nucleo-f410RB uart problem

[uveuvenouve]

I have nucleo-f410rb on hand
i tried to connect all three uart pin on the board (uart 1,2,6)
none of them work

and i found if i use keil to code the board, the uart2 message could come out from arduino board uart pin

but if i used STM32CubeIDE , it can't even come out from arduino board uart pin

i searched for this problem.

some said it is the problem of the division of uart clock(since i can see the message when keil is used, i don't think it is related)

 

what is the problem?

seems my uart to usb device somehow not match stm32
i changed to a device use ch340 and now work
