Custom Kernel freezes on "Uncompressing Linux... done, booting the kernel."

Hi all,
it is my first message on this group.
I recently have acquired a BeagleBoard-Xm rev B. I am playing with it.
Currently I can run Ubuntu 11.03 on it (with the help of the Wiki).
Now, I want to compile my own kernel...
I download kernel sources (from kernel.org), omap patches and
defconfig (from http://rcn-ee.homeip.net:81/dl/omap/patches/ ), and I
use cross toolchain from Codesourcery (Sourcery G++ Lite 2011.03-41).
My development desktop works with Fedora15.
I apply patches and compile kernel in order to obtain a uImage. When I
try to boot with this new image, the board systematically freezes on
"Uncompressing Linux... done, booting the kernel." message...
Have you an idea?
Thanks in advance for your help,
Best Regards,
Pierre

depending on kernel version, you may have to set the console to ttyO2
(thanks to those people who hard encoded extended serial interface
capabilities into a different device file name).

Hi Pierre,

To help you, we need a couple more pieces of info..

What version of the kernel/patchset are you building?
What are your current bootargs?
and possibly, what did you change in the defconfig..

Regards,

Meanwhile, note that there is an alignment issue with the code Sourcery 2011.03-41.

Thanks for you help,
I found this page : http://maxgalemin.blogspot.com/2011/05/linux-kernel-2639-codesourcery-201103.html
Indeed it solves my issue!!! :slight_smile:
So, in order to compile, I need to add in my 'make' command line :
EXTRA_CFLAGS=-mno-unaligned-access
I hope that it can help someone.
Bye.
