Re: [partial-reconfig] Problem with partial bitstream

[David Kramer <kramer@xxxxxxxxxx>]

Hello,

I've got the same problem as you.
I also tried this tutorial. (Has anyone tried this tutorial with ISE 
7.1i? The design only ran through with ISE 6.3sp3 here) But got the same 
problems.
After adapting the design to the Virtex2pro in the ML 310 (e.g. new 
constrains, other Pins, new Clk_div, ...), the design ran through the 
whole process without any error message. All full bitstreams work as 
they should. But the partial bitstreams doesn't change anything. and I 
don't know why.

I also got this problem with an difference based approach earlier. After 
changing the design in the FPGA Editor and running bitgen with the 
option -r, I got an partial bitstream. (50 Frames had to be 
reconfigured) The full bitstreams work quite well, but the partial 
bitstream didn't changed anything. All it has done was causing some 
trouble with iMPACT after reconfiguring the FPGA with it.

Any help would be appreciated!

Best regards,

David Kramer
