The firmware information refers to software in the component, which is used as the bottommost working in the component, for example, in a fast charging MCU in a mobile phone, and the firmware is a code for controlling charging logic. In general, when the device leaves the factory, the memory of the component may be blank, and does not contain any firmware information, and the firmware information needs to be written into the component through a specific program; in addition, in the case where firmware information in a component needs to be updated, new firmware information needs to be written into the component by a specific program to replace the old version of firmware information.
Specifically, when the processor upgrades the firmware information of the component, the processor may first send the current firmware information to the component to be upgraded. When the processor sends the current firmware information to the component to be upgraded, the current firmware information stored in the electronic device can be directly sent to the component to be upgraded, or a storage address of the current firmware information can be sent to the component to be upgraded, and the component to be upgraded is instructed to download the current firmware information from the storage address, and the sending mode is not limited herein.
The processor may send the current firmware information to the component to be upgraded through one transmission, or may send the current firmware information to the component to be upgraded in multiple times, which is not limited herein.
In addition, when the processor sends the current firmware information to the component to be upgraded, the current firmware information can be sent through an I2C bus connected between the processor and the component to be upgraded, or the information can be transferred through a register of the component to be upgraded, which is not limited herein.
After the component to be upgraded acquires the current firmware information, the current firmware information can be written into a cache area of the component to be upgraded, the component to be upgraded can write the current firmware information into the cache area one by one, and a plurality of bytes can be cached at a time according to the processing capacity of the component to be upgraded; the above-mentioned cache method is not limited herein.

The checking operation is used for checking the integrity of the information in the cache area, and the situation that the information written into the cache area by the part to be upgraded is different from the current checking information due to data transmission errors is avoided. The above-mentioned check operation may be parity check or MD5 check, and the type of the above-mentioned check operation is not limited here.
After the part to be upgraded completes the verification operation according to the instruction of the processor, a first verification result can be returned to the processor, wherein the first verification result can be a verification code obtained after the part to be upgraded performs verification calculation on the information in the cache area.
S103, based on the first check result, determining whether the information in the cache area is identical with the current firmware information.
After the processor obtains the first verification result returned by the component to be upgraded, the processor can compare the obtained verification result with the first verification result to determine whether the information in the cache area is the same as the current firmware information. Specifically, the processor may obtain the verification result before sending the current firmware information, or may perform the verification operation after receiving the first verification result, which is not limited herein.
Optionally, the processor may perform the same verification operation on the current firmware information after receiving the first verification result, to obtain a second verification result; if the first check result is the same as the second check result, the information in the cache area is determined to be the same as the current firmware information.
And S104, if the information in the cache area is the same as the current firmware information, sending a firmware upgrading instruction to the part to be upgraded.
On the basis of the above steps, if the information in the buffer area is the same as the current firmware information, the processor may determine that the current firmware information sent to the component to be upgraded is normally transmitted, and may instruct the component to be upgraded to perform firmware upgrade.
If the first checking result is different from the second checking result, the information in the cache area of the part to be upgraded is determined to be different from the current firmware information, so that the current firmware upgrading failure can be determined, or the current firmware information can be sent to the part to be upgraded again, so that the part to be upgraded writes the current firmware information into the cache area again.
After the component to be upgraded receives the firmware upgrading instruction, the current firmware information in the buffer area can be programmed into the storage area of the firmware information, and the historical firmware information in the component to be upgraded can be replaced to finish firmware upgrading.
According to the firmware upgrading method, the processor sends the current firmware information to the part to be upgraded, so that the part to be upgraded can write the current firmware information into the cache area; further, the processor instructs the part to be upgraded to execute verification operation on the information in the cache area, and a first verification result returned by the part to be upgraded is obtained; then, based on the first check result, determining whether the information in the cache area is the same as the current firmware information; and if the information in the cache area is the same as the current firmware information, sending a firmware upgrading instruction to the part to be upgraded.

