FreeRTOS

Free RTOS kernel - preemptive, cooperative and hybrid configuration options.
The SafeRTOS derivative product provides a high level of confidence in the code integrity.
Designed to be small, simple and easy to use.
Very portable code structure predominantly written in C.
Supports both tasks and co-routines.（同时支持任务和协程）
Powerful execution trace functionality.（强大的运行和跟踪功能）
Stack overflow detection options.（堆栈溢出检测）
No software restriction on the number of tasks that can be created.
No software restriction on the number of priorities that can be used.
No restrictions imposed on priority assignment - more than one task can be assigned the same priority.
Queues, binary semaphores, counting semaphores, recursive semaphores and mutexes for communication and synchronisation between tasks, or between tasks and interrupts.
Mutexes with priority inheritance.
Free development tools (Cortex-M3, ARM7, MSP430, H8/S, AMD, AVR, x86 and 8051 ports).
Free embedded software source code.
Royalty free.
Cross development from a standard Windows host.
Pre-configured demo applications for selected single board computers allowing 'out of the box' operation and fast learning curve.
Compile time configuration allows a ROM footprint print as low as 4.3Kbytes on an ARM7 (Thumb mode) using GCC (third party figures, requires specific GCC command line options).

看完这些介绍，让我对这个FreeRTOS有了一定的兴趣，但是对它的稳定性，现在有点质疑，不知道其稳定性能达到一个什么程度？能像uC-OS-II那样稳定可靠吗？它的出现是否要抢占uC-OS-II的市场呢？这无疑给uC-OS-II一个比较沉重的打击，我了解的和知道的实时操作系统都是收费的，没有免费的。它的免费，是否会像linux一样有前景呢？呵呵～期待它的强大。去下载一个源码，学习一下～
