[0088] Based on the above structure, various embodiments of a configuration information access method are proposed.

[0089] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a configuration information access method according to the present invention.

[0090] The embodiment of the present invention provides an embodiment of the configuration information access method. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in a different order than here. The configuration information access method of the present invention is applied to Bluetooth headsets, and can also be applied to devices such as smart phones, personal computers and servers. For ease of description, the execution subject is omitted below to explain each embodiment. In this embodiment, the configuration information access method includes:

[0091] Step S10, when a configuration information write request is received, the configuration information to be written corresponding to the configuration information write request is written into the RAM, and then the configuration information in the RAM is synchronized to the Flash, wherein the attribute of the RAM is configured so that the data is not updated when the power is off and restarted;

[0092] When a configuration information write request is received, the configuration information to be written corresponding to the configuration information write request is written into RAM (a volatile random access memory). Among them, the configuration information write request can be a request for writing configuration information that is sent to the product or triggered in the product by the writing device on the production line accessing the product during product production, or it can also be a request for the user terminal to send a write configuration information to the product through an APP in the user terminal that can be used to modify the product configuration information when the user uses the product. The configuration information to be written corresponding to the configuration information write request can refer to the configuration information that needs to be written to the product carried in the configuration information write request, or it can refer to the configuration information that needs to be written to the product that is sent after the configuration information write request. The properties of RAM are configured so that the data is not updated when the power is not turned off and restarted. Then, after the configuration information to be written is written into RAM, if an abnormal restart occurs and there is no time to synchronize the configuration information to Flash (a non-volatile random access memory), the configuration information in RAM is still there, so that the configuration information in RAM can be used to perform subsequent system startup operations.

[0093] It should be noted that configuration information generally includes multiple items, such as hardware version number, calibration value, etc., which are generally data that cannot be lost after the product loses power and are required when the system starts up, for example, different functions are started according to different configuration information. In this embodiment, the configuration information to be written may include all configuration information items, so that after the configuration information to be written is written into the RAM, the system can directly obtain the configuration information from the RAM to perform subsequent system startup operations.

[0094] After the configuration information to be written is written into the RAM according to the configuration information write request, the configuration information in the RAM is synchronized to the Flash. Specifically, the configuration information in the RAM can be used to overwrite the corresponding configuration information item in the Flash.

[0095] In one embodiment, Flash can be divided into a main partition and a backup area, and the configuration information in RAM can be synchronized to the main partition and backup area of ​​Flash to avoid loss or error of the configuration information of the main partition. The configuration information of the backup area can be used for recovery, thereby improving the storage reliability of the configuration information.

[0096] Step S20, when the system starts, checking whether the configuration information in the RAM is valid;

[0097] Whenever the system starts up and needs to obtain configuration information to perform subsequent system startup operations according to the configuration information, the configuration information can be obtained from the RAM first. Specifically, the configuration information in the RAM can be checked first to see if it is valid; the detection method can refer to the existing configuration information validity detection method, for example, the validity detection can be performed by detecting whether the magic number is a preset fixed value, whether the format version number is the same as the preset version number, and performing a CRC (Cyclic Redundancy Check) check on the entire data area.

[0098] Step S30, if the configuration information in the RAM is valid, the system startup operation is performed according to the configuration information in the RAM, and the configuration information in the Flash is detected to be consistent with the configuration information in the RAM;

[0099] If the configuration information in RAM is valid, the subsequent system startup operations can be performed according to the configuration information in RAM. It should be noted that, since the properties of RAM are configured so that the data is not updated when the power is not turned off and restarted, if the configuration information in RAM is valid when the system starts, it means that the system is not powered off and restarted, and the configuration information in RAM is the latest configuration information written. Therefore, the valid configuration information in RAM can be used to perform subsequent system startup operations to ensure the normal operation of system functions. If the configuration information in RAM is valid, it can be detected whether the configuration information in Flash is consistent with the configuration information in RAM. If they are consistent, it means that the latest configuration information written in RAM has been successfully synchronized to Flash. At this time, no operation is required.

