCU based on a Arm Cortex-M7 core (Lock-Step).

Features ​

NXP FS32K344

:   -   Lock-Step Configuration
    -   160 MHz Clock (Max.)
    -   4000 Kb Flash
    -   512 Kb RAM

  • NXP FS26 Safety System Basis Chip

Connectivity:

:   -   OpenSDA UART (Console @ 115,200 baud)
    -   2x Secure CAN transceivers
    -   I/O headers with GPIO, I2C, SPI, etc.

Serial Console ​

By default, the serial console will be provided on the OpenSDA VCOM port:

OpenSDA UART RX PTA15 LPUART6_RX OpenSDA UART TX PTA16 LPUART6_TX

USB drivers for the PEmicro CDC Serial Port are available here: http://www.pemicro.com/opensda/

LEDs and Buttons ​

Leds ​

The S32K344EVB has two RGB LEDs:

RedLED0 PTA29 EMIOS1 CH12 / EMIOS2 CH12 GreenLED0 PTA30 EMIOS1 CH13 / EMIOS2 CH13 BlueLED0 PTA31 EMIOS1 CH14 / FXIO D0

RedLED1 PTB18 EMIOS1 CH15 / EMIOS2 CH14 / FXIO D1 GreenLED1 PTB25 EMIOS1 CH21 / EMIOS2 CH21 / FXIO D6 BlueLED1 PTE12 EMIOS1 CH5 / FXIO D8

An output of '1' illuminates the LED.

If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in any way. The following definitions are used to access individual RGB components (see s32k344evb.h):

  • GPIO_LED0_R
  • GPIO_LED0_G
  • GPIO_LED0_B
  • GPIO_LED1_R
  • GPIO_LED1_G
  • GPIO_LED1_B

The RGB components could, alternatively, be controlled through PWM using the common RGB LED driver.

If CONFIG_ARCH_LEDs is defined, then NuttX will control the LEDs on board the S32K344EVB. The following definitions describe how NuttX controls the LEDs:

State Description RED GREEN BLUE

LED_STARTED NuttX has been started OFF OFF OFF LED_HEAPALLOCATE Heap has been allocated OFF OFF ON LED_IRQSENABLED Interrupts enabled OFF OFF ON LED_STACKCREATED LED_INIRQ LED_SIGNAL LED_ASSERTION Idle stack created In an interrupt In a signal handler An assertion failed OFF ON OFF LED_PANIC LED_IDLE The system has crashed S32K344 in sleep mode FLASH OFF OFF

Buttons ​

The S32K344EVB supports two buttons:

SW0 PTB26 EIRQ13 / WKPU41 SW1 PTB19 WKPU38

OpenSDA Notes ​

Configurations ​

Each S32K344EVB configuration is maintained in a sub-directory and can be selected as follows:

tools/configure.sh s32k344evb:<subdir>

Where <subdir> is one of the sub-directories listed in the next paragraph.

NOTES (common for all configurations):

This configuration uses the mconf-based configuration tool. To change this configuration using that tool, you should:

:   a.  Build and install the kconfig-mconf tool. See
        nuttx/README.txt. Also see additional README.txt files in
        the NuttX tools repository.
    b.  Execute \'make menuconfig\' in nuttx/ in order to start the
        reconfiguration process.
  1. Unless otherwise stated, the serial console used is LPUART6 at 115,200 8N1.

nsh ​

Configures the NuttShell (nsh) located at apps/examples/nsh. Support for builtin applications is enabled, but in the base configuration the only application selected is the "Hello, World!" example.
