Problems solved by technology

The disadvantage of this external ICE device method is: the complicated and inconvenient wiring steps, and when the debugging/testing work is carried out on the finished product after commercialization, the case must be disassembled to expose the CPU on the circuit board before it can be carried out Wiring and testing, the inconvenience can be imagined
However, the cost of this method is high, and when it is applied to the finished product of electronic products, it is still necessary...

Abstract

The invention relates to a method to use existing connection port of electronic products to debug and its device, building integrated computer emulation (ICE) in the electronic products and connecting ICE with processor and O/I port, and converting the processor from normal operating mode to debugging mode to use ICE to emulate the processor, which can use the computer to execute debugging program, for executing error detecting/testing program, or remote debugging, downloading and F/W updating programs, etc. by the existing O/I port.

Description

(1) Technical field [0001] The present invention relates to a method and device for debugging by using the existing connection port of an electronic product, especially a method and device that can use the existing connection port of an electronic product to connect a computer to execute a specific program, and switch the internal processor to debug / test mode to facilitate debugging / testing methods. (2) Background technology [0002] Due to the rapid development of software and hardware technology, many computer peripheral products and daily-used electronic products have built-in processors to provide various execution functions. The use of processors involves the circuit design of hardware and the programming of programs written inside the processor. As for the software part, in fact, there are many ready-made processors on the market at present, and users can write programs according to their own needs, which can make the processor produce different execution functions. Si...
