Record #8255
Problem Title:
2.1i JTAG Programmer - Boundary-scan chain test failed at bit position '3'
Problem Description:
Urgency: Standard
General Description:
Using the JTAG Programmer software to configure or perform other JTAG operations
may result in the following error message (or something similar):
Checking boundary-scan chain integrity...ERROR:JTag - Boundary-scan chain test
failed at bit position '3' on instance 'ttt(Device1)'.
Solution 1:
This error is the result of either a broken JTAG chain or noise on the chain.
Most commonly, the cable is not connected properly, a trace is not correct
on the board, other devices in the chain are causing a problem, or there is
a noisy parallel port.
Some debug suggestions are:
1. Try using a different PC, and a different cable.
2. Probe the TAP and make sure the signals are strong.
