[partial-reconfig] ICAP_Virtex4 using 32bit@100MHz

["Mati Nahshon" <mati.nahshon@xxxxxxxxx>]

He everyone,

It seems the group is not active for quite a while, is there any one still interested in partial reconfiguration?

Regarding my issue…

I have found the following entry in the archive with no answer:

I'm trying to use the Virtex-4 ICAP component in 32-bit mode to read the Device ID of my FPGA. It's not working. A picture of the chipscope output can be seen here:

Can anyone tell me what I am doing wrong?

I wasn’t able to download the picture but I have the same problem.

Some more details: 

To investigate the issue I built a design that only tests ICAP.  I tried it in many different options.  The 8 bit option seems to work.  The funny thing is that even when I set the bus witdth to 32 bits the 8 bit behavioral still works…

If any one is interested I can share some more interesting stuff I found out.

Please help…

Thanks,

Mati
