============== 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: Where 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: 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. 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.
