1GB DDR3RAM from micron used in this reference design is not available in the market but only 2 GB.
So, I change mig setting from 1G to 2G DDR3RAM.
but now in SDK there is extra another parameter comes (lmb_subsys_dlmb_bus generic: see mark with red in attachment) and download.bit is not generating in sdk.
What is the reason?
I have also attached microblaze part of the program in attchment.
P.S. While configuring fpga with sdk it configure with exported file from vivado and not with download.bit file but it works when I run from gui.
