[partial-reconfig] "Modularization" of Microblaze flow

[Dimitris Syrivelis <jsyr@xxxxxxxxxx>]

 Hello all,
  
   Has anybody achieved module-based dynamic partial reconfiguration through 
ICAP on microblaze platform? 
    Iam aware of the uClinux hwicap driver that John Williams has written -so 
one may use uClinux to download bitstreams - but  it seems impossible to 
create a partial bitstream  (not differenced based - an entirely new module).    
 
My main concerns are:
      -Can the FPGA unchangeable pin assignment ( used to interface off-chip 
peripherals RAM-flash etc) on a specific platform be the module-based-DPR 
bottleneck? (i have read that pins should be within the module area)
     - Does XCV1000 have enough resources to constrain the basic uclinux-auto 
(for instance) setup in order to create available frames for DPR? I have 
opened system.ngd of uClinux-auto using the Xilinx floorplanner and it seems 
that it has "conquered" 80% of the device :-).

  Any information would be very much appreciated. If there is an ongoing 
effort on this i would like to help in anyway i can.
 
 Thanks a lot 
   
          Dimitris
