Configuring Multiple V2Pros with Same Bitstream

Hi,
I am trying to configure 8 Virtex 2 Pros (V2P7) (with the same bitstream) on
a single board.
I will use the the Master Serial programming mode.
Are there known issues which i need to worry about ?
Any documentation available ? Prior Experience ?
Thanks in advance,
Adarsh
 
One of the V2P7 chips is the master and drives CCLK to the SPROM and to
the other V2P7s, the other seven V2P7s must be in slave serial mode and
receive CCLK. Al Din pins are tied together and thus receive the same
bitstream from the SPROM..

I forgot to mention:
All INITbar outputs are connected together, with a 1 kilohm pull-up
resistor, and hold the SPROM reset while that common pin is Low.
This guarantees that all chips wait for the slowest device to come out
of power-on reset (POR)

Thanks Peter,
Hopefully I should be able to program the V2Pros now.
