Swedish Embedded Platform SDK Documentation

Swedish Embedded Platform SDK provides a full development environment for building connected IoT devices. It consists of:

  • Bootloader: MCUBoot

  • Kernel: powerful Zephyr RTOS kernel with support for over 400+ platforms.

  • Testing framework: CMock and Unity unit testing optimized for embedded firmware development.

  • Simulator: Integrated renode simulation for state of the art automated testing.


Testing and verification of physical embedded systems is often difficult due to poor reproducibility and lack of insight into the current state of the system, especially in multinode scenarios (sensors connected to a central and scenarios involving mesh networks).

Yet embedded devices often handle critical tasks and all functionality of the embedded device must therefore be thoroughly verified. The only way we can achieve this is through a properly setup continuous integration pipeline which runs scenarios against final production software. But traditionally this has been very hard because embedded software has to be cross compiled and needs real hardware to work.

Swedish Embedded SDK closes these gaps that were preventing you from achieving 100% verifiability of all levels of your software. With simulation we can capture all user requirements and run them continuously each time changes to the software are made. With powerful mock-based unit testing, we can test every little corner of your application logic and verify that the lowest level logic is correct.

When we combine high level scenario testing, mid-level integration testing and lowest level unit testing - we are able to achieve 100% robustness and stability of your embedded software.

Swedish Embedded Platform SDK combines all the tools you need to in order to achieve this effectively and without sacrificing portability of your code to future hardware.

You can build your production firmware, run all unit tests and then run the signed unmodified binaries, identical to the ones that you would normally flash onto your target hardware, on a virtual board or system of boards and verify user scenarios completely automatically, on CI server, each time anyone on your team submits a merge request.

One important aspect of our simulation approach is that it simulates not only CPUs but entire SoCs (including e.g. heterogeneous multicore SoCs and various peripherals) as well as the wired or wireless connections between them, which allows users to address complex scenarios and test real production software.

By using Zephyr RTOS kernel as our kernel of choice, we are able to meet all major challenges of continuously evolving IoT landscape and provide you with solutions that are truly future-proof.
