I'm trying to learn Qsys and Quartus II to define a system that can run linux according to this document:
http://uuoc.org/uClinux_nios2_custom_hardware.pdf
But I'm running into problem as the document is not detailed enough. I get errors from Qsys and Quartus and I'm not exactly sure whether I'm doing the right thing.
I tried to add the SDRAm but I was not successful, could you please help me understand how to do it?
