|
||
|
|
|
||
|
|
By default, the serial console will be provided on the OpenSDA VCOM port:

The S32K146EVB has one RGB LED:
|
||
|
|
|
||
|
|
======== ===== ========
|
||
|
|
RedLED PTD15 FTM0 CH0
|
||
|
|
GreenLED PTD16 FTM0 CH1
|
||
|
|
BlueLED PTD0 FTM0 CH2
|
||
|
|
======== ===== ========
|
||
|
|
|
||
|
|
An output of '0' 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 s32k146evb.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 S32K146EVB. The following definitions describe how NuttX controls the LEDs:

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 S32K146EVB configuration is maintained in a sub-directory and can be selected as follows::
|
||
|
|
|
||
|
|
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. 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.
