Method for Running Startup Program of Electronic Device, and Electronic Device

A method for upgrading a boot program of an electronic device, wherein the electronic device comprises a processor, a first storage, and a second storage, the first storage is a read-only memory from which the processor can directly read data, and the second storage is a secondary storage from which the processor reads data by using a memory;

• and the method comprises:
• obtaining, by the processor, an upgrade package of the boot program, wherein a first program block corresponding to a first part of the boot program is stored in the first storage, and the first program block is used to implement security authentication before the boot program is run;
• selecting, by the processor, one of a second program block and a third program block as a target program block to be upgraded, wherein the second program block is stored in the first storage, the third program block is stored in the second storage, and both the second program block and the third program block belong to a second part of the boot program, and are configured to run the boot program;
• and
• upgrading, by the processor, the target program block based on the upgrade package of the boot program.

An electronic device comprising:

• a processor, a first storage, and a second storage, wherein
• the first storage is a read-only memory from which the processor can directly read data, the first storage stores is configured to store a first program block and a second program block, the first program block belongs to a first part of a boot program and is configured to implement security authentication before the boot program is run, and the second program block belongs to a second part of the boot program and is configured to run the boot program;
• wherein the second storage is a secondary storage from which the processor is to data by using a memory, the second storage stores a third data block, and the third program block belongs to a second part of the boot program and is configured to run the boot program;
• wherein the processor is configured to obtain the first program from the first storage, and run the first program block to implement security authentication before the boot program is run;
• wherein the processor is further configured to select one of the second program block and the third program block as a target program block in a later operation;
• and
• wherein in response to running of the first program block being complete, the processor is further configured to run the target program block to run the boot program.
