STM32 F4 401RE - interrupt EXTI same code: MBED stop, coide working!

mbed EXTI not working and then i try coide for compare and finding problem

test make blink led more fast when detect interrupt:

  • with mbed when interrupt is detect blink led is stop
  • with coide when interrupt is detect led blink fast with no problem

Note

  • SystemClock_Config(); not working with mbed

COIDE CODE:
