ICAP with microblaze

[Arun]

Hi,

Does any one used ICAP with Microblaze?
I am trying to read some frames using documentation from XAPP662.
I modified the ipif core(Xapp661 reference design) given by xilinx to
work with OPB. Everything is working fine in simulation, I mean
signals to ICAP are going as in the Xapp662 document. while
implementaion I am getting just zeros. I used virtex2v1000, with 24MHz
clock. can any one give me some suggestions. Any help will be most
appreciated.

Thanks
Arun

I recommend you use the OPB_XHWICAP core that ships with EDK6.2... it's
got some good supporting drivers that wil help you get going more
quickly than rolling your own.
