Problems solved by technology

For example, if serial port is used as the transmission medium, the file transfer rate is low. When curing large files, it takes a long time and the curing efficiency is low.

Embodiment Construction

[0047] The specific implementation steps of the program solidification method based on Ethernet are as follows:

[0048] Step 1: The loaded end starts the operating system, initializes the file loader, starts the file loading task, establishes a communication port, and waits to receive a command request from the loading end.

[0049] The implementation process of this step is as follows:

[0050] 1.1) The loaded end starts the operating system;

[0051] 1.2) The file loader is initialized, and the file loading information table is cleared;

[0052] 1.3) Open a connection-based target machine socket;

[0053] 1.4) Bind the target machine socket with its address;

[0054] 1.5) Enable target machine socket connection;

[0055] 1.6) Waiting to receive the loader command request;

[0056] Step 2: The loading end establishes a network connection with the loaded end to complete the synchronization.

[0057] The implementation process of this step is as follows:

[0058] 2.1) T...

Abstract

The invention relates to a program solidifying method based on the Ethernet. The method comprises the steps of initializing an end to be loaded, establishing network connection between a loading end and the end to be loaded so as to finish synchronization, enabling the loading end to load files to be solidified to the end to be loaded, and enabling the end to be loaded to solidify the files to be solidified into a Flash storer one by one through calling a writing Flash drive program according to a file loading information table. According to the program solidifying method, the characteristic that the Ethernet is quicker in transmission speed than media such as serial ports is utilized, and the files to be solidified are loaded from the loading end to the end to be loaded quickly, so that time needed by loading files is effectively shortened, and program solidifying efficiency is improved.

Description

technical field [0001] The invention belongs to the field of computer software applications, and in particular relates to an Ethernet-based program curing method. Background technique [0002] After the embedded software is developed and debugged, it needs to be solidified into the Flash memory of the target machine through the firmware. The curing process is mainly divided into two steps: loading the file to be cured from the loading end (generally a PC) to the loaded end (target machine) and writing the file to be cured into the Flash memory by the loaded end. To load the file to be cured from the loading end to the loaded end, different transmission media can be used, such as serial port, Ethernet, AFDX bus, etc. Under different transmission medium conditions, the time spent in the file loading process is also different. For example, if a serial port is used as the transmission medium, the file transfer rate is low. When curing large files, it takes a long time and the ...
