METHOD FOR DOWNLOADING FILE USING USB ON BOOTLOADER

摘要

PURPOSE: A method for downloading a file using the USB(Universal Serial Bus) on a bootloader is provided to shorten a file download time by downloading the file needed for a system from an information terminal through the USB. CONSTITUTION: The information terminal constructs a file system to an area of an internal main memory when a download instruction is executed by a host computer(S302). Activating the USB and downloading the file from the host computer connected to the USB, the file is stored in the area of the main memory(S306). The area of a flash memory in the information terminal is removed as much as a capacity of the file copied to the main memory(S310). The file copied to the main memory is stored in the area of the flash memory(S312).
