Chip starting method, device, equipment and medium Technical Field The present invention relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, and a medium for starting a chip. Background In the field of chip technology, chip firmware is typically stored in erasable read-only memory (ELECTRICALLY ERASABLE PROGRAMMABLE ROM, EEPROM) or FLASH (FLASH) chips. In order to ensure the stable operation of the chip, a user can write a new firmware program into the EEPROM or FLASH chip by means of a specific refreshing program, so that the firmware upgrading is completed. In order to prevent the chip from being unable to start due to damage of a certain storage medium, the chip usually adopts a dual Flash or dual EEPROM mode to make redundancy backup for the firmware. In the conventional technology, when the chip firmware is updated, new firmware programs need to be written into two Flash or EEPROM. In addition, since most chips are designed to be simplified, they are usually started from a certain Flash or EEPROM, and the starting medium cannot be flexibly specified, which makes another storage medium in an idle state for a long time. Although some chips can be started from a designated medium by means of external pins, in this way, not only is the chip required to draw out additional pins to indicate the starting medium, but also an external circuit is required to record the firmware upgrade state of the chip and input the firmware upgrade state to the chip through the pins, which clearly increases the design complexity and cost of the chip and the external circuit. For this reason, the above technical problems are to be solved by those skilled in the art. Disclosure of Invention In view of the above, the present application aims to provide a method, a device and a medium for starting a chip, which avoid the long-term idle condition of a certain chip medium, improve the utilization rate of the chip medium, simplify the design of the chip and an external circuit, and reduce the design complexity and cost, and the specific scheme is as follows: in a first aspect, the application discloses a chip starting method, which comprises the following steps: Updating starting parameters in target storage areas of all chip media after the chip firmware is updated, wherein the starting parameters in the target storage areas represent the appointed starting states of the corresponding chip media, and the appointed starting states represent whether the corresponding chip media are started or not; after the chip is electrified again, the starting parameters in the target storage areas of all the chip media are read, so that corresponding chip media are selected from all the chip media to serve as starting media based on the read starting parameters, and new firmware programs obtained after the chip firmware is updated are read from the starting media; Executing the new firmware program to realize the chip start.
