Overview

The Icarus is a cost-effective cellular IoT board in Adafruit’s Feather/FeatherWing form factor. It is built around Nordic Semi’s nRF9160 modem and combines LTE-M, NB-IoT, GPS, accelerometer, USB, LiPo charger as well as an eSIM and a nano SIM connector.

The main uController is the Nordic Semiconductor nRF9160, with ARM Cortex-M33F CPU, ARMv8-M Security Extension and the following devices (provided directly by Nordic):

• ADC

• CLOCK

• FLASH

• GPIO

• I2C

• MPU

• NVIC

• PWM

• RTC

• Segger RTT (RTT Console)

• SPI

• UARTE

• WDT

• IDAU

Hardware

The detailed information about the on-board hardware can be found at the Icarus Product Website [2].

SIM Selection

The SIM choice (eSIM or nano-SIM) can be configured in Devicetree by adjusting the sim property in the sim_select node.

Charger Enable/Disable

Since hardware version 2.0 the charger can be disabled by adjusting the charger property of the charger_enable device tree node.

Security components

• Implementation Defined Attribution Unit (IDAU [1]). The IDAU is implemented with the System Protection Unit and is used to define secure and non-secure memory maps. By default, all of the memory space (Flash, SRAM, and peripheral address space) is defined to be secure accessible only.

• Secure boot.

Building Secure/Non-Secure Zephyr applications

The process requires the following steps:

1. Build the Secure Zephyr application using -DBOARD=actinius_icarus and CONFIG_TRUSTED_EXECUTION_SECURE=y in the application project configuration file.

2. Build the Non-Secure Zephyr application using -DBOARD=actinius_icarus/ns.

3. Merge the two binaries together.

If you are using Segger Embedded Studio v4.18 or later, the two binaries are built, merged, and burned automatically, unless you have disabled the feature.

When building a Secure/Non-Secure application, the Secure application will have to set the IDAU (SPU) configuration to allow Non-Secure access to all CPU resources utilized by the Non-Secure application firmware. SPU configuration shall take place before jumping to the Non-Secure application.

More information can be found in the Icarus “Get Started” Guide [3] or the Actinius Documentation Portal [4].
