<p>Provided are a firmware upgrade method, apparatus and device, and a mobile terminal. The firmware upgrade method comprises: acquiring an upgrade start command; after the upgrade start command is acquired, reading a firmware upgrade file from a secure digital memory; and writing the firmware upgrade file into a Flash memory. When an SD interface does not support an SDIO function, the mobile terminal and the communication device of the SD interface can only read and write data in the secure digital memory in units of files. In the present application, special files are defined in the secure digital memory, and are used for storing the upgrade start command and upgrade data into different files, so as to enable the mobile terminal and the communication device of the SD interface to learn whether the data stored in the files is a upgrade start command or upgrade data by recognizing file names, so that the communication device of the SD interface can acquire the upgrade start command from a command exchange file, and acquire a firmware upgrade file during the firmware upgrade to perform the upgrade.</p> |
