When programming an XCF01S/02S/04S PROM device, 5.2i iMPACT fails all configuration operations.
The following problems can prevent correct operation:
1. Syntax error in the "xcf04s.bsd" file.
2. iMPACT treats the XCF01S/02S/04S devices as XC18V00 devices.
This problem is fixed in the latest 5.2i Service Pack, available at:
The first service pack containing the fix is 5.2i Service Pack 3.
A patch is available on the Xilinx FTP site to correct this problem. This patch should only be used with 5.2i Service Pack 2. Please view the archived README file for installation instructions at:
