12.1 EDK - Attempting to connect to XMD results in "ERROR:EDK:970 - Cse lookup device returned irlen of 0..."

描述

When I attempt to connect to XMD, an error similar to the following occurs:

ERROR:EDK:970 - Cse lookup device returned irlen of 0. ID code is 00000000000000000000001111010011 (0x3d3)"

How can I resolve this issue?

解决方案

This error occurs if there is a non-Xilinx device in the chain. Information about non-Xilinx devices need to be included in the idcode.lst located in the following location:

Xilinx\<version>\ISE_DS\data\cse\idcode.lst

Another work-around is to add the information about the devices in the chain by following the procedure in the XPS GUI, as follows:

Debug -> XMD Debug Options -> JTAG Properties -> deselect the Auto-Discover JTAG Chain Definition and Add Device options.
