Resolved! Input capture interrupts not fired on STM32F401

Hello,I have configured a CUBE IDE project to match a Nucleo-F401RE board to measure the system clock pulses (at 84MHz) between to consecutive rising edges of an external signal applied to pin PA3 (which is Timer2 Channel4 input).The Input Capture in...
