The present invention relates to a system and method for providing a development environment for setting and configuring a Linux kernel and an application program constituting an embedded system. More particularly, the present invention relates to a remote development environment using a web service system, and to developers. The present invention relates to a system and method for providing a development environment that can share the results of the system setup and configuration.

Embedded system refers to a system in which a microprocessor, which acts as a brain, is designed in a machine or an electronic device for effective control. In other words, the software that operates the device does not read from disk like a computer, but rather a device embedded in a chip. Currently, mobile phones, portable personal digital assistants (PDAs), digital TVs, and game consoles are representative embedded systems.

These systems have traditionally operated using dedicated programs without operating systems (OSs) or through simple operating systems and applications. However, as modern embedded systems require more and more complex functions, they use the latest technologies rather than simple operating systems. There is an increasing demand for an operating system that can be provided. In particular, these latest technologies are required for TCP / IP communication protocols over the Internet and support for 32-bit high-speed central processing units. This requirement has enabled embedded system developers to adopt the Linux operating system as an economical, easy-to-use embedded operating system. This is because the Linux operating system can be freely changed and distributed under the GNU Public License (GPL) and includes all the features that modern operating systems must have.

 Unlike general personal computers, embedded systems consist of different central processing units, memory, and peripherals. Most embedded systems have a small memory and a central processing unit. Therefore, in order to load Linux into an embedded system, the Linux kernel must be properly configured according to the environment or specifications of the embedded system. In addition, some of the applications to be installed on the target system must be selectively installed, and among various files in the application, the system needs to provide a development environment that can be selectively installed by the user.

In particular, due to the nature of embedded systems, there are many cases in which the Linux kernel and applications depend on each other, which makes setting up the Linux kernel and applications suitable for the target system difficult. In this case, it should be checked in advance during the configuration process to allow the user to configure the Linux kernel and applications together. In other words, it is necessary to configure the Linux kernel and applications, and how the development environment for such integration is provided becomes important.

Due to the nature of the embedded system, it often needs to be developed for a short period of time. Therefore, many developers usually input it and develop it. In addition, embedded systems, which are mainly used in small devices, tend to release several models at the same time. Therefore, the reuse of developed applications and kernel components is considerably high, and thus a method of efficiently sharing them is required.

The existing embedded system configuration tool is installed and operated as an application program on a developer's computer, and the system components developed by each developer are stored in each development environment. Therefore, it is necessary to integrate them, and the process requires cumbersome tasks that require separate version control or output management. Flexibly support the ever-changing needs of embedded systems, and tools that enable multiple developers to effectively share their results contribute to increased productivity and lower development costs.

The method of integrating the Linux kernel and application software package and generating the file list generation method based on CML of Korean Patent Office Publication No. 2004-0055892 filed and filed by Kang Woo-chul and four others is based on the computer language CML2. Integrating and configuring Linux kernel and application software packages, and generating a list of files to be installed on the target computer based on the results of the configuration. In particular, the present invention enables the description of the configurable items of application packages to be installed on the target computer through the option information file, and converts them into CML2 rules files and integrates them with the CML2 rules files of the Linux kernel. Allows integration settings.

The present invention provides a configuration tool for integrating and configuring a Linux kernel and application software package called CML2 language, which is not a method of providing a development environment, but a method of configuration. In order to integrate the CML2 language, the environment for setting the language must be locally configured. As a result, there is a difficulty in the integration process according to the difference in the development environment among the developers. In addition, the setting process has to go through a considerably more complicated process than the easy setting using the web and the result thereof, and the integrated setting result cannot be directly shared with other developers.

In order to solve the above problems in the Linux kernel and application integration configuration process, the present invention provides a separate development environment for each developer remotely using a web-based development server and each developer By sharing the setting result, it is easy to build and manage the development environment and to provide a common R & D environment.

In one embodiment of the web-based development environment providing system according to the present invention for achieving the above technical problem, the development environment providing system for the integrated configuration of the Linux kernel and applications applied to the embedded system is provided by one or more users. A web-based development server to access, an interface unit for receiving integration settings of a Linux kernel and an application program from the connected user, a build unit for performing a build operation according to the input integration settings, and the build job It is configured to include a storage for storing the result of.

In one embodiment of the development environment providing method according to the present invention for achieving the above technical problem, a web-based development environment providing method for the integrated configuration of the Linux kernel and applications applied to the embedded system is a web Authenticating at least one user connected to a development server based on the server; receiving integration settings of the Linux kernel and an application program to configure a system from the access user; creating a kernel image according to the received integration settings And performing an application binary build operation, and storing the result of the build operation on a development server and providing the stored result to the user. When the user wants to share the result of the build task with other users, the result of the build task is shared and stored when the user requests a request for the result of the build task from the other users. Do it.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a diagram showing a setting environment providing system using a development server 101 according to an embodiment of the present invention.

Referring to FIG. 1, the development server provides various interfaces to a developer 107 who is a largely connected user and receives various types of information, an interface unit 104 for receiving information, a build unit 106 for performing a build operation of a setting, and a build. It is composed of a storage unit 102 for storing the results of the work. The developer 107 is connected to the service providing unit 105 of the development server by using a web browser, it is possible to store the work results 103 in the storage unit 102 on the server. The stored results 103 can be shared with other developers according to the developer's settings. It will be described below unified as a general user.

The system builds a central development server and provides the developer with a development environment on the central server under the web interface to compose the development environment without any additional installation work. It has a feature in organizers that can be shared with developers.

2 is a diagram illustrating a method for providing a development environment according to a data flow between a user connected to a development server according to an exemplary embodiment of the present invention.

Referring to FIG. 2, a user accesses a development server 202 waiting for a service 201 using a web browser 203. The development server authenticates the connected user as one user (204). For the request of the wizard page for the user's system setting (205), the development server executes the project wizard service (206). An interface for creating a project and setting up a system through a web page is provided (208), and a user performs various system setting work through a web browser (207). The kernel image and the application binary build work according to the configuration are performed in the build unit (210), and the completed result is also stored in the server (212). The user can monitor progress and control the build during the build (209). The communication between the server and the user is asynchronous communication using Ajax (215). The user can download the result image of the build operation (211), and can be set to share with other user groups (213, 214). Afterwards, if the user wants to receive the result shared by the user at the wizard page request step (205), the server shows the shared project list so that the other user can receive the project with the shared setting (206) (216).

Traditional web applications fill out a form, submit it, and send a request to the web server. The web server returns the output to a new web page based on the content sent. However, this approach makes it more difficult to create highly interactive user interfaces than native applications. Accordingly, in the present invention, Ajax (Asynchronous Javascript and XML) enables build status monitoring and control to be at the native application level (215).

Referring to FIG. 3, the development server authenticates a connection from a user (S301) and provides a wizard page for a user's integration setting process (S302). At this time, if the connected user has a request for the work results already shared for setting (S303), the server provides the shared work results (S304). If the user integration setting process (S305) is performed, the server performs a build operation according to the setting details (S306). After the build operation, the result is stored in the server and provided to the user (S307). According to the user's intention (S308), the server allows to set the result of the build operation (S309).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, which are also implemented in the form of a carrier wave (for example, transmission over the Internet). It also includes. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
