Dear all, I finally run Linux on OR 1200 in rtl simulator and custom own fpga board. There are few problems: 1. As You pointed some registers were not initialized so there are some X signals, and this was a main problem. 2. When I did correct initialization I noticed that I also made a mistake when changing ram memory model Thanks for your help
