Detailed Description

The structural and operational principles of the present invention are described in detail below with reference to the accompanying drawings:

as shown in fig. 1, a power-up-free electronic device for updating on-board data according to a first embodiment of the present invention is disclosed. The electronic device can be a motherboard, a server, a computer host or a quasi-system host. The electronic device of the first embodiment is illustrated by taking a motherboard 10 as an example. The motherboard 10 includes a board body 100, a system electronic circuit 200, a power connector 300, a first network socket 251, one or more erasable memories 410,420, an embedded controller 500, and a second network socket 522.

As shown in fig. 1, the board body 100 may be a printed circuit board having a printed circuit for providing electrical connection. The board 100 does not exclude other board types, and the electrical connection between the components is achieved by wires. The system electronic circuit 200 is disposed on the board 100 to provide the functions required by the motherboard 10. The power connector 300 is disposed on the board 100 and electrically connected to the system electronic circuit 200, and is configured to receive an operating power WP and output a standby power SP. An example of the power connector 300 is an ATX 24pin socket, which can receive power at different voltages and provide power to different electronic components. The broken line shown in the figure represents a power transmission line.

As shown in fig. 1, the first network socket 251 is electrically connected to the system electronic circuit 200. The first network socket 251 is used for connecting a plug of a network cable for connecting the system electronic circuit 200 to a network.

As shown in FIG. 1, the erasable memory 410,420 is disposed on the board 100, and the erasable memory 410,420 has a target storage area. The target storage area stores a program code. The erasable memory 410,420 is mainly used for electronic components requiring storing firmware, i.e. program codes, including but not limited to basic input/output system (BIOS), baseboard management controller (Baseboard Management Controller, BMC), complex programmable logic device (Complex Programmable Logic Device, CPLD), power supply firmware or graphics processor firmware. The types of erasable memory 410,420 include, but are not limited to, EPROM, EEPROM, or flash memory (flash memory). Therefore, each motherboard 10 may have multiple erasable memories 410,420 at the same time, and need to perform the firmware update operation.

As shown in fig. 1 and 2, the embedded controller 500 may be an electronic device on the motherboard 10, such as a Baseboard Management Controller (BMC), a keyboard controller, a complex programmable logic device, or other microcontrollers, which receives signals, executes program codes, and outputs corresponding signals. The embedded controller 500 and the second network socket 522 are disposed on the board 100. The embedded controller 500 is electrically connected to the erasable memory 410,420, and receives the standby power SP from the power connector 300. The embedded controller 500 has a second network interface 520, and the second network interface 520 is connected to the second network socket 522. The second network interface 520 is also a plug connection for a network line so that the embedded controller 500 can be connected to a network through the second network interface 520. Alternatively, the embedded controller 500 may interface directly with another device via a network line and establish a communication connection via a network protocol (e.g., a TCP/IP protocol). Through the second network socket 522 and the second network interface 520, the embedded controller 500 receives an externally input writing command and an image file, and writes the image file into the target storage area of the erasable memory 410,420 by using the writing program, thereby overwriting the program code (firmware).

As shown in fig. 1 and 2, the embedded controller 500 further stores a programming program. After receiving the standby power SP, the embedded controller 500 starts to initialize, load and execute the recording program to enter a waiting recording state, as shown in step S110. Then, the embedded controller 500 can receive the recording command and the image file through the second network socket 522 and the second network interface 520, as shown in step S120. The embedded controller 500 receives the burning command and the image file and stores the image file into the temporary memory 510, as shown in step S130.

Referring to fig. 2 and 3, the embedded controller 500 then executes a verification procedure on the image file to confirm the correctness of the image file. As shown in Table I, the record format of the image file at least comprises a header (header), content (Content) and a check sum (check sum). Sometimes, the version number (version) of the image file is also included. The header is used to confirm that the received file is a usable image file and sometimes also contains information of the applicable device, i.e., identification information of the erasable memory 410,420 as the writing target. The identification information may be recorded in a version number. The content is the information that is expected to be written to the erasable memory 410,420, i.e., the firmware program to be written. The check code is a value which is supposed to be after the image file is calculated through a specific check algorithm, and is used for confirming whether the content of the received file is damaged or not. Common parity algorithms include MD5 and SHA1.

The validation process determines whether the received file is an image file. The embedded controller 500 reads the bytes of the corresponding header, and determines whether the header belonging to the image file exists according to the information of the bytes to confirm that the received file is the image file, as shown in step S140. The absence of the header includes that the received file is not an image file or that the received file is not an image file suitable for use with the motherboard 10.

If the header of the image file does not exist, the embedded controller 500 outputs a file error notification, as shown in step S170.

If the header of the image file exists, the received file is confirmed as the image file. The embedded controller 500 performs a check code operation on the image file to confirm whether the result of the check code operation matches the check code of the image file, as shown in step S150. If the result of the check code operation does not conform to the check code of the image file, which means that the content of the image file is damaged or belongs to the error content, the embedded controller 500 also outputs a file error prompt, as shown in step S170.

