Description

When I open the ChipScope Analyzer and attempt to connect to my JTAG chain, the following messages appear in the console:

"COMMAND: open_platform_usb_cable FREQUENCY=3000000 PORT=USB21

INFO: Started ChipScope host (localhost:50001)

ERROR: Client communication thread failed: java.io.IOException: An existing connection was forcibly closed by the remote host

ERROR: Failed to open Xilinx Platform USB Cable. See message(s) above"

I also receive a pop-up message that states the following:

"cse.exe has stopped working."

How do I work around this issue?

Solution

This issue is caused by the User Access Control (UAC) that is enabled on Vista.

Following are some work-arounds:

- Run the Analyzer as Admin on the machine. Browse to the %CHIPSCOPE%/bin/nt; directory -> right-click on the "analyzer.exe" file -> Select "Run as" -> Administrator.

- Disable the User Access Control (UAC). For instructions, please refer to Scenario 3 in the following Microsoft Technical Article:
