Linux BSP User Guide for AM335x series

Start Guide

Generally，to do Linux development, you’ll need a host PC running Linux. In the development with the advantech SDK, it would be strongly recommend to use Ubuntu 12.04 LTS 64 bit/ Ubuntu 14.04 LTS 64 bit as developing environment. Because we have successfully tested our BSP on these OS version. Please install the Ubuntu 12.04 LTS 64 bit / Ubuntu 14.04 LTS 64 bit at your PC/NB in advance.

Configure your Linux Host

Please refer to Configure your Linux Host to configure  your linux host.

BSP Building Guide

In the following building demo, we always assume building is for RSB4220 platform. others(such as ROM3310,RSB4221) are same。 $(BSP) is your BSP root directory. In order to simplify the description， we use "$(BSP)" to represent actual BSP root path. you need to replace the string to actual path。

1. Setup uboot and kernel build environment

• $ sudo su (Change to “root” authority)
• Input user password
  1. cd $(BSP)/scripts/
  2. source setenv.sh (To configure the developing environment automatically)

Then you can start to code the source code, build uboot and kernel images.

The setenv.sh script is used to configure the developing environment quickly. It will configure the folder paths for system.

Note! You have to run “#source setenv.sh” every time once you open a new "Terminal" utility. It is suggested to change to “root” authority to use the source code. And the “$(BSP)” is the root directory of BSP source code.
2. Build u-boot Image
Advantech has a script to build the u-boot quickly. You can build u-boot image by follow below steps:

• Open "Terminal" on Ubuntu host PC.
• $sudo su (Change to “root” authority)
• Input user password.
  1. cd $(BSP)/scripts/
  2. source setenv.sh (To configure the developing environment automatically)
  3. ./cfg_uboot.sh am335x_rsb4220_defconfig (To set the u-boot configuration automatically)
  4. ./mk_uboot.sh (Start to build the u-boot)

Then you can see u-boot.img is being built and located in ../image.

3. Build Linux Kernel Image
Advantech offer you a script to build the “uImage” quickly. You can build uImage by follow below steps:

• Open "Terminal" on Ubuntu host PC.
• $sudo su (Change to “root” authority)
• Input user password.
  1. cd $(BSP)/scripts/
  2. source setenv.sh (To configure the developing environment automatically)
  3. ./cfg_kernel.sh tisdk_am335x‐rsb4220_defconfig (To set the uImage configuration automatically)
  4. ./mk_kernel.sh (Start to build the uImage)

Then you can see uImage is being built and located in ../image.
