I am working with the SoC FPGA Smartfusion2 M2S010-MKR-KIT. It is intended to exchange some data between the SoC and the PC. For that reason, I aim to use Ethernet.
As far as I understood, in order to establish a proper communication using Ethernet, an interface TBI or GMII or MII should be programmed in the fabric in as means to communicate between the MAC and the Ethernet PHY.
Based on what should we decide which interface to use: TBI, GMII or MII?
