Embodiment Construction

[0039] The general platform for system debugging and monitoring of the present invention adopts the system framework of hardware-assisted software, as shown in Figure 1: the general platform 2 is connected to the target hardware system through the JTAG line or the JTAG transfer interface, and the target hardware system can be a target with a JTAG interface Single board 1, so as to obtain the JTAG signal, and further realize functions such as debugging, performance testing and memory analysis through the platform software.

[0040] The general platform is mainly divided into three parts, which are JTAG interface part A, data processing part B and human-computer interaction interface C.

[0041] The flow of information is shown in Figures 2 and 3, including: 210) the user inputs operation information and requirements through the man-machine interface C, such as debugging or tracking information and setting breakpoint requirements; 220) the man-machine interface C converts the ope...

Abstract

The invention relates to a universal platform for a system debugging monitor and a related method, in which, the universal platform (2) includes a JTAG processing host computer adopting JTAG interfaces; the method comprises the following steps: establishing mutual communications junction between the platform and target system chips through respective JTAG interfaces according to communications interface standards of JTAG; transmitting standard JTAG format protocol flows transformed by custom instruction with communications junction and having response of the target system (1) chips; reading standard JTAG format protocol flows transformed by chip debugging information and register state information of the target system with communications junction, and reducing the standard JTAG format protocol flows to computer-readable data for displaying and outputting after treatment. The universal platform and the method thereof, with JTAG standards, can provide a universal tool for different chips with JTAG interfaces to monitor and debug abnormal phenomenon, such as dead loop and memory leakage of the system or a single board under non-debugging conditions, thus satisfying the debugging and monitoring demands of the system or the single board under various environments including on-site situation.

Description

technical field [0001] The invention relates to hardware system debugging and monitoring, in particular to a general platform and method for debugging and monitoring various hardware systems with JTAG interface chips, especially single boards, in various environments including on-site by using JTAG technology. Background technique [0002] At present, different types of single boards use different debugging tools and different debugging interfaces (such as serial ports, network ports, etc.) However, the problems in the officially released system cannot be located and eliminated. The main reasons for the above problems are: the traditional debugging tools and methods are overly dependent on the chip pins, cannot work normally under the high-speed operation of the processor, occupy system resources and cannot track and hardware breakpoints in real time, and are too expensive. Currently, the use of embedded high-end processors is becoming more and more popular. These processo...
