Abstract

An automatic entrance device in accordance with the present invention performs software upgrade by starting up a terminal in an upgrade boot mode by holding operation of a memory when a USB interface of a terminal is connected to an external device, and starts up the terminal in a normal boot mode by a processor accessing memory by disabling hold of operation of memory when the USB interface and external device are disconnected.

Description

technical field [0001] Embodiments of the present invention relate to an automatic entry device and method for upgrading a startup mode when a terminal starts up. Background technique [0002] The terminal starts to operate by a processor that reads startup software, that is, startup data stored in the SPI flash memory. This is called normal boot mode. [0003] In a specific case, for example, when the terminal is connected to a computer or the like to update boot data, the terminal should work in the update boot mode. [0004] However, if the boot data is already stored in the SPI flash, the processor reads the boot data stored in the SPI flash with the highest priority. Therefore, the terminal works in the normal boot mode instead of the upgrade boot mode, and thus the boot data cannot be upgraded. Contents of the invention [0005] An embodiment of the present invention provides an automatic entry device and method for an upgrade startup mode, which allows a terminal...
