Hi Paul,
Appreciate the feed back. My responses are in line below..

Hi All,
We have a custom Board which is based on mpc8349EMDS which is based on
e300.
I got the Toolchain downloaded using poky-dora-10.0.0 project which
supports e300 core
Now when I cross compile Linux kernel ver 2.6.32 the system boots up
and
works fine.
But when I cross compile Linux kernel ver 3.X the target reboots just
after uncompressing the kernel with the error
ERROR: Failed to allocate 0x3dbd bytes below 0x800000.
device tree - allocation error
I am using the same device tree for both kernel versions !!!
Why would you use the old device tree on the new kernel? The
8349EMDS is in mainline IIRC, and hence you aren't tied to the
old dts file.
I am not using old device tree. I created one which is based on mpc834x_mds.dts
in 3.4.36 kernel. Attaching it for your ref..
When I use this newly created one with 2.6.32 kernel it works fine. Hence I
mentioned I was using the same device tree for both kernels!!
OK, so new dts works on the old kernel. Good to know; I'd got the
impression you were using the old dts on the new kernel....
What is the u-boot version?
U-Boot 2009.08 (Nov 11 2013 - 12:37:05) MPC83XX
Not super new, but not so ancient as to probably be the problem.
How much difference in size is there between the two uImage?
-rw-rw-r-- 1 platform33 platform33 4055829 Dec 19 14:21 uImage4hd12_3x
-rw-r--r-- 1 platform33 platform33 1653704 Dec 13 13:30 uImage4hd12_2x
Is it this size diff causing this issue ??
Any idea what may be the reason for increase in 2.5 MB ???
Ouch. That is a _huge_ difference. I think objdump and nm are your
friends here -- or even "file" -- with that size difference, I wonder if
you've stripped the newer image...
Does the 3.x image work if you turn off some stuff to reduce
the size? (you can turn off essentially all device drivers
other than serial for this test)
I tried using a dts with just serial ports and that failed too!!
No, you misunderstand ; the idea was to strip options from the kernel
config file to reduce vmlinux/uImage size; you never want to remove
entries from a dts, as if they aren't used, they are inert.
What happens if you take a default yocto mpc8315 BSP, and enable
the mpc8349EMDS in that kernel config (one kernel can support
multiple mpc83xx boards, IIRC -- haven't booted one for a while...)
I tried enabling CONFIG_MPC834x_MDS=y in .config but I still have the same
error
OK, well your giant increase in uImage size is probably the root cause;
you need to figure out what happened there.
Good luck,
Paul.
