DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.

[0024] The embodiment of the present application provides a method for upgrading software of a processing core, which is applied to a processing system, wherein the processing system includes a plurality of processing cores, and the processing system is connected to a serial terminal device via a serial port; the serial terminal device pre-stores an upgrade file; Figure 1 As shown, Figure 1 A flowchart of a method for upgrading the software of a processing kernel provided in an embodiment of the present application. The method comprises the following steps: S101, the processing system sends an information collection instruction to a serial port terminal device.

[0025] Specifically, the above-mentioned processing system is equipped with PSOC (Programmable System-on-Chip) of Fudan Microelectronics. The model of PSOC is JFMQL15T485. PSOC integrates PS (Processing System) and PL (Programmable Logic) of a quad-core processor with rich features on a single chip. Among them, PS is the core of PSOC. PS works together with on-chip memory, DDR (Double Data Rate) interface, various system functional components, peripheral I / O (Input / Output) interface and PL to form a feature-rich programmable system on chip. Figure 2 As shown, Figure 2 A connection relationship diagram of a processing system and a serial terminal device provided in an embodiment of the present application. The processing system 200 is connected to the serial terminal device 300 via an RS-232 serial port. The above-mentioned processing cores include processing core 0, processing core 1, processing core 2, and processing core 3. Bootloader software is provided in processing core 0. Processing core 0 upgrades the software of the above-mentioned processing cores through the bootloader software. The bootloader software generates the above-mentioned information collection instruction.

[0026] The information collection instruction includes: requesting the serial port terminal device 300 to send the serial number of the processing core to be upgraded, requesting the serial port terminal device 300 to send the serial number of the processing core to be run, requesting the serial port terminal device 300 to send the preset burning position corresponding to the serial number of the processing core to be upgraded, requesting the serial port terminal device 300 to send the preset loading position corresponding to the serial number of the processing core to be run, and requesting the serial port terminal device 300 to send the memory length occupied by the upgrade file. The information collection instruction is used to request the serial port terminal device to send control information.

[0027] S102, the processing system receives control information fed back by the serial port terminal device according to the information collection instruction.

[0028] The control information includes the serial number of the processing core to be upgraded.

[0029] Specifically, the serial port terminal device 300 stores and runs a script file in advance, and the script file stores control information. After receiving the information collection instruction, the serial port terminal device 300 selects control information from the script file according to the request of the information collection instruction.

[0030] With such a configuration, the processing system 200 can automatically obtain the control information sent by the serial port terminal device 300, so that when the software of the processing core is subsequently upgraded, the upgrade file can be automatically burned to obtain the burning data, thereby saving manpower, saving the time for upgrading the software of the processing core, and improving the upgrade efficiency of the software of the processing core.

[0031] S103, the processing system obtains the upgrade file sent by the serial port terminal device.

[0032] Specifically, the staff loads the upgrade file to the serial terminal device 300. After receiving the information collection instruction sent by the processing system 200, the serial terminal sends the upgrade file to the processing system 200 through a pre-agreed communication protocol, such as the Ymodem protocol.

[0033] S104, the processing system burns the upgrade file according to the serial number of the processing core to be upgraded, generates burning data corresponding to the upgrade file, and upgrades the software of the processing core to be upgraded according to the burning data.

[0034] Specifically, the processing system 200 burns the upgrade file and generates burning data corresponding to the upgrade file, thereby ensuring the permanent preservation of the upgrade file.

[0035] The embodiment of the present application provides a method for upgrading the software of a processing kernel, in which the processing system 200 receives the control information fed back by the serial terminal device 300 according to the information collection instruction, burns the upgrade file according to the sequence number of the processing kernel to be upgraded, generates the burning data corresponding to the upgrade file, and upgrades the software of the processing kernel to be upgraded according to the burning data. Compared with the prior art, in which the update configuration parameters corresponding to the processing kernel are burned into the processing system 200 manually according to the upgrade requirements to achieve the upgrade of the processing kernel, this method does not require manual matching of each update configuration parameter with the processing kernel, and manually burning it into the processing system 200, thereby achieving the automatic upgrade of the software of the processing kernel. This method saves manpower, saves the upgrade time of the software of the processing kernel, and improves the upgrade efficiency of the software of the processing kernel. In addition, since the step of matching each update configuration parameter with the software of the processing kernel by manpower is omitted, the matching result of the update configuration parameter with the processing kernel is more accurate, thereby improving the upgrade success rate of the processing kernel, and greatly reducing the situation of upgrade failure caused by human error.

