The "avail" of ICAPE3 for partial reconfiguration do not become High on UltraScale+.

Hi,

I have tried a partial reconfiguration with PRC IP and ICAPE3(ug570) on UltraScale+.

I have succeed to publish a reconfiguration trigger to PRC IP and verified PRC IP started to fetch new bitstream.
But PRC IP stopped fetching it.

I have seen PRC IP and ICAPE3 signals with ILA IP and verified that "avail" signal of ICAPE3 is low.

But the "avail" became High after power on and PRC IP did not stop fetching a new bitstream on the simulation.

Could you tell me why the "avail" did not become High ?

Sincerely,

Hi,

 

Avnet told me that PS have to release PCAP in order to "AVAIL" of ICAP become high.

I tried to fix FSBL source code to set pcap_pr low and have verified the "AVAIL" became high.
