Porting means making something work on an environment it is not designed for. Embedded Linux porting means making Linux work on an embedded platform, for which it was not designed. Porting is a broader term and when I say embedded Linux porting, it not only involves Linux kernel porting, but also porting a first stage bootloader, a second stage bootloader and, last but not the least, the applications. Porting differs from development.

Bootloader code customization, U-Boot
U-Boot Image for Target Board
CH4: Kernel Configuration : : Linux kernel Cross Compilation
Download the kernel source code linux-xx.yy.zz.tar.bz2untar it with 'tar -jxvf linux-xx.yy.zz.tar.bz2
Copy the new config as .config in kernel top level directory
Update the the config file using make ARCH=arm menuconfig
Compile the kernel with make ARCH=arm CROSS_COMPILE=
Generating Kernel Image uImage or zImage, dtb
Transfer this is to the Target Board and reboot to boot with new kernel image using tftp or nfs
Application development and Cross Compilation
CH5: Porting Linux kernel,U-boot images on Target board
Sd Card partitioning and FormattingWrtting uImage,U-boot.bin into Sd cards
Extract and copy rootfs in SD-Card rootfs partition
Configuring NFS and using rootfs over NFS
Building the Embedded Board Using NFS
CH6: Building the Device driver as a part of Kernel(in kernel tree)
We will add a Device driver to the kernelCopy the file driver.c to linux-xx.yy.zz/drivers/char/
Edit the Kconfig file in drivers/char/
Edit the makefile and add obj-$(CONFIG_MY_DRIVER) += driver.o
Configure the kernel with make ARCH=arm menuconfig
Now, compile the kernel with make ARCH=arm CROSS_COMPILE=
Test the driver, with application Program
