STM32L152VE: Trouble using interrupts from ports F and G

[ADeva.1]

I am using STM32L152VE microcontroller and I am trying to blink an LED using external interrupts. The interrupt works fine in all the ports except port F and G does anybody have any idea as to why this might happen?

Thanks in advance

Check the clocks, check.the plumbing diagram​

In debug mode I reviewed and the clock is enabled and the EXTI lines are configured and everything seems good. I am using one of the example program and it works perfectly for all the other ports but not F and G.
