USART 2 Transmit not working

[Mani1]

Board : STM32F746G

I configure USART1 with same configuration. USART1 is working fine. I did same configuration for USART2 also, but USART2 not working. I don't know what's happening.

Thanks

Show RCC, GPIO and USART2 related initialization code.​

@Community member​  here i have attached my main.c file

What exactly is not working? It's not clear what you're trying to achieve. What is UART2 connected to? Did you scope the TX pin? is it pulled high by another component?

I am going to send "Hello!" via USART2 transmit. Same method i used for UASRT1 transmit, but there the hello printed in serial port. When i am using USART2 transmit, the "Hello!" is not print in serial port.

Thanks

And what do you mean with "serial port"? Are you scoping it? Or is it connected to FTDI -> USB? Hence my question "What is UART2 connected to?"...

I suppose that UART1 and UART2 are not connected to the same physical HW block

This is a chip, not a board. Do you mean the 32F746GDISCOVERY?

USART2 is not hooked up to the VCP.

YES
