Building S3C6410 embedded Linux platform

    VMWare is a virtual PC software. VMWare's products allow you to run two or more Windows, DOS, and LINUX systems on one machine at the same time. Compared with the "multi-boot" system, VMWare adopts a completely different concept. The multi-boot system can only run one system at a time, and the machine needs to be restarted when the system is switched. VMWare is truly "simultaneous" running, with multiple operating systems on the platform of the main system, just like standard Windows applications. Moreover, you can perform virtual partitions and configurations on each operating system without affecting the data on the real hard disk. You can even connect several virtual machines to a local area network through a network card, which is extremely convenient. The performance of the operating system installed in VMware is much lower than that of the system directly installed on the hard disk. Therefore, it is more suitable for learning and testing.

   We use: vmware 7.0.1.exe

2. Install Ubuntu

   Ubuntu is a Linux operating system that is mainly used for desktop applications. Ubuntu has many advantages. Compared with other versions of Linux, Ubuntu also has its own advantages. First, the installation system is very simple and only requires very few settings, which is completely comparable to the Windows desktop system; second, the graphical interface is very user-friendly, imitating the shortcut keys commonly used in XP; and when installing and upgrading programs, the system can install the dependent file packages through the network, so you don't have to worry about the dependencies of the Linux system. Considering everyone's usage habits and learning needs, we chose Ubuntu Linux.

  We use the Ubuntu9.10 CD image 'ubuntu-9.10-desktop-i386.iso' to install
  Ubuntu. The official website: http://www.ubuntu.org.cn
   can download various versions of Ubuntu. Of course, the official website can find all kinds of information about Ubuntu. The
   Ubuntu official forum: http://forum.ubuntu.org.cn/
    can find a lot of practical Ubuntu resources, Chinese forums. Ubuntu also has an official English forum.

3. Set Ubuntu to automatically log in as the root user
Embedded cross-compilation often requires root user privileges. Change the default user of the terminal after logging in to root.
If similar privilege issues occur during the compilation process, be sure to check the current user privileges.
� Create a new terminal in Ubuntu (click here to view the method for creating a new terminal), and enter:
#sudo –s
#sudo passwd
Enter the password to be set, so that we can log in as the root user in the future.
� Enter in the terminal:
#sudo gedit /etc/gdm/custom.conf
A text editor will pop up at this time, modify the content of 'custom.conf' to the following content (if the original file is empty,
enter these contents), save and close, restart Ubuntu, and you will find that you have automatically logged in as the root user.
[daemon]
TimedLoginEnable=true
AutomaticLoginEnable=true
TimedLogin=root
AutomaticLogin=root
TimedLoginDelay=30

4. Install the cross compiler
Copy the arm-linux-gcc-4.3.2.tgz file to the /forlinx directory of Ubuntu. The file is located in
the "Utilities" folder of the User Basics CD. Create a new terminal in Ubuntu and enter the following command to install the cross
compiler:
#cd /forlinx (enter the /forlinx directory)
#mkdir /usr/local/arm (create a directory, if the directory already exists, an error will be prompted, just skip it)
#tar zxvf arm-linux-gcc-4.3.2.tgz -C /
(unzip the compiler to /usr/local/arm)

After completion, the "4.3.2" directory will be generated in the /usr/local/arm/ directory.

In this way, the kernel or other applications all use /usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-gcc
to specify the use of the cross compiler.

For example, to check the version of this compiler, we can run
#/usr/local/arm/4.3.2/bin/arm-none-linux-gnueabi-gcc -v. If
the compiler is installed correctly, the compiler version and other information will be displayed.
