A jtag remote debugging method

Abstract

The invention discloses a JTAG remote debugging method and relates to the field of JTAG debugging. A JTAG Ethernet remote debugging method, comprising: JTAG conversion module power-on self-inspection or no self-inspection; checking or not checking whether the JTAG conversion module is connected to the debugging center; the debugging center carries out framing and packaging of debugging data or receives JTAG conversion The data packet uploaded by the module is parsed; the JTAG conversion module receives the data packet sent by the debugging center or sends the data packet returned by the JTAG of the device under test to the debugging center; the JTAG conversion module receives the data packet from the debugging center or sends the data to the debugging center The package distinguishes different devices under test and different debugging centers through different IP addresses and port addresses; parses the JTAG protocol, including serial-to-parallel conversion and parallel-to-serial conversion, FIFO buffer, timing synchronization and other digital signal processing processes. The present invention can use one or more computers to debug multiple corresponding devices; the main function realized by integrating the JTAG conversion module is to convert Ethernet to JTAG.

Description

technical field [0001] The invention relates to the field of JTAG debugging, in particular to a JTAG remote debugging method. Background technique [0002] With the continuous development and application of embedded systems, more and more attention has been paid to the development of embedded software for different applications. In the field of system design, the development of application software is becoming more and more expensive and time-consuming. A good debugger can give embedded software developers a good help and achieve twice the result with half the effort. With the increasing complexity of chip designs, the software development and system debug phases are an important part of the time to market. At the board level, system function debugging through software simulation, verification and analysis is far from meeting the requirements of functional correctness debugging and fault location, so it is very important to support on-chip testing and debugging functions o...

AI Technical Summary

Problems solved by technology

The traditional method is USB to JTAG, which cannot realize remote debugging, and it is very inconvenient to use under certain conditions

And in the traditional way, the same computer can only debug one corresponding device, and multiple computers cannot coordinate debugging of multiple devices
