Design
eCos was designed for devices with memory sizes in the range of a few tens or several hundred kilobytes,[3] or for applications with real-time requirements.
eCos runs on a wide variety of hardware platforms, including

.History
eCos was initially developed in 1997[4] by Cygnus Solutions which was later bought by Red Hat. In early 2002, Red Hat ceased development of eCos and laid off the staff of the project.[5] Many of the laid-off staff continued to work on eCos and some formed their own companies providing services for the software. In January 2004, at the request of the eCos developers, Red Hat agreed to transfer the eCos copyrights to the Free Software Foundation[6] in October 2005, a process finally completed in May 2008.
Non-free versions
The eCosPro real-time operating system is a commercial fork of eCos created by eCosCentric which incorporates proprietary software components. It is claimed as a "stable, fully tested, certified and supported version",[7] with additional features that are not released as free software. On Pi Day 2017, eCosCentric announced[8] they had ported eCosPro to all of the Raspberry Pi models, with demonstrations at the Embedded World trade fair in Nuremberg (Germany) and releases free for non-commercial uses to follow.
