Project Description

RTEMS is a real-time embedded operating system. Currently, a minimum RTEMS application will automatically include part of reentrant C library, shutdown code and filesystem infrastructure. These codes are hard to remove because they are tightly coupled with other kernel components. TinyRTEMS would focus on breaking linkages between components so they can be configured by the user. The goal is to be able to provide the user with a full featured RTEMS library and defer as much configuration as possible to application configuration and link time.

In this project, I will introduce several changes to RTEMS source code and its build system to make it more 'tiny', configurable and scalable. These include: an alternative lightweight standard POSIX file I/O interface; more configuration options and simplified configuration steps; modifications to the source code to take more features out at the user's discretion. And finally I will give a well-written User's Manual and a Design & Implementation description in detail.

The original proposal is available here:




Currently I am working on the design description, specifically on the POSIX file I/O routines.
