Provided is to an apparatus for application testing of an embedded system which can cross-develop an application program installed in the embedded system regardless of the type of a target system. A virtual environment for testing the application program adopted in the target system is constructed on the basis of information inputted through a user interface and the application program is tested by configuring a virtual target system in the constructed virtual environment. According to the present invention, the application program adopted in the target system can be developed and tested without constructing a cross-development environment for each target system in an environment in which various kinds of embedded systems are developed.

A method for binarizing initial script on an operating system includes: calling shell script to be binarized in a secondary memory unit; generating an execution table by translating the called shell script; generating a source program by merging a previously prepared source code template with the execution table; and combining a command sub-routine with the source program and binarizing the shell script by performing compile and building operations. According to the above, it is possible to minimize a booting delay time without using a fork & exec technique by applying the binary script instead of the shell script during performing system initialization while booting.

Disclosed is a flash memory device having a secure flash file deletion function and a method for securely deleting a flash file. Data and object headers as actual contents of the flash file are separately stored in data blocks and header blocks. At this time, the data is encrypted and stored, and a decryption key is included in an object header and stored in a header block. When the flash file is deleted, the object header is deleted by searching the header block where the object header including the decryption key is stored. In order to search the header block, a binary tree structure is used in which a terminal node indicates an LSB of a file ID. Disclosed may be applied to an embedded system where a flash memory is used as a storage medium. In particular, disclosed is suitable for a NAND flash memory device.
