RT-Thread

RT-Thread 0.4.0 beta2 is the 2^nd version in RT-Thread 0.4.x series. This version is mainly for testing purpose, and is not recommended to be deployed in product. The RT-Thread 0.4.0 testing version is still released under the GPL v2 license. Welcome to test.

The original requirements for RT-Thread 0.4.0 are basically reached. Relative complete POSIX thread interface, load interface for dynamic library libdl and support for application modules are all provided. These new features enable the RT-Thread to be compatible with the POSIX standard at the first stage.
