I used the defconfig-atlas to configure my linux build & it works great on my board! Thanks again, but I still have one more hurdle to jump over to kick start this excercise with linux. Messages on my console (I used 'go' on YAMON prompt to start linux): ------------------------------------------------------------------- Root-NFS: No NFS server available, giving up. VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "" or 02:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 02:00 Please advise me the simplest form of starting linux from YAMON prompt after downloading the image(srec) on to RAM. Also please point me to a doc. that talks about the possible parameters when starting Linux. Thanks everyone & Cheers, -Mike. >From: Muthukumar Ratty >To: Michael Anburaj >Subject: Re: Linux for MIPS Atlas 4Kc board >Date: Sun, 4 May 2003 22:49:40 -0700 (PDT) > >On Sun, 4 May 2003, Michael Anburaj wrote: > > > Hi Muthu, > > > > So, I guess then I would have to do, > > > > make menuconfig & choose little endian after "cp arch/mips/default-atlas > > .config". > >small typo, its defconfig-atlas :) > >Yes, if you want to run little-endian.

I used YAMON to net load the image. But I guess it doesnt matter >(redboot/yamon/any).
