In the past one and a half years the MINIX team has been working on a port of MINIX 3 to the ARM platform. We now have a port of MINIX 3 to the popular BeagleBone Black.

In this talk I will look back at MINIX 3 on ARM and explain how it became what it is. I will show a few nice features it has, including some stolen from NetBSD and some related to automatic recovery from otherwise fatal system errors.

The goal of the talk is to shine an other light at embedded development and share our experience in this area.
