Re: [partial-reconfig] Partial reconfiguration with the ICAP

["karel.bruneel@xxxxxxxxxx" <karel.bruneel@xxxxxxxxxx>]

Hi,

Correction: I found the problem(something to do with configuration), but not the selotion. Now (with sp3) when I download a bitstream notting happens (so I thought it workt because I download the partial bitstream that is allready inside). When I download another bitstream still nothing happens, although impact says the programming was succesfull. 

Which version of IMPACT do you use for downloading partial bitstreams.

Regards,
Karel
