When I program XBR (CoolRunner-II) devices with the "On The Fly Pattern" (OTF) enabled, iMPACT reports the following error:
"ERROR:iMPACT - '1':Done bit could not be programmed correctly."
However, the "Activate On-The-Fly Pattern" still works.
This problem has been fixed in the latest 6.1i Service Pack available at:
The first service pack containing the fix is 6.1i Service Pack 1.
