The invention discloses an embedded device startup Logo updating and displaying method and system, and the method comprises the steps: reading a picture file stored in a USB storage device, carrying out the analysis of the picture file through the embedded application layer software, enabling the picture file to be written into a Logo description file, and enabling the picture file to be stored ina Boot partition; enabling the Boot Loader to load the Logo description file of the Boot partition to a specific address interval, protected by the kernel, of the memory before loading the kernel; And after the kernel is started, analyzing the Logo description file loaded into the memory, and writing the analyzed data into the FrameBuffer to realize Logo display. That is to say, Logo updating canbe carried out on the embedded device only through one USB storage device, and a user can directly replace the Logo updating device. Meanwhile, the Logo-related file can be generated in the application software of the embedded device, a specific Logo-related file does not need to be generated on computer software, and the Linux kernel does not need to be recompiled.