[0100] Step S40: If they are inconsistent, the configuration information in the RAM is synchronized to the Flash.

[0101] If the configuration information in the Flash is inconsistent with the configuration information in the RAM, it means that before the restart, the latest configuration information written in the RAM has not been synchronized to the Flash or the configuration information synchronized to the Flash is incorrect. In this case, the configuration information in the RAM can be synchronized to the Flash so that the next time the system is restarted after power failure, the valid configuration information can be obtained from the Flash to perform subsequent system startup operations, thereby avoiding the system startup abnormality caused by the abnormal restart configuration information not being synchronized to the Flash or the configuration information synchronized to the Flash being incorrect when writing the configuration information.

[0102] In this embodiment, by configuring the RAM attribute so that the data is not updated when the power is turned off and restarted, when a configuration information write request is received, the configuration information to be written corresponding to the configuration information write request is written into the RAM, and then the configuration information in the RAM is synchronized to the Flash. When the system starts, the configuration information is first obtained from the RAM to detect whether the configuration information is valid. If it is valid, the configuration information in the RAM is used to perform subsequent system startup operations, and when the configuration information in the Flash is inconsistent with the configuration information in the RAM, the configuration information in the RAM is synchronized to the Flash. It is achieved that when an abnormal restart occurs when writing the configuration information, resulting in the configuration information not being synchronized to the Flash or the configuration information synchronized to the Flash being wrong, valid configuration information can also be obtained from the RAM to perform subsequent system startup operations, and by synchronizing the valid configuration information in the RAM to the Flash, when the system is restarted after a subsequent power outage, valid configuration information can also be obtained from the Flash to perform subsequent system startup operations, thereby ensuring the normal operation of the system functions.

[0103] Further, in one embodiment, the step of synchronizing the configuration information in the RAM to the Flash in step S10 and / or step S40 includes:

[0104] Step a, synchronizing the configuration information in the RAM to the main partition of the Flash, and then detecting whether the configuration information in the main partition of the Flash is valid;

[0105] Flash can be divided into a main partition and a backup area, and the configuration information in RAM can be synchronized to the main partition and the backup area of ​​Flash, so that when the configuration information of the main partition is lost or an error occurs, the configuration information in the backup area can be used for recovery, thereby improving the storage reliability of the configuration information. Specifically, after the configuration information to be written is written into RAM, the configuration information in RAM can be synchronized to the main partition of Flash, and then the configuration information in the main partition of Flash can be obtained to detect whether it is valid, so as to determine whether the synchronization is successful. The method for detecting the validity of the configuration information in the main partition of Flash can refer to the method for detecting the validity of the configuration information in RAM in the above embodiment, which will not be repeated here.

[0106] Step b, if the configuration information in the primary partition of the Flash is valid, synchronizing the configuration information in the RAM to the backup area of ​​the Flash;

[0107] If the configuration information in the main partition of Flash is valid, it means that the synchronization is successful, and the configuration information in RAM can be synchronized to the backup area of ​​Flash. Furthermore, after synchronization to the backup area of ​​Flash, it is also possible to detect whether the configuration information in the backup area of ​​Flash is valid. If it is invalid, a retry is performed, that is, the configuration information in RAM is synchronized to the backup area of ​​Flash again. If the synchronization is successful, no retries are performed, or if the number of retries reaches a preset upper limit, no retries are performed, and an error can be reported. Among them, the method for detecting the validity of the configuration information in the backup area of ​​Flash can refer to the method for detecting the validity of the configuration information in RAM in the above embodiment, and will not be repeated here.

[0108] Step c: if the configuration information in the main partition of the Flash is invalid, retry to synchronize the configuration information in the RAM to the main partition of the Flash.

