Description

Embedded device debugging system and method thereof

technical field

The invention relates to the application field of an embedded device, in particular to a debugging system and a method for the embedded device.

Background technique

Embedded System (Embedded System) is a computer system embedded in mechanical equipment or electrical devices and has specific functions. Unlike personal computers, which can handle different computing needs by installing various programs, embedded systems can only process And control a single specific function, thereby improving the reliability and operating efficiency of the specific function.

Today, embedded systems or devices have been widely used in telecommunication systems, consumer electronics products, smart home appliances and systems, transportation and transportation systems, and medical equipment and systems. A general personal computer can perform a self-test program to test whether each hardware component in the personal computer can operate normally when it is turned on. If there is a hardware failure, specific codes can be output according to different test points and displayed on the display device, and maintenance personnel can learn the cause of the failure from the displayed codes for subsequent maintenance work. However, embedded devices are different from ordinary personal computers. They usually do not have components such as keyboards, screens, or hard disks. Therefore, maintenance personnel need to upload the debugging data in the embedded devices to the computer through a special debugging device for further processing. Troubleshooting work. In the early days, a kind of debugging device was proposed in Taiwan Patent Publication No. TWI348615, which can read the debugging information stored in the memory of the embedded device through an interface interface compatible with the embedded device; Publication No. TWI546660 proposes a debugging system, in which a computer reads debugging information in a memory unit of an embedded device through an in-circuit emulator. Due to the wide variety of transmission interface interfaces of embedded devices, specific debug devices or in-circuit emulators can only be applied to specific embedded devices, so maintenance personnel need to carry a variety of different debug devices when repairing embedded devices Device or in-circuit emulator to read the debug data in the embedded device, which may cause inconvenience in maintenance. In addition, users of general embedded devices do not know how to use debug devices or internal circuit emulators, so they cannot perform testing by themselves.
