Hi all


I'd like to use UART2 to receive data, but It seemed to be failed, only could transmitted data.

I used the same codes in UART1, everything is fine,

So I think HW and SW parts are fine except UART2.


I had not connect SB62 & SB63  to enable PA3 & PA2, and used the CN3 of the st-link part for my project.

May I miss something? Or I should connect SB62 & SB63 to use PA3 & PA2 pins?


If anyone could tell me how to fix it?

Thank you in advance.