If the result of the check code operation matches the check code of the image file, which indicates that the content of the image file is correct, the embedded controller 500 performs the writing operation by using the writing program, and writes the image file into the target storage area of the specified erasable memory 410,420, as shown in step S160. As previously indicated, the target identification information for a given erasable memory 410,420 may be included in a header or version number. In an electronic device having multiple erasable memories 410,420, the image file must be written to the correct erasable memory 410,420. Therefore, the image file must contain the target identification information corresponding to the specified erasable memory 410,420, so that the embedded controller 500 can correctly write to the specified erasable memory 410,420.

Referring to fig. 4, a block diagram of a specific circuit of the motherboard 10 according to the first embodiment is shown. As described above, the system electronic circuit 200 shown in fig. 1 is used to provide the basic functions of the motherboard 10. The system electronics 200 generally includes a central processor 210, a system chipset 220, a system memory 230, a graphics processor 240, a first network interface 250, a power control circuit 260, and the necessary buses. The system chipset 220 is a circuit chip for handling I/O operations between the cpu 210 and other devices, including but not limited to a path controller (Control Hub), a motherboard controller (Board Management Control, BMC), a combination of a south bridge chip and a north bridge chip of a logic chip (logic IC), a platform path controller (Platform Control Hub, PCH), an I/O path controller (I/O Control Hub, ICH), AMD Fusion Controller Hub, etc. The system chipset 220 and its components are not essential to the present invention, and their details are not described in detail below. As previously described, the power provided through the power connector 300 may be directly transferred to the various electronic components or may be indirectly transferred to the various electronic components through the power control circuit 260. The power control circuit 260 may be used to determine whether to supply power or not, or further perform voltage transformation (e.g., dc-dc conversion) and then transmit the power to the target electronic device. The first network socket 251 is electrically connected to the first network interface 250, and the first network interface 250 is used for providing a network connection function, so that the motherboard 10 is provided with an On-board (On-board) network connection device.

Referring to fig. 5 and 6, a second embodiment of the invention provides an electronic device package assembly, which includes an electronic device and a package box 20. The electronic device of the second embodiment is illustrated by the motherboard 10. The system electronics 200, the embedded controller 500, and the erasable memory 410,420 are shown in simplified illustration and are not intended to depict the actual form of the system electronics 200.

As shown in fig. 5 and 6, the package 20 is used for accommodating an electronic device, that is, the package 20 accommodates the board body 100 of the motherboard 10. The package 20 has at least one opening 22. The at least one opening 22 is positioned corresponding to the second network jack 522 and the power connector 300. In the second embodiment, the package 20 has two openings 22, and each opening 22 is located corresponding to the second network socket 522 and the power connector 300. If the relative positions of the second network socket 522 and the power connector 300 are close and the plugging directions are the same, it is not excluded that the single opening 22 corresponds to the second network socket 522 and the power connector 300 at the same time.

Therefore, as shown in fig. 5, in the case where the package 20 wraps the motherboard 10, the second network socket 522 and the power connector 300 are still exposed, and the network cable and the external power EP can be connected. Therefore, in the case where the package 20 is not disassembled, the embedded controller 500 may still perform the burning operation while updating the firmware of the target electronic component. That is, after the motherboard 10 is manufactured and packaged, the firmware of the target electronic component can be updated without disassembling the package 20 to take out the motherboard 10.

As shown in fig. 5, the openings 22 may be closed with a seal 24 when no burning operation is required. The seal 24 may be a resilient plug or a adhesively secured sheet. As shown in fig. 6, the packaging case 20 may be provided with a buffer member 21 interposed between the electronic device (i.e., the board body 100) and the inner side 20a of the packaging case 20 to buffer and protect the motherboard 10.

Referring to fig. 7 and 8, the package 20 further includes a spacer 26, and a tubular channel 261 is provided, wherein the tubular channel 261 extends from the edge of the opening 22 toward the second network socket 522 or the power connector 300, such that the spacer 26 surrounds the second network socket 522 or the power connector 300 (the power connector 300 is illustrated in the drawing). The function of the spacer 26 is to allow the outside world to access only the second network socket 522 or the power connector 300 through the opening 22, but not the other parts of the motherboard 10, thereby reducing the probability of the motherboard 10 being damaged by objects passing through the opening 22.

As shown in fig. 9, the spacer 26 shown in fig. 7 and 8 has a thin-walled structure, but the spacer 26 may actually have a block-shaped structure with a tubular channel 261, and be made of a buffer material or designed to have a buffer structure, and the spacer 26 is disposed between the electronic device (i.e., the board body 100) and the inner side 20a of the package 20. At this time, the spacer 26 may serve as the buffer 21, and the tubular channel 261 is reserved for the power line or the network line to pass through, and the second network socket 522 is connected to the power connector 300 from the outside of the package 20.

Referring to fig. 7 and 8, the package 20 further includes a reinforcing member 28 coupled to the inner side 20a of the package 20 and surrounding the opening 22. The stiffening members 28 serve to strengthen the structural strength around the aperture 22, avoiding local lack of strength of the package 20 due to the aperture 22. The opening of the stiffener 28 may be smaller than the aperture 22 as in fig. 7, such that the edge of the stiffener 28 protrudes into the aperture 22 in the radial direction of the aperture 22, forming an inwardly extending flange. The seal 24 is sized to fit completely within the opening 22 and is secured by being adhered to the outside of the stiffener 28. Thus, the seal 24 can maintain the appearance of the package 20 flat when closing the aperture 22 without forming a protruding structure.

