Re: [partial-reconfig] SYSACE problems on ML402

[Lu Yi <yilu@xxxxxxxxxxxxxxxxxxxxx>]

Hi, Paolo,

I am using the EDK8.2.02 to build the main system, my board is ML410, the
partial reconfiguration by using CF as the bitstream storage is fine. I
just use XHwIcap_CF2Icap(&MyIcap, "my.bit") to load the new partial
bitstream, it works fine.

Which version of your EDK? Which version of your ICAP module and the ICAP
driver?

regards,
luyi