Fig. 3 is a flow chart of a firmware upgrading method in an embodiment, where the embodiment relates to a manner in which a processor instructs a component to be upgraded to perform a verification operation on information in a cache area, and on the basis of the embodiment, as shown in fig. 3, the step S102 includes:
S201, based on the writing state information returned by the part to be upgraded, determining whether the part to be upgraded has completed writing operation of the current firmware information.
The writing state information may indicate whether all writing of the current firmware information is completed, or whether each piece of information in the current firmware information is completed, and the processor may determine whether firmware information which is not completed is present based on the writing completion state of each piece of information; the instruction method of the firmware information is not limited herein. For example, the component to be upgraded may write the writing state information into the state register, and when bit1 in the state register is 1, it may indicate that writing of the current firmware information is completed; in addition, the bit1 being 1 may also indicate that writing of the part of the currently cached firmware information is completed, and when the bits 1 continuously returned by the part to be upgraded are all 1, after the sending of the current firmware information is completed, the processor may determine that the part to be upgraded has completed writing of the current part information.
And S202, if so, indicating the to-be-upgraded component to execute verification operation on the information in the cache area.
After determining that the component to be upgraded has completed the write operation of the current firmware information, the processor may instruct the component to be upgraded to perform a check operation on the information in the cache region.
Optionally, the current firmware information includes at least one firmware single page information; the processor may instruct the component to be upgraded to perform a cyclic redundancy CRC check on a preset number of firmware single page information in the cache region.
Specifically, the processor may send a check instruction to the component to be upgraded, so that the component to be upgraded may perform CRC check on the first several pages of firmware single page information in the cache area according to a preset rule, and may also perform CRC check on the second several pages of firmware single page information in the cache area, where the instruction manner is not limited herein.
Optionally, the processor may write the page index of the firmware single page information to be verified into the control register of the component to be upgraded; the page index is used for indicating the part to be upgraded to carry out CRC (cyclic redundancy check) on the firmware single page information corresponding to the page index, and returning a first check result and check state information.
Specifically, the page index may be a continuous page or a discrete page, which is not limited herein. For example, the processor may instruct the component to be upgraded to verify the firmware single page information of page 1, may instruct the component to be upgraded to verify the firmware single page information of pages 3 to 7, and may instruct the component to be upgraded to verify pages 1 and 3 respectively.
The control register of the to-be-upgraded component may include a plurality of control sub-registers, the processor may write the page index into the control sub-registers for CRC check, for example, write the number of pages a required to be CRC checked into the reg_crc_len register, and the to-be-upgraded component may perform CRC calculation on the firmware single page information from page 1 to page a to obtain the CRC check code.
After the part to be upgraded completes the verification operation based on the indication, a first verification result can be returned to the processor, and the value of the state register is maintained according to the return state of the first verification result. Further, the processor may read the verification status information in the status register of the part to be upgraded every first preset time period; and if the verification state information characterizes the completion of the calculation of the first verification information, reading a first verification result in a data register of the part to be upgraded. The first preset duration may be 5ms or 10ms, which is not limited herein; the above-mentioned verification status information may be used to indicate whether the component to be upgraded has completed the calculation of the first verification result, and written into the data register, and may be represented by 1 bit or may be represented by a plurality of bits, which is not limited herein. The check state information may be that the bit 1 indicates that the first check result is calculated, or that the bit 0 indicates that the first check result is calculated, which is not limited herein.
For example, the unit to be upgraded may set the bit3 of the status register to 0 during the calculation of the CRC check, and set the bit3 of the status register to 1 after the CRC check is completed and the first check result is written into the data register reg_crc. The processor may read the value of the status register reg_state once every 5ms after sending the check indication, and if bit3 is 0, the value of reg_state is read again every 5ms, and if bit3 is 1, it indicates that the first check result has been calculated, and the first check result may be read from the reg_crc. If the processor reads the status register multiple times, each of which characterizes the first verification result, still in the calculation, the processor may stop reading the status register and stop the firmware upgrade process after a second preset time period, for example, 20 ms.
According to the firmware upgrading method, after the part to be upgraded finishes the writing operation of the current firmware information, the processor instructs the part to be upgraded to execute the verification operation, so that the part to be upgraded can finish the verification of the information in the cache area through one operation, the verification times are reduced, and the firmware upgrading efficiency is improved; further, the processor instructs the part to be upgraded to perform cyclic redundancy CRC (cyclic redundancy check) on the preset number of firmware single page information in the cache area, so that the part to be upgraded does not need to perform check calculation on all information in the cache area, the data volume of the check calculation is reduced, and the firmware upgrading efficiency is further improved.
Fig. 4 is a flow chart of a firmware upgrade method in an embodiment, which relates to a manner in which a processor sends current firmware information, based on the above embodiment, as shown in fig. 4, the above S101 includes:
S301, paging processing is carried out on the current firmware information according to the preset byte number, and at least one piece of firmware single page information is obtained.
Specifically, the preset bytes may be 128 bytes, 256 bytes, or more bytes, which is not limited herein. After the processor performs paging processing on the current firmware information according to the preset byte number, the processor can obtain the firmware single page information with the byte number being the preset byte number.
S302, respectively sending the firmware single page information to the parts to be upgraded.
Based on the above steps, the processor may send the firmware single page information to the component to be upgraded, and the manner in which the processor sends the firmware single page information to the component to be upgraded is similar to that in S101, which is not described herein.
In one transmission mode, the processor can write the firmware single page information into a data register of the part to be upgraded; then, writing a write operation instruction into a control register of the part to be upgraded; the write operation instruction is used for instructing the component to be upgraded to write the firmware single page information in the data register into the cache area. Wherein, the write operation instruction may be an instruction identifier, for example, denoted by 0x 60.
For example, when the processor sends the nth page of firmware single page information to the part to be upgraded, 256 bytes of the firmware single page information of the page may be written into the DATA register reg_data of the part to be upgraded, and then the write operation instruction 0x60 is written into the control register. The part to be upgraded can execute writing operation to 256 bytes in the data register according to the information in the data register and the control register, and write the firmware single page information into the cache area.
The to-be-upgraded component can return writing state information to the processor in the process of writing the firmware single-page information into the cache area, so that the processor can determine whether the to-be-upgraded component completes the caching operation of the firmware single-page information, and after detecting that the caching of the firmware single-page information is completed, the processor sends next firmware single-page information to the to-be-upgraded component. The writing state information may indicate the writing state of the firmware single page information by one bit, or may indicate the writing state by a plurality of bits, which is not limited herein.
For example, the unit to be upgraded may set bit0 of the status register reg_state to 1 during execution of the write operation, and set bit0 of the status register reg_state to 0 after completion of the write operation of the firmware single page information. The processor can determine whether the part to be upgraded has completed writing operation of the firmware single page information according to the value of the status register, can read the value of bit0 of the status register REG_STATE, and if bit0 is bit 1, the value of the bit is continuously read at intervals of a third preset duration (for example, 10 ms); if the read bit0 is 1, it is determined that writing of the firmware single page information is completed, and if the bit0 of the REG_STATE is 1 after multiple times of reading, for example, after exceeding a fourth preset duration (for example, 400 ms), it is determined that writing of the part to be upgraded fails. Further, the processor may send the firmware single page information to the component to be upgraded again, or may stop the firmware upgrade process.
Optionally, the processor writes the firmware single page information into the data register, and simultaneously writes the page index corresponding to the firmware single page information into the data register of the component to be upgraded. For example, when the processor sends page 5 firmware single page information, page index 5 may be written to the data register of the part to be upgraded. Specifically, the processor may write the firmware single page information and the corresponding page index into the same data register, or may write the firmware single page information and the corresponding page index into different data sub-registers, for example, two adjacent data sub-registers. For example, the processor may write 256 bytes of firmware single page information to one of the data subregisters and then write the page index to the other data subregister in 4 bytes.
