Abstract
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...
