Solution 1: The "Duplicate core resource" error indicates that there is more than one copy of some type of data file associated with a particular core. In one customer case, the data files that were duplicated were the .XCD files for a number of pre-existing cores. There were two versions of these files for each, one with the filename in upper case, and the other with the filename in lower case. There has been two different resolutions that have cleared up this error. In one case, the directory in question was simply deleted, to remove the offending files. Then, the update was run again, which restored the files to the original setup. In another case, the problem was a result of installing a CORE Generator IP ZIP file update from a PC over a network to a UNIX workstation running Samba. (Samba automatically converted the PC filenames to lower case for the new versions of some pre-existing cores). CORE Generator treated the two XCD files as duplicates because it is case-insensitive. The problem was detected by doing a recursive listing of the $XILINX/coregen/ip directory. In this case the solution was to obtain a new version of the IP update in UNIX tar.gz format, reinstall CORE Generator, and then reinstall the update over the fresh CORE Generator installation using the tar.gz archive .
