STR710 interrupt and freeRTOS

Posted by Frank Andersen on September 21, 2007

Does the port for the STR71x support nested interrupts?

Meaing while executing eg. the TimerTickInterrupt, does it then accept interrupts of a higher priority?

Or is the higher priority interrupt blocked until the end of TimerTickInterrupt?

Best regards,

Frank Andersen

Here is an FAQ on this http://www.freertos.org/FAQISR.html#Nest

Consider using the FIQ before changing to use nested interrupts.

Hi Dave,

Unfortuneatly the STR710 is not very flexible with use of FIQ, only the watchdog and timer0 can be asigned to FIQ.

When will the configKERNEL_INTERRUPT_PRIORITY be implemented in the ARM7 ports?

Best regards,

Frank Andersen
