Hello Linux powerpc community,

I am trying to move from 2.6.20 kernel to the new 2.6.27.4 kernel. I am not finding my root file system partition with the new kernel.

I had tried this a few days back with no luck, but I think my problem at that time was that my label "nand0" did not match what was in the dts file. I didn't give open firmware much attention because I am using the command line for the partition information in my working 2.6.20 kernel. After spending this much time on it though, I'll take what I can get. Thanks, Joaquin Luna PS U-boot did not accept "ff800000.flash" as the MTD ID and could not load the kernel image with that in the command line. -----Original Message----- From: Scott Wood [mailto:scottwood@freescale.com]=20 Sent: Monday, November 17, 2008 11:59 AM To: Joaquin Luna Cc: linuxppc-embedded@ozlabs.org Subject: Re: command line partition information Joaquin Luna wrote: > I do not list any partitions in my dts file, though I tried and not seen=20 > any change in the behavior.
