HI,

I am trying to build the custom kernel from the kernel source which is
inside the Android source dir. To build the kernel I just followed the
steps given in the following thread

http://groups.google.com/group/android-platform/browse_thread/thread/e24eb299383e9103/34e8c50b2b50efa3?q=How+to+build+kernel+for+emulator+%2B+android#34e8c50b2b50efa3

In that they mentioned that we can start the emulator with the
following command.


out/host/linux-x86/bin/emulator -kernel kernel/arch/arm/boot/zImage -
system out/target/product/generic/ &

But when I try to boot upi with that I got few errors. at the end I
end up with the following command to start the ematulor with the
prebuilt kernel,

$ ~/android_cupcake_old/out/host/linux-x86/bin/emulator -ramdisk
ramdisk.img -sysdir . -system system.img -initdata userdata.img -data
userdata.image -kernel ~/android_cupcake_old/prebuilt/android-arm/
kernel/kernel-qemu

So now the above command launching the emulator fine with the pre-
built the kernel.

So now I changed the command to launch the emulator with the new built
kernel. Here is the command.

$ ~/android_cupcake_old/out/host/linux-x86/bin/emulator -ramdisk
ramdisk.img -sysdir . -system system.img -initdata userdata.img -data
userdata.image -kernel ~/android_cupcake_old/kernel/arch/arm/boot/
zImage


So here I am not able to see anything. The terminal looks like it's
booting the emulator. But there is nothing coming up. and also there
is no messages.

Please give me some pointers and suggestions to make my own build of
the kernel and launch the emulator using the custom kernel  not with
the prebuilt.

Thanks
Raj