[0109] If the configuration information in the main partition of the Flash is invalid, it means that the synchronization has failed. At this time, a retry can be performed, that is, the configuration information in the RAM is synchronized to the main partition of the Flash again. Further, after the synchronization is successful, no retries can be performed, or no retries can be performed when the number of retries reaches a preset upper limit, and an error can be reported.

[0110] In this embodiment, after writing the configuration information to be written into RAM, the configuration information in RAM is synchronized to Flash, and the configuration information in Flash is detected to see whether it is valid. If it is invalid, a retry is performed, thereby improving the reliability of the configuration information in Flash and avoiding the occurrence of system startup abnormalities due to invalid configuration information written into Flash.

[0111] Further, based on the above first embodiment, a second embodiment of the configuration information access method of the present invention is proposed. In this embodiment, when a configuration information write request is received in step S10, the step of writing the configuration information to be written corresponding to the configuration information write request into the RAM includes:

[0112] Step S101, when receiving a configuration information write request, detecting whether the configuration information in the RAM is valid;

[0113] Step S102, if the configuration information in the RAM is valid, then writing the configuration information to be written corresponding to the configuration information writing request into the RAM;

[0114] In this embodiment, the configuration information to be written may include only some configuration information items, or may include all configuration information items, depending on the writing scenario and user needs. For example, when the configuration information is written for the first time or all the configuration information needs to be updated, the configuration information to be written includes all items. When only part of the configuration information needs to be updated, the configuration information to be written may include only the items that need to be updated.

[0115] When a configuration information write request is received, the configuration information in the RAM can be checked first to see if it is valid. If the configuration information in the RAM is valid, it means that all configuration information items are included in the RAM and are valid. At this time, the configuration information to be written can be directly written into the RAM. If the configuration information to be written only includes some items, the configuration information to be written can be used to update the corresponding configuration information items in the RAM.

[0116] Step S103, if the configuration information in the RAM is invalid, read and detect whether the configuration information in the Flash is valid;

[0117] Step S104: if the configuration information in the Flash is valid, after synchronizing the configuration information in the Flash to the RAM, write the configuration information to be written corresponding to the configuration information write request into the RAM.

[0118] If the configuration information in RAM is invalid, it means that the configuration information in RAM is wrong, or it is overwritten by other data after power failure and restart. At this time, the configuration information in Flash can be read and detected whether it is valid. If the configuration information in Flash is valid, the configuration information in Flash can be synchronized to RAM first, and then the configuration information to be written can be written to RAM. It should be noted that if the configuration information to be written includes only some items, the configuration information in RAM is still invalid after the invalid configuration information in RAM is updated with some items. Synchronizing the configuration information in RAM to Flash will cause the configuration information in Flash to be invalid. Therefore, in this embodiment, when the configuration information in RAM is detected to be invalid, the valid configuration information in Flash is synchronized to RAM first, so as to ensure that the configuration information to be written is written when the configuration information in RAM is valid, thereby ensuring that the configuration information synchronized to Flash is valid, and then ensuring that the system can start normally.

[0119] It should be noted that when the configuration information to be written includes some configuration information items, after the configuration information to be written is used to update the corresponding configuration information items in the RAM, the CRC check value of the configuration information in the RAM can be recalculated and updated. After the configuration information in the RAM is synchronized to the Flash, the validity of the configuration information in the Flash is detected based on the updated information.

[0120] Further, in one embodiment, step S103 includes:

[0121] Step S1031, if the configuration information in the RAM is invalid, read and detect whether the configuration information in the main partition of the Flash is valid;

[0122] The Flash may be divided into a primary partition and a backup area. When a configuration information write request is received, if it is detected that the configuration information in the RAM is invalid, the configuration information in the primary partition of the Flash may be read and detected first to determine whether it is valid.

[0123] The step S104 includes:

[0124] Step S1041, if the configuration information in the main partition of the Flash is valid, after synchronizing the configuration information in the main partition of the Flash to the RAM, the configuration information to be written corresponding to the configuration information write request is written into the RAM;

[0125] If the configuration information in the main partition of the Flash is valid, the configuration information in the main partition of the Flash can be synchronized to the RAM first, and then the configuration information to be written can be written to the RAM to ensure that the configuration information to be written is written when the configuration information in the RAM is valid, thereby ensuring that the configuration information synchronized to the Flash is valid, and then ensuring that the system can start normally.

[0126] Step S1042, if the configuration information in the primary partition of the Flash is invalid, then read and detect whether the configuration information in the backup area of ​​the Flash is valid;

[0127] Step S1043: if the configuration information in the backup area of ​​the Flash is valid, after synchronizing the configuration information in the backup area of ​​the Flash to the RAM and the main partition of the Flash, the configuration information to be written corresponding to the configuration information write request is written into the RAM.

[0128] If the configuration information in the main partition of Flash is invalid, you can read and check whether the configuration information in the backup area of ​​Flash is valid. If the configuration information in the backup area of ​​Flash is valid, the configuration information in the backup area of ​​Flash is first synchronized to RAM and the main partition of Flash, and then the configuration information to be written is written to RAM to ensure that the configuration information to be written is written when the configuration information in RAM is valid, thereby ensuring that the configuration information synchronized to Flash is valid, and then ensuring that the system can start normally.

[0129] Furthermore, in one embodiment, after step S103, the following steps are further included:

[0130] Step S105: if the configuration information in the Flash is invalid, the configuration information in the RAM and the Flash is reset to a preset default value, and then the configuration information to be written corresponding to the configuration information write request is written into the RAM.

[0131] If the configuration information in RAM is invalid and it is detected that the configuration information in Flash is also invalid, the configuration information in RAM and Flash can be reset to the preset default values. The preset default values ​​are a set of valid configuration information pre-set in the code. Although the configuration information is not necessarily the latest, it can be guaranteed to be valid so that the system can start normally. After resetting the configuration information in RAM and Flash to the preset default values, the configuration information to be written is written to RAM, thereby avoiding the situation where the configuration information synchronized to Flash is also invalid due to the invalid configuration information in RAM when only part of the configuration information items are written. That is, it ensures that the system can start normally.

[0132] It should be noted that, when the Flash is divided into a primary partition and a backup area, the configuration information in the Flash being invalid may mean that the configuration information in both the primary partition and the backup area are invalid.

[0133] In one embodiment, when a configuration information write request is received, the following steps may be followed: Figure 3 The process steps shown write the configuration information to RAM and synchronize it to Flash.

[0134] Further, based on the first and / or second embodiments above, a third embodiment of the configuration information access method of the present invention is proposed. In this embodiment, after step S20, the method further includes:

[0135] Step S50, if the configuration information in the RAM is invalid, read and detect whether the configuration information in the Flash is valid;

[0136] When the system starts, if it is detected that the configuration information in the RAM is invalid, it means that the system may be started after a power failure, or the configuration information in the RAM is wrong. At this time, the configuration information in the Flash can be read and detected to see if it is valid.

[0137] Step S60: If the configuration information in the Flash is valid, the system startup operation is performed according to the configuration information in the Flash, and the configuration information in the Flash is synchronized to the RAM.

[0138] If the configuration information in Flash is valid, the subsequent system startup operations can be performed according to the configuration information in Flash, ensuring that the system can start and run normally. If the configuration information in Flash is valid, the configuration information in Flash can be synchronized to RAM, so that if the system does not power off and restart due to an abnormality during operation, the configuration information can be directly obtained from RAM to perform subsequent system startup operations, thereby improving the system startup speed.

[0139] Further, in one embodiment, the step S50 includes:

[0140] Step S501, if the configuration information in the RAM is invalid, then read and detect whether the configuration information in the main partition of the Flash is valid;

[0141] The Flash can be divided into a primary partition and a backup area. When the system starts, if it is detected that the configuration information in the RAM is invalid, the configuration information in the primary partition of the Flash can be read and detected first to see if it is valid.

