Software 

NORA-B1 series modules are used as open CPU modules in which applications developed with the 
Nordic Semiconductor nRF Connect SDK  can be run.  The most recent application development 
guidelines are found at the nRF Connect SDK documentation for application development [17] and 
working with the nRF53 [18]. These sections provide details about Zephyr, MCUboot, and the nRF53 
in NORA-B1. 

2.1

 

Nordic Semiconductor nRF Connect SDK  

With a broad selection of drivers and libraries, the Nordic Semiconductor nRF Connect SDK provides 
a rich development environment for various devices and applications. The software development kit 
(SDK)  is delivered through the nRF Connect for Desktop application provided by Nordic 
Semiconductor.  

nRF Connect  SDK  includes the SEGGER Embedded Studio IDE, Zephyr Project RTOS, MCUboot 
secure bootloader,  and nrfxdrv libraries for the peripherals provided within the nRF5340 chip.  The 
SDK can be downloaded from Nordic Semiconductor’s website [15] 

After installing the main program, select the following software modules for installation: 

 

Bluetooth Low Energy – general tool for development and testing with Bluetooth Low Energy 

 

Toolchain Manager – install and manage tools to develop with the nRF Connect SDK 

Other software modules in nRF Connect for Desktop can be useful but are not required for application 
development. 

2.1.1

 

Toolchain Manager 

Application development is done using the suite of tools installed by the Toolchain Manager. 

1.

 

Open the Toolchain Manager. Several versions of the nRF Connect SDK are offered. If this is a 
new install, select the latest one for installation. 

2.

 

Select an installation folder. If the default is not used, ensure that no spaces are included in the 
given folder path. 

3.

 

The installation can take several minutes to download and several more to install the SEGGER 
Embedded Studio IDE, git tools, bash shell, a fork of the Zephyr RTOS source code, Nordic’s 
custom source code (nrfxdrv), and MCUboot. While waiting, check the information at the “First 
steps to build” button. The displayed information is customized to the installation folder selected 
above. If the EVK-NORA-B1 development board is used for development, the examples given for 
the nRF5340 DK (pca_10095) can be used without modification. 

4.

 

Once the install is complete, open the IDE. 

5.

 

From this point, follow the “First steps to build” instructions presented by the Toolchain Manager 
and nRF Connect SDK online documentation. 

 

Nordic Semiconductor provides a free, unlimited commercial license for SEGGER Embedded 
Studio.  

2.1.2

 

Documentation – nRF Connect SDK 

Full documentation for the nRF Connect SDK is continually updated on the dedicated nRF Connect 
SDK documentation website [16].
