Description

[0002] With the rapid development of the automotive industry, more and more vehicle products use embedded systems to realize their intelligent functions. Among them, automotive-grade chips serve as control units in embedded systems, and most applications are stored on the chip's flash memory. Currently, in the mass production process of automotive-grade chips, applications need to be written into the chip's flash memory by burning through a burning device.

[0003] In the prior art, when a burning device writes an application to the flash memory corresponding to the chip, the burning device needs to directly write the application code word by word, and each written data requires the burning device to initiate a write operation access to the burned chip. During the above program burning process, the write operation needs to initiate multiple accesses to the chip core. As the capacity of the written program increases, the total time required for write access to the microcontroller core will also continue to increase, resulting in low burning efficiency, affecting the production efficiency of automotive-grade embedded system products.

[0061] <Method>

[0062] Figure 1 FIG. 1 is a schematic diagram of the structure of a burning system according to an embodiment of the present disclosure. Figure 1 As shown, the programming system 1000 may include a programming device 1100 and a target chip 1200 to be programmed.

[0063] The target chip 1200 may include a first memory 1210 and a second memory 1220. The first memory 1210 is a read-only memory (ROM), and the second memory 1220 is a random access memory (RAM).

[0066] The third memory 1120 may store an operation file corresponding to the programming rule of the first memory 1210 of the target chip 1200 , and may also store data to be programmed corresponding to the target chip 1200 .

[0067] Furthermore, the operation file may be generated by the burning device 1100 according to the burning rule of the first memory 1210 of the target chip 1200 , or may be transmitted to the burning device 1100 by a host computer connected to the burning device 1100 .

[0068] Furthermore, the data to be burned can be transmitted to the burning device 1100 by a host computer connected to the burning device 1100 .

[0073] The alarm module 1170 may include a buzzer and / or an LED indicator light. The alarm module 1170 may be used to issue an alarm when the target chip 1200 fails to program data.

[0074] The present disclosure provides a data burning method for a burning device. The method can be implemented by a burning device. In one example, the burning device can be Figure 1 The burning device 1100 is shown.

[0075] Figure 2 The figure is a flow chart of a data burning method for a burning device according to an embodiment of the present disclosure.

[0076] like Figure 2 As shown, the data burning method for burning equipment may include steps S2100 to S2300 as shown below:

[0077] Step S2100, obtaining an operation file corresponding to a programming rule of a first memory of a target chip and data to be programmed corresponding to the target chip.

[0078] The operation file includes a plurality of operation programs corresponding to different functional operations. Specifically, the operation file may include at least one of the following: a burning operation program corresponding to a burning operation, an initialization operation program corresponding to an initialization operation, a deregistration operation program corresponding to a deregistration operation, an overall erasing operation program corresponding to erasing the overall data in the first memory, and a sector erasing operation program corresponding to erasing a sector of data in the first memory.

[0079] The target chip of this embodiment may be a microcontroller unit (MCU).

[0080] In this embodiment, the first memory is a read-only memory (ROM), for example, the first memory may be a flash memory.

[0081] In one embodiment, the operation file corresponding to the burning rule of the first memory of the target chip and the data to be burned corresponding to the target chip may be stored in the third memory of the burning device. When executing step S2100 of the method of this embodiment, the operation file corresponding to the burning rule of the first memory of the target chip and the data to be burned corresponding to the target chip can be directly obtained from the third memory according to the model of the target chip.

[0082] In another embodiment, when executing step S2100 of the method of this embodiment, an operation file corresponding to the burning rule of the first memory of the target chip and data to be burned corresponding to the target chip may be obtained from a host computer connected to the burning device according to the model of the target chip.

[0083] Step S2200, writing the operation file and the data to be burned into the second memory of the target chip.

[0084] The second memory is a random access memory (RAM), for example, a static random access memory (SRAM).

[0085] In one embodiment of the present disclosure, the data length of the data to be programmed may be less than or equal to the sector length of the first memory, so the operation file and the data to be programmed may be all written into the second memory of the target chip.

[0086] In another embodiment of the present disclosure, before writing the operation file and the data to be burned into the second memory of the target chip, the method may further include: splitting the data to be burned into N data blocks according to the sector length of the first memory, and obtaining a data block number representing the arrangement order of each data block in the data to be burned.

