The second-hand Flash materials easily cause various problems, so that the cost of research and development analysis is increased, the public praise of product brands is influenced, and enterprise loss is caused. Therefore, when the first station of the chip mounter burns the system version of the terminal through the burning tool, whether the Flash material in the terminal is a second-hand material or not is checked.
Whether a Flash material in the terminal is a second-hand material is generally checked by whether a function of a RPMB (Protected Memory Block) in an eMMC (Embedded Memory) is started or not, and since the function of the RPMB is started when a burning tool burns, a system version is considered to be burnt when the RPMB is detected to be started, namely the Flash material in the terminal is the second-hand material.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a Flash material identification method, which is applied to a burning tool and includes, as shown in fig. 1:
The terminal is provided with a Flash material, time data are stored in the Flash material, the time data comprise timing data, the initial value of the timing data is preset initial time, such as-1, 0 and the like, and the preset initial time can be set as required.
In this embodiment, when the terminal needs to be burned, the burning tool is triggered to generate a burning starting instruction, at this time, the terminal establishes a communication connection with the burning tool, the burning starting instruction is sent to the terminal by the burning tool, the terminal extracts time data from the Flash material after receiving the burning starting instruction, and then further sends the time data to the burning tool.
In practical application, the Flash material can be identified as a new material under two conditions, in the first condition, the terminal is not burned yet, namely, the burning start instruction at the time is the first burning start instruction, in this condition, because the Flash material is the new Flash material before the terminal is burned for the first time, the time data stored in the Flash material is in an un-updated state, and the timing data at the time is an initial value, namely, the initial time is preset. Therefore, when actually performing the determination, it may be determined whether the Flash material is a new Flash material according to whether the extracted timing data is the preset initial time, and when the timing data is the preset initial time, it may be determined that the Flash material is a new Flash, and the first burning of the terminal is allowed, specifically, as shown in fig. 2, after step 101 and before step 102, the method may further include:
And step 112, allowing the terminal to be burned for the first time, and updating the timing data when the terminal is burned for the first time.
It should be understood that when the timing data is determined to be the preset initial time in step 111, step 103 may be executed to determine that the Flash material is a new Flash material.
And step 113, generating new time data.
Wherein the new time data comprises updated timing data. The new timing data may be generated by a timing tool, such as a timestamp, where the timestamp is used for starting timing from the first burning of the terminal, and the timing data generated by the timing tool may replace a preset initial time.
And step 114, sending the new time data to the Flash material of the terminal.
At the moment, the burning tool writes the time data including the updated timing data into the terminal, and the terminal receives the new time data and stores the new time data in the Flash material instead of the initial time data. In a specific embodiment, the burning tool may encapsulate the new time data into a data packet in a protocol message format (e.g., a 0x96 message format) and send the data packet to the terminal, and the terminal, after receiving the data packet, parses the data packet to obtain the time data, and stores the time data in the Flash material. After that, when the burning tool is triggered again to generate the burning start instruction, the process returns to step 101 to continue to execute the process of determining whether the Flash material is a second-hand material.
In this embodiment, whether the terminal is allowed to be burned for the first time can be judged according to whether the timing data is the preset initial time, the Flash material can be confirmed to be a new Flash material while the terminal is judged to be burned for the first time, meanwhile, the timing function of the timing data can be started, and the Flash secondary material can be continuously judged by sending the new time data including the updated timing data to the terminal and receiving the time data including the continuously updated timing data in the subsequent burning process.
In the second case, the terminal has already been burned, that is, the burning start instruction at this time is a non-first burning start instruction, in this case, a software version of the system needs to be updated, for example, a problem of writing a google key (google key) on a main board of the terminal may exist due to a defect of a software system of the produced terminal, but at this time, the system is not a hardware problem of the Flash material, in order to avoid misjudging the new Flash material as the second-hand Flash material in the prior art by means of RPMB, in this embodiment, it is determined whether the Flash material in this case is the second-hand Flash material through step 102. It should be understood that, in this case, after step 101, step 111 may be executed to determine whether the timing data is the preset initial time, but at this time, the determination result of step 111 is no, and thus step 102 will be executed continuously.
