K2G General Purpose Evaluation Module (EVMK2G)
3.4 JTAG Emulation Overview
The EVM supports two types of Emulation: On-Board-XDS200 emulator and 60-pin MIPI Header.
When external emulator is not connected to MIPI 60-pin connector, On-board XDS200 embedded JTAG
emulator is the default type of emulation (SoC JTAG signals are routed to XDS200 on-board emulator).
When external emulator is connected to MIPI 60-pin header, it is automatically detected and SoC JTAG
signals are routed to external emulator.
3.4.1 On-Board XDS200 Emulator
The EVMK2G has on-board XDS200 embedded JTAG emulation circuitry. Hence user does not require
any external emulator to connect EVM with Code Composer Studio (CCS). You can connect the target
SoC in the EVM to CCS through the USB cable supplied in the EVM kit.
3.4.2 MIPI 60-pin Header for Connecting External Emulator
In case you want to connect an external emulator to the EVM, the MIPI 60-pin JTAG header is provided
on-board for high-speed real-time emulation. All JTAG and EMUx signals are terminated on the MIPI 60-
pin header.
The MIPI 60-pin JTAG header supports all standard (XDS510 or XDS560) TI DSP emulators. Refer to the
documentation supplied with your emulator for connection assistance.
EMU pins are pin muxed with DSS (Display Subsystem) and Boot mode pins. The EMU signals are
resistor muxed with DSS signals. A Boot mode buffer is enabled during boot-up to latch the Boot mode
signals.
Resistor muxing between display and trace functionality is shown in Figure 6 and Table 3 .
