NXP S32K118EVB
==============
NXP S32K118EVB-Q064 is an evaluation board for the `NXP S32K118 MCU <https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-general-purpose-mcus/s32k1-microcontrollers-for-general-purpose:S32K1>`_ 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:<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:
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.
