Description

Technical Field

[0001] The embodiments of the present application relate to the field of computers, and more specifically, to a control device, method, apparatus, storage medium, and electronic device for chip programming. Background Art

[0002] With the continuous development of information technology, VR (Voltage Regulator) chips used for DC to DC (Direct Current to Direct Current) conversion have been continuously updated from the original analog technology to the current digital technology. Designers no longer need to perform cumbersome formula calculations and can complete the setting of functions such as the output voltage, loop compensation, and protection parameters of VR chips only through the I2C bus. The setting method is simple and easy to understand.

[0003] When developing and designing a server, designers often interconnect the I2C bus of the VR chip with the I2C bus of the BMC (Baseboard Management Controller) in the server. This design method can realize the monitoring function of the BMC for the VR chip. During the normal operation of the server, the BMC continuously polls and collects data through the I2C bus to obtain the voltage, current, and status information of the VR chip in real time. This function further accelerates the development of server information technology. In addition, during the normal use of the server, designers usually need to update and optimize the internal information of the VR chip, that is, the programming operation of the VR chip. The programming process of the VR chip is also realized through the I2C bus of the VR chip. That is, the I2C bus of the VR chip is connected to both the BMC and the VR programming tool at the same time. The polling status of the BMC needs to obtain the internal information of the VR chip, while at the same time, the VR programming tool needs to modify the internal information of the VR chip. Two types of data are transmitted on the I2C bus at the same time. The master priority of the BMC is higher than that of the VR programming tool and always occupies the I2C bus, which will cause the programming operation of the VR chip tool to fail and the relevant information of the VR chip cannot be changed online.

[0023] Hereinafter, embodiments of the present application will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0025] In the present application, a control device for chip programming is provided. Figure 1 is a schematic diagram of a control device for chip programming according to an embodiment of the present application, as Figure 1As shown in the figure, the control device for chip programming includes: a processor 12 and a switching module 14. Among them,

[0026] The switching module 14 is connected between the BMC deployed on the server and the server VR chip. The processor 12 is connected to the switching module 14. The processor 12 is also connected to the programming interface deployed on the server. The programming interface is used to directly connect the chip programming fixture to the server VR chip. The chip programming fixture is used to program the operation data into the server VR chip;

[0027] The processor 12 is used to detect the interface state of the programming interface; when the interface state is used to indicate that the chip programming fixture has been connected to the programming interface, a disconnection control signal is sent to the switching module 14. Among them, the disconnection control signal is used to indicate that the switching module 14 disconnects the connection between the BMC and the server VR chip; when it is determined that the switching module 14 has disconnected the connection between the BMC and the server VR chip, the chip programming fixture is controlled to program the server VR chip;

[0028] The switching module 14 is used to respond to the disconnection control signal and disconnect the connection between the BMC and the server VR chip.

[0029] Optionally, in this embodiment, the chip programming fixture is directly connected to the server VR chip through the chip programming interface, that is, the chip programming fixture does not pass through the connection link between the BMC and the VR chip when connected to the VR chip, so as to realize that the connection between the BMC and the VR chip can be controlled by the switching module without affecting the connection relationship between the chip programming fixture and the VR chip.

[0030] Optionally, in this embodiment, the BMC is used to monitor the VR chip, so as to collect the operation data in the VR chip.

[0031] Optionally, in this embodiment, the operation data is data used to indicate the operation state of the VR chip. The operation data may include, but is not limited to: the output voltage, loop compensation, protection parameters, etc. of the VR chip. This solution does not make a limitation on this.

[0032] Optionally, in this embodiment, detecting the interface state of the programming interface may be by detecting the level signal in the programming interface. That is, when the chip programming fixture is connected to the VR chip through the programming interface, the chip programming interface will generate a level change value, and then the interface state of the programming interface can be detected through the level change. Or, detecting the interface state of the programming interface may also be by detecting whether there is a programming signal for programming the VR chip in the programming interface. After detecting the programming signal, it is determined that the chip programming fixture is connected to the VR chip through the programming interface, thereby determining the interface state.

[0033] Optionally, in this embodiment, the open circuit control signal may be a control signal that directly controls the disconnection of the on-off module. Then, after receiving the open circuit control signal, the on-off module disconnects the connection between the BMC and the VR chip. Or, the open circuit control signal may also be a signal for indicating the interface state, such as a signal for indicating whether the chip programming fixture is connected to the VR chip through the programming interface. Then, after receiving the signal, the on-off module can determine whether the connection state between the BMC and the VR chip needs to be disconnected according to the interface state.