[0087] Specifically, the data block numbers may be continuous positive integers. The smaller the data block number, the earlier the corresponding data block is arranged in the data to be burned.

[0088] In this embodiment, the sector length may be determined by the model of the first memory of the target chip. The sector length may be pre-stored in the burning device, or may be input into the burning device by a user during the execution of the method of this embodiment.

[0089] On this basis, the data to be burned is written into the second memory of the target chip, including: writing some data blocks into the second memory of the target chip according to the data block number; wherein the storage space required by some data blocks is less than or equal to the storage space of the second memory; when it is detected that some data blocks currently written have been successfully burned into the first memory, determining whether there are data blocks that have not been written into the second memory; if so, continuing to execute the step of writing some data blocks into the second memory according to the data block number until the writing of all the data to be burned is completed.

[0090] In this embodiment, each partial data block written into the second memory is different, and each partial data block written may replace the partial data block in the second memory that has been successfully burned into the first memory, without modifying the operation file in the second memory.

[0091] Step S2300, controlling the target chip to perform a programming operation based on the operation file; wherein the programming operation includes: programming the program to be programmed stored in the second memory into the first memory.

[0092] In this embodiment, the burning device writes the operation file and the data to be burned into the target chip, and then controls the target chip to perform the burning operation based on the operation file, so that the target chip burns the data to be burned in the second memory into the first memory by itself. During the burning process, there is no need to access the kernel of the target chip when writing the data to be burned word by word into the target chip, and there is no need to read the burned data word by word for data verification, and the data burning process does not require the participation of the host computer. Therefore, the data burning speed and efficiency can be improved, the time consumed for burning data can be shortened, and the mass production efficiency of the controller can be improved.

[0093] In one embodiment of the present disclosure, the programming operation further includes: verifying the programmed data in the first memory based on the data to be programmed stored in the second memory, and ending the programming operation if the verification fails.

[0094] In one embodiment of the present disclosure, based on the data to be burned stored in the second memory, the burned data in the first memory is verified, including: for the data to be burned in the second memory, each time the burning of the set length data is completed, the burned data corresponding to the set length currently burned in the first memory is compared with the set length data currently burned in the second memory, if they are inconsistent, the verification fails.

[0095] The set length in this embodiment may be set in advance according to an application scenario or specific requirements. In one embodiment, the set length is smaller than the sector length of the first memory.

[0096] In a specific example, the set length may be one word (1 word, 32 bits).

[0097] Specifically, each time the target chip completes burning of one word (1 word, 32 bits) of data, it reads back the burned data of the set length currently burned in the first memory, and compares it with the data of the set length currently burned stored in the second memory. When the two are inconsistent, it means that the verification has failed, and the burning operation is terminated; when the two are consistent, it means that the verification is successful, and the burning operation continues.

[0098] Through this embodiment, the target chip verifies the burned data in the first memory based on the data to be burned stored in the second memory, without the need for the burning device to read the burned data from the first memory for verification, which can improve the data burning speed and efficiency, shorten the time consumed for burning data, and improve the mass production efficiency of the controller.

[0099] In one embodiment of the present disclosure, controlling the target chip to perform a programming operation based on an operation file includes steps S2310 to S2350 as shown below:

[0100] Step S2310, traverse N data blocks according to the data block numbers, and obtain the burning information of the currently traversed data block.

[0101] In this embodiment, the N data blocks may be traversed in the order of data block numbers from small to large.

[0102] In one embodiment of the present disclosure, before traversing the N data blocks according to the data block numbers, the method may further include: controlling the target chip to perform an initialization operation based on the operation file to unlock the first memory.

[0103] In this embodiment, data cannot be burned into the first memory without unlocking the first memory, so the first memory may be unlocked first and then the data may be burned into the first memory.

[0104] In one embodiment, controlling the target chip to perform an initialization operation based on the operation file to unlock the first memory includes: writing a second starting address of the initialization operation program in the second memory into a program counter of the target chip.

