Modifying Xilinx ML605 for Direct JTAG Access
Version 30-Apr-2021
Introduction
The ML605 board does not have a JTAG connector but only a USB-JTAG bridge that is connected to the
host via a standard USB cable. For debugging with TRACE32, the ML605 needs to be modified in order to
make the JTAG signals accessible. This document describes this modification.
The modification was tested and found working by Lauterbach but there is no guarantee
whatsoever. In particular be aware that soldering may cause permanent damage to the board.
Requirements
The following items are used for accessing the JTAG signals on ML605:
•
EVB Xilinx ML605
•
Xilinx HW-FMC-105-DEBUG daughter board. The daughter board is not strictly required but
serves as a convenient access to the JTAG signals of the main board.
•
A Lauterbach “JTAG to Xilinx ML605” adaptor. It may be replaced by a custom-made adaptor. For
details, see the section “Pinout of the JTAG to Xilinx ML605 adaptor”.
•
Soldering material
NOTE:
While the board is modified for JTAG access, the USB-JTAG bridge is disabled.
See section “Using ML605 without USB-JTAG bridge” for more information.
