Use le_thread_SetPriority to set thread's priority

Legato Application Framework
1

Hi,I have a problem about Thread.I want to create a thread in my legato application。when I use legato interface <le_thread_SetPriority()> to set thread’s priority,I set priority to 0-3, it ran successfully, but when I set priority to 4-35, it ran errors.
run log:
Jan 6 01:46:50 | task_simple[23605]/task_simple_exe T=main | _main.c main() 60 | == Starting Event Processing Loop == Jan 6 01:46:50 | task_simple[23605]/framework T=main | LE_FILENAME SetSchedPolicyAttr() 497 | Set scheduling policy to SCHED_OTHER for thread '1'.

Priority 0-3: Set scheduling policy to SCHED_OTHER for thread ‘1’.
Priority 4-35:Set scheduling policy to SCHED_RR for thread ‘2’.

Insufficient permissions to create thread ‘2’ with its current attributes.`

How can I get permission?
