Hi All,
Thanks siji. I do take care of that. So I am starting new thread with this.
Kernel compile really testing my patience. I have cross compile the linux kernel 2.6.35 for mips based system. When i loaded that to the device and rebooted the device its booting device but not falling or reaching the shell prompt so because of that I am not able to access the shell.
Can someone help me where I made mistake.

Is fbdev compiled in the kernel?
check if the network is up form an external device.
Hay thanks.
First Happy Diwali to you.
When I was compiling the kernel I got error
/opt/linux-2.6.35/scripts/gen_initramfs_list.sh: Cannot open '/opt/linux-2.6.35/usr/initramfs.cpio' make[1]: *** [usr/initramfs_data.cpio] Error 1 make: *** [usr] Error 2
I have the compiled version of 2.6.28. so I in menuconfig for 2.6.35 i have given initramfs.cpio path of 2.6.28 and compiled the kernel.
But in 2.6.35/usr/ I dont have initramfs (which contain the init and other files required to device bootup) filesystem which is present in 2.6.28
So I copied the finitramfs to 2.6.35/usr/ and again compiled. but no luck with that image as well.
Do I need to create initramfs for this kernel or have to found way to create the initramfs.cpio so that I can boot the kernel without the 2.6.28 initramfs.cpio?
( I dont have clue how can I generate the file.)

Let's back track a little. initramfs-tools is a standard tool in any base install. I am surprised that it is missing. It means that your install is possibly not ok. What distro do you use? My comments are solely for debian (and should be valid for it's derivatives).
Install initramfs-tools the proper way using apt or aptitude.
If you need any module which is not compiled into the kernel until you can mount root, then you definetly need initramfs. Otherwise you dont. Framebuffer (usually) comes much later, so you maynot require initramfs to reach a shell.
( I dont have clue how can I generate the file.)

Hay Thanks Jtd.
Actually I am kernel newbies. I am cross compiling 2.6.35 for mips based devised which has Debian lenny 5.0 on it from ubuntu 11.04 host using mipsel-linux-gcc-3.4.4. I may be wrong. I have tried what you said. Following is the o/p for this.

List the steps you have undertaken to compile the kernel and it's modules.
From above, I suspect you have not built the modules or not installed
them. The kernel modules are installed under
/lib/modules/<kernel version>

Hay thanks Jtd,
I able to generate the initramfs for my kernel but though its compile properly its not reaching shell.
So I reconfigured the kernel with what you have suggested and with the options that I have in my working 2.6.28 kernel provided by RMI.
Its giving me following errors.
CC drivers/mtd/nand/au1550nd.o drivers/mtd/nand/au1550nd.c: In function `au1550_hwcontrol': drivers/mtd/nand/au1550nd.c: 285: error: `NAND_CS' undeclared (first use in this function) drivers/mtd/nand/au1550nd.c:285: error: (Each undeclared identifier is reported only once drivers/mtd/nand/au1550nd.c:285: error: for each function it appears in.) drivers/mtd/nand/au1550nd.c: In function `au1xxx_nand_init': drivers/mtd/nand/au1550nd.c:527: error: `NAND_CS' undeclared (first use in this function) drivers/mtd/nand/au1550nd.c:448: warning: unused variable `boot_swapboot' drivers/mtd/nand/au1550nd.c:590: warning: label `outmem' defined but not used make[3]: *** [drivers/mtd/nand/au1550nd.o] Error 1 make[2]: *** [drivers/mtd/nand] Error 2 make[1]: *** [drivers/mtd] Error 2 make: *** [drivers] Error 2
I think for this I might need to patch Kernel.. By disabling this option in menuconfig I tried it land up with another error..
CC drivers/video/au1200fb.o drivers/video/au1200fb.c:50:39: asm/mach-au1x00/au1xxx_pm.h: No such file or directory make[2]: *** [drivers/video/au1200fb.o] Error 1 make[1]: *** [drivers/video] Error 2 make: *** [drivers] Error 2
I think for this also patch file is needed.
I am kernel newbies. I might be wrong. Can you please tell me what wrong things I did ?
I found out the patches on line (I am not able to get meaning of this ex. @@ -45,10 +45,6 @@ what it means).
