External interruption flag not detected - Nucleo64 -STM32F091RC

[AAmor.2]

Hello,

I am working on Flighing sensors VL53L3 and I would like to run them in interrupt mode.

But my board (Nucleo-64 STM32F091RC) doesn't detect any flag in the falling edge trigger.

I have already run this interrupt mode on another board and this worked well.

I also tried to set the interruption pin on the user Button and that's work perfectly!

Moreover, I checked with a logic analyzer if the sensor set down rightly the interruption wire and it is the case.

I saw on different forums that it's could be a memory issue or a clock one but I have any ideas to debug my issue...

I will attach my project folder (I am working with AC6 tools for STM32).

Thanks for future help

Read out and check GPIO registers for given pin, if it's set to Input. Read out and check relevant SYSCFG_EXTICRx register to see if the given pin number's field selects the given pin's port. Read out and check the EXTI registers, whether given EXTI number edge is enabled and interrupt is enabled; you should also see the given pending bit go high if the pin is activated. Then follow the interrupt signal's logical path as outlined here.