And 103, judging the Flash material to be a new Flash material.
After the Flash material is determined to be a new Flash material, the subsequent production process can be continued, if the terminal can be subjected to burning, if the burning tool is triggered again to generate a burning starting instruction in the subsequent process, the step 101 is returned again to extract the time data in the Flash material, and it should be understood that the timing data in the time data continuously keeps a real-time updating state after the first burning.
And 104, judging the Flash material to be a second-hand Flash material.
After the Flash material is determined to be the second-hand material, the prompt message can be sent to prevent the follow-up production flow from being carried out.
In the embodiment, whether the Flash material is the second-hand Flash material or not can be judged according to the time length recorded by the timing data, so that the situation that the new Flash material without hardware defects is judged as the second-hand Flash material by mistake due to repeated burning caused by the defects of system software is avoided.
Optionally, the time data in this embodiment may further include a time identifier, where the time identifier is used to represent a writer of the time data, and after step 101, in the first case, that is, the terminal has not been burned, at this time, the time data stored in the Flash material is in an un-updated state, and the time identifier at this time is an initial value, that is, the initial identifier is preset. Therefore, when actually performing the determination, it may be determined whether the Flash material is a new Flash material according to whether the extracted time identifier is the preset initial identifier, and when the time identifier is the preset initial identifier, it may be determined that the Flash material is a new Flash, and the first burning of the terminal is allowed, specifically, as shown in fig. 3, after step 101 and before step 102, the method may further include:
And step 122, updating the value of the time identifier to the value of the target identifier.
And step 112, allowing the terminal to be burned for the first time, and updating the timing data when the terminal is burned for the first time.
And step 113, generating new time data.
At this time, the new time data includes the updated time stamp and the updated time count data.
And step 114, sending the new time data to the Flash material of the terminal.
In this embodiment, only step 111 may be executed to determine whether the currently required recording is the first recording, only step 121 may be executed to determine whether the currently required recording is the first recording, and also step 111 and step 121 may be executed simultaneously to determine whether the currently required recording is the first recording, when only step 111 is executed to determine, step 112 and step 113 need to be further executed to complete the update of the timing data, when only step 121 is executed to determine, step 121 and step 114 need to be further executed to complete the update of the timing data, when both steps 111 and step 121 are executed to determine, when the determination results of steps 111 and 121 are yes, the currently required recording is the first recording, and step 121 to step 114 need to be further executed to complete the update of the timing data.
In this embodiment, whether the terminal is allowed to be burned for the first time may be further determined according to whether the time identifier is the preset initial identifier, and the Flash may be determined as a new Flash material while it is determined that the terminal is burned for the first time.
In the second case, the terminal has been burned, that is, the determination result in step 121 is no, at this time, the following steps are executed:
The target identification is used for representing a target writer, and when the time identification is matched with the target identification, the time identification can be confirmed to be legal data written by the target writer, so that whether the Flash material is a second-hand Flash material can be judged according to the recorded frequent time of the timing data. However, when the time identifier is not legal data written by the target writer, even if the timing data records the time value at the moment, the time value at the moment is illegal and unreliable data, so that in order to avoid misjudgment of the second-hand Flash material, whether the Flash material is the second-hand Flash material cannot be judged through the timing data at the moment, and as an alternative, at the moment, whether the Flash material is the second-hand Flash material can be judged through the RPMB so as to ensure the functional integrity of the identification method of the Flash material in the embodiment.
It should be understood that the above methods in this embodiment are all established on the basis that the burning tool supports reading and writing time data, but for some old versions of burning tools, because the old versions of burning tools do not support the reading and writing function of time data, in this case, RPMB may also be used as an alternative scheme to determine whether the Flash material is a second-hand Flash material to ensure the functional integrity of the identification method of the Flash material in this embodiment.
In this embodiment, the step of determining whether the Flash material is a second-hand material according to the RPMB specifically may include: judging whether the RPMB function of the terminal is opened: if not, go to step 103, and if yes, go to step 104.
