The meantioned feature is implemented using macro: CYGIMP_KERNEL_SCHED_SORTED_QUEUES. It is located under configuration/"eCos kernel"/"kernel schedulers"/"Number of priority levels"/"Dequeue oldest threads"

Subject: [ECOS] Re: priority tasks and mutex
This has come up before on the list. There is an option in ecos.ecc to make the list of waiting threads sorted into priority order. I don't remember its name and dont have access to the sources at the moment. Look back in the archive or maybe Nick can jump in with more info.

Hi,
I use a non reentrant library protected by a mutex and I would like to use the priority of the tasks to use it (one of my tasks needs to use the library before all the others). I made a test but it seems that it doesn't work. As anybody already done that ? Thank you. Raphaël SAGEM
