4.5 Linux System Deveplopment

This section will introduce how to establish a Linux system development

platform to run on the SOC8200 hardware platform with the use of the

SOC8200 BSP. Details to be provided contain the formation of a cross

compilation environment, the generation of a system image and a

demonstration of how to customize the system.

For the SD card, after formatting and dividing into FAT and EXT3 under an

ubuntu system, the FAT partition needs reformatting under a windows

system, otherwise, start-up with SD card can not be done.

4.5.1 Install the cross compilation environment

The user must form an arm Linux cross compilation environment before

developing for the SOC8200. We will use the ubuntu operating system as an

example to introduce the formation of a cross compilation environment. The

operation in Linux is similar with that in ubuntu system.

Insert the CD, ubuntu will mount the CD under the /media/cdrom directory,

and the cross compilation tool will be put under the

/media/cdrom/linux/tools directory.

Users can execute the following commands to start up the installation of the

cross compilation tool:

cd /media/cdrom/linux/tools

tar xvjf arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 -C

/home/embest

Note:

 This manual uses /home/embest as the default installation directory. This can

be changed if required.

4.5.2 The installation of other tools

Other tools included in linux/tools directory of the CD may be used for

source code. Users can execute the following commands for installation:

mkdir /home/embest/tools

cp /media/cdrom/linux/tools/mkimage /home/embest/tools

cp /media/cdrom/linux/tools/signGP /home/embest/tools
