Embedded software debugging system and method

Abstract

The invention discloses an embedded software debugging system and method. A DSP (Digital Signal Processor) acquisition module comprises a DSP main processing module and an acquisition module; the DSPmain processing module is used for having a DSP active debugging information output function, uniformly using acquired data as target data after packaging the acquired data by an additional protocol and sending the target data to a MCU (Microprogrammed Control Unit) parsing unit by a special interface; the MCU module is used for carrying out processing and parsing on a received signal, if debugging is not real-time debugging, transmitting the processed data to a storage module for storage, and then when waiting equipment to be connected with an upper computer or other equipment capable of carrying out display output, outputting and displaying target debugged contents by a UART (Universal Asynchronous Receiver / Transmitter) circuit for debugging personnel to analyze and use. According to thesystem, by the above design, acquisition and storage of the debugged data in a case that no debugging interface is provided or real-time capturing cannot be carried out can be implemented, and the embedded software debugging system and method are more applicable to data acquisition in the post maintenance phase of a product; the integral circuit structure is greatly simplified, manufacturing costis low, and the embedded software debugging system and method are convenient for integration.

Description

technical field [0001] The invention relates to the technical field of embedded software, in particular to an embedded software debugging system and a method thereof. Background technique [0002] Today's embedded devices have occupied all aspects of our lives, such as automobiles, home appliances, mobile phones, tablets, medical equipment, military products, and even aerospace equipment. In the current application fields of many embedded devices, we urgently need these devices to work more stably to ensure our lives are safe and reliable. For more stable and reliable embedded devices, first, the product needs to be accurate in the design stage, second, the product is accurate and qualified in the manufacturing stage, and third, the product is stable and reliable in the use stage. The most important stage is the product design stage, first of all to ensure the accuracy of the design, and secondly to ensure the maintainability of the product in the later stage. Most product...
