The naked Attribute
Hi,
On Cortex-M based processors the “naked” attribute should not be used for ISRs; the processor itself does what is needed so that a normal function can be used as an interrupt handler. The prototype should be:void ''ISRname''_IRQHandler(void);
Regarding the ISR code, yes, your ISR should only use FromISR versions of the FreeRTOS functions.
