You can download the Linux Kernel Sources from our anonymous
git server at http://git.denx.de/.
To checkout the module for the first time, proceed as follows:
bash$ cd /opt/eldk/usr/src
bash$ git clone git://git.denx.de/linux-2.6-denx.git linux-2.6-denx
bash$ cd linux-2.6-denx
bash$ git checkout -b duts remotes/origin/44x/canyonlands
Branch duts set up to track remote branch 44x/canyonlands from origin.
Switched to a new branch 'duts'
bash$
The canyonlands 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 "powerpc" 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 canyonlands
board that has been extensively tested. It is recommended to use this
as a starting point for other, customized configurations:
bash$ make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- 44x/canyonlands_defconfig
Note: The name of this default configuration file is arch/powerpc/configs/44x/canyonlands_defconfig
. By (recursively) listing the contents of the arch/powerpc/configs/
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=powerpc CROSS_COMPILE=ppc_4xxFP- uImage
Otherwise you can modify the kernel configuration as follows:
bash$ make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- config
or
bash$ make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- menuconfig
Note: Because of problems (especially with some older Linux kernel
versions) the use of "make xconfig" is
not recommended.
bash$ make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- uImage
The make target uImage uses
the tool mkimage (from the U-Boot package) to
create a Linux kernel image in
arch/powerpc/boot/uImage
which is immediately
usable for download and booting with U-Boot.
In case you need a DTB to boot your linux kernel, you need the following
step:
bash$ make canyonlands.dtb
In case you configured modules you will also need to compile the modules:
make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- modules
add install the modules (make sure to pass the correct root path for module installation):
bash$ make ARCH=powerpc CROSS_COMPILE=ppc_4xxFP- INSTALL_MOD_PATH=/opt/eldk-4.2/ppc_4xx modules_install
For now it is sufficient to copy the Linux kernel image into the
directory used by your TFTP server:
bash$ cp arch/powerpc/boot/uImage /tftpboot/uImage
