wired downloading bitstream to spartan2

HI, I have a Avnet Spartan2 board, if I download the the .mcs (prom file) comming with the board to it, it seems everything is OK. Then I build my design, went through the implementation flow, and I run a script to run impact.exe,

setMode -bscan setCable -p lpt1 addDevice -p 1 -part xc18v01 addDevice -p 2 -file download.bit program -p 2 quit

but what I see is at the end of its running is like this,

'2':Programming device...done. INFO:iMPACT:579 - '2': Completed downloading bit file to device. INFO:iMPACT:580 - '2':Checking done pin ....done. '2': Programming terminated, Done did not go high.

----------------------------------------------------------------------

---------------------------------------------------------------------- Done.

Do you know what might be the problem? Note that I have the same P4 download cable, JTAG cable and power supply.

Thanks, Jim

Hello Jim,

think You want to program a ser. PROM. Did YOU already try to create a *.mcs file for the serial PROM instead of a *.bit file?

with best regards,

If you are programming the Spartan2 device after the xc18v01 has been configured then the initiation of the boundary-scan configuration of the Spartan2 (program -p 2) also initiates configuration of the Spartan2 from the xc18v01and results in a configuration data conflict within the Spartan2.

There are several ways to work around this problem either >HI,
