Not everything is written in C. On a project I recently worked on we opted for Linux on the embedded platform to support some 3rd party tools and allow ourselves to work in easier-to-prototype languages.

Additionally, the management of the device is now “just Linux”, which is fairly Elmore well known.

In retroperspective, I don’t know if I would do it in the future. There are definite advantage in using Linux, but there is also a lot of work involved in understanding Linux and keeping track of the platform. That is true for a simpler OS, but I feel it might be more manageable.
