6.2 EDK, JTAGPPC v1.00.b - The MPD file has incorrect INITIALVAL keywords

Description

Keywords: Proc, JTAGPPC, INIT, VAL

Urgency: Standard

General Description:
The MPD keyword for default values is as follows: INITIALVAL

The MPD file has the following: INITIAL and INITAL

PlatGen ignores these values, and these inputs are grounded if they are not explicitly connected. Usually, the result is a complete JTAG failure.

Solution

To avoid this issue, connect the TRSTNEG and appropriate HALTNEG_# explicitly.

This problem is fixed in the latest 6.2 EDK Service Pack, available at:
http://www.xilinx.com/ise/embedded/edk.htm.
The first service pack containing the fix is EDK 6.2 Service Pack 1.