When the part to be upgraded writes the firmware single-page information in the data register into the cache area, the storage position of the firmware single-page information in the cache area can be determined according to the page index. For example, the continuous storage space sram is used in the cache area to receive the firmware single page information, then the MTP memory address space is determined according to the page index corresponding to the firmware single page information, the page index is equivalent to the offset address, and when the 5 th page of firmware single page information is cached, the address of the firmware single page information in the MTP memory address space is: MTP start address +256 x 5.
According to the firmware upgrading method, the processor performs paging processing on the current firmware information, so that single-page information of each page of firmware can be respectively sent to the parts to be upgraded, the parts to be upgraded do not need to cache the information one by one, but can process the information with the preset byte number at one time, the information sending efficiency is improved, and the firmware upgrading efficiency is improved; further, the processor can determine the single-page writing state of each piece of firmware single-page information, so that the firmware single-page information of one page can be retransmitted after the transmission failure of the firmware single-page information of the other page, instead of retransmitting the current firmware information after all the current firmware information is transmitted, and the firmware upgrading efficiency is further improved.
Fig. 5 is a flow chart of a firmware upgrading method in an embodiment, where the embodiment relates to a manner in which a processor determines whether to perform firmware upgrading on a component to be upgraded, and based on the embodiment, as shown in fig. 5, before S101, the method further includes:
S401, acquiring version numbers of the historical firmware information stored in the parts to be upgraded.
In particular, the processor may determine whether to perform a firmware upgrade for the component to be upgraded by comparing the version numbers. The processor can acquire the version number of the historical firmware information stored in the part to be upgraded, and the part to be upgraded can be instructed to write the version number into the register through a version number reading instruction; the version number may also be queried in the historical firmware information by reading the historical firmware information, which is not limited herein.
Optionally, the version number of the historical firmware information is located at a preset position in the historical firmware information; the historical firmware information comprises at least one historical firmware single page information; the processor can acquire a target page index of the single-page information of the historical firmware where the version number is located, and then write the target page index and a reading operation instruction into a control register of the component; the reading operation instruction is used for indicating the part to be upgraded to return the historical firmware single page information corresponding to the target page index; and reading the version number of the historical firmware information from the historical firmware single page information corresponding to the target page index based on the preset position.
The version number of the history firmware information may be located on the first page of the history firmware information, or may be located on any page of the history firmware information, which is not limited herein. Optionally, the version number of the history firmware information is located at the last ten bytes in the last page of the history firmware information.
When the processor acquires the target page index of the single page information of the historical firmware where the version number is, the processor can determine the target page corresponding to the version number according to a preset rule, so that, for example, the page where the version number is stored in the processor; or the processor may receive, through the target page index reading instruction, the target page index sent by the component to be upgraded, which is not limited herein. Optionally, when the version number is located at a preset position in the last page of the historical firmware information, the processor may read the total number of pages of the historical firmware information stored in the status register of the component to be upgraded; the page number of the most significant page of the history firmware information is then determined as the target page index based on the total number of pages. For example, one of the data registers of the part to be upgraded may store the total PAGE number of the history firmware information, which may be reg_num_page, and the processor may learn the total PAGE number M of the history firmware information by reading the value of the data register, and then determine that the version number of the history firmware information is on the M-th PAGE of the history firmware information.
After the processor acquires the target page index, the processor can read the historical firmware single page information corresponding to the target page index. Specifically, the processor may write the target page index to the control register and the read operation instruction to the control register. The target page index and read operation instructions described above may be located in different control sub-registers. For example, the processor writes a target page index into the control sub-register 0x20 and then writes the read operation instruction 0x70 into the control sub-register 0x90 so that the part to be upgraded can write the historical firmware single page information corresponding to the target page index into the DATA register reg_data in the memory area and set the value of the status register according to the single page writing status.
