S50, the computer re-reads the new EC firmware file in the EC ROM through the EC and executes the starting program;
s60, disconnecting the computer from the external equipment, and finishing the EC firmware updating.
2. The method of claim 1, wherein in step S20, the BIOS interface is a computer-provided user operation interface for configuring and managing computer hardware and boot-up procedures.
3. The method for upgrading EC firmware according to claim 2, wherein a BIOS program is set in the BIOS ROM, and the CPU jumps to a memory address where the BIOS program is located by reading the BIOS program in the BIOS ROM, so as to enter the BIOS interface.
4. An apparatus for upgrading EC firmware applied to the method for upgrading EC firmware as claimed in any one of claims 1 to 3, wherein the apparatus for upgrading EC firmware comprises:
the starting response module is used for establishing connection between the computer and the external equipment; the method comprises the steps that EC acquires a starting signal of a starting button, and a USB controller is connected with external USB equipment in a recognition mode;
The burning module is used for burning the new EC firmware in the external equipment into the EC ROM;
The reading module is used for acquiring new EC firmware in the USB peripheral through connection of the USB controller; the method comprises the steps that the method is used for EC to read original EC firmware and new EC firmware in an EC ROM; the CPU is used for reading BIOS firmware in the BIOS ROM;
The power supply starting and maintaining module is used for starting the power supply module according to the time sequence and maintaining the power supply state;
the state prompting module is used for: and the method is used for prompting whether the new EC firmware is successfully burnt into the EC ROM.
5. A storage medium for use in a computer system comprising a computer program or instructions which, when run on a computer, cause the computer to perform the method of upgrading EC firmware of any of claims 1 to 3.
6. An electronic device comprising a processor coupled to a memory; the processor is configured to execute a computer program stored in the memory, so that the smart terminal performs the method of upgrading EC firmware according to any one of claims 1 to 3.
