Instability in Ethernet connections with RTL8201FI #11302
-
Hello everyone,
I'm changing my hardware project to use the RTL8201 instead of the LAN8720A.
The problem is that I can't get a stable connection with this new IC. When I start the communication, I can't always connect, and when I remove the cable and reconnect it, I don't receive the reconnection event. Can anyone help me with this???
I created a firmware as a proof of concept, below, along with the execution logs.
I'm using version 2.0.9 of the core, since this is the version that the rest of the project is based on, and a change would be extremely honorable.
