linux 2.4.x or linux 2.6.x means the linux 2.4 kernel series such as linux 2.4.20,linux 2.4.21........... and so on similarly for linux 2.6.x means linux 2.6.8 or linux 2.6.9,2.6.11 etc.............

here i am providing the steps i followed while building the kernel :-

1) building tool chain

#tar -xjvf /home/prafulla/arm-linux-gcc-3.4.1.tar.bz2

#export PATH=/usr/local/arm/3.4.1/bin:$PATH

2)building kernel

#tar -xjvf /home/guest/prafu/linux-2.6.11.3.tar.bz2

#cp /home/guest/prafu/patch-2.6.11-rc3-omap1.bz2 ./
#bunzip2 patch-2.6.11-rc3-omap1.bz2

#cat ../patch-2.6.11-omap1 | patch -p1

#make omap-osk-5912-defconfig

#arm-linux-objcopy -O binary -R .note -R .comment -S arch/arm/boot/compressed/vmlinux linux.bin

#u-boot-1.1.1/tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10000000 -e 0x10000000 -n 'linux kernel image' -d linux.bin.gz uImage.cc

once made this i have downloaded this image to the board by using the kermit protocol through hyperterminal . and in uboot i used the command loadb 0x10000000

here my bootargs are

console=ttyS0,115200n8 noinitrd rw ip=off root=/dev/mtdblock4 mem=30M

afterthat i copied to the flash using cp.b 0x10000000 0x100000

memory location in flash .

and used bootm 0x100000

then afterthat i got the bad crc error

is this information is sufficient or if u want i can provide my configuration details also .

is the configuration of kernel is dependent on u-boot. how it will effect ??

what is the effect of bootargs on kernel?? is there any relation between the bootargs and the bad crc check error ??

Normally you can. There is nothing in  U-Boot  which  would  make  it
specifically dependent on a kernel version; on contrary, we try to be
as generic as possible.

We don't know this kernel tree ... Ask the guys who wrote such a
comment.

We don't know your kernel tree or what it expects.

On the other hand, I've been  using  old  versions  of  U-Boot  (like
0.4.0) with 2.6 kernels without any problems.

We could be more helpful if you provided  more  information,  like  a
*comple*  log  of  your  comands and all output. I speculate that you
don't use a correct U-Boot image at al. What exact command do you use
to build the kernel image, and what are the  last  20...30  lines  of
output of this command?

Best regards,
