2.11.2.1 Control Card Ethernet Routing

The AM263Px SoC includes multiple Ethernet Ports and MDIO modules that can be routed to different locations based upon MUX/analog switch settings as well as which 0 Ω resistors are populated on the board. There are three single-pole single-throw (SPST) switches as well as IO control signals from the IO expander that determine the state of the MUX/analog switch routing.

Figure 3-20 Shows a high-level overview of the routing scheme for all ethernet ports and MDIO signals.

Table 3-16 details the various available configurations for ethernet and MDIO routing on the Control Card. The Default setting is configuration 1 which is also highlighted in green.

Note: Various configurations require soldering and removal of 0 Ω resistors.