Optionally, in step 102, if it is determined that the timing data is within the preset time range: the identification method may further include: and checking whether the time data is complete, executing a step 103 to judge that the Flash material is a new Flash material when the checking result is complete, and executing a step 104 to judge that the Flash material is a second-hand Flash material when the checking result is incomplete. Specific checking methods can adopt mature algorithms used for checking whether data are complete, such as Crc (cyclic redundancy check algorithm), Lrc (longitudinal redundancy check algorithm), BCC (block check word element algorithm) and the like.
Example 2
The embodiment provides an identification method of a Flash material, which is applied to a terminal, wherein the Flash material is arranged in the terminal, and the identification method comprises the following steps:
and extracting time data from the Flash material and sending the time data to a burning tool, wherein the time data comprises timing data, the timing data is used for indicating the time from the first burning of the terminal to the current time, and the time data is used for judging whether the Flash material is a second-hand material or not by the burning tool.
When the terminal needs to be burned, the burning tool can generate a burning starting instruction and send the burning starting instruction to the terminal, and after the terminal receives the burning starting instruction, the terminal extracts time data in the Flash material and sends the time data to the burning tool.
In practical application, the Flash material can be identified as a new material under two conditions, in the first condition, the terminal is not burned, at the moment, the timing data is an initial value, namely, the initial time is preset, and in this condition, the time data sent to the burning tool is the time data with the specific value being the preset initial time. The burning tool can execute step 101 in embodiment 1 to receive the time data, and can determine whether burning is allowed or not, determine whether Flash is a new Flash material or not according to steps 111 to 114, generate new time data in the process of first burning, and send the new time data to the terminal.
Correspondingly, when the terminal is subjected to first burning, the terminal can receive new time data including the updated timing data and write the new time data into the Flash material.
The second case is that the terminal has been burned, in this case, after receiving the burning start instruction, the terminal will also send the time data in the Flash material to the burning tool, because the timing data in the time data starts to be timed when the terminal is burned for the first time, the timing data records the time length from the first burning to the current time, and after the terminal sends the data to the burning tool, the burning tool can judge whether the Flash material is a second-hand material according to the steps 101-102 in the embodiment 1.
Optionally, the time data in this embodiment may further include a time identifier, where the time identifier is used to characterize a writer of the time data, so that the burning tool may determine whether the time data matches with a target identifier used to characterize a target writer.
In the first case, the terminal is not burned, the time identifier is an initial value, i.e., a preset time identifier, and in this case, the time data sent to the burning tool includes the time data with a specific value of the preset time identifier.
After receiving the time data in step 101, the burning tool may determine that the time identifier is the preset initial identifier in step 121, update the value of the time identifier to the value of the target identifier in step 122, and update the timing data when burning the terminal for the first time in step 112. And transmits the time data including the updated time stamp to the Flash material of the terminal through step 123. And the terminal receives the new time data and stores the new time data into the Flash material.
In the second case, after the terminal is burned, the terminal also sends the time data in the Flash material to the burning tool after receiving the burning start instruction, because the identification data in the time data is set as the target time identification in the process of burning the terminal for the first time, the timing data in the time data records the time length from the first burning to the current time, and after the terminal sends the time data to the burning tool, the burning tool can continuously judge whether the Flash material is the second-hand material according to the steps 101 to 102 in the embodiment 1.
In the embodiment, when a burning starting instruction sent by the burning tool is received, the terminal extracts the time data from the Flash material and sends the time data to the burning tool, so that the burning tool can judge whether the Flash material is a second-hand material according to the time data, the time data can be updated when the burning tool burns the terminal for the first time, the new time data is written into the Flash material of the terminal, and when repeated burning is carried out in the same secondary production process, the time data can be extracted from the Flash material again to be identified, so that the new Flash material is prevented from being mistakenly judged as the second-hand Flash material.
Example 3
The embodiment provides an identification system of Flash materials, which is applied to a burning tool, and as shown in fig. 4, the identification system includes: a time data extraction module 301 and a timing data judgment module 302.
The time data extraction module 301 is configured to extract time data of a Flash material from a terminal, where the Flash material is disposed in the terminal, the time data includes timing data, and the timing data is used to indicate a time length from when the terminal is first burned to the current time. The terminal is provided with a Flash material, time data are stored in the Flash material, the time data comprise timing data, the initial value of the timing data is preset initial time, such as-1, 0 and the like, and the preset initial time can be set as required.
