============== NXP S32K118EVB ============== NXP S32K118EVB-Q064 is an evaluation board for the `NXP S32K118 MCU `_ based on an Arm Cortex-M0+ core. Features ======== - NXP FS32K118LAT0MLHT MCU - 48 MHz Clock (Max.) - 256 Kb Flash - 25 Kb SRAM - 2 Kb EEPROM - NXP UJA1169TK/F System Basis Chip - Connectivity: - OpenSDA UART (Console @ 115,200 baud) - CAN 2.0 (Transceiver part of UJA1169 SBC) - 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 PTB0 LPUART0_RX OpenSDA UART TX PTB1 LPUART0_TX =============== ==== ========== USB drivers for the PEmicro CDC Serial Port are available here: http://www.pemicro.com/opensda/ LEDs and Buttons ================ Leds ---- The S32K118EVB has one RGB LED: ======== ===== ======== RedLED PTD16 FTM0 CH1 GreenLED PTD15 FTM0 CH0 BlueLED PTE8 FTM0 CH6 ======== ===== ======== 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 s32k118evb.h): - GPIO_LED_R - GPIO_LED_G - GPIO_LED_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 S32K118EVB. 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 S32K118 in sleep mode ================ ======================= ===== ===== ==== Buttons ------- The S32K118EVB supports two buttons: === ==== SW2 PTD3 SW3 PTD5 === ==== 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. - Using Segger J-Link: Easy... but remember to use the SWD connector J14 near the touch electrodes and not the OpenSDA connector near the OpenSDA USB connector J7. Configurations ============== Each S32K118EVB configuration is maintained in a sub-directory and can be selected as follows:: tools/configure.sh s32k118evb: 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 LPUART1 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.
