Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0055] Chip burning refers to burning firmware to the Flash memory of the chip. For example, in some related technologies, the product core (Cortex-A7, A53, etc.) is connected through the DS5 debugger JTAG interface, the project-specific DDR (onboard DDR or SIP DDR) is initialized, the FLASH device is initialized (operations such as initialization, reading and writing of the medium type are involved). Finally, the content to be burned is first stored in the DDR through the PC, and then moved to the FLASH medium through the DDR to complete a board-level burning. This scheme belongs to the conventional single-board burning method, which is widely used in various project developments, but is limited by the need to connect the DS5 debugger, which is expensive and the overall operation is relatively cumbersome, and is more suitable for single-board burning and debugging. In some other related technologies, the burner is connected to the computer PC end through the USB line and the like. From the operation, the file to be burned is read and burned to the FLASH memory of the specific interface. This method needs to be connected to the PC end to perform burning, and the efficiency is very low.

[0056] Based on this, the embodiment of the application provides a control method and device of an offline burner, electronic equipment and a storage medium, which can realize offline burning and improve the burning efficiency.

[0057] First, the offline burner of the embodiment of the application is described. Referring to Figure 1 , Figure 1 is a functional block diagram of the offline burner of the embodiment of the application. The offline burner comprises a substrate, and the substrate is provided with a control chip, a power module, an SD card slot, a UART serial port, a USB interface, an indicator light, a storage module and a plurality of flash interfaces. The storage module can be an on-board DDR or a SIPDDR. The SD card is used to install a secure digital card. The control chip is electrically connected with the power module, the secure digital card, the UART serial port, the USB interface, the indicator light, the storage module and the plurality of flash interfaces. The USB interface is used to access a USB data line, so as to be connected to a computer end. Different to-be-burned chips can be connected through the plurality of flash interfaces. The FLASH memories in the different to-be-burned chips are not the same. The FLASH memories in the to-be-burned chips can be any one or more of NAND, SPI NAND and SPI NOR. The power module is used for power supply. The UART serial port is used to connect an external device.

[0058] The secure digital card (Secure Digital Memory Card, SD) is a new generation of memory device based on semiconductor flash memory, which has the advantages of small size, fast data transmission speed, hot pluggable and the like, and is very suitable for use in the scene of the offline burner which needs portable and efficient data storage and transmission. The SD card in the offline burner usually adopts a file system format such as FAT32 or exFAT, so that the burner can recognize and read the files therein. In actual application, the user only needs to insert the SD card containing the firmware program into the offline burner, and the burner can read the files in the SD card and burn the firmware program into the target chip.

[0059] Onboard DDR(Double Data Rate Synchronous Dynamic Random Access Memory) is a memory chip directly integrated on the circuit board (such as motherboard, embedded system board, etc.), which as a key component of computer or electronic equipment, is responsible for temporarily storing data and instructions that need to be accessed quickly by the processor. Onboard DDR works synchronously with the processor, and can transmit data on both the rising and falling edges of the clock signal, which is twice the data transfer rate of single data rate memory, thus significantly improving the overall performance of the system. Onboard DDR has the characteristics of high bandwidth and low latency, which can meet the demand of modern processors for high-speed data access, and is widely used in computer, server, communication equipment, embedded system and other fields. It is usually integrated in the form of memory module on the circuit board, with a capacity ranging from several hundred megabytes to several tens of gigabytes, depending on the application scenario and demand.

[0060] SIP DDR(Systemin Package Double Data Rate Synchronous Dynamic Random Access Memory) is a DDR memory using system-level packaging technology, which integrates processor, memory (such as DDR chip) and other functional chips in one package to form a basic complete functional unit. From the implementation point of view, based on existing mature chips, different functional bare chips are integrated on a packaging substrate, for example, by stacking multiple 16Gb bare dies on the packaging substrate, breaking through the limitation of two-dimensional space, greatly improving the integration density per unit area, and then realizing different specifications of SIP DDR products such as 16GB capacity DDR4 particles.

[0061] FLASH memory is a non-volatile memory with the characteristics of electrically erasable and programmable, widely used in various electronic devices such as computers, mobile phones, digital cameras, embedded systems, etc. Its core principle is based on the floating gate transistor structure, which stores data by capturing or releasing electrons in the floating gate of the transistor, and the data can be retained for a long time even after power off.

[0062] Based on Figure 1The illustrated offline burner proposes a control method for the offline burner of the embodiment of the first aspect of the present application. The control method for the offline burner provided in the embodiment of the present application can be applied to the terminal, can be applied to the server side, and can also be software running in the terminal or the server side; the terminal and the server are communicatively connected with the control chip, thereby realizing communication interaction with the control chip, so that the control chip can execute the control method for the offline burner of the embodiment of the present application. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc.; the server side can be configured as an independent physical server, or can be configured as a server cluster or distributed system composed of multiple physical servers, and can also be configured as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms; the software can be an application that implements the control method of the offline burner, etc., but is not limited to the above forms.

[0063] The present application can be used in a variety of general-purpose or specialized computer system environments or configurations, which are communicatively connected to a control chip, thereby enabling communication interaction with the control chip, so that the control chip can execute the control method of the offline burner according to the embodiments of the present application. Examples include personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronic devices, network PCs, minicomputers, mainframe computers, and distributed computing environments including any of the above systems or devices. The present application may be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments, in which tasks are performed by remote processing devices connected via a communication network. In distributed computing environments, program modules may be located in local and remote computer storage media, including storage devices.

[0064] Reference Figure 2 , Figure 2 The control method of the offline programmer according to the embodiment of the present application is a flowchart of the steps of the control method of the offline programmer according to the embodiment of the present application, which includes but is not limited to steps S210 to S230.

[0065] Step S210, obtaining a mode instruction from the secure digital card, and determining the current execution mode based on the mode instruction;

[0066] It is worth noting that the mode indication instruction is used to indicate the current execution mode, and the mode indication instruction is pre-stored in a preset address of the secure digital card. In the execution method, the control chip obtains the mode indication instruction from the secure digital card based on the preset address, and then determines the current execution mode based on the mode indication instruction. For example, the current execution mode of the offline burner includes a burn-in mode and a read mode. The burn-in mode is used to burn the firmware stored in the secure digital card into the FLASH memory of the target chip. The read mode is used to read the firmware from the FLASH memory of the target chip and store the read firmware into the secure digital card.

[0067] In some embodiments, the mode indication instruction includes a field Flag1. When the value of Flag1 is 0, it indicates that the current execution mode is the burn-in mode. When the value of Flag1 is 1, it indicates that the current execution mode is the read mode.

[0068] In step S220, when it is detected that the current execution mode is the burn-in mode, the target burn-in indication information is obtained from the secure digital card.

[0069] In step S230, the firmware to be burned is obtained from the secure digital card based on the target burn-in indication information, and the firmware to be burned is burned into the target chip connected to the control chip.

[0070] It is worth noting that the firmware to be burned, the target burn-in indication information, and the mode indication instruction are pre-stored in the secure digital card. For example, the USB interface of the offline burner is connected to the computer through the USB data line, and the firmware to be burned, the target burn-in indication information, and the mode indication instruction are transmitted to the secure digital card through the computer. The target chip is electrically connected to the offline burner through the flash interface. In other embodiments, the secure digital card in the offline burner is connected to the computer through the card reader, so that the computer transmits the firmware to be burned, the target burn-in indication information, and the mode indication instruction to the secure digital card.

[0071] According to the control method of the offline burner, the control method first obtains the mode indication instruction from the secure digital card, determines the current execution mode based on the mode indication instruction, obtains the target burn-in indication information from the secure digital card if the current execution mode is the burn-in mode, then obtains the firmware to be burned from the secure digital card based on the target burn-in indication information, and burns the firmware to be burned into the target chip connected to the control chip. In this way, the current execution mode is automatically identified, and the firmware to be burned is automatically burned into the target chip when the current execution mode is the burn-in mode. The burn-in process does not need to be connected to a professional debugger or a computer, and the offline burn-in is realized, thereby improving the burn-in efficiency.

[0072] In some embodiments, in the process of burning the to-be-burned firmware to the target chip, the to-be-burned firmware is first transmitted to the storage module of the offline burner, and then the to-be-burned firmware is transmitted to the FLASH memory of the target chip through the storage module.

[0073] In some embodiments, referring to Figure 3 , Figure 3 FIG. 4 is a flowchart of a step after step S320 of the control method according to an embodiment of the present application. Specifically, after the to-be-analyzed firmware is acquired from the target chip based on the target reading instruction information and stored in the secure digital card, the control method according to an embodiment of the present application can further include, but is not limited to, step S410 and step S420.

[0074] Step S310, in the case where it is detected that the current execution mode is the reading mode, acquiring target reading instruction information from the secure digital card;

[0075] Step S320, based on the target reading instruction information, acquiring the to-be-analyzed firmware from the target chip and storing the to-be-analyzed firmware in the secure digital card.

[0076] It is worth noting that the target reading instruction information is pre-stored in the secure digital card. For example, the USB interface of the offline burner is connected to the computer end through the USB data line, and the target reading instruction information is transmitted to the secure digital card through the computer end. In another embodiment, the secure digital card in the offline burner is connected to the computer end through a card reader, so that the target reading instruction information is transmitted to the secure digital card through the computer end.

[0077] The control method according to an embodiment of the present application, through step S310 and step S320, in the case where the current execution mode is the reading mode, acquires the to-be-analyzed firmware from the target chip based on the target reading instruction information and stores the to-be-analyzed firmware in the secure digital card, thereby realizing the reading back function of the offline burner. Therefore, the control method according to an embodiment of the present application not only can burn the to-be-burned firmware to the target chip, but also can read back the to-be-analyzed firmware from the target chip and store the to-be-analyzed firmware in the secure digital card.

[0078] In some embodiments, in the process of acquiring the to-be-analyzed firmware from the target chip and storing the to-be-analyzed firmware in the secure digital card, the to-be-analyzed firmware is first read from the FLASH memory of the target chip and stored in the storage module of the offline burner, and then the to-be-analyzed firmware is transmitted to the secure digital card through the storage module.

[0079] In some embodiments, referring to Figure 4 , Figure 4 FIG. 4 is a flowchart of a step after step S320 of the control method according to an embodiment of the present application. Specifically, after the to-be-analyzed firmware is acquired from the target chip based on the target reading instruction information and stored in the secure digital card, the control method according to an embodiment of the present application can further include, but is not limited to, step S410 and step S420.

[0080] Step S410, in the case of detecting that the control chip is connected with the preset terminal, obtaining the firmware uploading instruction sent by the preset terminal;

[0081] Step S420, based on the firmware uploading instruction, reading the to-be-analyzed firmware from the secure digital card and transmitting the to-be-analyzed firmware to the preset terminal.

[0082] The control method of the offline burner according to the embodiment of the present application realizes, through steps S410 and S420, that when it is detected that the control chip is connected with the preset terminal, the to-be-analyzed firmware in the secure digital card is transmitted to the preset terminal, so that the preset terminal can analyze the to-be-analyzed firmware to perfect the debugging of the target chip. For example, the preset terminal is a computer, when the computer is connected with the USB interface of the offline burner through a USB data line, the computer sends a firmware uploading instruction to the control chip through the USB data, and then the control chip reads the to-be-analyzed firmware from the secure digital card and transmits the to-be-analyzed firmware to the computer.

[0083] In other embodiments, the secure digital card in the offline burner is connected with the computer end through a card reader, so that the computer end sends a firmware uploading instruction to the control chip through the card reader, and then the control chip reads the to-be-analyzed firmware from the secure digital card and transmits the to-be-analyzed firmware to the computer.

[0084] It should be noted that, in the process of reading the to-be-analyzed firmware from the secure digital card and transmitting the to-be-analyzed firmware to the preset terminal, the control chip first stores the to-be-analyzed firmware in the storage module, and then uploads the to-be-analyzed firmware to the preset terminal through the storage module. The preset terminal can also be a notebook computer, a mobile phone or other terminal device.

[0085] It is worth noting that the to-be-analyzed firmware is the firmware stored in the FLASH memory of the target chip. In the product development stage, the firmware burned into the FLASH memory needs to be iterated for many times before the product development is completed. When looking for missing points, the firmware in the FLASH memory can be read back and saved to the computer end for byte-by-byte data comparison and analysis, so as to accelerate the debugging progress and improve the efficiency.

