Hi,

I'm trying to boot linux on or1ksim on a Ubuntu 14.04 host machine.
I followed the steps mentioned in this link http://electria.metropolia.fi/2013/12/linux-on-de0-nano-part-i-simulator/

Untill the build of the linux I was able to reach.
When try to run linux on or1k sim I get the kernel panic error.
Following is the log on xterm window:

I have tried looking into linux documentation but I have no idea how to proceed. Can anyone please help me out?I'm new to openrisc.
And yes I tried the suggestions made here http://opencores.org/forum,OpenRISC,0,4350 but couldn't find this git://openrisc.net/jonas/bakiri/linux git repo.

Thanks&Regards,
Vidya
