4.1i CPLD Hprep6 - Program hangs during JEDEC file creation
ISE and WebPACK hang during the "Create Programming File" phase if a read-only JEDEC file already exists in the project directory. (This can occur if files are copied directly from a CD-ROM.)
To solve this problem, ensure that the existing JEDEC file is not read-only:
1. Right-click on File in Windows Explorer, and choose "Properties".
2. Uncheck "Read-Only".
