Hello, it's me again...

I figured my overly minimalist Nios design could be the problem. I followed phillip lutz's tutorial (http://www.hs-augsburg.de/~carcass/nios2-uclinux/uclinux_nios2_devicedrivers_and_testapplication_documentation.pdf) for porting ucLinux to the altera de2 board. It also freezes at "booting kernel...".

I customized the DE2_NET example, as he advises. I also checked for IRQ 0 in the design. I ran:

make xconfig && make vendor_hwselect SYSPTF=/pathtoptf/ && make romfs && make && make linux install

then

nios2-configure-sof DE2_NET.sof && nios2-download -g zImage && nios2-terminal

What am I doing wrong? He says that it could also be a result from a broken initramfs image. Shouldn't make linux install take care of that?
