FIG. 4 is a flowchart of a program upgrade method provided in an embodiment of the present application, where the embodiment is applicable to a version upgrade of a program, and the method may be performed by a program upgrade apparatus, where the program upgrade apparatus may be implemented in hardware and/or software, and in a specific embodiment, the program upgrade apparatus may be configured in an electronic device, where the electronic device includes a main control module; the storage partition of the main control module comprises an upgrade zone bit area, a backup area and an application program area. On the basis of the above embodiment, for further description after updating the identification information to the fifth preset identification, as shown in fig. 4, the method specifically includes the following steps:

S401, notifying an upper computer to send the upgrade package data from the initial position group of the upgrade package data.

The initial position is the position where the initial address storing the upgrade package data is located.

Specifically, after the application area data is erased and the update identification information is the fifth preset identification, the electronic device may begin to receive the upgrade package data to perform OTA upgrade, so that the electronic device notifies the upper computer to issue the upgrade package data from the initial position packet of the upgrade package data.

When the upper computer transmits the upgrade package data, a sub-package transmission mode is adopted, each sub-package is 132 bytes, the first three bytes are the data package attribute, the serial number and the serial number inverse code, the middle 128 bytes are the upgrade data, and the last byte is the check code.

S402, the serial port receives upgrade package data.

After the electronic equipment receives the data packetizing, every two bytes are processed into 16-bit data, each flash address can be written into 16-bit data, and eight addresses are used as a group to be written into the flash.

S403, determining whether the upgrade package data is successfully checked.

Specifically, by determining whether the upgrade package data is abnormal, if it is determined that the upgrade package data is abnormal, S404 is performed; if it is determined that the upgrade package data is not abnormal, S407 is performed.

S404, notifying the upper computer to resend the upgrade data packet.

S405, determining whether the retransmission times of the same upgrade package data are less than or equal to the preset times.

The number of retransmissions refers to the number of repeated transmissions of the same upgrade packet data, and the preset number of transmissions of the upgrade packet data may be, for example, 2 or 3, which is not limited in this embodiment.

Specifically, it is determined whether the number of retransmissions of the same upgrade package data is less than or equal to a preset number of times, and if it is determined that the number of retransmissions of the same upgrade package data is greater than the preset number of times, S406 is performed. If it is determined that the number of retransmissions of the same upgrade package data is less than or equal to the preset number of retransmissions, the step of receiving the upgrade package data according to the upgrade rule and writing the upgrade package data into the application area is performed in return, and specifically, the step S402 is performed in return.

S406, the main control module is powered down and restarted.

Specifically, if it is determined that the number of times of retransmission of the same upgrade package data is greater than the preset number of times, the chip pin of the main control module is placed at a low level, so that the main control module is powered down and restarted, and returns to the step of reading the upgrade flag bit data of the upgrade flag bit area, and determining the array information according to the upgrade flag bit data.

For example, the preset number of times is determined to be 3, and if the lower computer fails to receive a certain group of upgrade package data, the lower computer will notify the upper computer to resend the group of upgrade package data. If the verification fails for three times continuously, the reset pin of the main control chip is actively set to be at a high level, the reset output pin is at a low level, the main control module is restarted after power failure, and the main control module enters a guide mode again to carry out upgrading.

S407, notifying the upper computer to send the next group of upgrade package data.

Specifically, if it is determined that the upgrade package data is not abnormal, the upper computer is notified to send the next group of upgrade package data.

Illustratively, if it is determined that there is no abnormality in the upgrade package data, the upgrade package data is written to the application area in a group of 64 addresses (128 bytes). Further, the method comprises the steps of,

S408, determining whether the next group of upgrade package data is received within a second preset time.

The second preset time is a preset time interval for receiving the upgrade packet data, for example, may be 3 seconds, 5 seconds, or the like, which is not limited in this embodiment. The initial position is calculated specifically by dividing 128 bytes into a small group and 1024 bytes into a large group by fixing the size of the upgrade data packet used each time. For example: 128 bytes are the minimum erasing unit of the memory of the chip used currently, 128 bytes are taken as a group of transmission data, 8 groups of transmission data, namely 1024 bytes, are transmitted, and the lower computer automatically increases 8 the data of the upgrading zone bit area of the upgrading process and writes the data. When unexpected power failure occurs in the process of receiving the upgrade package data, after the lower computer is restarted, the data is sent to the upper computer, and the lower computer starts to continuously transmit the upgrade package data from the address +1.

Specifically, after informing the upper computer to issue the upgrade package data from the initial position group of the upgrade package data, determining whether the next group of upgrade package data is received within a second preset time; if it is determined that the next group of upgrade package data is not received within the second preset time, returning to execute S406, and controlling the main control module to perform power-down restarting; if it is determined that the next group of upgrade package data is received within the second preset time, S409 is performed.

For example, the second preset time is determined to be 5 seconds, the lower computer is notified to transmit the next set of upgrade package data every time the lower computer receives the set of upgrade package data, if a new set of upgrade package data is not received within 5 seconds, the reset pin of the main control chip is set to be at a high level, the reset output pin is at a low level, the main control chip is restarted after power is lost, and the main control chip enters the boot mode again to perform upgrade.

S409, circularly receiving the upgrade package data.

Specifically, if it is determined that the next group of upgrade package data is received within the second preset time, the upgrade package data is continuously and circularly received, and the upgrade package data is sequentially written into the application program area according to the address packet.

S410, reading the upgrade flag bit data of the upgrade flag bit area every time a group of upgrade packet data is successfully written, and automatically increasing the upgrade flag bit data by a fixed value.

The fixed value is a self-increment value of the preset upgrade flag bit data, which is not limited in this embodiment.

Specifically, the upgrade package data are sequentially written into the application program area according to the address group, and each time a group of upgrade package data are successfully written, the upgrade flag bit data of the upgrade flag bit area are read, and the upgrade flag bit data are automatically increased by a fixed value.

Illustratively, every 1024 bytes are written, the upgrade flag bit data of the upgrade flag bit area is read, after the upgrade flag bit data is self-increased by a fixed value of 8, the upgrade flag bit data of the upgrade flag bit area is erased, and the upgrade flag bit data value after the self-increased fixed value is written. Therefore, even if the electronic equipment has abnormal conditions (such as abnormal power failure and the like) in the process of receiving the upgrade package data, the upgrade flag bit data is read and sent to the upper computer only after the electronic equipment is controlled to restart, the upper computer can know which data package is transmitted in the previous upgrade package transmission process according to the received upgrade flag bit data, and the upper computer starts to continuously transmit the upgrade package from the address +1. Therefore, the upgrade mode enables the electronic equipment to continuously transmit the upgrade package after power failure and restarting, and does not need to receive the complete upgrade package again, so that the upgrade package transmission process is quickened, the upgrade time is saved, and the use experience of a user is improved.

S411, receiving the end frame data packet.

The end frame data packet is sent by the upper computer to inform the electronic equipment that all the upgrade packet data sending is completed.

And S412, after the fact that the whole data of the upgrade package is received is determined, the upgrade flag bit data of the upgrade flag bit area is erased, and the upgrade identification information is a sixth preset identification.

The sixth preset flag may be, for example, 0x7000, which indicates that the upgrade package data is determined to be completely received.

Specifically, after the upgrade package data are all received, the upgrade flag bit data of the upgrade flag bit area are erased, the upgrade identification information is a sixth preset identification, and the operation steps are carried out by continuing to jump to the application program area.

In a specific embodiment, optionally, after updating the identification information to the sixth preset identification and jumping to the application area for running, the method further includes: the identification information is reset to a default value.

Specifically, after the update identification information is the sixth preset identification and jumps to the application area for operation, the identification information 0x7000 is reset to the default value 0xFFFF.

The method has the advantages that after the lower computer is restarted rapidly, the lower computer enters the guide program, when the fact that the data of the on-line upgrading zone bit region indicate that the program needs to be upgraded is detected, the corresponding upgrading flow, the program rollback flow or the upgrading packet continuous transmission flow are entered according to the difference of the data of the zone bit region, and the upgrading efficiency of program upgrading and the use experience sense of a user are improved.

According to the technical scheme, after the update identification information is the fifth preset identification, the upper computer is informed to send the upgrade package data from the initial position group of the upgrade package data; the serial port receives upgrade package data; determining whether the upgrade package data is successfully checked; if the data of the upgrade package is abnormal, informing the upper computer to resend the upgrade data package; determining whether the retransmission times of the same upgrade package data are less than or equal to preset times; if the number of times of retransmitting the same upgrade package data is determined to be greater than the preset number of times, the main control module is restarted after power failure; if the number of times of retransmitting the same upgrade package data is less than or equal to the preset number of times, returning to execute the step of receiving the upgrade package data according to the upgrade rule and writing the upgrade package data into the application program area, and specifically returning to execute the serial port to receive the upgrade package data; if the upgrade package data is determined to be abnormal, informing the upper computer to inform the upper computer to send next group of upgrade package data; determining whether next group of upgrade package data is received within a second preset time; if the fact that the next group of upgrade package data is not received within the second preset time is determined, returning to the execution main control module to perform power-down restarting; if the next group of upgrade package data is received within the second preset time, circularly receiving the upgrade package data; reading the upgrade flag bit data of the upgrade flag bit area every time a group of upgrade packet data is successfully written, and automatically increasing the upgrade flag bit data by a fixed value; sending an ending instruction to a lower computer; after the update package data are completely received, the update flag bit data of the update flag bit area are erased, the update identification information is a sixth preset identification, and the operation steps are carried out by continuing to jump to the application program area. On the basis of the embodiment, after the update identification information is the fifth preset identification, the update package data is received and checked, the update package data is divided into a plurality of groups of data packages to be received, the sending times and the receiving time intervals of each group of data packages are determined, all the update package data are accurately received, the update flag bit data of the update flag bit area are erased, the new identification information is the sixth preset identification, the update package data continue to jump to the application program area to operate, the accuracy and the high efficiency of receiving the update package data are improved, and the safe operation of a lower computer and the safe use condition of a user are ensured.
