Hi STM Community,

I was trying to use USART2 on NUCLEO-G491RE board, but it is disabled from the start.

It is highlighted in Pink and I am not able to edit it.  Can you please tell me how to make it work ?

Thank you. Appreciate it.

Regards,

STMUSER

Hello,

Check if USART2 is already selected in the Bsp menu:

If it's the case you no more need to configure it in Connectivity menu.
Unless you need to customise the configuration. in that case disable it from the Bsp menu and USART2 will be available in the Connectivity menu.

    LPUART1 and UART2 uses the same RX/TX pins. You currently have LPUART1 enabled so that is why you can't use UART2. If you don't need the LPUART1 then disable it. Then you will be able to select UART2.
