What need to do to declare EXT interrupt STM32F722 family

[ShmuelG]

I am sorry, I just did not pay attention. SORRY!!!!

But your correction didn't help. I receive exactly HardFault exception, which received before:
- HardFault_Handler() at vectors.S:463 0x208994
- <signal handler called>() at 0xffffffe1
- __set_PSP() at cmsis_gcc.h:279 0x209dc0
- _port_irq_epilogue() at chcore_v7m.c:160 0x209dc0
- 0x89a

What do you think, what is the problem now?
