Nordic nRF9160 DK (nRF9160)

chip:nrf91, chip:nrf9160

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

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

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.

miniboot_s

This configuration is a simple bootloader that allows you to enter a TZ non-secure environment.

modem_ns

This configuration includes modem firmware and MUST BE run in non-secure environment. Booting into a non-secure environment can be done using the miniboot_s configuration.

To get this configuration working with miniboot bootloader follow these steps:

1. build firmware for miniboot and modem configuration:

   cmake -B build_boot -DBOARD_CONFIG=nrf9160-dk:miniboot_s -GNinja
   cmake -B build_modem -DBOARD_CONFIG=nrf9160-dk:modem_ns -GNinja
   cmake --build build_boot
   cmake --build build_modem
   

2. flash bootloader:

   nrfjprog --program build_boot/nuttx.hex --chiperase --verify
   

3. flash modem image:

   nrfjprog --program build_modem/nuttx.hex
   

4. reset chip:

   nrfjprog --reset
