ChipScope 6.2i fails to find LPT2, and I receive the following messages:
"ERROR: Open (or Close) Cable Failed. Check your host connection to the cable and try again."
"ERROR: Failed to open Xilinx Parallel Cable"
For LPT2, ChipScope uses the same variable environment as iMPACT.
To ensure that ChipScope detects the cable on LPT2, set XIL_IMPACT_ENV_LPT2_BASE_ADDRESS=xxxx (xxxx will be the address of your LPT2, for example C400).
To select the LPT2 in ChipScope Analyzer:
ChipScope's menu -> "JTAG Chain" -> Xilinx Parallel cable -> Port -> LPT2.
