Description
Technical Field
The invention relates to the technical field of computer production, in particular to a method for updating a universal unique identification code based on a serial port.
Background
With the development of technology, the related technology of computers is continuously updated, and the production process is continuously improved. However, when the motherboards are produced in a factory at present, the universal unique identification code (UUID) on each motherboard still needs to be manually written under the DOS by using batch files, and a manufacturer in large spots also needs to start the motherboard to be written under the DOS by using a code scanner. The flash is performed by batch processing, the flash is started to DOS, and the flash is manually performed, so that the time and the labor are wasted; the code scanner is used for writing, so that the cost is high and the efficiency is low.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for updating a universal unique identification code based on a serial port, which can effectively reduce hardware cost and improve production efficiency.
In order to solve the technical problem, the invention provides a method for updating a universal unique identification code based on a serial port, which comprises the following steps:
(1) the control platform is connected with the mainboard through a serial port line;
(2) the firmware of the mainboard is configured with a corresponding serial port;
(3) the control platform opens the update software, responds to the firmware request of the mainboard through the serial port, and automatically updates the universal unique identifier UUID.
Preferably, in the step (2), the configuration of the corresponding serial port by the firmware specifically includes:
(21) starting up to a designated program, initializing a function from a serial port to UpDateUUID, sending a BYOUS instruction to the control platform through the serial port, and requesting to write in the UUID;
(22) after the host board receives the UUID through the serial port and the UUID is refreshed, the UUID is stored in a module FV in firmware appointed by the firmware, and the firmware sends an ending instruction through the serial port;
(23) the next time the computer is powered on and started, the firmware calls a designated program UpdateUUID to write the UUID into TYPE1 by updating an SMBIOS table;
(24) if 16 Byte positions behind Offset 08h are all 00 or all FF, updating the UUID in the FV to TYPE1 by updating the SMBIOS table; if not, the updating is not needed, and the operation is directly returned.
Preferably, in the step (3), the control platform receives a command sent by the serial port, and judges whether the command is a BYOUS; if the serial port is BYOUS, capturing UUIDs stored on the computer, arranging the UUIDs in the Buffer in sequence, and sending a first group of UUIDs to the serial port; if the command is BYOUE, the sending is finished, the Buffer pointer jumps to the address of the next group of UUIDs, and the command sent by the serial port is waited to be received.
The invention has the beneficial effects that: the invention can effectively reduce hardware cost, save startup time, improve production efficiency and reduce labor cost.

Detailed Description
As shown in fig. 1 and 2, a method for updating a universal unique identification code based on a serial port includes the following steps:
(1) the control platform is connected with the mainboard through a serial port line;
(2) the firmware of the mainboard is configured with a corresponding serial port;
(3) the control platform opens the update software, responds to the firmware request of the mainboard through the serial port, and automatically updates the universal unique identifier UUID.
The mainboard sends a request command, the control platform receives the command and sends the UUID to the mainboard. The motherboard receives the UUID and stores the content in FV.
As shown in fig. 3, in step (2), the configuration of the serial port corresponding to the firmware specifically includes:
(21) starting up to a designated program, initializing a function from a serial port to UpDateUUID, sending a BYOUS instruction to the control platform through the serial port, and requesting to write in the UUID;
(22) after the host board receives the UUID through the serial port and the UUID is refreshed, the UUID is stored in a module FV in firmware appointed by the firmware, and the firmware sends an ending instruction through the serial port;
(23) the next time of power-on and startup, firmware calls a designated program UpdateUUID, and an SMBIOS table is updated, wherein the SMBIOS table is specifically a System Management BIOS System Management BIOS, is a standard for transmitting Management information through System firmware, 127 TYPEs are totally arranged in the SMBIOS table, and the UUID is written into TYPE 1;
(24) if 16 Byte positions behind Offset 08h are all 00 or all FF, updating the UUID in the FV to TYPE1 by updating the SMBIOS table; if not, the updating is not needed, and the operation is directly returned.
In the step (3), the control platform receives a command sent by the serial port and judges whether the command is a BYOUS; if the serial port is BYOUS, capturing UUIDs stored on the computer, arranging the UUIDs in the Buffer in sequence, and sending a first group of UUIDs to the serial port; if the command is BYOUE, the sending is finished, the Buffer pointer jumps to the address of the next group of UUIDs, and the command sent by the serial port is waited to be received.
The invention saves hardware cost, saves startup time, improves production efficiency and reduces labor cost.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
