I can see in new UM is clearly mentioned that MAILBOX interrupt can't wakeup Core0 from Power-Down mode.
But I have a case when Core1 should wakeup Core0. What kind of other type of interrupts can be used for those purposes ?
In worst case I can use one GPIO pin what can be toggle other pin on Core0 what is part of GINT0 group.
But may be some easy alternatives exists.
