Re: Timers in a task context

It looks like a difference in operation to say, for example ThreadX, who's tx_thread_identify() function is documented similarly "If this service is called from an ISR the return value represents the thread running prior to the executing interrupt handler", however in operation in ThreadX there is

Re: Timers in a task context

Hi, I think I've managed to narrow it down,. rtems_task_self() is documented as "If called from an interrupt service routine, this directive will return the Id of the interrupted task.",.. however if you run a timer server and your timer is initiated using rtems_timer_server_fire_after(), then
