as shown in fig. 3, after the embedded system is started, the CPU starts to run the BootLoader program from address 0x00000000, sends the interactive information to secureCRT through the USB, performs 5s countdown, and waits for the control information input from the secureCRT terminal;
if the countdown of 5s is finished, the BootLoader program does not receive the preset input information, and the preset input information is the key-in h of the user in the embodiment, the program is switched to the process of executing the application program;
if the BootLoader program within 5s receives the information that the user types h, the program enters a configuration mode, sends the configuration mode interaction information to a secureCRT remote control terminal, and waits for the remote control terminal to input control information;
in the configuration mode, when the BootLoader program receives the information of e typed by the user, the BootLoader program is shifted to the process of executing the application program;
in the configuration mode, when the BootLoader program receives the information that the user enters 1, the BootLoader program is switched to execute a program downloading process;
in this embodiment, the program downloading process is completed by the downloading unit 1071 of the program downloading control module interacting with the secureCRT remote control terminal. Specifically, a file transmission mode is selected through secureCRT, and in this embodiment, Ymodem is selected; selecting a target application program file for updating, in the embodiment, selecting a bin application program file; executing file transmission;
in the process of downloading the program, the downloaded program is firstly cached in the DDR module 105, after the transmission is completed, the application program backup area of the Flash module 104 is erased, and then the application program file in the DDR is written into the backup area, so that the damage of the application program caused by the power failure in the process of downloading the program is prevented.
After the application program is written, setting an update mark in a BootLoader parameter area as a new program to be updated, and then switching to the process of executing the application program;
in this embodiment, the program downloading process is completed by the execution unit 1072 of the program downloading control module 107, and the specific process is as follows: firstly, acquiring a BootLoader parameter area mark to check whether a new program is to be updated, if no new program is to be updated, considering the program of the current Flash application program area as the latest program to be executed, directly jumping to an address 0x00100000 of the application program area by a CPU, and running the application program;
if the Flash BootLoader parameter area mark indicates that a new program is to be updated, executing program update: erasing the application program area, copying the program of the application program backup area to the application program area, and clearing the Flash BootLoader parameter area after copying is finished to have a new program to-be-updated mark, namely setting the mark as no new program to be updated; and after the program is updated, setting the CPU to jump to the address 0x00100000 and starting to execute the function of the new application program.
By adopting the interactive remote control updating operation, the updating process of the embedded system is simplified, the dependence of the updating operation on specific hardware and interfaces is reduced, and the updating process is convenient to control. Meanwhile, Flash is reasonably partitioned, and a program backup area and an update mark are set, so that safe update is realized.
