Abstract

A method and apparatus for optimizing the development of an embedded system for a target device. The method may include selecting a set of packages corresponding to the class of an embedded system from various packages available for installation, and integrating the set of packages into a root file system. The method may further include receiving user input identifying at least one application to be used with the embedded system, integrating packages associated with the identified application into the root file system, and loading an image of the root file system to the target device.

accessing, by the tool, a knowledge database that stores information specifying sets of packages for different classes of embedded systems to determine a set of packages for the user-identified class of the embedded system, the information in the knowledge database being collected in view of prior operation of the embedded systems of the different classes;

selecting, from a plurality of packages available for installation, the set of packages for components of the embedded system of the user-identified class, the selecting being performed by the tool based on the knowledge database, without user input identifying domain requirements of the user-identified class of the embedded system;

integrating the set of packages into a root file system;

upon receiving user input identifying at least one application to be used with the embedded system, integrating one or more packages associated with the identified application within the root file system;

identifying, based on the knowledge database, package components to be removed from the root file system in view of the identified application;

modifying the root file system by deleting the identified package components, wherein an image of the modified root file system is to be loaded to the target device; and

in response to determining that operation of the embedded system ends abnormally due to absence of a particular package from the modified root file system, integrating, by a processing device executing the tool, the particular package into the modified root file system, and updating the knowledge database to add the particular package to the set of packages for the user-identified class of the embedded system.

2. The method of claim 1 further wherein integrating the packages associated with the identified application further comprises:

finding a location within the root file system for the packages associated with the identified application.

3. The method of claim 1 wherein integrating the packages associated with the identified application further comprises:

selecting a template file system from a plurality of templates in view of an estimated size of the root file system;

defining a structure of the root file system based on the set of packages and the template file system;

presenting the structure of the root file system to a user; and

requesting the user to specify a location within the root file system for the packages associated with the identified application.

4. The method of claim 1 further comprising:

upon receiving user input indicating one or more parameters for starting execution of the identified application on the target device, generating a script for starting the execution of the application in view of the parameters;

loading the script to the target device; and

testing an operation of the embedded system.

5. The method of claim 1 further comprising:

creating the image of the modified root file system after integrating the particular package into the modified root file system.

6. The method of claim 5 wherein identifying the package components to be removed comprises:

consulting the knowledge database prior to removing package components from the root file system.

7. The method of claim 1 wherein the package components to be removed comprise one or more of unneeded manual pages, unneeded locales, or unneeded device drivers.

8. The method of claim 1 wherein identifying the package components to be removed comprises:

identifying shared libraries that are not referenced by executable files within the root file system.

9. The method of claim 1 wherein the selecting, the integrating of the set of packages, the identifying, the modifying, and the integrating of the particular package are performed without user interaction.

10. The method of claim 1 wherein an operating system of the embedded system is Linux, and the plurality of packages are in an RPM or an IPKG format.

11. A non-transitory machine-accessible medium including data that, when accessed by a processing device, cause the processing device to perform a method comprising:

providing, by a tool running by the processing device on a host computer system, a user interface facilitating user input identifying a class of an embedded system to be developed for a target device, wherein the class of the embedded system comprises one of a set-top box, a network appliance, a handheld device, or a mobile phone;

receiving, via the user interface, a user-identified class of the embedded system to be developed for the target device;

accessing, by the tool, a knowledge database that stores information specifying sets of packages for different classes of embedded systems to determine a set of packages for the user-identified class of the embedded system, the information in the knowledge database being collected in view of prior operation of the embedded systems of the different classes;

selecting, from a plurality of packages available for installation, the set of packages for components of the embedded system of the user-identified class, the selecting being performed by the tool based on the knowledge database, without user input identifying domain requirements of the user-identified class of the embedded system;

integrating the set of packages into a root file system;

upon receiving user input identifying at least one application to be used with the embedded system, integrating one or more packages associated with the identified application within the root file system;

identifying, based on the knowledge database, package components to be removed from the root file system in view of the identified application;

modifying the root file system by deleting the identified package components, wherein an image of the modified root file system is to be loaded to the target device; and

in response to determining that operation of the embedded system ends abnormally due to absence of a particular package from the modified root file system, integrating the particular package into the modified root file system, and updating the knowledge database to add the particular package to the set of packages for the user-identified class of the embedded system.

12. The machine-accessible medium of claim 11 wherein integrating the packages associated with the identified application comprises:

finding a location within the root file system for the packages associated with the identified application.

13. The machine-accessible medium of claim 11 wherein the method further comprises:

testing the execution of the identified application during an operation of the embedded system.

14. The machine-accessible medium of claim 11 wherein the method further comprises:
