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:

|
|
The S32K118EVB supports two buttons:

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.
|

|
-------------------------
|
|
|
|
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.
