7.1i iMPACT CoolRunner XPLA3 - Programming/Blank Check of XPLA3 devices fail with "JedecReader.c:119:1.42" or "iMPACT:1779 - MISR" error


General Description: 

When I am programming a CoolRunner XPLA3 device, iMPACT displays the following errors: 


"EXCEPTION:iMPACT:JedecReader.c:119:1.42 - Data mismatch." 

"ERROR:iMPACT:636 - performOperation() failed!Device # selected" 

"ERROR:iMPACT:1779 - Can't find this register MISR" 

"EXCEPTION:iMPACT:BsdlStorage.c:509: - Data not found." 


Also, during a Blank Check operation, iMPACT fails with the following error message: 


"Failed at address, 0'1' : Part is not Blank"


The error is caused by a problem with the Boundary Scan Description (BSDL) file. 


The proper BSDL files can be downloaded from the link below: 



To install, simply extract the" .ZIP" archive to your XILINX directory. If using WinZip, ensure that "Use Folder Names" is enabled. This will overwrite 3 BSDL files:
