[0027] In one embodiment, Figure 1 As shown, a firmware upgrade method is provided, comprising the following steps:

[0028] S101: Detect multiple devices of the same type connected via a serial bus, and determine multiple target devices of the same type that meet a firmware upgrade condition.

[0029] Here, a serial bus is a communication interface used to transmit data between devices. Its characteristic is that data is transmitted one bit by one on a line. Common serial buses include IIC, PCI (Peripheral Component Interconnect), USB (Universal Serial Bus) and SPI (Serial Peripheral Interface), etc.

[0030] Here, the same type of devices are devices with the same firmware upgrade data when performing firmware upgrade.

[0031] Among them, the firmware upgrade conditions may include the compatibility of the firmware version, the storage space of the device, the current status of the device, the power stability, the time window, the environmental conditions, etc.

[0032] Among them, the devices connected through the serial bus are embedded devices, which may include sensors, memories, PSUs (Power Supply Units), etc.

[0033] S102: Determine a universal address and an independent address corresponding to each target device of the same type according to the multiple target devices of the same type.

[0034] Here, the universal address corresponds to the same address for each device, and the independent address corresponds to a different address for each device.

[0035] Specifically, the serial bus is IIC, and the general address is GCA (General Call Address). Exemplarily, the general address may be 00x0.

[0036] In one embodiment, Figure 2 This is a schematic diagram of the address configuration in the embodiment of the present application, such as Figure 2 As shown, when the main device is a baseboard management controller and the same type of device is a PSU of the same model, three PSU devices of the same model are connected to one IIC link of the baseboard management controller: PSU1, PSU2 and PSU3. The universal addresses of PSU1, PSU2 and PSU3 are the same, which are all 0x00. Each PSU is configured with a different PSU independent address according to its different position. The independent address of PSU1 is 0xB0, the independent address of PSU2 is 0xB2, and the independent address of PSU3 is 0xB4.

[0037] S103: Sending firmware upgrade data to the multiple target devices of the same type based on the universal address, wherein the firmware upgrade data of the multiple target devices of the same type are the same.

[0038] Specifically, the firmware upgrade data is sent once based on the universal address, and all target devices of the same type configured with the universal address independently receive and process the firmware data through the universal address.

[0039] S104: receiving firmware upgrade statuses sent by the multiple target devices of the same type based on independent addresses in sequence, and determining that firmware upgrades of the multiple target devices of the same type are completed.

[0040] Among them, the firmware upgrade status may include receiving data, integrity check, correctness check, executing upgrade, upgrade completion, upgrade failure, etc.

[0041] Here, when the firmware upgrade status of the device changes, the firmware upgrade status may be sent to the master device, or the master device may send a read instruction to the device at a preset interval to read the firmware upgrade status of the device.

[0042] It should be noted that the present application communicates with multiple devices of the same type at the same time through the universal call address mechanism of the IIC bus. By sending the firmware upgrade data once through this universal address, all devices of the same type can receive the firmware upgrade data. Through independent addresses, devices of the same type can perform status monitoring and fault-tolerant recovery on the transmission of firmware upgrade data of their respective devices.

[0043] In some specific implementations, detecting a plurality of devices of the same type connected via a serial bus and determining a plurality of target devices of the same type that meet the firmware upgrade condition includes:

[0044] Obtaining the operating status and current firmware version of the multiple devices of the same type;

[0045] According to the operating status and current firmware versions of the multiple devices of the same type, multiple target devices of the same type that meet the firmware upgrade conditions are determined, wherein the firmware upgrade conditions include being in an operating state of receiving solid-state upgrade data and the current firmware version matching the firmware upgrade data.

[0046] Here, the operating status can be idle, processing tasks, starting, stopping, fault, energy saving mode, etc.

[0047] Specifically, the running status of the device is obtained to determine whether the device can receive firmware upgrade data, the current firmware version of the device is obtained, and it is determined whether the environment of the current firmware version is compatible with the environment of the firmware upgrade data. When the device meets the running status to receive firmware upgrade data and the environment of the current firmware version of the device is compatible with the environment of the firmware upgrade data, the device meets the firmware upgrade conditions.

[0048] In this way, it can be ensured that the device can receive the firmware upgrade data and perform the firmware upgrade on the device.

[0049] In some specific implementations, after determining the universal address and the independent address corresponding to each target device of the same type according to the multiple target devices of the same type, the method further includes:

[0050] Determining a verification code of the firmware upgrade data according to the firmware upgrade data;

[0051] Based on the independent address, the identifier and the verification code of the firmware upgrade data are sent to the multiple target devices of the same type, so that the multiple target devices of the same type verify the received data according to the verification code and the identifier.

[0052] Here, the check code may be a CRC (Cyclic Redundancy Check), a parity check, a checksum, a Hamming code, a hash function, or the like.

[0053] The check code may be a check code for the entire firmware upgrade data, or a check code for each fragment after the firmware upgrade data is fragmented, or may include a check code for the entire data and a check code for each fragment.

[0054] Specifically, an identifier and a verification code are generated according to the firmware upgrade data and sent to multiple target devices of the same type, so that after receiving the data, the target devices of the same type can identify whether the received data is correct firmware upgrade data according to the identifier and the verification code.

[0055] In this way, by sending the verification code and the identifier of the firmware upgrade data to the target device of the same type, it can be ensured that the target device of the same type receives the correct firmware upgrade data.

[0056] In some specific implementations, sending the firmware upgrade data to the multiple target devices of the same type based on the universal address includes:

[0057] Determine the size of the data packet based on the transmission rate;

[0058] Dividing the firmware upgrade data into a plurality of data packets according to the size of the data packet, wherein each data packet includes the firmware upgrade data and a check code;

[0059] Based on the universal address, each data packet is sent to the multiple target devices of the same type in sequence.

[0060] Here, the data packet may also include an identifier, a command word, an offset address, a data packet length, a digital signature, a log record, version information, target device information, metadata, etc.

[0061] The transmission rate is the ideal transmission rate of the serial bus, and the actual transmission rate is obtained by removing the control data and adding the necessary delay. For example, the ideal transmission rate is 10KB / s and the actual transmission rate is 5KB / s.

[0062] Specifically, the firmware upgrade data is sent to all target devices of the same type through a universal address. Each device receives the data independently. After receiving the broadcast data packet, the device first checks the checksum to confirm the validity of the data packet. When the data packet is valid, the device reads the firmware upgrade data in the data packet and stores it in the local memory. When an erroneous data packet is received, the independent address of the target device of the same type is used to inform the master device to transmit the erroneous data packet, so that the master device can retransmit it.

[0063] For example, assuming that the size of the data packet is 74 bytes, the data packet may include the following contents, such as

[0064] As shown in Table 1:

[0065]

[0066] Table 1

[0067] Among them, BYTE 0-1 of the data packet is defined as Command, which contains the upgrade command word, BYTE2-BYTE5 of the data packet is defined as offset, which contains the offset address of the data packet in the firmware, BYTE6 of the data packet is defined as maxsize, which contains the maximum content of the data packet, BYTE7 of the data packet is defined as Realsize, which contains the data length of this data packet, BYTE8-BYTE71 of the data packet is defined as DATA, which contains 64 bytes of data, and BYTE 72-73 of the data packet is defined as Checksum, which contains the checksum of the data packet.

[0068] In this way, by dividing the firmware upgrade data into data packets, it is possible to avoid the situation where all data needs to be retransmitted once a firmware upgrade data transmission error occurs, thereby improving the efficiency of fault handling.

[0069] In some specific implementations, sequentially receiving the firmware upgrade statuses sent by the multiple target devices of the same type based on independent addresses includes:

[0070] Receiving firmware upgrade status sent by the plurality of target devices of the same type based on independent addresses, wherein the firmware upgrade status includes firmware upgrade success and firmware upgrade failure;

[0071] When the firmware upgrade status is firmware upgrade failure, determining the type of the firmware upgrade failure, wherein the type of the firmware upgrade failure includes data packet error and upgrade interruption;

[0072] When the type of the firmware upgrade failure is upgrade interruption, based on the independent address, sending a rollback instruction to the device corresponding to the upgrade interruption state, and receiving a rollback completion message returned by the device corresponding to the upgrade interruption state;

[0073] Based on the universal address, resending the firmware upgrade data to the device corresponding to the upgrade interruption state;

[0074] When the type of the firmware upgrade failure is a data packet error, determining one or more error data packets according to identifiers of the error data packets in the firmware upgrade status;

[0075] Based on the universal address, the one or more error data packets are sent to a device corresponding to the error status of the data packet.

[0076] Here, the upgrade interruption may be caused by firmware writing failure, device restart or freeze, service interruption and other problems; the rollback instruction is used to instruct the device to revert to the previous stable version.

[0077] The identifier of the error data packet may be a data packet sequence number, which is used to indicate a specific error data packet.

[0078] In one embodiment, data packet errors may also include data packet loss. After receiving all data packets, the device detects the integrity of the firmware upgrade data and finds that data packets are lost. The device sends an identifier of the lost data packet to the main device and receives the lost data packet retransmitted by the main device.

[0079] In this way, when faced with errors that may occur during concurrent firmware upgrades, there is a flexible and effective processing mechanism that can not only respond and solve problems quickly, but also ensure the stability and security of the entire system.

[0080] In some specific implementations, when the type of the firmware upgrade data transmission failure is a data packet transmission error, the method further includes:

[0081] Determine the number of transmission errors of each data packet according to the device whose firmware upgrade status is a data packet transmission error among the multiple target devices of the same type;

[0082] Determining the order of sending the data packets with transmission errors according to the number of transmission errors of the data packets;

[0083] The data packets with transmission errors are sent sequentially based on the universal address in the order of the data packets with transmission errors.

[0084] Furthermore, the order of sending the data packets may also be determined based on other factors, such as the order in which the erroneous data packets are received, the importance of the data packets, etc.

[0085] In this way, based on the universal address, a data packet with a transmission error can be sent once, and multiple devices can receive the data packet, thereby improving the efficiency of handling transmission errors.

[0086] In some embodiments, the method further comprises:

[0087] Determine the control data corresponding to each target device of the same type according to the requirements of each target device of the same type;

[0088] Based on the independent address of each target same-type device, the control data is sent to each target same-type device in turn.

[0089] Here, control data refers to data used to manage and direct device behavior, which may include commands (such as starting to receive data, stopping receiving data, verifying data, etc.), configuration settings, address information (such as the specific memory location or register address where firmware upgrade data is written), status requests, end signals, etc.

[0090] Furthermore, the control data may be burned-in.

[0091] Specifically, the control data corresponding to each target device of the same type is transmitted to each target device of the same type through the independent address of each target device of the same type.

[0092] In this way, by controlling the data, precise command of the equipment can be provided, while enhancing the stability and efficiency of the entire system.

[0093] In some embodiments, the method further comprises:

[0094] According to a preset rule, a target device of the same type holding the token is determined, and a start instruction is sent to the target device of the same type holding the token through an independent address, wherein the device holding the token is one of the multiple target devices of the same type;

[0095] According to the transmission order, the token is transmitted among multiple target devices of the same type in sequence;

[0096] Based on an independent address, receive the firmware upgrade status sent by the target device of the same type holding the token.

[0097] Here, the preset rules may be the device with the lowest address, the device with the highest address, random selection, and the like.

[0098] The order of token delivery may be determined statically, such as in ascending or descending order of addresses, or may be determined dynamically, such as based on a priority algorithm.

[0099] In this way, through token passing, multiple target devices of the same type report the firmware upgrade status one by one, which can avoid the situation where multiple target devices of the same type detect errors in the data packet at the same time and try to report to the master device through their respective independent addresses, resulting in concurrent conflicts on the bus.

[0100] In one embodiment, Figure 3 Schematic diagram of the upgrade status change in the embodiment of the present application, such as Figure 3 As shown, the upgrade status changes include: upgrade preparation, transmission request, data transmission, upgrade request, execution of upgrade, upgrade completion, and restart to take effect.

