When I load a CDF file in batch mode in order to create a PROM file, and I use the "impa.cmd" file created by the ISE software, iMPACT reports the following errors:
"command line: impact -batch impa.cmd
// *** BATCH CMD : adddevice -p 1 -file xcv50
'1': Loading file '.\myfile.bit' ...
INFO:iMPACT:1366 - Reading C:/Xilinx/virtex/data\xcv50.bsd...
ERROR:iMPACT:880 - The bit file '.\myfile.bit' does not have the startup clock set to 'JtagClk'. Please re-generate the bit file with the startup clock option set to 'JtagClk' or toggle the CCLK manually."
The error is valid if you are attempting to create a JTAG programming chain; however, if you are attempting to create a PROM programming file, this error is being incorrectly reported.
This problem is fixed in the latest 5.1i Service Pack, available at:
The first service pack containing this fix is 5.1i Service Pack 1.
