Nope, never did. We build 2 OS(s): the first was based on linux with a rtos package (2013-14?). That was scrapped and a new fully custom hardware package was built with a fully custom OS (built by a team that never had done this) and was built for a low power arm processor. We were plagued by huge issues most of the time due to that OS being nearly impossible to debug or work with. Also doing that prevented any third-party from building anything because there wasn't a SDK or even a platform to build on.
