Eclipse error messaging sometimes isn't clear. First make sure that it reads the .sopcinfo file that correlates to your design. Then if things don't seem to behave, make the onchip code storage memory as large as you can and trim later. If you run out of code space, Eclipse isn't that clear about telling you so. Add a JTAG UART to your setup that you show in your schematic and try the hello_world_small template might be a good place to start.

Eclipse read my .sopc info file. When I compiled my source code as well, it was successful. I tried both .c and .s and I got successful compilation. All I am attempting to do in the source code is to write to the Avalon bridge in order to initiate an Avalon write transaction to my external RTL component that the nios will connect to. Even though the code was correct (writing to the base address of the avalon bridge) I would not see a write transaction on my Avalon master. I would also see all those random, and invalid read and write transactions on the onchip data and instruction memory. Most of the had the data 0xDEADBEEF, so I am assuming something is going wrong, I just cant seem to find it!
Thanks
