Physical Connections
2.1.1
Connection to JTAG Programming Cables
The JTAG Programming Cables comes supplied with a 14-pin connector and ribbon cable assembly.
Using this cable, the JTAG Programming Cable can be connected to either P1 or P4 of the JTAG
Breakout Board. The P1 and P4 pinout is given in Table 1.
If you are using a V01R1 Bare Board PCB Issue of the JTAG Breakout Card (see Figure 1) you are
required to use the supplied cable labeled ‘JTAG’ rather than the standard point to point cable that is
supplied with the Xilinx JTAG programming tool
The JTAG Programming Cable connects to the JTAG breakout board via P1 or P4 using the correct
point to point cable depending on the bare board PCB number or the flying leads. Both connectors
have the same pin-out this is given below in Table 1.

Table 1: Debug & Breakout Card P1 & P4 Pinout
The JTAG Programming Cables typically connect to your chosen programming host via a standard
USB cable.
2.1.2
Connection to FPGA Card
The 250-SoC MPSoC Card is populated with a single row 24-way ZIF connector (J5) located on the
bottom side of the assembly. A ribbon cable is used to connect the 250-SoC to J1 of the JTAG Breakout
Board.