[0105] When the burning device initiates a write operation access to the register group of the target chip, the special register group of the target chip needs to be configured as the initial value. Specifically, the burning device controls the target chip to perform initialization operations based on the operation file, including: writing the second starting address of the initialization operation program to the program counter; writing the initial value to the stack pointer register, setting the stack at the unused address of the second memory of the target chip and leaving a margin for stack increase and decrease; writing 0x1000000 to the program status register, and setting the Thumb status bit to 1, indicating that the target chip can respond to the Thumb32 instruction set normally.

[0106] On this basis, the burning device further accesses the target chip and writes the key into the shutdown control and status register (DHCSR) of the target chip, so that the write operation of the target chip to the program counter takes effect. The target chip then jumps to the second starting address stored in the program counter and starts execution, that is, executes the initialization operation program.

[0107] For example, the programming device can write 0xA05F0001 into the shutdown and status register, and after writing, the shutdown and status register is read as 0x1000001, which indicates that the target chip has started running.

[0108] In another embodiment, the target chip is controlled to perform an initialization operation based on an operation file to unlock the first memory, including: writing the second starting address of the initialization operation program in the second memory into the program counter of the target chip; writing a secret key into the shutdown control and status register of the target chip, triggering the target chip to perform an initialization operation based on the written second starting address to unlock the first memory.

[0109] In yet another embodiment, controlling the target chip to perform an initialization operation based on an operation file to unlock the first memory includes: sending a first instruction to the target chip so that the target chip performs an initialization operation based on the operation file in response to the first instruction to unlock the first memory.

[0110] In an embodiment of the present disclosure, the burning device may execute steps S2310 to S2350 of this embodiment when detecting that the initialization operation is completed.

[0111] On this basis, when executing step S2200, a breakpoint instruction may also be written into the second memory of the target chip. The breakpoint instruction is used to control the target chip to trigger an interrupt when any operation program in the operation file is executed.

[0112] In some embodiments, a 4-byte 0x00BEXXXX breakpoint instruction may be written at the first address 0x20000000 of the second memory, where "XXXX" is invalid data, which is used to keep the code word-aligned. The operation file and the data to be burned are continued to be written to the second memory at the next address 0x20000004 of the breakpoint instruction.

[0113] The burning device controls the target chip to perform the initialization operation based on the operation file and further includes: writing the address of the second memory interruption point instruction into the link register.

[0114] Then, when the initialization operation program is completed, the link register jumps to the breakpoint instruction to trigger a software interrupt, so that the core of the target chip is stopped, and the stop control and status registers are written with a value indicating that the target chip has stopped running. The burning device determines whether the initialization operation program of the target chip has been completed by reading the stop control and status registers, and continues to execute subsequent processes when it is determined that the initialization operation program has been completed.

[0115] Step S2320, controlling the target chip to perform a programming operation on the currently traversed data block based on the operation file and the programming information.

[0116] In this embodiment, the data block currently traversed may be written into the second memory in advance through the above-mentioned embodiment.

[0117] In one embodiment of the present disclosure, controlling the target chip to perform a burning operation on the currently traversed data block based on the operation file and the burning information may include: writing the first starting address of the burning operation program in the second memory into the program counter of the target chip; writing the burning information into the general register of the target chip; the burning information includes the address to be burned in the first memory corresponding to the currently traversed data block, the effective length of the currently traversed data block, and the storage address of the currently traversed data block in the second memory.

[0118] Specifically, the target chip may write the burning information into the general register after writing the first starting address of the burning operation program into the program counter. For example, the address to be burned corresponding to the data block currently traversed in the first memory, the effective length of the data block currently traversed, and the storage address of the data block currently traversed in the second memory may be written into register 0, register 1, and register 2 respectively.

[0119] Furthermore, the burning device may also rewrite the address of the second memory interruption point instruction into the link register to avoid the operation program calling and changing the value of the original link register during the operation program running.

[0120] After the target chip finishes programming a word (1 word, 32 bits) of data, it reads back the data programmed in the address to be programmed and compares it with the corresponding data stored in the second memory. If the two are inconsistent, an error flag is written to register 0 and the programming process is exited. If the two are consistent, a correct flag is written to register 0 and the programming of the next word is continued until all data within the effective length of this operation are programmed. For example, the error flag can be 1 and the correct flag can be 0.