Further, the processor may determine whether writing of the historical firmware single page information is completed according to the value in the status register, for example, the processor may continuously read the value of bit0 in the status register, if bit0 is 1, identify that the part to be upgraded is being written, and if bit0 is 0, indicate that writing of the historical firmware single page information is completed. If bit0 is always 1 for a period of time (e.g., 10 ms), the processor may consider the history firmware single page information writing failed and stop the firmware upgrade. After the writing of the single-page writing state information characterizing the historical firmware single-page information is completed, the processor may read the historical firmware single-page information in the data register, and then read the version number of the historical firmware information at a preset position, for example, the last ten bytes, in the historical firmware single-page information. In addition, when the part to be upgraded writes the single page information of the historical firmware, page numbers corresponding to the single page information of the historical firmware can be written into the data register at the same time, and the processor can read only the version numbers in the single page information of the historical firmware with the preset byte number. For example, the DATA register reg_data includes 256 bytes of historical firmware single page information and 4 bytes of page number information, and the processor can read the last ten bytes of the 256 bytes to obtain the version number.
And S402, when the version number of the historical firmware information is lower than that of the current firmware information, determining to upgrade the firmware information in the part to be upgraded.
When the version number of the historical firmware information is lower than the version number of the current firmware information, the processor may determine to perform firmware upgrade on the component to be upgraded. When the version number of the historical firmware information is greater than or equal to the version number of the current firmware information, the processor may determine that no firmware upgrade is required for the component.
According to the firmware upgrading method, the processor compares the version number of the historical firmware information with the version number of the current firmware information by acquiring the version number of the historical firmware information existing in the part to be upgraded to determine whether to upgrade the firmware of the part, and does not need to compare the current firmware information with the historical firmware information to determine, so that the comparison data volume is reduced, and the firmware upgrading efficiency is improved; furthermore, as the version number of the historical firmware information is located at the preset position, the processor can directly and quickly read the information at the position to obtain the version number, and the firmware upgrading efficiency is further improved.
In one embodiment, after determining to upgrade the component to be upgraded, the processor may enter the firmware upgrade mode by controlling a pin level of the component to be upgraded on the basis of the above embodiments.
After determining to upgrade the component to be upgraded, the processor can forcedly reset the component to be upgraded in a hardware reset mode before sending current firmware information to the component to be upgraded. The processor can control the pin level of the part to be upgraded so that the part to be upgraded is forcedly reset and enters a firmware upgrading mode. The control mode of the pin level is related to the pin definition of the component to be upgraded. For example, for a fast-charging MCU, the processor may pull the MCU's reset gpio pin high while pulling the clock pin low and holding for more than two seconds, then the MCU may enter a firmware upgrade mode and begin executing the firmware upgrade procedure.
According to the firmware upgrading method, the processor enables the part to be upgraded to enter the firmware upgrading mode in a pin level control mode, and compared with entering soft reset in an instruction mode, the firmware upgrading method can avoid failure of entering the upgrading mode caused by error in instruction sending, and enables firmware upgrading flow to be more stable.

S504, based on the preset position, reading the version number of the historical firmware information from the historical firmware single page information corresponding to the target page index.
S505, determining whether the version number of the historical firmware information is lower than the version number of the current firmware information, if so, executing S506, and if not, exiting the firmware upgrading process.
S506, entering a firmware upgrading mode by controlling the pin level of the component to be upgraded.
S507, paging the current firmware information according to the preset byte number to obtain at least one firmware single page information.
S508, repeatedly executing the single-page writing operation until the single-page information of each firmware is respectively sent to the parts to be upgraded.
S509, determining whether the part to be upgraded completes the writing operation of the current firmware information based on the writing state information returned by the part to be upgraded; if yes, then S510 is performed.
S510, writing the page index of the single-page information of the firmware to be verified into a control register of the component to be upgraded.
S511, reading check state information in a state register of the part to be upgraded every first preset time interval.
S512, determining whether the first check information is calculated according to the check state information, if yes, executing S513; if S513 is performed.
S513, whether the time length for reading the verification state information is longer than a second preset time length or not, if yes, exiting the firmware upgrading process, and if not, returning to S511.
S514, the same checking operation is carried out on the current firmware information, and a second checking result is obtained.
S515, determining whether the first checking result is the same as the second checking result, if so, executing S515, and if not, exiting the firmware upgrading process.
