Hello,
spatial partitioning is not possible in ecos as ecos does not support
memory protection or similar stuff as far as I know. Also temporal
partitioning is not possible as any thread is able to prohibit
scheduling (Cyg_Scheduler::lock()) and, therefore, also is able to
monopolise the cpu.
Ciao, Fabian
