Problems solved by technology

[0009] This method requires that the tablet computer to be upgraded must already have a system running, otherwise it cannot connect to the network, which cannot be done for a tablet that has just been produced without system firmware
Moreover, this method also has problems such as the inability to conveniently display mass production progress information on the other party's platform tool during the upgrade process.

Embodiment Construction

[0053] The firmware upgrade method, host device and system provided by the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0054] Because quite a few of the current tablet computers run the Android system, if it is possible to upgrade the firmware of the tablet computer under the Android system, you can directly use the host-side tablet computer A to update the client-side tablet computer B without the participation of a Windows-based PC. Perform mass production upgrades.

[0055] Such as figure 1 As shown, the tablet computer A running the Android system acts as the USB Host, and the tablet computer B acts as the USB device client and waits for the firmware to be programmed.

[0056] Based on the above connections, such as figure 2 As shown, the method that the host end equipped with the Android system provided by the embodiment of the present invention performs firmware upgrade on the client side, com...

Abstract

The invention relates to a method for firmware upgrading, and a host side device and system. The method comprises the following steps that a host side operates a USB (Universal Serial Bus) host controller to detect whether a to-be-upgraded client is inserted into a local USB interface through a USB host controller driver; if detecting that the to-be-upgraded client is inserted, the host side downloads an initializer and a firmware upgrading program to the client through a firmware upgrading program, the initializer is used for initializing an internal memory of the client, the firmware upgrading program is downloaded in the initialized internal memory for analyzing and executing all kinds of commands received from the host side; and the host side sends a firmware burning command and firmware data to the client through the firmware upgrading program, and after the client receives the firmware burning command and the firmware data, the firmware data is written into a storage medium through the firmware upgrading program on the client according to the firmware burning command. According to the method for firmware upgrading, and the host side device and system, the production cost can be effectively reduced, the mass production number at the same time is greatly improved, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a firmware upgrade method, a host device and a system. Background technique [0002] During the upgrade process of the current tablet PCs after mass production, the following methods are usually used for firmware upgrades: [0003] 1) Use a Windows PC to upgrade the firmware of multiple tablet computers [0004] Windows PC is used to upgrade the tablet computer. By sending commands and firmware upgrade programs to the tablet computer, it can interact with the tablet computer to obtain the progress and success information of the upgrade. [0005] However, this method requires PCs loaded with Windows systems to participate. Therefore, when faced with thousands of tablets produced on the production line of the factory, the number of PCs loaded with Windows systems will limit the speed of mass production. , and the cost of configuring multiple PCs is also high. [0006] ...