In this embodiment, when the terminal needs to be burned, the burning tool is triggered to generate a burning start instruction, at this time, the terminal device establishes a communication connection with the burning tool, the burning tool sends the burning start instruction to the terminal, the terminal extracts time data from the Flash material after receiving the burning start instruction, and further sends the time data to the burning tool, in a specific implementation manner, the terminal may package the time data into a data packet in a number 0x96 message format and send the data packet to the burning tool, and the time data extraction module 301 analyzes the data packet after receiving the data packet, so as to obtain the time data.
In practical application, the Flash material can be identified as a new material under two conditions, in the first condition, the terminal is not burned yet, namely, the burning start instruction at the moment is the first burning start instruction, in this condition, because the Flash material is the new Flash material before the terminal is burned for the first time, the time data stored in the Flash material is in an un-updated state, and the timing data at the moment is an initial value, namely, the initial time is preset. Therefore, when the judgment is actually carried out, whether the Flash material is the new Flash material can be determined according to whether the extracted timing data is the preset initial time, and when the timing data is the preset initial time, the Flash material can be determined to be the new Flash, so that the terminal is allowed to be burned for the first time.
Specifically, the identification system further includes an initial time determining module 303, a burning permission module 304, a timing data updating module 305, a time data updating module 306, and a first time data sending module 307;
the time data extraction module 301 further uses a calling initial time judgment module 303, the initial time judgment module 303 is used for judging whether the timing data is a preset initial time, if not, the time data judgment module is called, if yes, the burning permission module 304 is called, the burning permission module 304 is used for allowing the terminal to be burned for the first time, the timing data updating module 305 is used for updating the timing data when the terminal is burned for the first time, the time data updating module 306 is used for generating new time data, the new time data comprises updated timing data, and the first time data sending module 307 is used for sending the new time data to a Flash material of the terminal.
At this time, the first time data sending module 307 writes the time data including the updated timing data into the terminal, and the terminal receives the new time data and stores the new time data in the Flash material instead of the initial time data. In a specific implementation manner, the first time data sending module 307 may encapsulate new time data into a data packet in a protocol message (for example, in a message format of 0x 96), and send the data packet to the terminal, and after receiving the data packet, the terminal parses the data packet so as to obtain time data, and stores the time data in the Flash material. After that, when the burning tool is triggered again to generate a burning starting instruction, the time data extraction module 301 and the timely data judgment module are continuously called to judge whether the Flash material is a second-hand material.
In this embodiment, the initial time determining module 303 may determine whether to allow the terminal to be subjected to the first burning according to whether the timing data is the preset initial time, and may determine that the Flash material is the new Flash material while determining that the Flash material is subjected to the first burning, and may start a timing function of the timing data, and send the new time data including the updated timing data to the terminal through the first time data sending module 307, and may continue to determine the Flash secondary material by receiving the time data including the continuously updated timing data through the time data extracting module 301 in a subsequent burning process.
In the second case, the terminal has already been burned at this time, that is, the burning start instruction at this time is a non-first burning start instruction, in this case, a software system of the produced terminal may have a defect, for example, a problem of writing a google key occurs on a main board of the terminal, and a system software version needs to be updated, but at this time, the problem is not a hardware problem of the Flash material itself, so as to avoid misjudging a new Flash material as a second-hand Flash material in the prior art by means of an RPMB, in this embodiment, the timing data determination module 302 is used to determine whether the Flash material in this case is a second-hand Flash material. It should be understood that in this case, the time data extracting module 301 may still call the initial time determining module 303 to determine whether the timing data is the preset initial time, but at this time, if the determination result is no, the initial time determining module 303 will continue to call the timing data determining module 302.
The timing data determining module 302 is configured to determine whether the timing data is within a preset time range: if so, judging the Flash material to be a new Flash material, and if not, judging the Flash material to be a second-hand Flash material.
Since the second-hand Flash material is a reusable hardware device, the service time of the second-hand Flash material far exceeds that of the new Flash material, in this embodiment, whether the Flash material in the terminal is the second-hand Flash material can be judged according to whether the timing data is in the preset time range.
