Abstract

The invention provides a data writing method of embedded equipment. The embedded equipment comprises a processing module and an internal memory module. The processing module comprises a processor and a read-only memory comprising access codes. The method comprises the following steps of: setting the embedded equipment into a writing mode; executing the access codes so as to access an external memory which is connected to the embedded equipment and comprises guide codes; executing the guide codes so as to initialize the embedded equipment; and writing data in the external memory into the internal memory module. According to the data writing method, data can be wrote in by the external memory, such as a safety digital card, a multi-media card and the like without adopting an expensive tool required by traditional recording methods.

Description

technical field [0001] Exemplary embodiments relate to a data writing (burning) method of an embedded device. Background technique [0002] An embedded device, such as a personal digital assistant (PDA), a mobile phone, a portable media player, a digital camera, etc., is a device that implements a predetermined function by running a stored program (eg, an operating system). The difference between embedded devices and ordinary computers (such as personal computers (PCs), laptops (laptops) , Strict requirements on power consumption. Embedded devices generally include processors, memory, input and output (I / O) interfaces, and the like. Generally, a nonvolatile memory such as a flash memory (flash) is used as a memory of an embedded device, for example, a NAND type flash, a NOR type flash, or the like. [0003] Usually, the operating system of the embedded device is written into the memory of the embedded device in the form of a single image file. The image file usually incl...
