Abstract

The invention provides a debugging system and a debugging method for an embedded system of a production phase. The debugging method comprises the following steps: when compiling and connecting are carried out, a production system binary file for releasing is generated and simultaneously a binary dynamic code file used for debugging is also generated by use of debugging codes; when a release build binary file is generated, the debugging code in the code is not included, and any dummy instructions, call instructions or stub code cannot be generated, and when a binary file for debugging is generated, corresponding debugging point address information is also generated and included; when the debugging system runs, a dynamic instruction loading tool lists all of the debugging point lists; a user selects or changes the required debugging point as required; and finally, the dynamic instruction loading tool loads and runs the corresponding debugging code of the debugging point designated by the user through dynamically modifying the running release build software.

Description

technical field [0001] The present invention relates to the debugging technology of the embedded system, more specifically, to the debugging system and the debugging method of the embedded system in the production stage. Background technique [0002] In the development stage of the embedded system, the debugging and debugging (DEBUG) system is usually used, which can output debugging information related to the operation of the embedded system, including execution context, variables, registers, memory stack, etc. Debug information can be output on the system console or saved in the debug log for later analysis. For the production stage of embedded systems, due to the performance and memory overhead of the debugging system, the debugging function is usually removed in the product release version. [0003] In the prior art, monitoring and debugging code is sometimes included in embedded systems, even in release versions, where the product specification allows, in order to pres...
