hi

 

this is a problem with integration of your edk subsystem with ise. you should follow the procedure given in http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/edk_ctt.pdf

hi,

 

how are you integrating the memory controller? rather than configuring the memory controller in ISE, can you use Base System Builder wizard to add the memory controller?

hi

first of all I do not want to add mcb in BSB as I want to add it as my customized IP

I have followed the following steps:

1)Generated MCB from ISE 

2)Creted IP in xps

3)Imported the IP and added the .v(of ddr2 generated in ISE) and modified .mpd and .pao.

Regards Preet
