I. C language

C language is the main programming language in embedded field. Focus on understanding the basic programming and advanced programming knowledge of C language, including: basic data types, arrays, pointers, structures, linked lists, file operations, queues, stacks and so on.

II. Linux Foundation

Detailed understanding of Linux directory structure, basic commands, editor VI, compiler GCC, debugger GDB and Make project management tools, Shell Makefile scripting and other knowledge, as well as the construction of embedded development environment.

III. Linux system programming

Focus on learning the standard isign O library, multiprocess and multithreading in Linux multitasking programming, as well as inter-process communication (pipe, FIFO, message queue, shared memory, signal, semaphore, etc.), synchronization and mutual exclusion of shared resources access control and other important knowledge, mainly to improve the understanding of Linux application development and the ability of code debugging.

IV. Linux network programming

Focus on learning API related to network programming, skillfully master the programming method of TCP protocol server and the implementation of concurrent server, understand HTTP protocol and its implementation method, be familiar with the principle and programming method of UDP broadcast and multicast, master the design of mixed Cmax S architecture network communication system, and be familiar with Web programming techniques and implementation methods such as HTML and Java.

5. Data structure and algorithm

The focus of this stage of learning is to understand the basic contents of data structures and algorithms, including sequential lists, linked lists, queues, stacks, trees, graphs, hash tables, various search and sorting algorithms and their C language implementation.

6. C++ and QT

This stage focuses on mastering the basic ideas of object-oriented programming and the important contents of C++. Graphical interface programming is a very important link in embedded development. Because QT has powerful functions such as cross-platform, object-oriented, rich API, supporting 2D/3D rendering, supporting XML, multi-language and so on, it has been widely used in embedded GUI development. At this stage, students can skillfully write GUI programs through learning based on QT graphics library, and transplant QT applications to Cortex-A8 platform. It includes the use of IDE, QT components and layout manager, the application of information and slot mechanism, mouse, keyboard and drawing event processing and file processing applications.

VII. Development of Cortex A8 and Linux platform

Based on ARM Cortex-A8 processing s5pv210 to understand the basic reading skills of chip manual, master s5pv210 system resources, clock controller, power management, abnormal interrupt controller, nand flash controller and other modules, to prepare for the construction of the underlying platform.

The Linux platform includes kernel reduction, kernel transplantation, cross-compilation, use of GNU tools, kernel debugging, Bootloader introduction, production and principle analysis, root file system creation and adding its own modules to the kernel. The Linux system made by ourselves is run on the s5pv210 experimental platform, and the whole process of deploying Linux system is integrated. At the same time, understand the Android operating system development process.

VIII. Driver development

In this stage of study, we should be familiar with the kernel mechanism of Linux, the interface between drivers and user-level applications, and master the concurrent operation of the system to the device. Familiar with the working principle of the developed hardware, basic knowledge of ARM hardware interface, familiar with ARM Cortex-A8 processor s5pv210 resources, master Linux device driver principle framework, familiar with engineering Linux advanced character equipment, block equipment, network equipment, USB equipment and other driver development, can independently be competent for underlying driver development.