[0101] Exemplarily, the upgrade process state machine corresponding to the upgrade state change may include the following contents, such as

[0102] As shown in Table 2:

[0103]

[0104]

[0105] Table 2

[0106] Among them, the macro definition of upgrade preparation is SM_ISREADY, and its current state is: ready to enter the upgrade state, and its subsequent state is: respond to the command CMD_UPLOAD_START and enter the transfer request state; the macro definition of transfer request is SM_UPLOAD_REQUESTED, and its current state is: get the request to enter the data transmission state, pass in the file size, file checksum, allocate space, and its subsequent state is: receive uploaded data; the macro definition of data transmission is SM_UPLOADING, and its current state is: receive uploaded data, and its subsequent state is: receive data transmission completion instruction; the macro definition of upgrade request is SM_UPGRA DE_REQUESTED, its current state is: data transmission completed, file verification, and its subsequent state is: receiving upgrade instructions and upgrading; the macro definition for executing upgrade is SM_UPGRADING, its current state is: upgrading, opening a new thread for upgrading, and its subsequent state is: automatically modifying the state after the upgrade is completed; the macro definition for upgrade completion is SM_UPGRADE_END, its current state is: upgrade completed, space released, and its subsequent state is: the system can be restarted; the macro definition for restart effectiveness is SM_RESET, its current state is: passing the system AC / DC restart command, and its subsequent state is: after the system restarts, entering the next upgrade cycle.

[0107] In one embodiment, Figure 4 Schematic diagram of the upgrade process in the embodiment of the present application, such as Figure 4 As shown, the upgrade process in this application includes: an initialization phase, a data transmission phase, an upgrade execution phase and an upgrade completion phase.

[0108] Specifically, the initialization phase is used for the system to detect all devices connected to the IIC bus and initialize the devices, including configuring the devices to respond to the General Call Address command, as well as upgrade data packet size, checksum and other information, in preparation for receiving firmware upgrade data. The device status changes from upgrade preparation to transmission request status.

[0109] Specifically, the data transmission phase is used by the IIC master device to send the firmware upgrade data to all devices through GCA in packets, and each device receives the data independently and performs storage processing. The state of the device changes from the transmission request state to the data transmission state. At the same time, in order to ensure the reliability of data transmission, CRC check can be used in the data packet.

[0110] Specifically, the execution upgrade phase is used for the device to verify the incoming firmware upgrade data, such as CRC verification, after receiving the complete firmware upgrade data, to ensure the integrity of the firmware upgrade data and start the firmware upgrade operation. The execution upgrade phase may include steps such as erasing the old firmware, writing the new firmware, and verifying the new firmware. The status of the device changes from the upgrade request to the execution upgrade status.

[0111] Specifically, the upgrade completion phase is used to verify all devices after the upgrade is completed to ensure that the firmware versions are consistent. The device enters the upgrade completion state, releases the used resources, and enters the restart effective state if necessary, thus ending the entire upgrade process.

[0112] In one embodiment, Figure 5 Schematic diagram of the system architecture in the embodiment of the present application. Figure 5 As shown, the system architecture includes: an IIC master device, an IIC bus, and a slave device end.

[0113] Specifically, the IIC master device is used to manage and control the entire upgrade process, including initialization configuration, data transmission control, status monitoring, etc.

[0114] Specifically, the IIC bus is used to provide multi-device addressing capabilities and support concurrent data transmission.

[0115] Specifically, the slave device is used to independently receive and process firmware data through a general call address, and to support status reporting and fault recovery through an independent address.

[0116] It should be understood that although Figure 1-5 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-5 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0117] In one embodiment, Figure 6 As shown, a firmware upgrade device is provided, which includes: a detection module 601, which is used to detect multiple devices of the same type connected via a serial bus, and determine multiple target devices of the same type that meet the firmware upgrade conditions; a configuration module 602, which is used to determine a universal address and an independent address corresponding to each target device of the same type according to the multiple target devices of the same type; a sending module 603, which is used to send firmware upgrade data to the multiple target devices of the same type based on the universal address, wherein the firmware upgrade data of the multiple target devices of the same type are the same; a receiving module 604, which is used to sequentially receive the firmware upgrade status sent by the multiple target devices of the same type based on the independent addresses, and determine that the firmware upgrade of the multiple target devices of the same type is completed.
