Note: We used the DENX toolchain to built u-boot.You can download this cross-compilation

toolchain from the following adress:

1.3. Linux Kernel

The linux kernel will be setup and built in the usual way.

First we 'll configure the kernel with the default configuration files.

There are 2 configuration files for the kernel:

● qil-a9260_jffs2_defconfig

● qil-a9260_cpio_defconfig

The first configuration file allows to built a kernel which mount the root file system from the

first nand flash partition (/dev/mtd1). The second one allows to built a kernel bound to a root

file system (cpio archive).

Here are the steps needed to compile the linux kernel.

● cd LINUX_KERNEL_V2.6.21/

● make qil-a9260_jffs2_defconfig or qil-a9260_cpio_defconfig

If you want to change the linux kernel configuration issue the following command:

● make menuconfig

Once configured and saved, edit the makefile and specify the name of your cross-compiler.

Then issue the make command to built the kernel

● make uImage
