I'm teaching a basic course in embedded systems. We used FreeRTOS to review the OS concepts. However I was not able to find a port for Keil and IAR compilers for the Freedom platform. Then I port it. Porting FreeRTOS is easy, but not as easier to get it from someone else :-)
Find it attached.It toggles the LED and prints some message through serial terminal.
Note: if you want to add the useful Freescale-clone-project utilities (make_new_project.exe for IAR or make_new_project-sc_Keil.exe for Keil inside its respective build folder), they don't copy the FreeRTOS folder (and all its content). You have to copy it manually (inside the src\projects\platinum folder).
