It should be noted that the start flag may be a control switch disposed on the periphery of the electronic device, where the control switch may control a level of a General Purpose Input/Output (GPIO) pin of the electronic device, and for example, the first level may be a high level, the second level may be a low level, when the control switch is in an "on" state, the level of the GPIO is a high level, and at this time, the state of the start flag may be the first state; when the control switch is in an off state, the level of the GPIO is low, and the state of the start flag may be the second state. When the upgraded system of the electronic device runs and has a problem, the user can be informed of dialing the control switch to the off position in a notification mode such as a display device or a specification of the electronic device, so that the level of the GPIO is low. Thus, when bootloader is started, reading GPIO is low level, and system reading from the second area of flash memory unit is selected.
It should be noted that, when the state of the start flag is the second state, when the electronic device is powered off and restarted, the second system is also loaded with priority until the user performs an operation again (pressing a specific key of the remote controller or dialing back the control switch, etc.).
According to the system starting method provided by the embodiment of the application, after the upgraded first system is loaded on the electronic equipment, if the program of the electronic equipment runs abnormally in the first system, the state of the starting mark can be changed from the first state to the second state through controlling, so that the program before upgrading is preferentially loaded after the electronic equipment is restarted, and the second system which runs normally runs can be operated.
