The Ethernet MAC and Switch implemented in the device supports GMII mode, but the design does not pin out 9 of the 24 GMII signals. This was done to reduce the total number of package terminals. Therefore, the device does not support GMII mode. MII mode is supported with the remaining GMII signals.
The AM437x Sitara Processors Technical Reference Manual and this document may reference internal signal names when discussing peripheral input and output signals because many of the package terminals can be multiplexed to one of several peripheral signals. For example, the terminal names for port 1 of the Ethernet MAC and switch have been changed from GMII to MII to indicate their Mode 0 function, but the internal signal is named GMII. However, documents that describe the Ethernet switch reference these signals by their internal signal name. For a cross-reference of internal signal names to terminal names, see Table 4-10.
Operation of the Ethernet MAC and switch in RGMII mode is not supported for OPP50.
