KERNEL_NOT_BOOTING: Console_setting_problem

GoogleGroups
1

hello to all,

yesterday i compiled a kernel which i got from "git clone
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git
linux-omap-2.6" this link and followed steps given in
"http://elinux.org/BeagleBoard#Linux_kernel" this link.
the that i found was there was no any "omap3_beagle_defconfig" file
under arch/arm/configs. I downloaded kernel source 2.6.33.1 and found
this defconfig in that so i copied it in the linux-omap-2.6 kernel and
followed these steps:
1. sudo make distclean
2. sudo make ARCH=arm omap3_beagle_defconfig
3. sudo make ARCH=arm menuconfig
3. sudo make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
4. sudo make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- modules
5. sudo make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
modules_install
6. mkinitramfs -o initrd.img-2.6.36-rc7-08946-g99cf630
2.6.36-rc7-08946-g99cf630
7. mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs
-d ./initrd.img-* ./uInitrd
8. then copied these two files in the flash card.

On booting the beagle(C3 version) this is the output i got:

Starting kernel ...

It stuck there only. It seems to me that it's not able to recognise the
compressed kernel format but the format is default which is gzip. I'm
unsure about initird that it is proper or not.
Can any one tell me where am i goin wrong .

Also one more thing i want to know how can i check the same kernel on
qemu. i tried to use this kernel on qemu but it was throwing a error
that address out of RAM or ROM.

That 2.6.33.1 config is too old, with tmlind's tree use

make ARCH=arm omap2plus_defconfig

Regards,

also beware omap git has changed the name of ttys, wrong tty in boot
args causes a problem like that.

Thanks ROBERT. But what i did i copied omap3_beagle_defconfig from the
new kernel source tree in this tmlid's tree and compiled my kernel.
And it compiled fine.

Problem was the console only, that was rectifed by changing ttyS2 to
tty02. thanks can for ur suggestion

also beware omap git has changed the name of ttys, wrong tty in boot
args causes a problem like that.

One more thing how can i use this uImage for emulating in qemu. i tried
but i got some error regarding the starting address looked by qemu. Can
anyone help me on this.
