Hi Danish, Thanks for the guidelines. I'm still struggling to get it to boot. I'm not sure how to implement step 10 of your guidelines. How do I 'include *.qip file' in my Quartus project? I'm using Quartus 12 sp2. There is no include option in Eclipse or Quartus. I finished up selecting Add/Remove Files in Project... in Quartus but you said 'From mem_init folder include *.qip file in your Quartus project'. Please advise?
