Frosted Embedded POSIX OS
A free POSIX OS for Cortex-M embedded systems
FROSTED is an acronym that means "FRee Operating System for Tiny Embedded Devices". The goal of this project is to provide a free kernel for embedded systems, which exposes a POSIX-compliant system call API. In this talk I aim to explain why we started this project, the approach we took to separate the kernel and user-space on Cortex-M CPU's without MMU, and showcase the latest improvements on networking and supported applications.
