The signal err_info
indicates error in the
GZIP/ZLIB compressed file format. If any of the bits go high, this indicates that there is
an error in the header section of the GZIP/ZLIB compressed file. If you get this error, you
can reset the core and run it again with the modified compressed file. For more information
on GZIP/ZLIB compressed file formats, see these links RFC-1950, RFC-1951, RFC-1952.
