Firmware upgrade method and apparatus, and terminal

A firmware upgrade method, wherein the method comprises:

• obtaining an initial differential upgrade package based on difference data of an image of a new firmware version and an image of an old firmware version;
• splitting the image of the new firmware version to obtain a first data block of a first preset length, wherein the first data block is any data block obtained after the image of the new firmware version is split;
• splitting, based on a data area corresponding to the generated first data block in the initial differential upgrade package, the initial differential upgrade package to obtain a second data block, wherein the second data block is any data block obtained after the initial differential upgrade package is split, by:
• determining a field range corresponding to each first data block in the initial differential upgrade package;
• and
• splitting the initial differential upgrade package using an end address of each field range as a splitting point of the initial differential upgrade package;
• determining a dependency of the second data block on each original data block in the image of the old firmware version;
• and
• updating the second data block based on the dependency to obtain a block differential upgrade package, wherein the updating the second data block comprises:
• replacing a part or all of data in the second data block with an operation instruction, wherein the operation instruction is used to instruct to generate, based on the original data block, data that is in the second data block and that is replaced with the operation instruction.

A firmware upgrade apparatus, wherein the apparatus comprises:

• a memory configured to store computer executable instructions;
• and
• a processor, wherein when the processor executes the computer executable instructions, the apparatus is configured to:
• sequentially obtain first upgrade data and operation instructions in all data blocks in a block differential upgrade package, wherein the first upgrade data is data added in an image of a new firmware version in comparison with an image of an old firmware version, and the operation instruction is used to instruct to obtain second upgrade data based on data in the image of the old firmware version;
• determine a field range corresponding to each first data block from among all the data blocks in the block differential upgrade package;
• split the block differential upgrade package using an end address of each field range as a splitting point of the block differential upgrade package;
• convert first data into the second upgrade data in the image of the old firmware version according to the operation instruction, wherein the first data is data in the image of the old firmware version;
• and
• control the first upgrade data and the second upgrade data to overwrite a to-be-upgraded data area in the image of the old firmware version.
