You can download the Linux Kernel Sources from our anonymous CVS server at
http://www.denx.de. To checkout the module for the first time, proceed
as follows:
bash$ cd /opt/eldk/usr/src
bash$ cvs -d :pserver:anonymous@www.denx.de:/cvsroot login
[Press return when asked for a password]
bash$ cvs -z6 -d :pserver:anonymous@www.denx.de:/cvsroot co -P foo
bash$ cd foo
You can download the Linux Kernel Sources from our anonymous
git server at
http://www.denx.de/cgi-bin/gitweb.cgi.
To checkout the module for the first time, proceed as follows:
bash$ cd /opt/eldk/usr/src
bash$ cg-clone http://www.denx.net/git/linux-2.6.git linux-2.6
bash$ cd linux-2.6

The %BOARDNAME% board is fully supported by DENX Software Engineering.
This means that you will always be able to build a working default
configuration with just minimal interaction.
Please be aware that you will need the ppc cross development
tools for the following steps. Make sure that the directory which
contains the binaries of your
ELDK? are in your
PATH.
To be sure that no intermediate results of previous builds are left
in your Linux kernel source tree you can clean it up as follows:
bash$ make mrproper
The following command selects a standard configuration for the %BOARDNAME%
board that has been extensively tested. It is recommended to use this
as a starting point for other, customized configurations:
bash$ make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% %BOARD%_defconfig
Note: Included topic
DULGData.BOARDLinuxConfig? does not exist yet
Note: The name of this default configuration file is . By listing the contents of the directory you can easily find out which other default configurations are available.
If you don't want to change the default configuration you can now
continue to use it to build a kernel image:
bash$ make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% uImage
Otherwise you can modify the kernel configuration as follows:
bash$ make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% config
or
bash$ make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% menuconfig
Note: Because of problems (especially with some older Linux kernel
versions) the use of "
make xconfig" is
not recommended.
The
make target
uImage uses
the tool
mkimage (from the U-Boot package) to
create a Linux kernel image in
which is immediately
usable for download and booting with U-Boot.
In case you configured modules you will also need to compile the modules:
make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% modules
add install the modules (make sure to pass the correct root path for module installation):
bash$ make ARCH=%ARCH% CROSS_COMPILE=%CROSS_COMPILE% INSTALL_MOD_PATH=%ROOTPATH% modules_install

For now it is sufficient to copy the Linux kernel image into the
directory used by your TFTP server:
