Step 230, determining the blocking information of the target firmware according to the preset firmware protocol.
The blocking information is a range of continuously transmitting the target firmware, for example, if the target firmware data is transmitted from the master device to the target slave device through the CAN bus, the single frame data generally contains 8 bytes, so when the target firmware contains a large amount of data, the data of the target firmware needs to be split and transmitted, and one frame is transmitted at a time, and the blocking information is used for determining the number of data frames transmitted at one time, for example, 100 frames.

The target slave device determines a reply time according to the block information to return firmware receiving information at the reply time, wherein the firmware receiving information is a firmware receiving condition of a current block, for example, the firmware receiving information is receiving success or receiving failure, if the firmware receiving information is receiving failure, the firmware receiving information can also comprise a specific frame number of receiving failure, and if the block information comprises a range of continuously sending the target firmware to be 100 frames, the target slave device returns the firmware receiving information after receiving 100 frames of data, and if the 56 th frame is not receiving success or the receiving time exceeds a preset threshold, the returned firmware receiving information can comprise that the 56 th frame is not receiving successfully.
Step 250, determining the transmission mode of the next block of the target firmware according to the firmware receiving information.
If the firmware receiving information is that the receiving is successful, determining that the next block of the target firmware can be sent in a way of continuing to block from the first frame of the data frame which is not sent, and sending the block; if the firmware receiving information is a receiving failure, determining that the transmission mode of the next block of the target firmware can continue to block and transmit from the data frame with the failed transmission, and if the current block is 1-100 frames of data, and if the firmware receiving information is a receiving success, determining that the transmission mode of the next block of the target firmware is 101-200 frames of data; if the firmware receiving information is that the 56 th frame is not successfully received, the next block of the target firmware can be determined to be sent in a manner of sending 56-156 frame data.

Alternatively, the computer readable storage medium may be a machine readable signal medium. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.
To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.
The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.
