Hi Finding the time difference between signals in microphones.

I am currently trying to use a stm32F767ZI to find the phase difference between a sound wave using three microphones. My plan is to use the three ADCs withDMA in simultanously mode to achieve high enough sampling time. My question is how to find the ...

I am using STM32F070F6P6 with my own board, and I have the following issue: When I start debug session in Keil run button is something like already pressed and when I stop the execution the PC is at address 0x1FFFCAC4. The program never enter main.

I use Cube MX to configure pins and peripherals.I think that is board issue but I can't find the reason.Thanks