[0036] The following is an introduction to the way in which the processing system 200 burns the upgrade file according to the serial number of the processing core to be upgraded. The above control information also includes: the above control information also includes: the preset burning position corresponding to the serial number of the processing core to be upgraded; the processing system determines the target burning position of the upgrade file according to the preset burning position corresponding to the serial number of the processing core to be upgraded, burns the upgrade file into the target burning position of the upgrade file, and generates burning data corresponding to the upgrade file.

[0037] Specifically, the processing system 200 has a FLASH (Flash EEPROM Memory) module 400. The processing system 200 burns the upgrade file into the FLASH module 400. The FLASH module 400 is a non-volatile memory that can keep the stored data from being lost in the event of a power outage, and can ensure that the processing system 200 can automatically load the upgrade file after restarting or powering off without re-downloading or reconfiguring. The FLASH module 400 can be expanded to 32MB for use. The above-mentioned processing system 200 accesses the FLASH module 400 through QSPI (Quad Serial Peripheral Interface), and the processing system 200 can perform operations such as reading, writing, erasing, and programming on the QSPI.

[0038] like Figure 3 As shown, Figure 3A schematic diagram of the FLASH module structure provided in an embodiment of the present application. The FLASH module 400 uses 8M-10M space to store app0, 10M-12M space to store app1, 12M-14M to store app2, and 14M-16M to store app3. Among them, app0 is the burning data generated by processing kernel 0 to burn the upgrade file, app1 is the burning data generated by processing kernel 1 to burn the upgrade file, app2 is the burning data generated by processing kernel 2 to burn the upgrade file, and app3 is the burning data generated by processing kernel 3 to burn the upgrade file. In the above-mentioned FALSH module 400, app0, app1, app2, and app3 occupy 3MB of usage space respectively, and the offset base address is 0x1000000. The FALSH module 400 burns the upgrade file into the target burning position (app0, app1, app2, app3) of the upgrade file through the bootloader software. A 128KB storage space is pre-set in the FLASH module for storing the above-mentioned control information.

[0039] This method ensures the persistent preservation of the upgrade file, and can ensure that the processing system 200 can automatically load the upgrade file after restart or power failure without re-downloading or reconfiguring, thereby improving the reconfigurability of the upgrade file storage.

[0040] In one embodiment, the control information further includes: the serial number of the processing core to be run, the preset loading position corresponding to the serial number of the processing core to be run, and the memory length occupied by the upgrade file. The processing system determines the target base address of the burning data corresponding to the upgrade file according to the preset loading position corresponding to the processing core to be run, determines the target memory space of the burning data corresponding to the upgrade file according to the target base address of the burning data corresponding to the upgrade file, reads the burning data corresponding to the upgrade file according to the memory length occupied by the upgrade file, moves the burning data corresponding to the upgrade file to the target memory space of the burning data corresponding to the upgrade file, and runs the burning data corresponding to the upgrade file in the target memory space of the burning data corresponding to the upgrade file.

[0041] Specifically, the processing system 200 has a DDR (Double Data Rate) module 500. The bootloader software in the processing system 200 can transfer the programming data corresponding to the upgrade file from the above-mentioned FALSH module 400 to the DDR module 500. Figure 4 As shown, Figure 4Schematic diagram of the DDR module structure provided by the embodiment of the present application. core0 indicates that the target base address of the upgrade file run by processing core 0 is 0x800000, core1 indicates that the target base address of the upgrade file run by processing core 1 is 0x1000000, core2 indicates that the target base address of the upgrade file run by processing core 2 is 0x1800000, and core3 indicates that the target base address of the upgrade file run by processing core 3 is 0x2000000. Each of the above target memory spaces is 8MB. After the software upgrade of the processing core to be upgraded is completed, the processing system 200 will be powered off and restarted so that the processing system 200 runs the corresponding burning data of the upgrade file according to the sequence number of the processing core to be run to verify whether the software of the upgraded processing core to be upgraded is successfully upgraded.

