Description
Keywords: XMD, Error, Cse, lookup, IDCODE
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?
Solution
This error occurs if there is a non-Xilinx device in the chain. Information about non-Xilinx devices should be included in the "idcode.lst" located in the following location:$ChipScope_install\xilinx\data\chipscope\idcode.lst) or ($ISE_Install\data\chipscope
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.
