Embodiment 1

[0040] Such as Figure 1 ~ Figure 2 As shown, the multi-chip firmware program update method provided by the embodiment of the present invention includes the following steps:

[0041] Step A, storing the firmware programs of more than two chips 4 to be upgraded in a firmware storage device 3;

[0042] Step B, upgrade the firmware program corresponding to the part (can be one) or all of the chips 4 to be upgraded stored in the firmware storage device 3;

[0043] Step C, the chip 4 to be upgraded obtains its own upgraded firmware program from the firmware storage device 3 , and uses the upgraded firmware program to update its existing firmware program or execute the upgraded firmware program.

[0044] Because the firmware program of more than two chips 4 to be upgraded can be stored in a firmware storage device 3 provided by the present invention, it is only necessary to upgrade the firmware program stored in one firmware storage device 3, and then allow more than two chips 4 to...

Embodiment 2

[0050] Such as figure 1 with image 3 As shown, this embodiment is basically the same as the method embodiment 1, the difference is that: in step C of this embodiment, the chip 4 to be upgraded actively obtains it from the firmware storage device 3 through different addresses. At this time, different chips 4 to be upgraded can also realize that they do not affect each other during the upgrading process. In this embodiment, the chip 4 to be upgraded actively loads the firmware program from the firmware storage device 3 .

[0051] As an optional embodiment, the chip 4 to be upgraded is an MCU, and the firmware storage device 3 is an external memory. Multiple MCUs are connected to a memory chip (such as flash), and all firmware is stored on this memory chip, and each MCU obtains and executes its own firmware program through different addresses; in this way, only one total memory file needs to be upgraded when upgrading the firmware.

[0052] Such as figure 2 with image 3 A...

Abstract

The invention discloses a multi-chip firmware program updating method and a multi-chip firmware program updating system, relates to the technical field of chips, and solves the technical problems of complex updating operation, and time and labor waste in the prior art. The multi-chip firmware program updating method comprises the steps of storing firmware programs of two or more to-be-upgraded chips in a firmware storage apparatus; upgrading the firmware programs corresponding to part or all of the to-be-upgraded chips stored in the firmware storage apparatus; and obtaining the respective upgraded firmware programs from the firmware storage apparatus by the to-be-upgraded chips, and updating the existing firmware programs by utilizing the upgraded firmware programs or executing the upgraded firmware programs. The multi-chip firmware program updating system comprises a loading module, an upgrading module, the firmware storage apparatus and the two or more to-be-upgraded chips. The method and the system are used for simplifying the steps of the updating operation and reducing time consumption of the updating operation.

Description

technical field [0001] The invention relates to the field of chip technology, in particular to a multi-chip firmware program update method and a multi-chip firmware program update system. Background technique [0002] As electronic products such as mobile phones become more and more complex, there are more and more situations in which multiple MCUs (Microcontroller Units, micro control units) are used in one product. Existing OTA (Over-the-Air Technology, over-the-air technology) can only update the firmware program of one MCU at a time. When there are multiple MCUs in an electronic product, the firmware program of each MCU needs to be updated one by one. [0003] The applicant found that: the prior art has at least the following technical problems: [0004] In the prior art, when there are multiple MCUs in an electronic product, the firmware program of each MCU is updated one by one. The update operation is complicated, time-consuming and laborious, which seriously affects...
