Expandable modular multi-channel off-line programmer

Abstract

The invention provides an expandable modular multi-channel off-line programmer. The expandable modular multi-channel off-line programmer comprises an off-line programmer main board and N off-line programmer daughter boards, wherein N is an integer larger than 1.The off-line programmer daughter boards are fixed to the off-line programmer main board in a pluggable mode. The N off-line programmer daughter boards are identical independent modules, are each provided with an independent first USB interface and an independent first SWD interface and can independently complete off-line programming of Flash3 memories of target chips and updating of source programs. The off-line programmer main board comprises a second USB interface and N second SWD interfaces, the second USB interface is connected with the first USB interfaces of the off-line programmer daughter boards, the second SWD interfaces are connected with the second SWD interfaces of the off-line programmer daughter boards, and through the off-line programmer main board, the multi-channel off-line programmer can complete transmitting and updating of source programs and off-line programming of target chips. The expandable modular multi-channel off-line programmer can break through the limitation of the number of off-line programming channels, and thus the requirement for volume production can be met in the large-scale chip programming process; due to the fact that all channels are relatively independent, module maintenance and replacement can be conveniently carried out if one channel fails.

Description

technical field [0001] The invention relates to the field of embedded electronic products, in particular to an expandable modular multi-channel off-line programmer. Background technique [0002] In the production process of electronic products, it is necessary to use a programmer to download the software execution code to the hardware chip Flash memory. The programmer is a tool mainly used for chip programming of single-chip microcomputers. [0003] In the traditional burning process, a complete set of devices such as a PC, a burner, and a software development environment are needed to complete the burning of the program, and the operation process is complicated. [0004] With the development of technology, offline programmers have been produced one after another. The program files are stored in the programmer in advance, and then downloaded to the Flash memory of the target chip. The entire burning process no longer requires a PC and a software development environment, that...

Problems solved by technology

This offline programming method simplifies the hardware platform and programming process of program programming. Most of the offline programmers used are single-channel, and only one target chip can be programmed at a time. Although the production efficiency is greatly improved, However, due to the limitation of the number of off-line programming channels, in the process of large-scale programming of chips, this single-channel off-campus programmer still cannot meet the needs of mass production

[0005] Although there are currently some multi-channel programmers, if a channel of this kind of programmer fails, the whole machine will not work, it is inconvenient to maintain and replace modules, and it is expensive
