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
The invention belongs to computer software application field, be specifically related to a kind of program Solidification method based on Ethernet.
Background technology
Embedded software, after exploitation debugging, need to be cured in the Flash storer of target machine by solidification software.Solidification process, is mainly divided into and will treats that by treating that curing document is loaded into be loaded end (target machine) and to be loaded end from loading end (being generally PC) curing document writes two steps of Flash storer.To treat that curing document is loaded into and is loaded end from loading end, can adopt different transmission mediums, as serial ports, Ethernet, AFDX bus etc.Under different transmission medium conditions, spent time of file loading procedure is also different.Such as adopting serial ports as transmission medium, file transfer speed is low, in the time solidifying large file, need to expend for a long time, and curing efficiency is low.Therefore, adopt a kind of transmission medium of two-forty, can shorten the load time, improve curing efficiency.

3.2.2] continue to receive and load packet, judge and in current received loading packet, treat curing document ID and treat that whether curing document ID is consistent in a upper loading packet:
As treated in received loading packet, curing document ID loads and treats that curing document ID is consistent in packet with upper one, belong to a loading packet for the treatment of curing document, the valid data that comprise in received current loading packet are stored in the corresponding memory headroom of current block number;
As treated in received loading packet, curing document ID and upper one load and treat that curing document ID is inconsistent in packet, belong to the next one and treat the loading packet of curing document, be the current curing document application correspondence memory space for the treatment of according to file total block data in the current loading packet receiving, obtain the current start address for the treatment of curing document memory headroom;
Valid data in current loading packet are stored in the corresponding memory headroom of current block number institute;
The file loader that is loaded end is written to ID, the memory headroom start address for the treatment of curing document in file load information table;
Treat that the valid data total length of curing document is written to the relevant position of file load information table for upper one that accumulative total is obtained simultaneously;
3.2.3] get back to step 3.2.2], until do not receive loading packet;
3.3] return to loading command respond packet to loading end;
3.4] loading end sends programming packet:
3.4.1] loading end sends multiple programming packets to being loaded end, comprises and treat that curing document ID and corresponding Flash storer solidify address in described programming packet;
3.4.2] be loaded termination and receive after all programming packets, according to treating in each programming packet that curing document ID solidifies address by its corresponding Flash storer and adds in file load information table;
4] being loaded end calls and writes Flash driver and will treat that curing document solidifies one by one in Flash storer according to file load information table.
In step 4] also comprise afterwards checking procedure:
The curing document content for the treatment of having cured in content and the memory headroom of the curing document in Flash storer is compared one by one, and comparison result is returned to loading end.
Above-mentioned steps 1] concrete steps be
1.1] being loaded end starts the operating system;
1.2] file loader initialization, by the zero clearing of file load information table;
1.3] open a target machine socket based on connecting;
