Summary
🤩
Rockstar🎓
Top SchoolEivind Jølsgard is an R&D engineer based in Trondheim with four years' experience building cellular and embedded systems at Nordic Semiconductor after earning an M.Sc. in Cybernetics and Robotics from NTNU. He contributes to high-profile open-source projects like the Zephyr RTOS and the nRF Connect SDK, where his work improved flash and modem support, CRC handling, and UARTE async/interrupt coexistence to boost reliability and throughput. Comfortable across low-level firmware, modem AT stacks, and hardware bring-up, he focuses on pragmatic changes that make constrained IoT devices more robust in the real world. Outside work he leads a folk swing dance group and pursues climbing, paddling, and mountain hiking—activities that reflect his collaborative leadership and appetite for hands-on problem solving.

Contributions summary:Eivind primarily focuses on modifying the Zephyr RTOS codebase. Their contributions include implementing an option to disable CRC for FCB entries, improving write throughput. They added board support for the nRF9161DK, and made subsequent changes, including disabling external flash by default, and adding support for external flash on the 0.7.0 version. Other changes were related to changing order of buttons and switches and ensuring the async and interrupt API's could coexist in the UARTE driver.
