Zephyr Developer Summit 2022

Although Zephyr's SDK now has support for macOS, there are some areas where the developer experience is not quite the same as on Linux. One of those areas is support for the native_posix build target. The native_posix build target allows us to run Zephyr as a native userspace process with a minimal amount of abstraction. It exercises the same code paths as on real target devices. It is used extensively for Zephyr's comprehensive integration and unit test suites as well as for the BLE simulator. Thus far, native_posix has mainly worked on Linux due to predominant use of ELF for all supported targets. However, there were some .. "speedbumps" when trying to add support for macOS which uses the Mach-O binary file format. In this talk, we detail what it takes to run Zephyr's native_posix target on macOS, challenges encountered along the way, as well as the remaining integration efforts.
