Hello again,
is there a way to send something to a queue from vPreemptiveTick ISR?
On Atmels AT91SAM7 the PIT Interrupt Vector is shared with other system components (e.g.:debug-uart) so i have to decide in this interrupt if it is an PIT or the DBGU-UART which caused the interrupt.
I want to send something to a queue from ISR, if the UART caused this Interrupt.
But for now the System crashes, if i try "sendtoqueue from isr". I think i have to deal with the "naked" attribute somehow, but could you please help me how to achieve this?

Thank you!

You can set configUSE_TICK_HOOK to 1 in FreeRTOSConfig.h. Then write a function

void vApplicationTickHook( void )
{
/*QueueSendFromISR() can go here. */
}
