hwicap can be used in the virtex4

hi everyone!

hwicap can be used in the virtex4 ?        I try to use it but the EDK
7.1 tell me :

error: MDT - opb_hwicap (opb_hwicap_0)
-C:\copy_project\XC4VFX12\EDK_Projects\Custom_Peripheral\system.mhs:321
- not
supported for architecture 'virtex4'

what wrong with it? who can tell please that is very important to
me!!!!

thanks advance!

ubelievable, even in EDK 8.1 SP2 hwicap is only supported for V2/V2Pro
so you need to edit the ipcore to get it working on V4 :(

else , if there have another solution for charge the bit for partial
reconfigration to remplace the  icap??

Have you tried adding virtex4 to the list of supported architectures
in:
EDK/hw/XilinxProcessorIPLib/pcores/opb_hwicap_v1_00_b/data/opb_hwicap_v2_1_0.mpd

That is, change
OPTION ARCH_SUPPORT = virtex2:virtex2p
to
OPTION ARCH_SUPPORT = virtex2:virtex2p:virtex4

I don't have 8.1 and am not using hwicap, so I have not tried this and
don't know if it will work.

Hi Alan,

This would only work if the ICAP in Virtex4 operated the same way as in
Virtex2/Virtex2p.  Maybe they are not the same and this is why the
ARCH_SUPPORT doesn't include Virtex4.

in the doc of liberary guid of vitex4 where we can find the model hdl
and symbole of ICAP so I'm sur icap is in the virtex4 but hwicap!!!!!!!
no idea! maybe there will have another version ip will  be used !!!

I think that is the reason maybe the new version will different than
the old

yes, ICAP is OK in V4, its just the EDK that has the ip cores not updated 
with V4 support :(

Does someone have a working design using an ICAP in Virtex-4 ? We are
trying to send a difference-based partial bitstream to it by using
GPIOs but it doesn't seem to work. (The bitstream is ok, it works in
iMPACT by JTAG)
