14.5 XPS/SDK - Cannot connect to MDM through XMD on Virtex-7 1140T and Virtex-7 2000T devices


If I attempt to connect to the MDM in XMD, an error similar to the following occurs:

XMD% connect mb mdm

JTAG chain configuration
Device   ID Code        IR Length    Part Name
 1       136bf093               24        XC7V2000T
 2       136bf093               24        XC7V2000T
 3       44256093              10        XC6VLX550T
ERROR: Could not detect MDM peripheral on hardware. Please check:
        1. If FPGA is configured correctly
        2. MDM Core is instantiated in the design

How can I fix this issue?


This is a known issue on the Virtex-7 1140T and the Virtex-7 2000T devices. To work around this issue, install the patch at the end of this answer record.

To install the patch, unzip the file and copy the xmd.exe file into the EDK install directory, similar to the following:

For Windows 32-bit

For Windows 64-bit

For Linux 32-bit

For Linux 64-bit

For 14.4, the patch also requires an updated version of the "ibSdkHwDb.dll" file to be added to the EDK install directory.

To do this, copy the "libSdkHwDb.dll" file from the relevant location in the ZIP file.

For example:

For Windows 32-bit
Copy from lib/nt to C:\Xilinx\14.4\ISE_DS\EDK\lib\nt

For Windows 64-bit
Copy from lib/nt64 to C:\Xilinx\14.4\ISE_DS\EDK\lib\nt64
