The schematics of the EVB Xilinx ML605 are available from

The jumper J24 on ML605 cannot be used for JTAG debugging because its JTAG lines are not
connected to the SysACE and FPGA. According to a comment in the board schematics it is only
intended for reprogramming a CPLD during production testing.
