LEDs and buttons

|
LEDs
|
|
----
|
|
|
|
There are four LED status indicators located on the EVK Board. The
|
|
functions of these LEDs include:
|
|
|
|
=== ============
|
|
Pin Description
|
|
=== ============
|
|
D3 Power Supply
|
|
D15 Reset LED
|
|
D16 OpenSDA
|
|
D18 User LED
|
|
=== ============
|
|
|
|
Only a single LED, D18, is under software control. It connects to
|
|
GPIO_AD_B0_09 which is shared with JTAG_TDI and ENET_RST
|
|
|
|
This LED is not used by the board port unless CONFIG_ARCH_LEDS is
|
|
defined. In that case, the usage by the board port is defined in
|
|
include/board.h and src/imxrt_autoleds.c. The LED is used to encode
|
|
OS-related events as follows:
|
|
|
|
================ ======================= =====
|
|
SYMBOL Meaning LED
|
|
================ ======================= =====
|
|
LED_STARTED NuttX has been started OFF
|
|
LED_HEAPALLOCATE Heap has been allocated OFF
|
|
LED_IRQSENABLED Interrupts enabled OFF
|
|
LED_STACKCREATED Idle stack created ON
|
|
LED_INIRQ In an interrupt N/C
|
|
LED_SIGNAL In a signal handler N/C
|
|
LED_ASSERTION An assertion failed N/C
|
|
LED_PANIC The system has crashed FLASH
|
|
================ ======================= =====
|
|
|
|
Thus if the LED is statically on, NuttX has successfully booted and is,
|
|
apparently, running normally. If the LED is flashing at approximately
|
|
2Hz, then a fatal error has been detected and the system has halted.
|
|
|
|
Buttons
|
|
-------
|
|
|
|
There are four user interface switches on the MIMXRT1050 EVK Board:
|
|
|
|
- SW1: Power Switch (slide switch)
|
|
- SW2: ON/OFF Button
|
|
- SW3: Reset button
|
|
- SW8: User button
|
|
|
|
Only the user button is available to the software. It is sensed on the
|
|
WAKEUP pin which will be pulled low when the button is pressed.

Configurations
|
|
==============
|
|
|
|
knsh
|
|
----
|
|
|
|
This is identical to the nsh configuration below except that NuttX
|
|
is built as a protected mode, monolithic module and the user applications
|
|
are built separately. For further information about compiling and
|
|
running this configuration please refer to imxrt1064-evk documentation.
|
|
|
|
netnsh
|
|
------
|
|
|
|
This configuration is similar to the nsh configuration except that is
|
|
has networking enabled, both IPv4 and IPv6. This NSH configuration is
|
|
focused on network-related testing.
|
|
|
|
nsh
|
|
---
|
|
|
|
Configures the NuttShell (nsh) located at examples/nsh. This NSH
|
|
configuration is focused on low level, command-line driver testing.
|
|
Built-in applications are supported, but none are enabled. This
|
|
configuration does not support a network.
