[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] The specific implementation of the above concept is described below.

[0026] Please refer to Figure 1 and Figure 4An embodiment of the present invention provides an online chip upgrade method, which is applied to an online chip upgrade system. The system includes a presentation layer, a processing layer, and a driver layer. The method includes:

[0027] Step 100, based on user authority and user needs, the presentation layer is used to select a target configuration and a target operation from the user's authority configuration and operation type; the authority configuration includes configuring supported chips for upgrading, configuring supported upgrade speeds, and configuring supported online upgrade methods; the operation type includes burning firmware or reading firmware;

[0028] Step 102, using the processing layer to read the burning and reading process file corresponding to the target configuration, and parsing the burning and reading process file and the target operation to obtain the chip instruction and send it to the driver layer;

[0029] Step 104: Use the driver layer to send the chip instruction to the target chip, so that the target chip completes the online upgrade based on the chip instruction.

[0030] In this embodiment, first, configuration files are written in advance, including permission configuration files and burning and reading process files, etc. Then, when the chip needs to be upgraded online, you only need to know the user permissions and user requirements, and you can use the presentation layer to select the corresponding target configuration and target operation, and send it to the processing layer. Then, based on the processing layer, the corresponding burning and reading process files are selected and parsed to obtain chip instructions that can be recognized by the memory. Finally, the chip instructions are transmitted to the target chip through the driver layer, and the online upgrade and function verification of the target chip can be completed. It can be seen that the method of the present application can greatly shorten the upgrade process, improve development efficiency, and greatly improve operational flexibility.

[0031] In this embodiment, if Figure 4 As shown, the presentation layer communicates with the processing layer, the processing layer communicates with the driver layer, and the driver layer communicates with the chip. The presentation layer is used to receive user operations, such as configuring user operation permissions, configuring burning, reading Flash execution process, online firmware upgrade and online Flash reading, and send the received user operations to the processing layer. After receiving the user operation, the processing layer parses it into chip instructions and sends the chip instructions to the driver layer. The processing layer also returns the processing results to the presentation layer to display the execution results based on the presentation layer. The driver layer sends the chip instructions to hardware devices such as chips to enable the chip to complete the online upgrade.

[0032] Described below Figure 1 How the various steps are performed.

[0033] First, for step 100 , based on user authority and user needs, the presentation layer is used to select a target configuration and a target operation from the user's authority configuration and operation type.

[0034] The following are specific descriptions of permission configuration and operation types:

[0035] First, the permission configuration includes:

[0036] (1) Configuring chips that support upgrades, that is, chips that support upgrades. Users can configure the names of one or more chips for selection based on their authority and actual needs. This application has no limit on the number of configurable chips.

[0037] (2) Configure the supported upgrade speed, such as 20KHz, 100KHz, 400KHz, 750KHz, etc. This configuration only supports the programmers CH341T and CH347F.

[0038] (3) Configure the supported online upgrade methods, such as supporting IIC to SPI burning and DMA burning, where IIC to SPI burning speed is slow, and DMA burning is fast burning. Of course, users can also expand according to the specific burning method, and this application does not make specific restrictions.

[0039] Secondly, the operation types include burning firmware or reading firmware, among which burning firmware is used to trigger the online upgrade operation of the chip; reading firmware is used to monitor the upgrade results of the chip to adjust the upgrade process in real time based on the upgrade results. It should be noted that burning firmware and reading firmware are complete and universal upgrade / reading instructions within the system. After the initialization instructions are fully and correctly executed, this set of embedded universal upgrade instructions can run normally. Therefore, for chip upgrades, there is no need to perform special processing on the burning firmware or reading firmware instructions. Users only need to configure matching initialization instructions and end instructions according to their own needs.

[0040] In this step, since different users have different permissions and upgrade requirements, it is necessary to select specific target configurations and target operations according to user permissions and user requirements. The target configuration includes the target chip, target upgrade speed, and target upgrade method. For example, the target chip is chip A, the target upgrade speed is 20KHz, and the target upgrade method is DMA burning. The target operation is to burn the firmware, that is, to upgrade chip A.

[0041] Secondly, for step 102, the processing layer is used to read the burning and reading process file corresponding to the target configuration, and the burning and reading process file and the target operation are parsed to obtain the chip instruction and send it to the driver layer.

[0042] In this step, the burning and reading process files are configured based on the presentation layer. Different chips and different upgrade requirements correspond to different burning and reading process files, which are pre-written by engineers based on user permissions and user requirements. The burning and reading process files can be XML files, which are not specifically limited in this application. It should also be noted that before the presentation layer transmits each data to the processing layer, it is also used to determine the validity of the data. If it is valid, it is sent to the processing layer, otherwise, it is not sent.

[0043] In some implementations, the burning and reading process file includes: chip attribute information, initialization instructions before burning, and end instructions after burning is completed. Specifically as follows:

[0044] A. Chip attribute information: name, number, device address, offset address for burning / reading, default upgrade method, SPI address length (unit: byte) and the location of the Flash that needs to be upgraded.

[0045] B. Initialization instructions before burning and end instructions after burning: Both instructions communicate with the chip in the form of reading and writing registers. Related sub-instructions are written in sequence and executed in sequence to form functional logic. For example, after the read and write instructions are executed in sequence, OCM can be stopped, Flash can be deprotected, internal or external Flash functions can be set, and hardware protection effects can be increased.

[0046] In some implementations, the related sub-instructions include: read register instruction, write register instruction, compare register instruction, delay instruction, read first then write register instruction, built-in function instruction and display instruction. Each sub-instruction is explained in detail below.

[0047] a. Read register instruction: read register in bytes.

[0048] b. Write register instruction: write register in byte / bit form.

[0049] c. Compare register instruction: read the register in byte form and compare it with the target value.

[0050] d. Delay instruction: delay the system in milliseconds.

[0051] e. Read first and then write register instruction: Execute the read register instruction first, and pass the read value back to the subsequent write register instruction.

[0052] f. Built-in function instructions: When the logic of read-write related instructions is too complex and it is impossible to use sequential writing instructions to implement the function, and complex writing logic is required, the logic interface released by code writing can be performed within the system, and the logic interface can be configured in the burning and reading process files to implement the function, so as to use the built-in function command to implement specific logic.

[0053] g. Display instructions: You can combine the read register instruction and the write register instruction to generate a log of the instruction execution information.

[0054] In summary, once the target configuration and target operation are determined, the processing layer can be used to read the burning and reading process files corresponding to the target configuration, and parse the burning and reading process files and target operations to obtain chip instructions and send them to the driver layer. The specific process is as follows:

[0055] Step S1, using the processing layer to parse the target configuration, obtain the name of the target chip, the target upgrade speed and the target upgrade method;

[0056] Step S2, based on the name of the target chip, obtaining the attribute information, initialization instruction and end instruction of the target chip in the burning and reading process file;

[0057] Step S3, transmitting the attribute information of the target chip to the upgrade Flash and read Flash methods respectively;

[0058] Step S4, converting the initialization instruction and the end instruction into instructions recognizable by the chip and storing them in the memory;

[0059] Step S5, parsing the firmware burning operation or the firmware reading operation to obtain an upgrade instruction or a read instruction corresponding to the target chip;

[0060] Step S6, converting the initialization instruction, the upgrade instruction or the read instruction, and the end instruction into chip instructions in sequence according to a preset execution order, and sending the chip instructions to the driver layer.

[0061] In this embodiment, the processing layer plays the role of a data logic processing center in the entire architecture, and data distribution and encapsulation processing in the entire architecture are all completed in this module. The operation of the presentation layer is received upward, and the corresponding user operation is instantiated into a series of instructions and sent to the driver layer to complete the corresponding operation. The specific implementation process is as follows S1 to S6. Specifically: After steps S1 to S5, the memory already contains: initialization instructions, burning end instructions, and chip attribute information. In the case of permission information limitation, according to user selection, the upgrade Flash and Flash reading methods embedded in the application software already contain the attribute information of the chip. The processing layer will obtain the corresponding initialization and end instructions based on the authority and attribute information. For step S6, the initialization instructions, the internally embedded general upgrade / read instructions, and the burning end instructions are executed sequentially, and the relevant sub-instructions are converted into chip instructions after being executed sequentially.

[0062] Before sending chip instructions to the driver layer, the processing layer also includes:

[0063] Based on the format requirements of the driver layer, the chip instructions are encapsulated into a data packet in a preset format, and the data packet in the preset format is sent to the driver layer in the form of a dynamic link library called by the application software. The preset formats include CH341T, CH347F, USB and FTDI formats.

[0064] Finally, for step 104, the chip instruction is sent to the target chip by using the driver layer, so that the target chip completes the online upgrade based on the chip instruction.

[0065] In this step, after the target chip receives the chip instruction sent by the driver layer, it will automatically complete the online upgrade. At this time, the data in the memory will change accordingly. The user can trigger the read operation by clicking the read firmware icon on the graphical interface of the presentation layer, and the read result will be displayed in the graphical interface, so that the user can view the upgrade result.

[0066] From the above scheme, it can be seen that this application uses permission to manage online upgrades, sequentially executes multi-format custom upgrade instructions to form functional logic, and manages the upgrade process using XML configuration, which can quickly achieve chip online upgrade process control.

[0067] like Figure 2 , Figure 3 As shown, an embodiment of the present invention provides an online upgrade device for a chip.
