Embodiment Construction

[0065] General embedded computer software online upgrading method of the present invention, the system structure that it realizes is referring to appendix figure 1 . It includes an online upgrade server (101), a communication medium (102), and an embedded computer (103). The online upgrade server (101) is connected to the embedded computer (103) through the communication medium (102).

[0066] Upgrade server online:

[0067] The online upgrade server provides online upgrade services, and usually exists in the form of an executable program in a computer.

[0068] For the upgrade steps of the online upgrade server, see the attached figure 2 .

[0069] Step [201], start upgrading.

[0070] Step [202], read the upgrade file header. The file header is the first 8 bytes of the upgrade file, and the first half of the 4 bytes is the checksum of all subsequent data (the last 4 bytes of the file header and all data in the upgrade file except the file header), The last 4 bytes are...

Description

technical field [0001] The invention belongs to the technical field of embedded devices, and in particular relates to a general online upgrading method for embedded computer software. Background technique [0002] Traditional embedded computers, due to the limitations of hardware resources (for example, small capacity of program memory, slow operation speed, no external communication interface or slow speed of external communication interface), the user program is solidified into the program memory during the production stage. The user program cannot be changed at will. If there is a problem with the program during operation, or the function needs to be improved, it can only be returned to the factory for repair, or the hardware board can be replaced by disassembling the machine on site. [0003] With the continuous development of science and technology, hardware resources in embedded computers are becoming more and more abundant, which provides hardware guarantee for embed...
