Ping does not work in test by connecting embedded board and PC with LAN cable
I am developing an embedded board and changing from a Phy that works at 100 Mbps to a Phy chip that works at 1 Gbps, and I am testing it by connecting the board and PC with a LAN cable.
I imported the code that worked with Uip at 100 Mbps before and tested it.When checking the network adapter on the PC control panel, it is confirmed that it is connected at 10Mbps. However, when I ping it, it doesn't work. Probably, Auto-Negonation is not working, so it is expected to connect at 10Mbps instead of 1Gbps, and if you read the Phy status value through mdio interface, Auto-Negonation is not working.If you forcibly set 1Gbps in the Phy chip setting, it is confirmed that it is changed to 1Gbps when checking the network adapter in the PC control panel, but it does not work when pinging in an abnormal state. When checking the network status with "arp -a", the IP address registration is also not confirmed.