Referring to fig. 10 and 11, through the second network interface 520 and the second network socket 522, the embedded controller 500 can directly interface with the client 600 through a network line, and establish a communication connection through a network communication protocol. The electronic components associated with the system electronics 200 are omitted from fig. 9 to simplify the drawing.

As shown in fig. 11, the embedded controller 500 executes a host program for the client 600 to connect to perform the writing operation through the second network interface 520 and the second network socket 522. The host program executes a web service and sets a local link address. The client 600 executes a browser, and the web service from the embedded controller 500 loads a menu screen to be displayed on the client 600.

Referring to FIG. 12, a menu screen example is shown in which a user may select a mapping file format (i.e., select a erasable memory 410,420 as a target for writing) from a drop-down menu. Then, the image file path field is used to select the image file from the storage device (built-in or external) of the client 600. After confirming that the writing operation is performed, the host program receives the writing instruction and the image file from the client 600 through the connection with the browser of the client 600, and drives the embedded controller 500 to perform the writing operation as shown in fig. 2. The recording results of the file error prompt or the recording completion prompt in step S170 may be returned to the client 600 by the host program and displayed in the execution result field of the menu screen.

The function of providing the web service for the client 600 to connect is that the operation of the burning operation can be performed by the client 600. Therefore, the electronic device can execute the burning operation to update the on-board data without actually connecting the display and the input interface (such as a keyboard and a mouse) for normal startup.

Referring to fig. 13 and 14, an electronic device capable of updating on-board data without power-on is disclosed in a third embodiment of the present invention. The electronic device of the third embodiment takes a host computer 30 as an example. The computer host 30 has a housing 32, a power supply 34, and the motherboard 10 according to the first embodiment. The computer host 30 may be a desktop computer, a notebook computer, a server host with complete functions, or a quasi-system.

As shown in fig. 13 and 14, the power supply 34 and the board body 100 of the motherboard 10 are mounted in the housing 32, and the power supply 34 has a power socket 342 and an output connector 344. The power socket 342 is used for receiving an external power EP and converting the working power WP. The output terminal 344 is configured to be connected to the power connector 300 to output the working power WP to the power connector 300.

As shown in fig. 12 and 13, the casing 32 has one or more windows 322, and the power supply 34 and the motherboard 10 are installed in the casing 32, so that the first network socket 251, the second network socket 522 and the power socket 342 are disposed corresponding to the windows 322 and exposed through the windows 322. The window 322 may be unitary such that the first network jack 251, the second network jack 522, and the power jack 342 are exposed through the same window 322. The number of windows 322 may be plural, so that the first network socket 251, the second network socket 522, and the power socket 342 are exposed through one window 322.

The computer 30 of the third embodiment may also be packaged by the packaging box 20 of the second embodiment to form a packaging assembly of the computer 30.

As shown in fig. 15, a fourth embodiment of the invention provides an electronic device package assembly, which comprises an electronic device and a package box 20. The electronic device of the fourth embodiment is illustrated as a host computer 30.

As shown in fig. 14, in the fourth embodiment, the package 20 is used for accommodating the computer host 30. The package 20 has at least one opening 22. The at least one opening 22 may be located corresponding to the second network socket 522 and the power connector 300, and may further correspond to the first network socket 251. In the fourth embodiment, the package 20 has three openings 22, and each opening 22 is located corresponding to the first network socket 251, the second network socket 522 and the power connector 300.

As shown in fig. 14, when the package 20 encloses the computer host 30, the second network socket 522 and the power connector 300 are still exposed, and can be connected to a network cable and an external power EP. Therefore, in the case where the package 20 is not disassembled, the embedded controller 500 may still perform the burning operation while updating the firmware of the target electronic component. That is, after the computer 30 is manufactured and packaged, the firmware of the target electronic component can be updated without disassembling the package 20 to take out the computer 30.

The package 20 of the fourth embodiment also has the sealing member 24, the cushioning member 21, the spacer 26, and the reinforcing member 28 as described in the second embodiment. Wherein the spacer 26 is instead disposed between the housing 32 and the inner side 20a of the package 20. The spacer 26 is also used to provide a tubular passage 261 such that the tubular passage 261 extends from the edge of the aperture 22 toward the second network socket 522 or the power connector 300 such that the spacer 26 surrounds the second network socket 522 or the power connector 300. The function of the spacer 26 is to allow the outside world to access only the second network socket 522 or the power connector 300 through the opening 22, but not the other parts of the computer host 30.

By using the electronic device formed by the motherboard 10, the on-board data can be updated only by providing standby power and network connection without disassembling the electronic device, especially the assembled computer host. After the electronic device further combines with the package 20, the on-board data update can be performed even if the package 20 is not unpacked. Thus, management of inventory electronics is facilitated.

Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
