Status
======
2019-08-20: Configuration created but entirely untested.
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)
USB drivers for the PEMIcro CDC Serial port are available here:
http://www.pemicro.com/opensda/
LEDs and Buttons
================
LEDs
----
The S32K148EVB has one RGB LED:
RedLED PTE21
GreenLED PTE22
BlueLED PTE23
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 s32k148evb. The following definitions describe how NuttX controls the
LEDs:
==========================================+========+========+=========
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 (no change)
LED_SIGNAL In a signal handler (no change)
LED_ASSERTION An assertion failed (no change)
LED_PANIC The system has crashed FLASH OFF OFF
LED_IDLE S32K148EVN in sleep mode (no change)
==========================================+========+========+=========
Buttons
-------
The S32K148EVB supports two buttons:
SW3 PTC12
SW4 PTC13
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 20-pin SWD J10
connector near the Ethernet connector and not J20 the 10-bit OpenSDA
connector closer to the OpenSDA USB connector J24.
Configurations
==============
Common Information
------------------
Each S32K148EVB configuration is maintained in a sub-directory and
can be selected as follow:
tools/configure.sh s32k148evb:<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.

* Description:
* Perform application specific initialization. This function is never

*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value cold be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
