Rainbow Electronics QIL-A9260-C11 - Manual (Page 6)

Note: We used the DENX toolchain to built u-boot.You can download this cross-compilation
toolchain from the following adress:
ftp://mirror.switch.ch/mirror/eldk/eldk/3.1.1/arm-linux-x86/iso/arm-2005-03-06.iso
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