[0086] In some embodiments, referring to Figure 5 , Figure 5 for Figure 2 a specific flowchart of step S210 in FIG. 2. The obtaining of the target burning instruction information from the secure digital card in step S210 can include but is not limited to steps S510 and S520.

[0087] Step S510, determining the flash memory model information of the target chip connected with the control chip;

[0088] Step S520, determining target burning instruction information matching the flash memory model information from the plurality of burning instruction information of the secure digital card as the target burning instruction information.

[0089] It is worth noting that the flash memory model information can be pre-stored in the secure digital card, for example, the flash memory model information includes a field Flag2, when Flag2 is 0, it indicates that the FLASH memory of the target chip is nand; when Flag2 is 1, it indicates that the FLASH memory of the target chip is SPInand; when Flag2 is 2, it indicates that the FLASH memory of the target chip is SPInor; the burning instruction information corresponding to different types of FLASH memories is different, and each type of FLASH memory corresponds to a burning instruction information, the burning instruction information includes configuration information of the FLASH memory, which is used to instruct the control chip to burn the to-be-burned firmware to the FLASH memory of the target chip. In another embodiment, when the control chip is connected with the target chip, the control chip can identify the FLASH memory of the target chip, so as to obtain the target flash memory model information.

[0090] In some embodiments, when the current execution mode is the reading mode, based on the flash memory model information, target reading instruction information matching the flash memory model information is determined from the plurality of reading instruction information of the secure digital card as the target reading instruction information. Different types of FLASH memories correspond to different reading instruction information, and each type of FLASH memory corresponds to a burning instruction information. The reading instruction information includes configuration information of the FLASH memory, which is used to instruct the control chip to read data from the FLASH memory. In another embodiment, the target reading instruction information includes a specific preset reading address, so it is not necessary to distinguish the type of the FLASH memory, and the to-be-analyzed firmware can be directly read from the FLASH memory based on the preset reading address.

[0091] The control method of the embodiment of the application can be compatible with multiple types of FLASH memories through steps S510 and S520, so that the application range of the offline burner is wider.

[0092] In some embodiments, the target burning instruction information includes a first data length, a first save address and a first burning address of the to-be-burned firmware. Referring to Figure 6 , Figure 6 For Figure 2 A specific flowchart of step S230 is shown in FIG. 6. Step S230, based on the target burning instruction information, obtaining the to-be-burned firmware from the secure digital card and burning the to-be-burned firmware to the target chip connected with the control chip, includes but is not limited to steps S610 and S620.

[0093] Step S610, obtaining the firmware to be burned from the secure digital card based on the first data length and the first storage address;

[0094] Step S620, transmitting the firmware to be burned into the first burning address of the target chip.

[0095] It is worth noting that through steps S610 to S620, the firmware to be burned is obtained from the secure digital card based on the first data length and the first storage address in the secure digital card, and then the firmware to be burned is transmitted into the first burning address of the FLASH memory of the target chip.

[0096] In some embodiments, the target burning indication information further includes the number of burnable times of the firmware to be burned; before transmitting the firmware to be burned into the first burning address of the target chip, it includes:

[0097] detecting the number of burnable times, and generating a burning stop instruction when it is detected that the number of burnable times is less than 1;

[0098] After transmitting the firmware to be burned into the first burning address of the target chip, it further includes:

[0099] decrementing the number of burnable times by 1.

[0100] It is worth noting that in the product development process, in order to avoid firmware leakage, the number of burnable times of the firmware to be burned is usually set, and when the number of burnable times is less than 1, a burning stop instruction is generated and burning is prohibited, and feedback can also be given to relevant personnel through an indicator light, for example, when the number of burnable times is less than 1, the indicator light flashes. After completing a burning operation, the number of burnable times is decremented by 1.

[0101] In some embodiments, the target reading indication information includes the second data length, the second storage address, and the second burning address of the firmware to be analyzed; referring to Figure 7 , Figure 7 for Figure 3 A specific flowchart of step S320. Step S320, obtaining the firmware to be analyzed from the target chip based on the target reading indication information, and storing the firmware to be analyzed in the secure digital card, including but not limited to steps S710 and S720.

[0102] Step S710, reading the firmware to be analyzed from the target chip based on the second burning address;