[0142] The step S60 comprises:

[0143] Step S601, if the configuration information in the main partition of the Flash is valid, the system startup operation is performed according to the configuration information in the main partition of the Flash, and the configuration information in the main partition of the Flash is synchronized to the RAM;

[0144] If the configuration information in the main partition of Flash is valid, the system startup operation is performed according to the configuration information in the main partition of Flash to ensure that the system can start and run normally. If the configuration information in the main partition of Flash is valid, the configuration information in the main partition of Flash can also be synchronized to RAM, so that if the system is running due to an abnormality and does not power off and restart, the configuration information can be directly obtained from RAM to perform subsequent system startup operations, thereby improving the system startup speed.

[0145] Step S602: if the configuration information in the primary partition of the Flash is invalid, then read and detect whether the configuration information in the backup area of ​​the Flash is valid;

[0146] Step S603: If the configuration information in the backup area of ​​the Flash is valid, the system startup operation is performed according to the configuration information in the backup area of ​​the Flash, and the configuration information in the backup area of ​​the Flash is synchronized to the main partitions of the RAM and the Flash.

[0147] If the configuration information in the main partition of Flash is invalid, the configuration information in the backup area of ​​Flash can be read and checked to see if it is valid. If the configuration information in the backup area of ​​Flash is valid, the system startup operation can be performed according to the configuration information in the backup area of ​​Flash to ensure that the system can start and run normally. If the configuration information in the backup area of ​​Flash is valid, the configuration information in the backup area of ​​Flash can also be synchronized to RAM, so that if the system does not power off and restart due to an abnormality during operation, the configuration information can be directly obtained from RAM to quickly perform subsequent system startup operations, thereby improving the system startup speed. If the configuration information in the backup area of ​​Flash is valid, the configuration information in the backup area of ​​Flash can also be synchronized to the main partition of Flash, so that the next time the power is off and restarted, the valid configuration information can be directly obtained from the main partition of Flash to perform subsequent system startup operations.

[0148] Furthermore, in one embodiment, after step S50, the following steps are further included:

[0149] Step S60: If the configuration information in the Flash is invalid, the system startup operation is performed according to the preset default values, and the preset default values ​​are written into the RAM and the Flash as the configuration information.

[0150] If the configuration information in RAM is invalid, and it is detected that the configuration information in Flash is also invalid, the system startup operation can be performed according to the preset default values. Among them, the preset default values ​​are a set of valid configuration information pre-set in the code. Although the configuration information is not necessarily the latest, it can be guaranteed to be valid so that the system can start normally. In the case that the configuration information in RAM and Flash are both invalid, the preset default values ​​can also be written into RAM as configuration information, so that if the system operation process does not power off and restart due to an abnormality, the configuration information can be quickly obtained directly from RAM to perform subsequent system startup operations, thereby improving the system startup speed. In the case that the configuration information in RAM and Flash are both invalid, the preset default values ​​can also be written into Flash as configuration information, so that when the power is off and restarted next time, the valid configuration information can be directly obtained from Flash to perform subsequent system startup operations, thereby ensuring that the system starts normally.

[0151] It should be noted that, when the Flash is divided into a primary partition and a backup area, the configuration information in the Flash being invalid may mean that the configuration information in both the primary partition and the backup area are invalid.

[0152] In one embodiment, when it is necessary to synchronize configuration information from one of the storage areas of the main partition and the backup area of ​​the RAM and Flash to another storage area, it can be detected whether the synchronization is successful after synchronization, that is, whether the synchronized configuration information is valid. If invalid, retries are performed until the synchronization is successful and the retries are stopped, or an error is reported when the number of retries reaches the upper limit.

[0153] In one embodiment, when the system starts, the following Figure 4 The process steps shown obtain configuration information for subsequent system startup operations.
