Problem starting up linux on Nios II Cyclone

[Altera_Forum]

Hi everybody, despite my earlier post I now have a big problem with trying to start linux. The kernel and filesystem compile ok, with a few warnings on the way. What I get when I try to log on through Nios II SDK shell is:

The linux is the same linux I got from this website, and the .ptf and .sof I'm using are from the Microtronix Eth -USB Expansion kits CD. I used the Quick Start Guide as a reference in setting up the kernel and the filesystem, so nothing special was done.  Anyone have any idea what's going on?

There is a very helpful uClinux wiki site for blackfin, and it apply to nios2 as well. http://docs.blackfin.uclinux.org/ (http://docs.blackfin.uclinux.org/)

So... after a few false starts I tried working on linux. The results weren&#39;t that great either. First of all, "make menuconfig" didn&#39;t work. It just stopped after a few lines and despite waiting patiently for something like 10 minutes, nothing happened. "make config" at least went further, but it didn&#39;t let me customize the kernel settings. Also, linux_hwselect probably didn&#39;t work either, because, despite running it ok, I got errors later on declaring I should run it. 

 Too bad I&#39;m running so short on time, otherwise I would try setting up a different linux distro to work on, as I&#39;m suspecting something fishy is going on with the OS...
