There are 2 functions: os_evt_set(..); isr_evt_set(..); i know isr_evt_set(..) can't be called from FIQ intterupt function, but can i use os_evt_set(..) under FIQ?
void FIQ_Handler(void) __fiq { //.... os_evt_set(..); }
Sorry it is not allow to call OS function for FIQ functions. You should implement this as a IRQ function instead.
