Thank you for the answers. I just feel that the instructions are misleading.
"Here you can run Linux with your Altera DE2-115"-
Really? But how?
I beg your pardon that I was negative. I know it's not a perfect world. But I really tried everything and I'm a bit disappointed that there are no more ways to build the thing.
I bought the Altera FPGA for my own money because I was enthusiastic. Now I feel disappointed. I'm not a noob with building source code. There are also others who had the same problem.
I feel that the whole idea of sustainable software is just bogus if we can't use code just because it's a few years old.
I really tried everything and I asked only when everything else failed. The manual isn't very good either: What is meant by "incorrect" and why did I buy something "incorrect"?
I realize that many things must work to run an os with my Altera DE2-115. But I already could run the os from my instructor at the university with no problem whatsoever.
Anyway it was good to learn but I would like to come the whole way and boot a somewhat mature shell, at least the sash shell and preferably a shell that is targeted for real usage.
