Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a fuse configuration device. Background Art

[0002] In today's electronic devices, the configuration versions of the systems or software used may vary depending on factors such as different regions. If a user downloads an operating system with a different configuration version, the user's electronic device may not operate normally, causing the user to not achieve his or her goal, but also wasting time and reducing the user's experience.

[0003] At present, a fuse mechanism is used to solve the above problems. Specifically, in the production process of electronic equipment, corresponding materials are added to the internal mainboard of the electronic equipment according to the configuration version compatible with the electronic equipment, so that the mainboard GPIO port can present different high and low states according to different configuration versions of the operating system. When the user downloads the operating system, the GPIO port of the mainboard inside the electronic equipment will confirm the configuration version information of the operating system. If the software configuration version information is incompatible with the electronic equipment, the subsequent software download and installation will not be performed. The prior art uses this fuse mechanism to confirm in advance the configuration version of the operating system that the electronic equipment is compatible with, thereby avoiding the problem that the user downloads an operating system different from the configuration version of the electronic equipment, resulting in the software not being able to be used normally, and improving the user's applicable experience. However, for each configuration version, it is necessary to add corresponding materials to the internal mainboard of the electronic equipment and occupy a GPIO port of the mainboard. Since the GPIO port cannot be reused, it will increase the cost and occupy too much mainboard resources. Utility Model Content

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] Before introducing a fuse configuration device proposed in an embodiment of the present disclosure, a fuse detection method used in the prior art is first introduced to facilitate easier understanding of the present solution later.

[0039] During the production process of electronic devices, corresponding materials are added to the motherboard inside the electronic device according to the configuration versions that the electronic device is compatible with, so that the motherboard GPIO port can present different high and low states according to different configuration versions of the operating system. Then, when configuring the system version, the high and low states of the motherboard GPIO terminal are read to determine which configuration versions the electronic device is compatible with.

[0040] Figure 1 This is a diagram of the GPIO port responsible for version configuration on the terminal device motherboard. Figure 1 The example given includes five GPIO ports, namely BOARD_ID4, BOARD_ID3, BOARD_ID2, BOARD_ID1 and BOARD_ID0. The configuration corresponding to the terminal device is determined by the different level states of these five GPIO ports.

[0041] Figure 2 It is the configuration corresponding to the high and low states of the GPIO port on the terminal device motherboard. Figure 2 In the given example, the corresponding system version is configured according to different regions.

[0042] like Figure 2As shown in the figure, five regions are given, including: Global, NA, WIFI, CHN, KREAN and Data Only. When the BOARD_ID4-153, BOARD_ID3-32, BOARD_ID2-31, BOARD_ID1-60 and BOARD_ID0-59 terminals of the GPIO port all output low levels, it means that the terminal device is compatible with the system configuration version of the Global region; when the BOARD_ID0-59 terminal of the GPIO port outputs a high level, and the other BOARD_ID4-153, BOARD_ID3-32, BOARD_ID2-31 and BOARD_ID1-60 terminals output low levels, it means that the terminal device is compatible with the system configuration version of the NA region; when the BOARD_ID1-60 terminal of the GPIO port outputs a high level, and the other BOARD_ID4-153, BOARD_ID3-32, BOARD_ID2-31 and BOARD_ID0-59 terminals output low levels, it means that the terminal device is compatible with the system configuration version of the WIFI region. This; when the BOARD_ID2-31 end of the GPIO port outputs a high level and the other BOARD_ID4-153, BOARD_ID3-32, BOARD_ID1-60 and BOARD_ID0-59 ends output a low level, it indicates that the terminal device is compatible with the system configuration version of the CHN area; when the BOARD_ID3-32 end of the GPIO port outputs a high level and the other BOARD_ID4-153, BOARD_ID2-31, BOARD_ID1-60 and BOARD_ID0-59 ends output a low level, it indicates that the terminal device is compatible with the system configuration version of the KREAN area; when the BOARD_ID4-153 end of the GPIO port outputs a high level and the other BOARD_ID3-32, BOARD_ID2-31, BOARD_ID1-60 and BOARD_ID0-59 ends output a low level, it indicates that the terminal device is compatible with the system configuration version of the Data Only area.

