Overview

Octopus SoM is a System on Module (SoM) built around the nRF9160 SiP offering NB-IoT and LTE-M connectivity, GPS and accelerometer. It supports on board eSIM and external nano SIM connector. It’s purpose is to provide flexible hardware platform for IoT applications.

nRF9160 SiP contains ARM Cortex-M33 application processor and the following devices:

• ADC

• CLOCK

• FLASH

• GPIO

• I2C

• MPU

• NVIC

• PWM

• RTC

• Segger RTT (RTT Console)

• SPI

• UARTE

• WDT

• IDAU

More information about the board can be found at the Octopus SoM Product Page [1] and in the Octopus SoM Documentation [2].

Programming and Debugging

The octopus_som board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt
jlink	✅	✅ (default)	✅	✅	✅
nrfjprog	✅
nrfutil	✅ (default)

Norik Octopus SoM can be programmed and debugged using the exposed SWD pins.

Building an application

In most case you’ll need to use octopus_som/nrf9160/ns board target for building examples. Some examples don’t require non secure mode and can be built with octopus_som/nrf9160 board target.

Flashing

Refer to the instruction in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software.

Use the Blinky sample to test if Zephyr is running correctly on your board.

# From the root of the zephyr repository
west build -b octopus_som/nrf9160 samples/basic/blinky
west flash

Debugging

Refer to the instruction in the Nordic nRF5x Segger J-Link page for information on debugging.
