2019-08-148 Configuration created but entirely untested. This
|
|
configuration is intended, initially, to verify s32k14x architecture
|
|
support. The configuration builds and linkes without error but has
|
|
not yet been tested. 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 PTC7 (LPUART1_TX)
|
|
OpenSDA UART RX PTC6 (LPUART1_RX)
|
|
|
|
LEDs and Buttons
|
|
================
|
|
|
|
LEDs
|
|
----
|
|
The S32K146EVB has one RGB LED:
|
|
|
|
RedLED PTD15 (FTM0 CH0)
|
|
GreenLED PTD16 (FTM0 CH1)
|
|
BlueLED PTD0 (FTM0 CH2)
|
|
|
|
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 s32k146evb. The following definitions describe how NuttX controls the
|
|
LEDs:
|
|
|
|

|

Buttons
|
|
-------
|
|
The S32K146EVB supports two buttons:
|
|
|
|
SW2 PTC12
|
|
SW3 PTC13

Common Information
|
|
------------------
|
|
Each S32K146EVB configuration is maintained in a sub-directory and
|
|
can be selected as follow:
|
|
|
|
tools/configure.sh s32k146evb:<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 LPUART1 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.
