USART3 communication is not working on Nucleo-H7A3 board

Split from this thread.
Hi there, switching to USART3 didn't work. I still don't see any messages in the serial console.

 

the second time I try to connect to the serial console gives this error.

Hello, 

Better to close this thread (by accepting the post that answered your original question, not this one) as you were using the wrong usart in this board and open a new thread mentioning the usage of usart 3. Please share your project there to help you efficiently.

You still haven't told us how you're actually making the connection from that UART to your terminal:

•  ST-Link VCP?
• External USB-to-UART adaptor?
• Other ... ?
•  

But, as @mƎALLEm said, it's now onto a different question; so time for a new thread - and be sure to include the details there:

Hello, I was using the ST-Link VCP. I have managed to get it working with SUART3 and Cool Term as my serial console.

 

But I cannot get the internal command shell console to connect more than once. Are there any known issues associated with this? And is there a way to reset the connection without physically disconnecting the cable?

 

Thank you for all of the help so far :D

What do you mean by that?

Is this in STM32CubeIDE ?

As said in the previous thread, that’s a new question and as suggested you need to share your project. Giving only the symptom could not help.
