Dear xenomai,

I compiled the the kernel and builded the uImage . I transfered the uImage
to FAT partion of SD Card  and the directories DEV and usr (That generated
due to make DESTDIR) to root filesystem of the sd card.

i started booting from sd card . It giving me the below result and freezing.
Iam seeing nothing on terminal after this .

And i thought whether my uImage that i created was crashed , so thought of
building it again .
when i run the make uImage , it giving me error No rule to make target
uImage . stop

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
O=/home/balijepalli/pandaboard/build uImage
make: *** No rule to make target `uImage'.  Stop.

then i ran
test06:/home/balijepalli/pandaboard/ipipe-gch# make ARCH=arm
CROSS_COMPILE=arm-none-linux-gnueabi- O=/home/balijepalli/pandaboard/build
omap4_panda_defconfig
make: *** No rule to make target `omap4_panda_defconfig'.  Stop.

so i went to to 1st step to check scripts/prepare. kernel.sh as below
 test06:/home/balijepalli/pandaboard/xenomai-2.5.6#
scripts/prepare-kernel.sh --linux=/home/balijepalli/pandaboard/ipipe-gch
--arch=arm
scripts/prepare-kernel.sh: line 350: linux_: command not found


 i checked this scripts/prepare.kernel.sh by downloading the xenomai again
but i got the same error.




Thanks for the help

It means the kernel encountered an error before the console is enabled.
Enable CONFIG_EARLY_PRINTK and pass earlyprintk on the kernel command
line to know what the problem is.

Note that since I told you to download ipipe-gch, I finalized the port
of the I-pipe patch on panda board. So, if you download the ipipe-gch
git again, you will be able to enable CONFIG_SMP.

I do not know what to do from this explanation. You are giving us either
too much or not enough information.

Some ideas:

The prepared kernel should be built in the sources directory or in its
own build directory. And this is an exclusive or, if you start mixing
out-of-tree build with in-source builds you start having problems.

The omap4_panda_defconfig does not exist in the I-pipe patch, you have
to configure the kernel manually (start from omap2plus_defconfig, and
disable all options related to other omaps than omap4).

You should not try and prepare a kernel which has already been prepared.
