[Abstract]:With the promotion of information technology in various industries, the computing power, complexity and application scope of embedded systems are developing rapidly. However, the research and development of embedded systems involve a wide range of knowledge, comprehensive and practical.The rapid development of disciplines requires more hardware devices, complex development platforms and related tools, and low abstraction of the development environment and tools, which results in the cost and cycle of embedded research and development and education greatly affected.In recent years, 32-bit RISC processors have gradually become the mainstream of the embedded field. Open source software has developed rapidly and has been widely used in embedded systems.Embedded Linux occupies the top position in market share and has a rising trend. E-Learning has been widely accepted as a new, efficient and free teaching mode in various disciplines.These factors make it possible to build an online embedded development platform for embedded R & D and education.Based on the research work of embedded real-time system during the author's master's study, this paper focuses on the design and development of an online development platform for embedded software based on open source software, based on the analysis of the existing embedded development platform.The platform abstracts embedded devices and development processes at different levels, and then unifies the management of various development boards, virtual development machines and auxiliary development equipment, and integrates the editing, compiling, debugging and other software of the software IDE, through various software, interfaces, etc.The tool and control system realize the remote access ability of the equipment, develop the corresponding core function module and graphical user interface, realize a multi-platform-oriented, integrated, personalized and open,Online Embedded Laboratoryis a convenient embedded online development platform, hereinafter referred to as OELabA.OELab supports WEB and two graphical user interfaces based on PyGTK and X11. Now it supports Windows and Linux platform. OELab integrated development environment includes all the tools needed for embedded software development, provides console access, power management, code download, etc.Remote operating interfaces such as video surveillance and initial state recovery greatly facilitate embedded developers and improve development efficiency. The development can not be limited by time and place, and promote device sharing, information exchange and remote collaboration.For embedded learners, ELab can save most of the cost of purchasing embedded development equipment and get the same or better operation experience at the same time. Experimental learning through OELab can effectively shorten the learning cycle and has a better teaching effect.In addition, the initial state recovery function of the system makes it unnecessary for the user to misoperate the target board.Based on the requirements of OELab framework and laboratory in real-time system, the author developed a test platform for embedded system, aiming at the performance of embedded real-time system for a long time.Comprehensive testing provides data for system evaluation and guidance for system optimization.The test is automatically controlled by the script, and the result is rendered to the user automatically by the script program.At the end of this paper, the author summarizes and looks forward to some aspects that need improvement on the basis of analyzing the advantages of OELab, which can be used as a guide for future work.
