Embedded Linux Platform Setup

Choose Ubuntu12.04.2 System to build the platform. Make the following changes under the original system:

1. Set the server used by the update to a domestic "163" server
2. Installing software such as Ssh,uboot-mkimage
3. Installing the Compiler "ARM-2009Q3" and related library files
4. Run the scripts in the JDK to install the JDK
5. installing compiler arm-linux-4.4.3 and related library files

1. Click Settings->software&updates in the Ubuntu GUI and select Http://mirrors.163.com/ubuntu from the dropdown menu in the Download form bar.

2. Installing Mkimage Tools

Execute the Make Uimage command under the shell, and if the Mkimage tool is not installed on the system, the following error message appears:

"Mkimage" command not found-u-boot images won't be built

The reason is that the Mkimage tool is not installed in the system.

Workaround: Install the Mkimage tool and execute the following command to install it:

#sudo Apt-get Install Uboot-mkimage

Compile the Uboot source code, after the successful compilation in the Uboot/tools directory will generate Mkimgage tools, mkimage tools to copy to the/usr/bin/directory.

3. Install the compiler arm-2009q3

3.1. Visit the Codesourcery official website to download the latest arm cross-compiler toolchain, currently the latest version is arm-2009q3:
http://www.codesourcery.com/sgpp/lite/arm/portal/package5383/public/arm-none-linux-gnueabi/ ARM-2009Q3-67-ARM-NONE-LINUX-GNUEABI-I686-PC-LINUX-GNU.TAR.BZ2 3.2. Unzip
$ TAR-JXVF arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 3.3. Move to/usr below MV Arm -2009q3/usr/3.4. Setting environment variables $ sudo su # VIM/ETC/BASH.BASHRC in the last add On
Export path= $PATH:/usr/arm-2009q3/bin
Export PATH startup environment variable setting: #source/ROOT/.BASHRC to check if the setting is successful: #e Cho $PATH results:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/arm-2009q3/bin
The instructions are set up well. 3.5. Check if the installation was successful: $ arm-none-linux-gnueabi-gcc-v ==> Using built -in specs.
Target:arm-none-linux-gnueabi
...
GCC version 4.4.1 (sourcery g++ Lite 2009q3-67)
Indicates that the installation was successful. 3.6 If the installation is complete, but an error occurred while viewing the compiler version

5. Install compiler arm-linux-4.4.1 and related library files

          Download arm-linux-gcc-4.4.3.tar.gz

5.1. Create a directory

$ sudo mkdir/usr/local/arm

5.2. Copying files

File arm-linux-gcc-4.4.3.tar.gz, put in the desktop

Go to Desktop

$ CD ~/desktop

$ sudo cp arm-linux-gcc-4.4.3.tar.gz/usr/local/arm

$ cd/usr/local/arm

$ sudo tar-xzvf arm-linux-gcc-4.4.3.tar.gz

5.4. Add Environment variables

Open the file with Gedit BASH.BASHRC

$ sudo gedit/etc/bash.bashrc

Add "Export Path=/usr/local/arm/opt/friendlyarm/toolschain/4.4.3/bin: $PATH" on the last line to save the file

5.5. Registering Environment variables

Run/ETC/BASH.BASHRC

$ . /etc/bash.bashrc

5.6. Whether the test is successful

View the version number, if any, to succeed

$ arm-linux-gcc-v

5.7 If not successful

No such file or directory
