Nordic nRF5340 DK

The nRF5340-DK (PCA10092) is a development board based on the nRF5340 from Nordic.

Serial Console

Serial console for the application core:

Pin	Signal	Notes
P1.01	APP UART0 TX	virtual COM 0
P1.00	APP UART0 RX	virtual COM 0

Serial console for the network core:

Pin	Signal	Notes
P0.20	NET UART0 TX	virtual COM 1
P0.22	NET UART0 RX	virtual COM 1

LEDs and Buttons

LEDs

The PCA10092 has 4 user-controllable LEDs:

LED	MCU
LED1	P0.28
LED2	P0.29
LED3	P0.30
LED4	P0.31

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	P0.23
BUTTON2	P0.24
BUTTON3	P0.08
BUTTON4	P0.09

Configurations

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

tools/configure.sh nrf5340-dk:<subdir>

Where <subdir> is one of the following:

adc_cpuapp

This configuration shows the use of the ADC peripheral.

composite_cpuapp

NuttShell configuration for the application core with support for CDC/ACM with RNDIS composite driver.

nsh_cpuapp

Basic NuttShell configuration for the application core (console enabled in UART0, exposed via J-Link VCOM0, at 115200 bps).

nsh_cpunet

Basic NuttShell configuration for the network core (console enabled in UART0, exposed via J-Link VCOM1, at 115200 bps).

ostest_tickless_cpuapp

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

pwm_cpuapp

This configuration shows the use of the PWM peripheral.

qspi_cpuapp

NuttShell configuration with enabled support for on-board MX25R QSPI memory.

rpmsghci_bt_cpuapp

This configuration enables RPMSG Bluetooth HCI client on the application core and uses NuttX BLE stack for the host-layer

rpmsghci_nimble_cpuapp

This configuration enables RPMSG Bluetooth HCI client on the application core and uses nimBLE for the host-layer

rpmsghci_sdc_cpunet

This configuration enables RPMSG Bluetooth HCI server on the network core which can be accessed using RPMSG Bluetooth HCI client on the application core.

rptun_cpuapp

This configuration enables basic RPTUN support on the application core. The rptun command will be available from NSH.

rptun_cpunet

This configuration enables basic RPTUN support on the network core. The rptun command will be available from NSH.

sdc_cpunet

Enables Nordic’s SoftDevice controller on the network core and uses NuttX BLE stack for the host-layer. The btsak application is included as a builtin.

sdc_nimble_cpunet

Enables Nordic’s SoftDevice controller on the network core and uses nimBLE for the host-layer. The nimble test application can be used to enable a simple GATT server.

timer_cpuapp

This configuration shows the use of the TIMER peripheral.