In a specific embodiment, the identification system may further include a time range presetting module 308, configured to generate a preset time range according to a production duration of one production for the terminal, that is, the preset time range is set not to exceed the production duration of one production for the terminal. Under normal conditions, the repeated burning of the system version cannot exceed the production time of one-time production, but because the first burning of the second-hand Flash material is not completed in the production process, the timing data in the second-hand Flash material generally exceeds the production time of one-time production, in this embodiment, the time range presetting module 308 sets the preset time range according to the production time of one-time production, so that the effect of distinguishing the second-hand Flash material from the new Flash material can be achieved.
In this embodiment, after determining that the Flash material is a new Flash material, the timing data determining module 302 may continue to perform a subsequent production process, for example, perform burning on the terminal, and subsequently, if the burning tool is triggered again to generate a burning start instruction, the time data extracting module 301 may be called again to extract the time data in the Flash material, it should be understood that the timing data in the time data continuously maintains a real-time updated state after the first burning. And the timing data judgment module 302 can send prompt information to prevent the subsequent production flow from proceeding after determining that the Flash material is the second-hand material.
In this embodiment, the timing data determining module 302 may determine whether the Flash material is a second-hand Flash material according to the timing data record, so as to avoid that a new Flash material without hardware defects is determined as the second-hand Flash material by mistake due to repeated burning caused by defects of system software.
Optionally, the time data in this embodiment may further include a time identifier, where the time identifier is used to represent a writer of the time data, and in the first case, that is, the terminal is not burned yet, at this time, the time data stored in the Flash material is in an un-updated state, and the time identifier at this time is an initial value, that is, the initial identifier is preset. Therefore, when the judgment is actually carried out, whether the Flash material is a new Flash material can be determined according to whether the extracted time identifier is the preset initial identifier, and when the time identifier is the preset initial identifier, the Flash material can be confirmed to be a new Flash, so that the terminal is allowed to be burned for the first time.
Specifically, the recognition system further includes an initial identifier determining module 309 and a target identifier updating module 310. The time data extraction module 301 is further configured to invoke an initial identifier determination module 309, where the initial identifier determination module 309 is configured to determine whether the time identifier is a preset initial identifier: if not, calling the target identification matching module, and if so, calling the target identification updating module 310;
the target identifier updating module 310 is configured to update the value of the time identifier to be the value of the target identifier, and invoke the burning permission module 304; the burning permission module 304 is configured to allow the terminal to be burned for the first time, and call the timing data update module 305, the timing data update module 305 is configured to update the timing data when the terminal is burned for the first time, the time data update module 306 is configured to generate new time data, the new time data includes an updated time identifier and updated timing data, and the first time data sending module 307 is configured to send the new time data to a Flash material of the terminal.
In this embodiment, the time data extraction module 301 may only call the initial time judgment module 303 to judge whether the current burning needs to be performed is the first burning, may only call the initial identifier judgment module 309 to judge whether the current burning needs to be performed is the first burning, and may also call the initial time judgment module 303 and the initial identifier judgment module 309 to judge whether the current burning needs to be performed is the first burning.
In this embodiment, the initial time determining module 303 and the initial identifier determining module 309 may further determine whether to allow the terminal to be subjected to the first burning according to whether the time identifier is a preset initial identifier, and may determine that Flash is a new Flash material while determining that the Flash is subjected to the first burning.
In the second case, the terminal has been burned, that is, the initial identifier determining module 309 determines whether the time identifier is the preset initial identifier, if not, the initial identifier determining module 309 is further configured to invoke a target identifier matching module, and the target identifier matching module is configured to determine whether the time identifier matches the target identifier: if yes, the timing data determination module 302 is called, otherwise, the RPMB determination module 311 is called.
The target identifier represents a target writer, and when the target identifier determination module determines that the time identifier matches the target identifier, the target identifier determination module can determine that the time identifier is legal data written by the target writer, so that the timing data determination module 302 can determine whether the Flash material is a second-hand Flash material according to the recorded time of the timing data. However, when the time identifier is not legal data written by the target writer, even if the time value is recorded in the timing data at this time, the time value at this time is illegal and unreliable data, and in order to avoid misjudgment on the second-hand Flash material, it cannot be judged whether the Flash material is the second-hand Flash material at this time through the timing data.
