OSEK Scheduling

Reading one thread about OSEK, reading one mail of Olaf, I have two questions to ask.

That's all, isn't it? But remember that for BCC2 the tasks are > non-preemptive and for ECC2 preemptions are allowed.

In BCC2, what happens if a ISR2 activates one task with more priority that the running one? (the same question for BCC1). I think that tasks can be preemptive, but they cannot go to the waiting state (because of a resource or event)

3) From this set of highest priorty tasks the scheduler chooses that one, > which is the oldest, i.e. that one with the lowest activation time.

One doubt I have from this point (and from the standard too) is what happens with the 'activation time' and the multiples activations of basic tasks. Let me explain with an example:

Imagine two tasks with the same priority, T_A and T_B. T_B is suspended, T_A is running (only one instance). T_B is activated by a ISR2, but keeps waiting in the ready state. T_A is activated again, so the second activation is stored. The first activation of T_A calls TerminateTask.

Which is the next task to be in running state? The second activation of T_A ? or T_B, as it has lower activation time?

Thanks in advance.