[0121] In another embodiment of the present disclosure, controlling the target chip to perform a burning operation on the currently traversed data block based on the operation file and the burning information may include: writing the first starting address of the burning operation program in the second memory into the program counter of the target chip; writing the burning information into the general register of the target chip; the burning information includes the address to be burned in the first memory corresponding to the currently traversed data block, the effective length of the currently traversed data block, and the storage address of the currently traversed data block in the second memory; writing a secret key into the shutdown control and status register of the target chip to trigger the target chip to perform a burning operation on the currently traversed data block based on the written first starting address and the burning information, so as to burn the currently traversed data block into the first memory according to the burning information.

[0122] In another embodiment of the present disclosure, controlling the target chip to perform a burning operation on the currently traversed data block based on the operation file and the burning information may include: sending a second instruction to the target chip, the second instruction carrying the burning information of the currently traversed data block; the target chip performs the burning operation on the currently traversed data block based on the operation file and the burning information in response to the second instruction.

[0123] Step S2330, when it is detected that the target chip has successfully programmed the currently traversed data block into the first memory, it is determined whether the currently traversed data block is the last data block of the data to be programmed.

[0124] The burning device can determine whether the burning operation program of the target chip has been executed by reading the shutdown control and status registers, and when the burning operation program of the target chip has been executed, read the working register 0 to verify the burning result returned by the target chip.

[0125] Specifically, when the working register 0 is a correct flag, it is determined that the target chip has burned the currently traversed data block into the first memory; when the working register 0 is an error flag, it is determined that the currently traversed data block has failed to be burned.

[0126] When it is detected that the target chip burns the currently traversed data block into the first memory, it may be determined whether the currently traversed data block is the last data block of the data to be burned, and subsequent steps are performed according to the result.

[0127] When it is detected that the currently traversed data block fails to be burned, a failure alarm can be issued. Specifically, the error message can be displayed through the display module of the burning device, or the failure alarm can be issued by controlling the buzzer to sound and / or the LED prompt light to light up, so that the target chip can be immediately troubleshooted when data burning abnormalities occur in mass production.

[0128] Through this embodiment, the target chip compares the written and read-back data to verify whether the data is burned correctly, and writes the result into register 0. The target chip then reads the working register 0 and verifies the burning result returned by the target chip. This can improve the data burning speed and efficiency, shorten the time consumed for burning data, and improve the mass production efficiency of the controller.

[0129] Step S2340: When the currently traversed data block is not the last data block, continue to execute step S2310, traverse the N data blocks according to the data block numbers, and obtain the burning information of the currently traversed data block.

[0130] Step S2350, when the currently traversed data block is the last data block, the traversal ends.

[0131] In this embodiment, the traversal may be terminated when the target chip has burned the last data block into the first memory. At this time, all the data to be burned has been burned into the first memory.

[0132] In one embodiment of the present disclosure, after executing step S2350, the method further includes: controlling the target chip to perform a logout operation based on the operation file to lock the first memory.

[0133] In one embodiment of the present disclosure, controlling the target chip to perform a deregistration operation based on an operation file to lock the first memory includes: writing a deregistration operation program at a third starting address in the second memory into a program counter of the target chip.

[0134] In another embodiment of the present disclosure, the target chip is controlled to perform a deregistration operation based on an operation file to lock the first memory, including: writing a deregistration operation program at a third starting address in the second memory into a program counter of the target chip; writing a secret key into a shutdown control and status register of the target chip to trigger the target chip to perform a deregistration operation based on the written third starting address to lock the first memory.

[0135] In another embodiment of the present disclosure, controlling the target chip to perform a logout operation based on an operation file to lock the first memory includes: sending a third instruction to the target chip, and the target chip performs a logout operation based on the operation file in response to the third instruction to lock the first memory.

[0136] In this embodiment, when the first memory is locked, a write operation cannot be performed on the first memory, thereby preventing the data burned in the first memory from being tampered with.

[0137] <Example>

[0138] Figure 3 The flowchart is an example of a method for burning data in a burning device according to an embodiment of the present disclosure.

[0139] like Figure 3 As shown, the method may include the following steps:
