If this is 4.10 or older, the edf scheduler is not present. You will have periodic tasks scheduled by priority which is assumed to have had priority assigned by the rate monotonic priority assignment rule.

Have a look at the testuites/sptests/spedf* for example code.

I have a request :
Please tell me how can I add a periodic task which RTEMS run it periodically;
Can we use the operating systems utilities to do so?

for example I have a thread which it must run every 10 ms; How can tell to RTEMS to run it on EDF scheduler?

please help me to understand it;
