[0003] At present, the small core code is often written inside the large core code. The specific download method is to run the download tool to download the large core code to the eMMC, then start the small core download thread mcujlink of the large core chip, read the small core code in the eMMC, and finally download the small core code to the internal and external flash of the small core chip through the JLink port. However, the small core download thread mcujlink needs to be started by manually inputting instructions or automatically matching the version.

[0110] In an embodiment of the present application, a connection between a first system chip and a code cache device is established through a USB virtual serial port, and then a download tool is used to download the first system code in the code cache device to a flash memory module of the first system chip, and the Bootloader program in the first system chip is modified based on the downloaded first system code to obtain a target Bootloader program, and a Jlink interface is simulated in the first system chip based on the target Bootloader program, and a Jlink download path is implemented in the first system chip, so that the second system code in the code cache device can be transferred to the second system chip; during the entire firmware download process, the modified target Bootloader program in the first system chip is used to automatically forward the second system code to the second system chip, and there is no need to trigger the firmware download of the second system chip by manually inputting instructions. In the production system, a workstation dedicated to inputting instructions can be reduced, which not only saves labor costs but also improves production efficiency; there is also no need to trigger the firmware download of the second system chip by automatically matching versions; during the research and development and testing process, the method of automatically triggering the firmware download of the second system chip can avoid firmware download failures due to forgetting to download the firmware of the second system chip or due to power failure, thereby improving the success rate of firmware upgrades.

The storage medium can be a disk, an optical disk, a read-only storage memory, or a random access memory, etc.

[0112] The above disclosure is only the preferred embodiment of the present application, which certainly cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
