In the existing technology, after the software crashes, it must be restarted. Before the restart, the debugging information may not be output, and the system operation status and data cannot be obtained; after the restart, the program and data must be reloaded, and this process will destroy the system. Therefore, it is impossible to effectively analyze and diagnose system faults

Embodiment Construction
[0021] Below in conjunction with embodiment the present invention is further described.
[0022] Such as figure 2 Shown, a kind of fault diagnosis method of embedded system is characterized in that comprising the following steps:
[0023] A. A fault diagnosis system is set in the embedded system, and the storage area of the fault diagnosis system is separated from the storage area of the main system;
[0024] B. When an error occurs during the operation of the main system and the system crashes, and the main system no longer responds or cannot respond to user operations correctly, start the diagnostic system, and the diagnostic system reads the main system fault site data and analyzes the fault data.
[0025] Such as figure 2 , image 3 As shown, set a fault diagnosis button, press the fault diagnosis button to start the fault diagnosis system, after the fault diagnosis system runs, initialize the communication port, read the symbol table of the main system, read the ...

The invention relates to an embedded system fault diagnosis method and an embedded system with fault diagnosis and relates to an embedded system and a fault diagnosis method thereof. The embedded system fault diagnosis method includes A, a fault diagnosis system is set in the embedded system, and a storage area of the fault diagnosis system is separated from a storage area of a main system; and B, during the operation process of the main system, when the main system can't correctly respond to user operations, the diagnosis system is started to read fault field data of the main system and analyze the fault data. The embedded system with the fault diagnosis comprises at least one processor, a main system module, a memory, a boot loading module, a communication port, a reset button, a fault diagnosis module and a fault diagnosis button, the memory is divided into two parts, one part of the memory is used for operating the main system, the other part of the memory is used for operating the fault diagnosis system, and the two parts aren't mutually overlapped. According to the embedded system fault diagnosis method and the embedded system with the fault diagnosis, during the operation process of the embedded system, users can read and analyze the fault field data if the main system has crash faults, so that maintainability and diagnosability of the system are improved.
Description
technical field [0001] The invention relates to an embedded system and a fault diagnosis method thereof. Background technique [0002] In currently known technologies, an embedded system is composed of a CPU system and software running on it, and the software may have bugs and may crash during operation. In the existing technology, after the software crashes, it must be restarted. Before the restart, the debugging information may not be output, and the system operation status and data cannot be obtained; after the restart, the program and data must be reloaded, and this process will destroy the system. Therefore, it is impossible to effectively analyze and diagnose system failures. Contents of the invention [0003] One of the objects of the present invention is to provide a fault diagnosis method of an embedded system for diagnosing and analyzing the cause of the fault after the software of the embedded system crashes. [0004] The second object of the present invention...
