Embodiment
[0029] Taking the remote upgrade backup of the chip STM32 as an example, the system hardware used to realize the remote upgrade is as follows: figure 1 shown.
[0030] It includes a stm32 controller, a remote server, and an industrial computer. The stm32 controller is connected to the industrial computer, and the remote server performs data interaction with the industrial computer. Among them, the industrial computer has communication methods including but not limited to wifi, 2 / 3 / 4G, UART serial port, network port, and CAN. The industrial computer is responsible for interactive processing of uplink data with the server, and interactive processing of downlink data with the stm32 controller.
[0031] The upgrade process is as follows figure 2 As shown, it includes the following implementation steps:
[0032] Step 1. Compile the chip program source code of the controller to generate a bin file:
[0033] In this step, the source code of the stm32 chip program can be compiled ...

The invention relates to an embedded equipment software upgrading technology, discloses a remote upgrading backup method of embedded chip software, and solves the problems of inconvenience in field upgrading and equipment failure caused by failure of traditional remote upgrading. The method can be summarized as follows: a chip program source code of a controller is subjected to compiling to generate a bin file, and the bin file is uploaded to a far-end server for storage; the server encrypts the upgrade data packet and then issues the encrypted upgrade data packet to the industrial personal computer for corresponding decryption and judging the correctness of the data; the industrial personal computer packs and unpacks the upgrade data packet according to a protocol and transmits the upgrade data packet to the controller; after upgrading data transmission is completed and verification is passed, the controller is reset and restarted, and then the BootLoader area is executed; the upgrading data of the APPBAK area is copied to the APP area by the BootLoader, file verification is carried out, and a verification result is written into a param parameter area; and the BootLoader reads theverification result of the param parameter area to judge the upgrading result so as to determine whether the program jumps to the APP area or the factory backup area.
Description
technical field [0001] The invention relates to an embedded device software upgrade technology, in particular to a remote upgrade backup method for embedded chip software. Background technique [0002] At present, when various types of embedded devices are upgrading their functional versions, the programs of the embedded devices need to be reprogrammed. The traditional upgrade method is to program on-site programming through the corresponding emulator. This method requires on-site operation by the manufacturer's personnel, and it is extremely inconvenient to program the controller on-site for embedded devices that are difficult to disassemble. [0003] In addition, there are currently remote upgrade solutions for some embedded devices, but the success rate is not high, and it is easy to cause the control board to fail to work normally, resulting in device failure. Contents of the invention [0004] The technical problem to be solved by the present invention is to propose ...
