The result of enabled configuration item is configured, or is only prejudged the results of specified GPIO pin voltage levels and set
It sets.System environment variable can flexible setting as the case may be, do not limit the present invention.
Further, the memory specified if it does not exist enables configuration item, then according to the logical of the smart machine main control chip
With the voltage value of input/output pin, judge whether the smart machine supports internal storage starting；It, will if supporting internal storage starting
The system environment variable is set as supporting internal storage starting；If not supporting internal storage starting, the system environment variable is arranged
Not support internal storage starting.
Specifically, if there is no specified memories to enable configuration item in above-mentioned judgement configuration file, according to intelligent electricity
Depending on the voltage value of SOC chip GPIO pin, judge whether smart television supports STR to start.For example, judging preassigned memory
Enable relevant GPIO pin voltage value (assuming that system defined GPIO pin voltage value be high level when indicate hardware
It does not support STR to start, hardware supported STR starting is indicated when which is low level).If the voltage value of the GPIO pin is
Low level, the system environment variable str_enable that the smart television is just arranged is true, indicates that smart television supports STR to open
Dynamic, if the voltage value of the GPIO pin is high level, the environmental variance str_enable that the TV is just arranged is false, table
Show that smart television does not support STR to start.
The present embodiment smart television can enable the facilities and SOC core of configuration item according to the memory specified in configuration file
The voltage condition of piece GPIO pin, system environment variable is arranged, to distinguish whether smart television supports STR to start, so as to intelligence
The selection STR starting of energy TV or cold start-up improve the flexibility of intelligent television system exploitation and reduce maintenance cost.