[0034] As an optional embodiment, the on-off module includes: a control unit and a target switch, where

[0035] The signal input end of the control unit is connected to the processor, the signal output end of the control unit is connected to the target switch, and the target switch is connected between the BMC and the server VR chip;

[0037] Optionally, in this embodiment, the control unit is further configured to receive a path control signal sent by the processor. This path control signal is sent to the control unit when the processor detects that the data programming of the server VR chip is completed. After receiving the path signal, the control unit determines that the data programming of the VR chip by the current chip programming fixture is completed and the connection between the BMC and the server VR chip needs to be connected. Therefore, a path control instruction is sent to the target switch, and this path control instruction is used to control the target switch to be connected.

[0038] Optionally, in this embodiment, the switch control instruction may be a control signal sent by the control unit. After the target switch receives this control signal, it performs an on / off operation corresponding to the control signal. This control signal may be, but is not limited to, a level signal, that is, when the target switch performs a disconnection operation and a connection operation, the received level signal values are different, and the target switch performs the corresponding on / off operation according to the received level signal value.

[0039] Through the above content, by setting the control unit and the target switch, with the target switch connected between the BMC and the VR chip, the control unit is used to control the disconnection of the target switch, thereby realizing the control of the connection link between the BMC and the VR chip through the control unit. When the chip burning fixture performs data burning on the VR chip, the connection link between the BMC and the VR chip is in a disconnected state, avoiding the influence brought by the burning operation of the BMC on the VR chip.

[0040] As an optional embodiment, the target switch includes: a first field-effect transistor and a second field-effect transistor, where

[0042] Optionally, in this embodiment, the first field-effect transistor may be a P-channel field-effect transistor, or it may also be an N-channel field-effect transistor.

[0043] Optionally, in this embodiment, the second field-effect transistor may be a P-channel field-effect transistor, or it may also be an N-channel field-effect transistor. The models of the first field-effect transistor and the second field-effect transistor deployed in the control device for chip burning may be the same or different, and this solution does not limit this.

[0044] Optionally, in this embodiment, the first end of the first field-effect transistor may be the source or the drain. Similarly, when the first end of the first field-effect transistor is the source, the second end of the first field-effect transistor is the drain, and when the first end of the first field-effect transistor is the drain, the second end of the first field-effect transistor is the source.

[0046] As an optional embodiment, the control unit includes: a complex programmable logic device, where the complex programmable logic device is used to convert the open-circuit control signal into a level signal, and the level signal is used to indicate the on / off state of the target switch, and the switch control instruction includes the level signal.

[0047] Optionally, in this embodiment, the control unit may further include a single-chip microcomputer. The signal input end of the single-chip microcomputer is connected to the processor, and the signal output end of the single-chip microcomputer is connected to the complex programmable logic device. The processor sends an indication signal for indicating whether the chip burning fixture is connected to the burning interface to the single-chip microcomputer. Then, after receiving the indication signal, the single-chip microcomputer determines whether to control the on / off of the connection between the BMC and the server VR chip, and then sends a path control signal (used to indicate that the connection between the BMC and the server VR chip is turned on) or an open-circuit control signal (used to indicate that the connection between the BMC and the server VR chip is turned off) to the complex programmable logic device. After receiving the path control signal or the open-circuit control signal, the complex programmable logic device generates a corresponding level signal and sends it to the target switch.

[0048] As an optional embodiment, the control device for chip burning further includes: an indicator light, where the indicator light is connected to the on / off module, where

[0049] The on / off module is further used to control the indicator light to turn on when receiving the open-circuit control signal.

[0050] Optionally, in this embodiment, the on / off state of the indicator light is used to indicate the on / off state of the connection between the BMC and the server VR chip. In this application, when the indicator light is on, the connection between the BMC and the server VR chip is in an open-circuit state. During actual use, it can also be set that when the connection between the BMC and the server VR chip is in an open-circuit state, the indicator light is controlled to turn off. This solution does not limit this.

[0051] Through the above content, by setting an indicator light connected to the on / off module, the connection state between the BMC inside the server and the server VR chip is characterized by the on / off state of the indicator light, so that the server management personnel can clearly determine the connection state between the BMC inside the server and the server VR chip according to the indicator light, which is convenient for the later maintenance of the server maintenance personnel.

[0052] Figure 2 It is an architecture diagram of a control device for chip programming according to an embodiment of the present application. As Figure 2 shown, the control device for chip programming includes a processor (host computer in the figure) and a switching module. The switching module includes a single-chip microcomputer, a CPLD (Complex Programmable Logic Device), a first field-effect transistor, a second field-effect transistor, and an indicator light. The host computer programming interface (I2C header) is connected (this programming interface can be a USB interface). The host computer is connected to the chip programming fixture through the programming interface. The chip programming fixture is directly connected to the server VR chip through this programming interface. The host computer is connected to the signal input end of the single-chip microcomputer through the USB interface. The host computer system software level includes a system for controlling the single-chip microcomputer and software for controlling the chip programming fixture, which can be implemented by python or other programs; the single-chip microcomputer is connected to the CPLD through GPIO lines; for the BMC I2C channel, a first field-effect transistor and a second field-effect transistor are added to the SDA and SCL buses. The gates of the two field-effect transistors are connected to the same signal of the CPLD. The conduction and cutoff of the field-effect transistors can be controlled through the CPLD, thereby controlling whether the BMC polls this I2C channel; at the same time, the signal output end of the GPLD is also connected to the indicator light. After the VR programming fixture is connected to the I2C header, the host computer will control the single-chip microcomputer. The single-chip microcomputer sends corresponding instructions to the CPLD through the GPIO lines. When the CPLD receives the instructions, it issues a low level to turn off the MOS transistors on the BMC SDA and SCL buses, realizing the interruption of this I2C path for the BMC to access the VR chip. At the same time, it does not affect the BMC to continue polling other I2C buses. In this way, the VR programming fixture can successfully program the VR FW. At the same time, the GPLD will also send a lighting instruction to the indicator light to control the indicator light to light up, so that the management personnel can know the on-off status of the connection between the internal BMC and the VR chip of the server according to the status of the indicator light.

[0053] The method embodiments provided in the embodiments of the present application can be executed on a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, Figure 3 It is a hardware structure block diagram of a mobile terminal for a control method of chip programming according to an embodiment of the present application. As Figure 3 shown, the mobile terminal may include one or more ( Figure 3 only one is shown in the figure) processors 302 (the processor 302 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 304 for storing data. Among them, the above mobile terminal may further include a transmission device 306 for communication functions and an input / output device 308. Those of ordinary skill in the art can understand, Figure 3The structure shown is only schematic and does not limit the structure of the above-mentioned mobile terminal. For example, the mobile terminal may further include more or fewer components than those shown in Figure 3 or have a different configuration from that shown in Figure 3 .

In some instances, the memory 304 may further include a memory remotely provided with respect to the processor 302, and these remote memories can be connected to the mobile terminal through a network. Examples of the above network include but are not limited to the Internet, enterprise intranet, local area network, mobile communication network, and combinations thereof.

[0055] The transmission device 306 is used to receive or send data via a network. Specific examples of the above network may include a wireless network provided by the communication provider of the mobile terminal. In one instance, the transmission device 306 includes a network adapter (Network Interface Controller, abbreviated as NIC), which can be connected to other network devices through a base station and thus communicate with the Internet. In one instance, the transmission device 306 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0056] In this embodiment, a control device for chip programming is provided. Figure 4 is a flowchart of the control method for chip programming according to the embodiments of the present application, as shown in Figure 4 . The process includes the following steps:

[0057] Step S402, detecting the interface state of the programming interface, where the programming interface is used to directly connect a chip programming jig to the server VR chip, and the chip programming jig is used to program the server VR chip with running data;

[0058] Step S404, when the interface status is used to indicate that the chip burning fixture has been connected to the burning interface, send a disconnection control signal to the on-off module deployed in the control device for chip burning. The control device for chip burning includes a processor and the on-off module. The on-off module is connected between the BMC deployed on the server and the server VR chip. The processor is connected to the on-off module, and the processor is also connected to the burning interface deployed on the server. The disconnection control signal is used to indicate the on-off module to disconnect the connection between the BMC and the server VR chip. The on-off module is used to respond to the disconnection control signal and disconnect the connection between the BMC and the server VR chip;

[0059] Step S406, when it is determined that the on-off module has disconnected the connection between the BMC and the server VR chip, control the chip burning fixture to burn the server VR chip.

