Hi, 

 seems that you didn't choose the right branch for it. if you use the noMMU version  the output of git branch should be that test-nios2 is selected. so this must be selected in the 'uClinux-dist' as well as in the 'linux2.6' folder. I don't know if the noMMU also works with the "trunk"-branch from "nios2 linux distribution". Even if this is possible the command make vendor_hwselect is not used in the "new" distribution.  Urmel
