ECos

The Embedded Configurable Operating System (eCos) is a free and open-sourcereal-time operating system intended for embedded systems and applications which need only one process with multiple threads. It is designed to be customizable to precise application requirements of run-time performance and hardware needs. It is implemented in the programming languagesC and C++ and has compatibility layers and application programming interfaces for Portable Operating System Interface (POSIX) and The Real-time Operating system Nucleus (TRON) variant μITRON. eCos is supported by popular SSL/TLS libraries such as wolfSSL, thus meeting all standards for embedded security.
