I crosscompile my kernels because it is much faster... Make sure you download
crosstools
http://www.embeddedarm.com/downloads/Linux/ARM/crosstool-linux-0.28rc39.tar.bz2
. Untar crosstools in the root directory(/). Then download the kernel
source code
http://www.embeddedarm.com/downloads/arm_sbc/linux24-ts9-ksrc.tar.gz. Next
edit the Makefile in the root directory of the kernel source code. Edit the
CROSS_COMPILE environment variable, so that $(CROSS_COMPILE)gcc will point
to your arm-linux-gcc. For instance if you're crosscompiler is in
/usr/local/opt/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2/bin/arm-linux-gcc
the you would set
CROSS_COMPILE = 
/usr/local/opt/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2/bin/arm-linux-

Now you should be able to run make ts7200_config; make oldconfig;
make dep; make vmlinux. Once this process has completed you should see the
file vmlinux.bin in the root directory of the kernel source. You can load
this file via TFTP, HTTP, CF Card... If you load the file via TFTP from
192.168.0.1:/home/eddie/vmlinux.bin you would run the following commands
from redboot.

    RedBoot> load -r -b 0x00218000 -h 192.168.0.1 /home/eddie/vmlinux.bin
    Using default protocol (TFTP)
    Raw file loaded 0x00218000-0x00371487, assumed entry at 0x00218000
    RedBoot> exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"

To load the non-stripped kernel(ie vmlinux), don't use the -r option in the
exec line...