It should be understood that the above systems in this embodiment are all established on the basis that the burning tool supports reading and writing time data, but for some old versions of burning tools, because the old versions of burning tools do not support the reading and writing function of time data, in this case, the RPMB determining module 311 may also be called to determine whether the Flash material is a second-hand Flash material by using RPMB as an alternative to ensure the integrity of the function of the Flash material identification system in this embodiment. Specifically, the RPMB determining module 311 is configured to determine whether the RPMB function of the terminal is turned on: if not, the timing data judgment module 302 is called to judge that the Flash material is a new Flash material, and if so, the timing data judgment module 302 is called to judge that the Flash material is a second-hand Flash material.
Optionally, the identification system further includes a checking module 312, the timing data determining module 302 is further configured to invoke the checking module 312 when a determination result of determining whether the timing data is located within the preset time range is yes, and the checking module 312 is configured to check whether the time data is complete: if yes, the timing data judgment module 302 is called to judge the Flash material as a new Flash material. The specific verification method of the verification module 312 may adopt a mature algorithm such as Crc, Lrc, BCC, etc. for verifying whether the data is complete, and in this embodiment, the integrity of the time data is verified, so that the time data is prevented from being maliciously tampered, thereby affecting the accurate identification of the second-hand Flash material.

When the terminal needs to be burned, the burning tool can generate a burning starting instruction and send the burning starting instruction to the terminal, and after the terminal receives the burning starting instruction, the terminal extracts time data in the Flash material and sends the time data to the burning tool.
In practical application, in two cases, the Flash material is identified as a new material, in the first case, the terminal is not burned, at this time, the timing data is an initial value, that is, the initial time is preset, and in this case, the time data sent to the burning tool by the second time data sending module 401 is the time data including the specific value of the initial time. The burning tool may call the time data extraction module 301 in embodiment 3 to receive the time data, and may determine whether burning is allowed or not and whether Flash is a new Flash material according to the initial time determination module 303 and the burning permission module 304, generate new time data in the process of first burning through the timing data update module 305 and the time data update module 306, and send the new time data to the terminal through the first time data sending module 307.
Correspondingly, when the terminal is burned for the first time, the terminal receives new time data including updated timing data through the time data receiving module 402, and writes the new time data into the Flash material.
In the second case, after the terminal is burned at the moment, after a burning start instruction is received, the terminal can also send the time data in the Flash material to the burning tool through the second time data sending module 401, because the timing data in the time data starts to time when the terminal is burned for the first time, the timing data records the time from the first burning to the current time, and after the terminal sends the data to the burning tool, the burning tool can judge whether the Flash material is the second-hand Flash material according to the received time data.
Optionally, the time data in this embodiment may further include a time identifier, where the time identifier is used to characterize a writer of the time data, so that the burning tool may determine whether the time identifier matches a target identifier used to characterize a target writer.

And the time data including the updated time identification is transmitted to the Flash material of the terminal through the first time data transmission module 307. The terminal receives new time data through the time data receiving module 402 and stores the new time data into the Flash material.
In the second case, after the terminal is burned, the terminal also sends the time data in the Flash material to the burning tool through the second time data sending module 401 after receiving the burning start instruction, because the identification data in the time data is set as the target time identification in the process of burning the terminal for the first time, the timing data in the time data records the time from the burning for the first time to the current time, and after the second time data sending module 401 sends the time data to the burning tool, the burning tool can continue to judge whether the Flash material is the second-hand material according to the identification system in embodiment 3.
In the embodiment, when a burning starting instruction sent by the burning tool is received, the time data sending module extracts time data from the Flash material and sends the time data to the burning tool, so that the burning tool can judge whether the Flash material is a second-hand material according to the time data, the time data can be updated when the burning tool burns the terminal for the first time, new time data is written into the Flash material of the terminal, and when repeated burning is carried out in the same secondary production process, the time data can be extracted from the Flash material again to be identified, so that the new Flash material is prevented from being judged as the second-hand Flash material by mistake.
