Figure 4: Software System Structure

The features and functions of each part of the system are:

1. x-loader is a first level bootstrap program. After the system

start-up, the ROM inside the CPU will copy the x-loader to

internal RAM and perform work. Its main function is to initialize

the CPU, copy u-boot into the memory and give the control power

to u-boot;

2. u-boot is a second level bootstrap program. It is used for

interacting with users and updating images and leading the

kernel;

3. The latest 2.6.32.x kernel is employed and can be customized

based on the SOC8200;
