This paper presents mainly the method of porting open source embedded RTOS uC/OS-II to DSP(TMS320LF2407A),which is a popular microcontroller.It solves the most important and difficult problems in the course of porting uC/OS-II,and the system after porting cut out.A porting has been implemented in on TMS320LF2407A experiment board and the system runs steadily and reliably under multitask environment.Many parameters have reached the demand of designing by testing.
