Status
======
2019-08-14: Configuration created but entirely untested. Support for the
S32K1XX family is incomplete. This configuration is intended, initially,
to support development of the architecture support. This is VERY much
a work in progress and you should not use this configuration unless you
are interested in assisting with the bring-up.
Serial Console
==============
By default, the serial console will be provided on the OpenSDA VCOM port:
OpenSDA UART TX PTB1(LPUART0_TX)
OpenSDA UART RX PTB0(LPUART0_RX)
LEDs and Buttons
================
LEDs
----
The S32K118EVB has one RGB LED:
RedLED PTD16 (FTM0CH1)
BlueLED PTE8 (FTM0CH6)
GreenLED PTD15 (FTM0 CH0)
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.
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:
======================+========+========+=========
RED GREEN BLUE
======================+========+========+=========
LED_STARTED OFF OFF OFF
LED_HEAPALLOCATE OFF OFF OFF
LED_IRQSENABLED OFF OFF OFF
LED_STACKCREATED OFF ON OFF
LED_INIRQ OFF N/C ON
LED_SIGNAL OFF N/C ON
LED_ASSERTION OFF N/C ON
LED_PANIC Flashing OFF N/C
======================+========+========+=========
Buttons
-------
The S32K118EVB supports two buttons:
SW2 PTD3
SW3 PTD5
Configurations
==============
Common Information
------------------
Each S32K118EVB configuration is maintained in a sub-directory and
can be selected as follow:
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
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 LPUART0 at
115,200 8N1. This corresponds to the OpenSDA VCOM port.
Configuration Sub-directories
-------------------------
nsh:
---
Configures the NuttShell (nsh) located at apps/examples/nsh. Support
for builtin applications is enabled, but in the base configuration no
builtin applications are selected.
