WARNING: BACKUP YOUR DATA FIRST

Prerequisites

RHEL/Fedora/CentOS: 

yum install ncurses-devel ncurses
yum groupinstall "Development Tools" "Development Libraries"

Ubuntu/Debian:
apt-get install build-essential libncurses5-dev libncursesw5-dev

For other distributions, please refer to their documentation to find equivalent tools.

Set up the Sources and Toolchain 

wget ftp://ftp.embeddedTS.com/ts-arm-sbc/ts-7200-linux/cross-toolchains/crosstool-linux-gcc-3.3.4-glibc-2.3.2-0.28rc39.tar.bz2

wget ftp://ftp.embeddedTS.com/ts-arm-sbc/ts-7200-linux/sources/tskernel-2.4.26-ts11-feb232011.tar.gz

tar -xvzf tskernel-2.4.26-ts11-feb232011.tar.gz

cd linux24

Open the Makefile and edit CROSS_COMPILE to say: 

 CROSS_COMPILE = insert/your/directory/structure/here/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2/bin/arm-linux-

Next the config file needs to be set up. Run "make menuconfig"

  • Load the TS-7200 config file by typing "L" three times, "ENTER", and specify "arch/arm/def-configs/ts7200". When finished, save and exit back to the menuconfig
  • Exit menuconfig and be sure to say "Yes" to save any changes
make dep
make Image
make zImage

The kernel will be present at "arch/arm/boot/Image" or "arch/arm/boot/zImage" for the compressed version.

Note: Large kernels may not fit in the kernel partition of the boot device. Check the size of the newly created kernel and ensure it will fit before writing to disk.

The modules can then be installed to a local directory and packed in to an archive to unpack on the SBC: 

make modules
INSTALL_MOD_PATH="`pwd`/newmodules" make modules_install
tar czvf modules_2.4.26-ts11.tar.gz -C newmodules/ .

Copy the modules tarball archive to a USB drive or other accessible media (FTP, NFS, etc.), then unpack the archive to the root folder of the device. See the redboot instructions for loading a kernel permanently on devices that use RedBoot.

Note: Once installed to the target filesystem, "depmod" should be invoked manually to update the module loading and dependency list.
