RE: [partial-reconfig] Using ICAP drivers with EDK 8.1 or 8.2 (support for Virtex 4 in opb_hwicap)

[Hugo Andrade <hugo.andrade@xxxxxx>]

Hello,

I am using EDK 8.2.2 but with opb_hwicap but the support is only for
Virtex II.

Is there a version of the driver and pcore for opb_hwicap for Virtex 4? If
so, could you please point me to it, or a modification of the original
that supports Virtex 4.

Alternatively, do you know if EDK 9.1 adds this level of support already?

Thanks in advance,

Hugo.

Thanks for the reply,

Yes, I can use the JTAG to apply the partial bitstreams.  I have applied
the bitstreams before starting the microblaze, but I will need to to more
testing to validate the microblaze continues to run when I apply the
bitstream with the JTAG while uClinux is running.

I will take a look at the opb_hwicap drivers in the distribution.  I have
access to previous versions, so I may be able to compare the Xilinx
drivers.  If anyone has experience with 8.1 or 8.2 it would be nice to
here from them them.

Thanks,

David
