[U-Boot-Users] boot kernel hanags with u-boot

[rameah nathan]

Hi ,
   I have booted my kernel (montavista) using flattened device tree that i
supply as third argument in bootm command through U-boot .But kernel hangs
after uncompressing the kernel and ramdisk image and i have attached the
screen shot as attachment , of it for your reference.Infact ihave checked
IMAP_ADDR and CFG_IMMR both are same in my case.Can anyone help me out where
exactly i am going wrong.I could be of great help if anyone reply me ASAP as
we already running out of time.
Regards,
K.V.Ramesh

As we don't have the sources for your kernel tree, you cannot hope for
much help on this specific hangup here (apart from being offtopic on
the U-Boot mailing list).  

Attach a debugger or ask the guys you have the kernel from.

Cheers

You need a patch to u-boot to fix initrd/fdt loading.  As a
workaround, you can try:
setenv initrd_high 0x1000000

This will restrict the ramdisk to the first 16M, and thus the flat
device tree, too.  You can play around with that number.  You want to
make sure that the start of the initrd image is within the first 16M
(address < 16M) of memory. If you can't do that, you'll need to grab
the patch to fix that bug.

It can be found here:
http://opensource.freescale.com/pub/scm/u-boot-85xx.git@the top of
the tree.  You can use gitweb to grab it, too:

Or use u-boot-testing, which should have this incorporated  (or  even
mainline, as I will merge -testing into main in the next few hours).

Boss, n.: According to the Oxford English Dictionary, in  the  Middle
Ages  the  words  "boss"  and "botch" were largely synonymous, except
that boss, in addition to meaning  "a  supervisor  of  workers"  also
meant "an ornamental stud."
