The manditory question here is: Are you sure you need an RTOS?


Please provide more information, e.g.:


This is a networked device.


I am using Embedded Databases.


I am controlling USB devices.


I need a file system.


I need X-windows support.


I am running multiple applications concurrently.


What do you need a full OS for?

I can't understand it either. The RTOS takes up large amounts of resources in space and time. A large number of times I see an RTOS used (eve a free one) it adds a vast amount of complexity, development time and often real expense in hardware and production costs.

Even though I sell an RTOS I usually caution against it's use unless there is a real need. Usually because the project will require multiple process's and requires thing like your list above: file system, network, USB database etc.
