XmdStub fails when connecting via JTAG.

Apr 21, 2008 0 Replies

Hi, I would like to know if anyone has received this message when he tries to start XMD.



This message appears some times and I have to close Xmd Windows and start again so the message doesn't appear. I use Xilinx Parallel IV Cable and version 8.2 for EDK.



Thanks.
