Hi, all, I am looking for a free and open embeded RTOS, and found some more. FreeRTOS is good, but my boss let me compare another. There is an embeded rtos kernerl named CooCox OS,  the site is www.coocox.org, however, the os was short of  successful  embeded applications, can you give me some suggestion? Thanks!

Grasshoppers, Why don’t you use FreeRTOS?  Looks like CooCox is specifically for ARM Cortex-M3 uC’s – did you give that a try?  Have you tried FreeRTOS? Best suggestion I can give you is to use FreeRTOS. Regards, John W.
