Problems solved by technology

[0003] However, when the upgrade package is transmitted through the I2C bus, because the serial transmission bus is used, the transmission speed is very slow and unstable, and sometimes packet loss may occur. Even if the lost package is resent, it will cause the first The terminal waits for a long time to upgrade, which reduces the efficiency of the first terminal when upgrading

Embodiment Construction

[0058] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0059] Such as figure 1 As shown, in one embodiment of the present invention, an upgrade control method is provided, which is applied to the first terminal. The two terminals establish a communication connection in advance, the second terminal can refer to the main control chip of the TV end, the second terminal can pre-set the USB OTG function, that is, it has two working modes: USB master mod...

Abstract

The embodiment of the present invention provides an upgrade control method and device, which are applied to the first terminal, including: when receiving the upgrade command sent by the second terminal, generating a A mode switching instruction of the device mode is sent to the second terminal; when the mode identifier of the second terminal is read, it is determined that the mode switching of the second terminal is completed; an upgrade package acquisition request is sent to the second terminal so that the second terminal acquires the upgrade package at a preset storage location according to the data package acquisition request; when receiving the upgrade package sent by the second terminal, uses the upgrade package to perform the upgrade. The present invention can use the second terminal to obtain the upgrade package from the preset storage location after the second terminal is switched to the USB slave mode, the data transmission is more stable, the data transmission speed is fast, and the waiting time for the first terminal is short when it needs to be upgraded.

Description

technical field [0001] The invention relates to computer technology, in particular to an upgrade control method and device. Background technique [0002] At present, the main control chip of the TV terminal and the display terminal are generally connected through the I2C bus. Therefore, data is generally transmitted between the main control chip and the display terminal through the I2C bus, for example: in the software upgrade of the smart TV display terminal In this case, firstly, the upgrade package is sent to the display screen through the I2C bus provided between the main control chip of the TV terminal and the display screen, and then the display screen is upgraded using the upgrade package. [0003] However, when the upgrade package is transmitted through the I2C bus, because the serial transmission bus is used, the transmission speed is very slow and unstable, and sometimes packet loss may occur. Even if the lost package is resent, it will cause the first The time fo...
