Is this on a board we might be familiar with?

Are you attempting this with break-points and a debug view of the peripheral parked on the registers you are using? Is so, try not doing that.

dear clive1.

I connected PA2 and PA3 of STM32f407 to a slave processor.

I want both processor to communicate using USART2.

I didn't use break-point and debug view.

I just tried to forward the received data from USART2 to USART1.

USART1 is connected to the PC terminal to check the received data.

Thank you.
