Zephyr mostly covers ARM boards with Cortex-M devices being their primary focus. However, Michael Gielda, VP of Business Development at Antmicro and Chair of the Zephyr Project Marketing Committee, explains that there are also different architectures, such as RISC-V and Xtensa. Renode similarly covers a range of architectures, again focusing predominantly on ARM. Both Zephyr and Renode support both wired and wireless communication interfaces. Since becoming a platinum member of Zephyr Project, Antmicro is working closer with the hub of vendors, interacting with them to improve support for their own platforms in Renode. Gielda discusses further in this video some of the platforms and devices Zephyr supports.
