thank you for the suggestion Mr, Torsten.  i remember to have enabled
jtag interface for the PPC on which I am downloading the software, but
still I am having problems downloading the bitstream.

Dear Alan Nishioka,
thank you for the suggestion .
May I know how can I modify the download script , to effect the
downloading bitstream from xps itself.
what is the other procedure if any to download .
which one might be easier to understand and implement for me as a
neophyte.
thanks and regards
vijay

If you are trying to download from XPS, perhaps you need to edit the
download script in etc/download.cmd

When trying to do - what? Updating the procesor bitstream? The message
just tells you that there are only two devices on your JTAG chain (the
Virtex and some flash memory) and you obviously have tried to program
some other device.

I guess you tried to upload an application image to your PPC inside
the FPGA, but perhaps your design does not include the JTAG interface
for that one?

Greetings, Torsten

Hi,

We are trying to run the "Virtex4_PPC_Example_9_1" example program
from EDK9.1.2 that has TestInterrupt.c routine (timer interrupt
driving the
LEDs and UART interface displaying the status.)

The LEDs on the board appear to flash quickly, but we're unable to
speed
up or slow down the clock using the 'f' , 's' inputs via the serial
port.

Software: EDK9.1i on linux 2.6.17, parport jtag, "windrvr6" and
"xpc4drvr"
drivers and devices all there.  We are able to update the bitstream
from
XPS.

We are also able to establish the connection to the virtex-4 Fx12 LC
development board, (the message log says so. ) but we are getting the
following error:

**********************
ERROR:iMPACT:1062 - Can only assign files to devices between positions
1 to 2
**********************
(more of the logs are below.)
**********************

Google says nothing about "files to devices between"!

We ran "impact" through tje command prompt and tried to down
the bitstream, by selecting various combinations of ("download.bit",
"system.bit"), "TestInterrupt.elf " and ("system_bd.bmm" and
"system.bmm").

Has anyone ever seen this?  Any suggestions?

thanks and regards
vijay
