The common processor card includes XDS110 class on-card emulation through the micro B connector J23. It also has an optional TI20 pin (J13) connector to support external emulation. When an external emulator is connected, internal emulation circuitry is disabled. The design includes the footprint for a MIPI60pn (J32) connector with connections for JTAG and trace capabilities. The trace pins are pinmuxed with ICSSG2 RGMII signals which, by default, are connected to Ethernet PHYs on the processor board. Resistor networks are used to steer these signals to either the Ethernet PHYs or to the MIPI60 connector. The MIPI60 is not installed as delivered.
ICSSG2 Ethernet signals from the SoC are multiplexed with JTAG trace signals. Resistor options are provided to connect these signals to the Ethernet PHYs or Trace connector, as shown in Table 3-15.
