[ECOS] scheduling descrepency in eCos

Hi,

 We are facing a scheduling problem in eCos anonymous cvs
 (used for Motorola PowerPC860).
 We have a thread each at priority 14 & 25. Priority 14
 thread has a "gets()" in its code and hence always waits
 for some input from keyboard. So, ideally, this priority-14
 thread should get descheduled and the lower priority thread
 (ie, priority-25) should get CPU, but this is not happening.
 We found that Priority-25 is not getting CPU at all!
 What could be the reason?
 Kindly help.
 
 Regards
 Rajan
