A CPLD-based remote upgrade control method, comprising: receiving a file to be loaded which is sent by a remote control platform, the file to be loaded comprising a file content and an attached check code, and the attached check code being generated uniquely after checking the file content of the file to be loaded according to a conventional algorithm; rechecking the received file to be loaded in accordance with the conventional algorithm so as to generate a new unique check code, and comparing the newly generated check code with the attached check code; and if it is detected that the newly generated check code is the same as the attached check code, loading the file to be loaded to a CPLD. Also disclosed is a CPLD-based remote upgrade control apparatus. By means of the embodiments of the present invention, before a file is loaded, an error of the file to be loaded during the transmission is discovered in time, so that the reliability of remote upgrade of the CPLD can be ensured, the normal operation of the entire system can be maintained, and the damage of an electronic device can be avoided. |
