[ Background Art ]

In the production line upgrading process of embedded equipment such as computers, mobile phones and cameras, unexpected disconnection of a communication port and interruption of upgrade file downloading caused by power failure of upgrading equipment can occur. In the prior art, when a production line is upgraded, an upgrade file is often split into a plurality of small data packets by an upper computer device, and the small data packets are sent to equipment to be upgraded in units of the data packets.

[ Detailed description ] of the invention

For a better understanding of the technical solutions of the present specification, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.

It should be understood that the described embodiments are only some, but not all, of the embodiments of the present description. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present invention based on the embodiments herein.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In the embodiment of the invention, the data packet identification information and the partition identification information of the upgrading data packet which is being downloaded are recorded, and the recorded data packet identification information and partition identification information are used as the interrupt point record information to be sent to the upper computer equipment after the system is restarted, so that the upper computer equipment continuously transmits the upgrading data packet from the interrupt point position, and the time cost waste caused by retransmission of the whole packet is avoided.

Fig. 1 is a flowchart of a breakpoint resume method according to an embodiment of the present invention. As shown in fig. 1, the method includes:

And step 101, when the equipment to be upgraded detects the restarting of the system, determining whether the system file is complete. Optionally, the device to be upgraded and the upper computer device can be connected in a wired manner or a wireless manner. Such as data lines, local area networks, wiFi, etc. When the equipment to be upgraded executes the system upgrade of the current system version for the first time, the upper computer instructs the equipment to be upgraded to erase the target system file, and before the upgrade is completed, the target system file is still in an erased state, so that the equipment to be upgraded determines whether the cause of the restarting is abnormal in the upgrading process by determining whether the system file is complete or not.

Specifically, before the equipment to be upgraded is upgraded, the upper computer equipment needs to analyze an upgrade file to obtain a plurality of upgrade data packets, wherein the upgrade file is used for upgrading the system of the equipment to be upgraded. And then determining the data packet sequence according to the plurality of upgrading data packets. For example, if the upgrade file is an image file, the upper computer device analyzes the image file and the partition description file to obtain a plurality of packet packets, and generates a fixed data packet sequence. And then, the upper computer equipment sends an upgrade instruction to the equipment to be upgraded, wherein the upgrade instruction comprises a target system file erasing instruction. The equipment to be upgraded receives an upgrade instruction sent by the upper computer equipment, wherein the upgrade instruction comprises a target system file erasing instruction. And the equipment to be upgraded erases the target system file according to the target system file erasing instruction. And then, the upper computer equipment sequentially sends a plurality of upgrading data packets to the equipment to be upgraded according to the data packet sequence. Thereby starting to upgrade the device to be upgraded. In the upgrading process, if the upgrading process is aborted, the equipment to be upgraded determines that the system file is missing after restarting, so that the equipment enters a downloading state and executes a breakpoint continuous transmission step.

And 102, if the system file is incomplete, entering a downloading mode, and reading the breakpoint record information by the equipment to be upgraded. The interruption point record information is determined according to the data packet identification information of the first upgrading data packet which is being downloaded before restarting the equipment to be upgraded and the corresponding partition identification information. The terminal device may write the packet identification information of the currently downloaded upgrade packet and the corresponding partition identification information into a storage medium of the device to be upgraded. After the current upgrading data packet is processed, when the next upgrading data packet is acquired, the data packet identification information and the partition identification information in the storage medium are updated, so that the effect of recording the upgrading progress is achieved.

Step 103, the device to be upgraded generates a break point record data packet according to the break point record information, wherein the break point record data packet comprises data packet identification information and partition identification information of the first upgrade data packet.

And 104, the device to be upgraded sends the break point record data packet to the upper computer device, so that the upper computer device continuously sends the upgrade data packet to the device to be upgraded from the first upgrade data packet according to the break point record data packet. Wherein, the break point record data packet may be implemented in the form of a packet data packet, and the format of the packet data packet including the break point record information is shown in table 1-1.

TABLE 1-1

Step 105, the upper computer device receives a break point record data packet sent by the device to be upgraded, where the break point record data packet includes data packet identification information and partition identification information of the first upgrade data packet.

Step 106, the upper computer equipment determines the position of the first upgrading data packet in the data packet sequence according to the data packet identification information and the partition identification information of the first upgrading data packet; the data packet sequence comprises a plurality of upgrading data packets, and the plurality of upgrading data packets are arranged according to a preset sequence. After receiving the data packet of the breakpoint record, the upper computer device analyzes the data packet of the breakpoint record, thereby obtaining the data packet identification information and the partition identification information of the first upgrading data packet.

