Nordic nRF9160 DK (nRF9160)

The nRF9160-DK (PCA10090) is a development board based on the nRF9160 and nRF52840 from Nordic.

Serial Console

Serial console for the application core:

Pin	Signal	Notes
P0.28	APP UART0 TX	virtual COM 0
P0.29	APP UART0 RX	virtual COM 0

Serial console for the MCUBOOT (secure domain):

Pin	Signal	Notes
P0.00	APP UART1 TX	virtual COM 2
P0.01	APP UART1 RX	virtual COM 2

LEDs and Buttons

LEDs

The PCA10090 has 4 user-controllable LEDs:

LED	MCU
LED1	P0.02
LED2	P0.03
LED3	P0.04
LED4	P0.05

A low output illuminates the LED.

CONFIG_ARCH_LEDS

If CONFIG_ARCH_LEDS is not defined, then the LEDs are completely under control of the application. The following interfaces are then available for application control of the LEDs:

uint32_t board_userled_initialize(void);
void board_userled(int led, bool ledon);
void board_userled_all(uint32_t ledset);

Pushbuttons

BUTTON	MCU
BUTTON1	P0.06
BUTTON2	P0.07

Configurations

Each configuration is maintained in a sub-directory and can be selected as follow:

tools/configure.sh nrf9160-dk:<subdir>

Where <subdir> is one of the following:

nsh

Basic NuttShell configuration (console enabled in UART0, exposed via J-Link VCOM connection, at 115200 bps).

ostest_tickless

This is a NSH configuration that includes apps/testing/ostest as a builtin and enable support for the tick-less OS.