[0060] Through the above steps, by setting a processor and an on-off module in the control device for chip burning, the on-off module is connected between the BMC deployed on the server and the server VR chip, the processor and the on-off module are connected, and the processor and the burning interface deployed on the server are connected. Thus, when it is detected that the burning fixture has been connected to the burning interface by detecting the interface status of the burning interface, the on-off module is instructed to disconnect the connection between the BMC and the server VR chip by sending a disconnection control signal. Furthermore, when the connection between the BMC and the server VR chip has been disconnected, the chip burning fixture is controlled to burn the server VR chip, avoiding the failure of data burning of the server VR chip caused by the BMC reading the data on the server VR chip, and realizing that the data burning process of the server VR chip is not interfered by the BMC. Therefore, problems such as low data burning efficiency of the chip can be solved, and the effect of improving the data burning efficiency of the chip can be achieved.

[0061] The above control method for chip burning is applied to the processor deployed on the control device for chip burning.

[0062] In the embodiment provided in the above step S402, detecting the interface status of the burning interface can be by detecting the level signal in the burning interface. That is, when the chip burning fixture is connected to the VR chip through the burning interface, the chip burning interface will generate a level change value, and then the interface status of the burning interface is detected through the level change. Or detecting the interface status of the burning interface can also be by detecting whether there is a burning signal for burning the VR chip in the burning interface. After detecting the burning signal, it is determined that the chip burning fixture is connected to the VR chip through the burning interface, and thus the interface status is determined.

[0063] Optionally, in this embodiment, the operation data is data used to indicate the operation state of the VR chip. The operation data may include, but is not limited to, the output voltage, loop compensation, protection parameters, etc. of the VR chip. This solution does not limit this.

[0064] Optionally, in this embodiment, when the interface state is used to indicate that the chip programming fixture is not connected to the programming interface, a path control signal is sent to the on-off module. The path control signal is used to instruct the on-off module to connect the connection between the BMC and the server VR chip. Thus, the BMC can read the data in the server VR chip.

[0065] In the embodiment provided in the above step S404, the open-circuit control signal may be a control signal directly controlling the on-off module to disconnect. Then, after receiving the open-circuit control signal, the on-off module disconnects the connection between the BMC and the VR chip. Or, the open-circuit control signal may also be a signal used to indicate the interface state, such as a signal used to indicate whether the chip programming fixture is connected to the VR chip through the programming interface. Then, after receiving the signal, the on-off module can determine whether the connection state between the BMC and the VR chip needs to be disconnected according to the interface state.

[0066] As an alternative embodiment, after controlling the chip programming fixture to program the server VR chip, the method further includes:

[0067] Detect the programming state of the server VR chip;

[0068] When the programming state is used to indicate that the chip programming fixture has finished programming the operation data to the server VR chip, a path control signal is sent to the on-off module, where the path control signal is used to instruct the on-off module to connect the connection between the BMC and the server VR chip.

[0069] Optionally, in this embodiment, the burning state of the VR chip of the server is used for the data burning progress of burning data into the VR chip of the server. Detecting the burning state of the server VR chip can be by detecting whether the running data of the server VR chip is transformed into the running data to be burned into the VR chip. When all the running data of the VR chip is transformed into the running data to be burned into the VR chip, it is determined that the burning state is that the chip burning jig ends burning the running data into the server VR chip. Or, detecting the burning state of the server VR chip can also be by detecting the interface state of the burning interface, that is, after the operation of burning data into the VR chip is completed, the chip burning jig will be pulled out of the burning interface, and then by detecting the interface state of the burning interface, it is determined whether the chip burning jig is pulled out of the burning interface, so as to determine that the burning state is that the chip burning jig ends burning the running data into the server VR chip.

[0070] Through the above steps, by detecting the burning state of the server VR chip, and then when the burning state is used to indicate that the chip jig ends burning the running data into the server VR chip, a path control signal is sent to the on-off module to realize connecting the BMC and the VR chip after burning the running data into the VR chip, so that the BMC can poll and read data from the VR chip, ensuring that the BMC can timely read the newly burned data in the VR chip.

[0071] As an alternative embodiment, detecting the interface state of the burning interface includes:

[0072] Detecting the level value in the burning interface;

[0073] Determining the interface state matching the level value.

[0074] Optionally, in this embodiment, when the chip burning jig is inserted into the burning interface, the burning interface will generate a change in the level. Then, by detecting the level value in the chip burning interface, the corresponding interface state is determined according to the level value of the burning interface.

[0075] Figure 5 It is an alternative chip burning flow chart according to an embodiment of the present application. As Figure 5 shown, it at least includes the following steps:
