You need to know:

- the PC's ethernet interface's name, then select that

- your STM32's IP address, simply watch the stream, or filter for that IP address

Wireshark just sees Ethernet (or whatever) - it neither knows nor cares anything about STM32.

So there is nothing specific to STM32.

So just follow the standard Wireshark documentation:

Wireshark User Guide: https://www.wireshark.org/docs/wsug_html/ 

https://www.wireshark.org/docs/

https://www.wireshark.org/learn

https://ask.wireshark.org/questions/

This does, of course, require that you have a basic understanding of networking ...

Try a general internet search for "Wireshark beginners"...

What do you mean by "CPU" here ?

A diagram would help.

Maybe also some good, clear photographs of your setup
