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

Description

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:509:1.66.26.1 - 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"

Solution

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: 

 

http://www.xilinx.com/txpatches/pub/coolpld/xpla/sr21765.zip
 

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: 

 

%XILINX%/xpla3/data/xcr3256xl.bsd 

%XILINX%/xpla3/data/xcr3384xl.bsd 

%XILINX%/xpla3/data/xcr3512xl.bsd