[0043] In the above-mentioned prior art, the system configuration version compatible with this device is determined by adding corresponding materials and the high and low states of the GPIO port on the mainboard of the electronic device. When the user downloads the operating system, the GPIO port of the mainboard inside the electronic device will confirm the configuration version information of the operating system. If the software configuration version information is incompatible with this electronic device, the subsequent software download and installation will not be performed. The prior art uses this fuse mechanism to confirm in advance that the electronic device is compatible with the configuration version of the operating system, thereby avoiding the problem that the user downloads an operating system different from the configuration version of the electronic device, resulting in the software not being able to be used normally, and improving the user's applicability experience. However, for each configuration version, it is necessary to add corresponding materials to the mainboard inside the electronic device and occupy a GPIO port of the mainboard. Since the GPIO port cannot be reused, it will increase costs and occupy too many mainboard resources.

[0044] The disclosed embodiment provides a fuse configuration device. The fuse configuration device provided in the disclosed embodiment first burns the configuration information into the fuse configuration chip of the fuse configuration device, and then confirms whether the configuration information is accurate through a display output device connected to the fuse configuration chip, and finally inserts the data output interface of the fuse configuration device into the device terminal, and transmits the configuration data to the device terminal through the fuse configuration chip. Therefore, the fuse configuration device provided in the disclosed embodiment improves the efficiency of version configuration of the terminal device by storing the configuration information in the fuse configuration chip and then transmitting it to the terminal device; and the version configuration process can be implemented without adding materials to the terminal device, thereby reducing production costs. The device terminals that can be applied to the fuse configuration device provided in this solution include mobile phones, tablets, computers and other portable devices.

The display output device proposed in this scheme includes at least one indicator light, and each indicator light is connected to the corresponding display control port in the fuse configuration chip. When the fuse configuration chip stores a type of fuse configuration information, the corresponding indicator light can be lit, so that the staff can more clearly identify what type of fuse configuration information is stored in this fuse configuration device, thereby improving the accuracy of the operating system configuration version of the device terminal, and at the same time, to a large extent, avoiding the occurrence of configuration errors when the staff configures the terminal device, thereby improving the configuration efficiency of the operating system of the device terminal.

First, the standard USB interface is divided into Type-A and Type-B. Type-A and Type-B can be divided into USB 2.0 and USB 3.0 standard USB interfaces according to the different USB standards supported. Type-A interfaces are widely used in devices such as mice, keyboards, and U disks, while Type-B interfaces are often used in devices such as printers and special displays. Secondly, the Mini USB interface is mainly divided into Mini-A and Mini-B. The Mini USB interface is a small USB interface with the same indicators as the standard USB, but an ID pin is added to support the OTG function.

[0072] The embodiment of the present disclosure provides a fuse configuration device, which completes the transmission of configuration information through a serial clock pin (SCL) and a serial data pin (SDA), so this scheme adopts the I2C protocol to transmit information. Since the I2C interface has the characteristic of being reusable, it is not necessary to add materials on the terminal device motherboard like the prior art, and occupy a large number of GPIO interfaces, saving a large number of materials on each terminal device, saving the GPIO interface or ADC interface resources of the terminal device motherboard, using the I2C general interface on the terminal device motherboard and the characteristics that the I2C interface can be expanded to 127, to confirm which configuration versions of the operating system are compatible with the terminal device, and cooperate with the fuse configuration device proposed in this scheme to achieve the purpose. Therefore, the working process of the fuse configuration device proposed in this scheme is: through the fuse configuration chip that can store software configuration version data set inside the fuse configuration device, the software configuration version data in the fuse configuration chip is transmitted to the internal main board of the terminal device through the I2C protocol using the two pins SBU1 and SBU2 of the data output interface, and the main board determines which operating system versions are compatible with the terminal device by reading the fuse configuration chip data, so as to indicate which version of the operating system can only be installed.

[0073] Therefore, the fuse configuration device proposed in this solution uses the I2C protocol to transmit the software configuration version, making full use of the reusable I2C port on the terminal device motherboard, increasing the utilization rate of motherboard resources, reducing production costs, and improving the accuracy of the terminal device's operating system configuration version. After the download of the fuse is completed, no additional materials are added to the terminal device, so the fuse configuration device can be reused by burning.
