With more than 100 real-time operating systems (RTOSs) available globally, according to Wikipedia, why should another like Zephyr, at the end of the alphabet, be of interest—and why does its latest version merit attention? You might also ask, “Why should I be interested in Zephyr 3.4?”
Let’s start with roots. The Linux Foundation supports collaboration on open-source software, hardware, and standards. Zephyr is the Linux Foundation’s RTOS, running not only on small embedded processors, but also on larger processors. It now boasts an extensive set of libraries and capabilities and runs on 450+ development boards from most major manufacturers, though that’s not as many as some more established RTOSs.
