Hello, I have three STM32F469I-DISCO boards that I need to be fully synchronized. As I searched, the best way to do this is by making them all operate with the same clock. How can I do this? Please help.

I read that this is possible by using an external clock or making two of them connected to the third board's clock. However, I do not know how to implement this. Please assist.
