Problems solved by technology

At present, most of the programming methods are based on the JTAG interface (Joint Test Action Group, a joint test action group, which is an international standard test protocol, mainly used for chip internal testing and system simulation and debugging). This method has The advantages of easy operation and convenient debugging, but will be limited by space and transmission distance
For example: a DSP (digital signal processing) system installed in a complex and closed environment, when the program needs to be updated or upgraded, it is difficult to use the JTAG interface to realize online programming of FLASH
[0003] Although the programming technology based on the JTAG interface is used in the R&D and debugging stage, it is difficult to implement in the finalization stage, especially for the field loading and remote control of airborne and missile-borne equipment.

Abstract

The invention discloses an embedded remote device program programmer device and method and belongs to the technical field of embedded remote device program converting. The embedded remote device program programmer device comprises an intelligent terminal, an internet access, a serial port/ universal serial bus (USB) port, a joint test action group (JTAG) port, a simulator, an electronic switch and a target machine and further comprises an ethernet port to serial port converter for converting information of an ethernet port to a serial port. Compared with the existing method for programming based on the JTAG port, the serial port programmer method is free of limitation from space and transmission space, and is easy to operate, convenient to debug and capable of effectively reducing maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of embedded remote equipment program conversion, in particular to an embedded remote equipment program programming device and method. Background technique [0002] After the hardware system and software program design of a control system are completed, the software program needs to be written into the FLASH memory to solve the problem that the controller will erase the program due to power failure, and realize the purpose of system offline operation. At present, most of the programming methods are based on the JTAG interface (Joint Test Action Group, a joint test action group, which is an international standard test protocol, mainly used for chip internal testing and system simulation and debugging). This method has It has the advantages of easy operation and convenient debugging, but it will be limited by space and transmission distance. For example: a DSP (digital signal processing) system installed in a ...
