Hi Stuart,   Thanks for the information.   gpp access was resolved.    I was successful in building the linux 2.6.11 using the ltib and able to bring up the MPC8360 EMDS.But, I still face the problem for linux kernel 2.6.19 and 2.6.20.   When I tried using ltib in the bringing up the board.   The MPC 8360 board keeps rebooting after downloading the image Power PC Kernel Image(uImage) and Power PC RAMDisk Image(rootfs.ext2.gz.uboot)  build by the "ltib"     Please clarrify on the same.Thanks in advance.Regards,Nanda  On Thu, 20 Nov 2008 18:40:36 0000 Stuart Hughes wroteHi Nanda,This is happening because you don't have access tohttp://www.bitshrine.org/gpp for some reason.If LTIB needs to download sources to build a package, it will get themfrom bitshrine.org.

Hi Nanda,

You'll need to get help from the kernel experts with this issue.

I'm not a kernel expert and don't know what failure you
are seeing here, but I might observe that 2.6.19 and .20
are two years old, and 2.6.11 is more than 3 years old.

If you think we, collectively, haven't improved things in
that time period, please, complain about 2.6.11, .19, and .20.

If on the off chance you think things *might* have gotten
better due to a *bit* of development effort over the past
three years, you might try installing a modern U-Boot and
a modern Kernel.

Thanks,
jdl

I would strongly recommend switching to ELDK from denx.de and the latest 
released (or tip-o-the-tree) u-boot.  This will allow you to build and 
boot the latest kernel with a flattened device tree (FDT).

ELDK:
   <http://www.denx.de/wiki/DULG/ELDK>
   <http://ftp.denx.de/pub/eldk/>
Specifically:
   <http://ftp.denx.de/pub/eldk/4.2/ppc-linux-x86/iso/>

u-boot:
   make MPC8360EMDS_HOST_66_config && make

linux:
   Start with: arch/powerpc/configs/83xx/mpc836x_mds_defconfig

Trying to use an old u-boot and old toolset with a recent kernel isn't 
worth the headaches.  The ToT supports the MPC8360EMDS directly.

Best regards,
