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	Idle stack created	OFF	ON	OFF
LED_INIRQ	In an interrupt
LED_SIGNAL	In a signal handler
LED_ASSERTION	An assertion failed
LED_PANIC	The system has crashed	FLASH	OFF	OFF
LED_IDLE	S32K344 in sleep mode

Buttons

The S32K344EVB supports two buttons:

SW0	PTB26	EIRQ13 / WKPU41
SW1	PTB19	WKPU38

OpenSDA Notes

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

• The drag’n’drog interface expects files in .srec format.

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):

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

   1. Build and install the kconfig-mconf tool. See nuttx/README.txt. Also see additional README.txt files in the NuttX tools repository.

   2. Execute ‘make menuconfig’ in nuttx/ in order to start the reconfiguration process.

2. 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.
