Hi List,
I wrote an interrupt handler a few times ago. This handler is an idle
task which use the function *rt_intr_wait(&intr_desc, TM_INFINITE).
*
The programm works fine, but I would like to know if I have to save the
fpu context when an interrupt occurs and if there's a function to do it?
Best regards,
Cédric

No, you do not have to care about that.
