The EVM includes XDS110 class embedded JTAG emulation through the micro B connector J28. The EVM also has an optional TI20 pin (J25) connector to support external JTAG emulation. When an external emulator is connected, internal emulation circuitry is disabled.
The design includes the footprint for a MIPI60 (J33) connector with connections for JTAG and trace capabilities. The trace pins are pinmuxed with GPMC signals which, by default, are connected to HSE connector on the processor board. Resistor networks are used to steer these signals to either the HSE connector or to the MIPI60 connector. The MIPI60 is not installed as delivered.
Resistor options are provided to connect these signals to the HSE or Trace connector as mentioned in the Table 3-13.
The pinout of TI20 pin connector and MIPI60 pin connector are given in Table 3-13 and Table 3-15, respectively.