[0042] In this method, the burning data corresponding to the upgrade file is run according to the sequence number of the processing core to be run. Among them, the processing core to be run can be one of the processing core 0, processing core 1, processing core 2 and processing core 3, or two, or three, or all of them, which has high flexibility.

[0043] In one implementation, the processing system sends a request to start an upgrade instruction to the serial terminal device; If the processing system receives the upgrade start instruction fed back by the serial port terminal device according to the upgrade start instruction request within the preset time, the processing system generates an information collection instruction.

[0044] Specifically, before upgrading the software of the processing core, the processing system 200 will send a request to start the upgrade instruction to the serial port terminal device 300. The script file at the serial port terminal device 300 will automatically feed back the start upgrade instruction to the processing system 200 according to the request to start the upgrade instruction. The start upgrade instruction is U enter. The processing system 200 will wait for receiving the start upgrade instruction (U enter) within a preset time. If the processing system 200 receives the start upgrade instruction (U enter) within the preset time, it means that the FLASH module 400 in the processing system 200 needs to burn new control information. At this time, the processing system 200 needs to send an information collection instruction to the serial port terminal device 300 to obtain the control information required for the software upgrade of the processing core from the serial port terminal device 300. The preset time is 50ms.

[0045] In this manner, the serial port terminal device 300 can determine whether to feed back the start-upgrade instruction to the processing system 200 according to the request start-upgrade instruction, thereby accurately controlling the upgrade process of the software of the processing kernel in the processing system 200 .

[0046] In one implementation, if the processing system does not receive the upgrade startup instruction fed back by the serial port terminal device according to the upgrade startup instruction request within a preset time, the processing system runs the burning data corresponding to the pre-stored upgrade file.

[0047] Specifically, the processing system 200 waits for 50ms (within the preset time) but does not receive the request to start the upgrade instruction (U enter) fed back by the serial port terminal device 300, then it will run the burning data corresponding to the previous (pre-stored) upgrade file based on the control information stored in the preset 128KB storage space in the FLASH module 400.

[0048] In this manner, even if the processing system 200 does not receive the request to start the upgrade instruction fed back by the serial port terminal device 300, the burning data corresponding to the last (pre-stored) upgrade file can be executed, which has high flexibility.

[0049] In one implementation, the processing system burns the upgrade file according to the sequence number of the next processing core to be upgraded, and generates the next burning data corresponding to the upgrade file.

[0050] Specifically, after the software upgrade of the previous processing core is completed, the processing system can automatically burn the upgrade file according to the sequence number of the next processing core to be upgraded to complete the software upgrade of the next processing core to be upgraded.

[0051] In this way, the processing system can continuously burn the upgrade file without human intervention, thus realizing the automatic upgrade of the software of the processing core. This method saves manpower, saves the upgrade time of the software of multiple processing cores, and improves the upgrade efficiency of the software of multiple processing cores.

[0052] Based on the above method embodiment, the embodiment of the present application also provides a software upgrade system for a processing core, wherein the processing system 200 includes multiple processing cores, and the processing system 200 is connected to a serial port terminal device 300 via a serial port; the serial port terminal device 300 stores an upgrade file in advance.

[0056] Preferably, the sending module 51 is further used to send a request to start the upgrade instruction to the serial terminal device; The control module 53 is further configured to generate an information collection instruction if the processing system receives an upgrade start instruction fed back by the serial port terminal device according to the upgrade start instruction request within a preset time.

[0057] Preferably, the control module 53 is further configured to execute the burning data corresponding to the pre-stored upgrade file if the processing system does not receive the upgrade startup instruction fed back by the serial port terminal device according to the upgrade startup instruction request within a preset time.