And step 107, the upper computer equipment rejects the upgrade data packet before the first upgrade data packet in the data packet sequence according to the position of the first upgrade data packet in the data packet sequence so as to update the upgrade data packet contained in the data packet sequence. For example, the upper computer analyzes the upgrade file to obtain 100 data packets before starting the upgrade, and determines the data packet sequence. The upper computer equipment determines the 32 nd upgrade data packet in the data packet sequence of the first upgrade data packet according to the breakpoint record data packet, then the first 31 upgrade data packets in the data packet sequence can be removed, and the sequence of the rest upgrade data packets is kept unchanged, so that a data packet sequence containing 69 upgrade data packets is obtained.

And step 108, the upper computer equipment sends an upgrade data packet to the equipment to be upgraded according to the updated data packet sequence.

And step 109, the equipment to be upgraded performs system upgrade according to the upgrade data packet sent by the upper computer equipment. The system comprises an upgrade data packet, an upgrade file, a plurality of partitions, a plurality of data storage units and a plurality of data storage units, wherein the upgrade data packet is obtained after the upgrade file is analyzed, the upgrade file corresponds to the partitions, each partition corresponds to the upgrade data packet, and the upgrade file is used for upgrading a system of equipment to be upgraded. For example, the upper computer device disassembles an image file (upgrade file) into 100 upgrade data packages, and divides 10 partitions each containing 10 upgrade data packages. The equipment to be upgraded analyzes the upgrade data packet sent by the upper computer equipment and allocates a cache space. And the equipment to be upgraded writes the parsed upgrading data packet into a storage medium of the equipment to be upgraded, and updates the interrupt point record information according to the data packet identification information of the upgrading data packet and the corresponding partition identification information. And after the equipment to be upgraded acquires all the upgrading data packets corresponding to the target partition, the target partition can be updated. After all the partitions are updated, the target system file can be updated to ensure the system integrity. And then, the equipment to be upgraded clears the breakpoint record information and executes system restarting so as to complete system upgrading.

In some embodiments, there may be instances where the device to be upgraded will be involved in the command processing loop because it is not powered down and the download stream Cheng Yiwai is suspended. Therefore, when the equipment to be upgraded does not acquire the upgrade data packet sent by the upper computer equipment within the preset time, the information of the interruption point record is updated according to the acquired upgrade data packet, and the system is restarted. Optionally, the terminal device may execute the system restart when the terminal device does not acquire the control instruction sent by the upper computer device within the preset duration.

In some embodiments, the breakpoint resume method provided by the embodiment of the present invention may be implemented by improving an existing BSL protocol interaction instruction. Optionally, the following actions may be added to the response functions of bsl_cmd_start_data, bsl_cmd_ MIDST _data, and bsl_cmd_end_data instructions in the BSL protocol: the name of the current transmission partition is recorded in the BSL_CMD_START_DATA instruction action, and the sequence number CNT of the current transmission DATA packet is set to 0; the first execution will erase the second stage application loader (Secondary program loader, spl) partition (corresponding to the erase target system file in step above). And after the BSL_CMD_ MIDST _DATA instruction action processes the transmission DATA and processes one packet of DATA, carrying out +1 operation on the DATA packet sequence number CNT. If the data is processed in the background, the sequence number of the data packet processed in the background is recorded. In order to prevent the memory area from being accessed too frequently, the partition name and the partition serial number record are written into the memory once only when the CNT is an integer multiple of a preset threshold value. The recorded storage location selects an area that the terminal program will not access frequently. The bsl_cmd_end_data action confirms that the DATA transmission of the current partition has ended, and the record information is written once. Therefore, after the device is restarted, the firmware program of the device to be upgraded detects the spl program missing, so that the device enters a downloading mode and sends the interrupt point record information to the upper computer device.

In a specific example, the breakpoint continuous transmission method provided by the invention comprises the following implementation steps: after restarting the device to be upgraded, the firmware program detects whether the spl program is complete. If the spl program is incomplete, the download mode is entered. At this time, the upper computer device detects that the device to be upgraded is restarted, and transmits source codes of the first-level downloading program (File Download Loader, FDL 1) and the second-level downloading program (File Download Loader, FDL 2) to the device to be upgraded. The FDL1 is used for indicating the equipment to be upgraded to finish DDR initialization and FDL2 downloading. The FDL2 is used for indicating the device to be upgraded to complete downloading of all other image files (i.e. a plurality of upgrade data packets obtained by disassembling the upgrade files). After that, the device to be upgraded executes the FDL2 source code, the FDL2 transmits the interrupt point record data packet to the upper computer device, and after receiving the interrupt point record data packet, the upper computer regenerates a transmission sequence according to the packet sequence number and the partition name, and transmits the packet (upgrade data packet).

Corresponding to the breakpoint resume method, an embodiment of the present invention provides a schematic structural diagram of a device to be upgraded, as shown in fig. 2, where the device includes: a first processing module 201, a reading module 202 and a first communication module 203.
