The second button and the third button are respectively connected to the main 1860 chip; the power-on detection configuration module is used to detect the status of the second button and the third button; when it is detected that the second button and the third button are pressed at the same time, the simulation switching switch connects the USB interface and the slave 1860 chip; before the terminal enters the power-on mode, the slave 1860 chip controls the slave 1860 chip to execute the download of the 1860 system code.

After the present invention is connected to the power supply, the two buttons of the terminal itself, the second button and the third button, are used to press and hold these two buttons at the same time before downloading. Then the USB interface is inserted so that the voltage signal of the USB interface is respectively connected to the main 1860 chip and the slave 1860 chip. When the power-on detection configuration module detects that the two buttons are pressed at the same time, the state of the analog switching switch is controlled to connect the slave 1860 chip to the USB interface, and before the terminal enters the power-on mode, the slave 1860 chip executes the download of the 1860 system code. It can be seen from this that the present invention is simple to operate, and there is no need to fully power on the terminal. The download and installation of the system code from the slave 1860 chip can be completed before the terminal is powered on. It solves the problem in the prior art that the terminal must be fully started first, then the menu is selected, and finally the download can be realized by clicking the corresponding command in the menu.

In another embodiment, the terminal further has a first button; the first button is connected to the main 1860 chip;

The first button is used to switch the BOOT state of the startup code before the terminal is turned on. The main 1860 chip executes the download of the 1860 system code before the terminal enters the boot mode.

The present invention switches the BOOT state of the startup code before the terminal is turned on by the first button, so that before the terminal enters the boot mode, it first executes the download task of the 1860 code on the main 1860 chip, waits for the download time of the preset time period, and then decides whether to enter the boot mode. If the download fails, the terminal is turned on after the preset time period. If the download is successful, the boot detection configuration module detects the state change of the second button and the third button. If it is detected that they are pressed at the same time, the analog switch is switched to execute the download task from the 1860 chip. The download is successful, the terminal is not turned on, and the download fails.
