example 1

[0059] When the system crashes and flies, it is difficult to obtain debugging information from the debugger itself. You can use the tracking tool TRACE to locate the problem. Due to the use of a real-time operating system, it is possible to locate the problem to a specific function of a specific task, narrow the search scope, reduce the search time, and improve the search efficiency. Figure 8 Its processing is shown.

[0060] In practical applications, the specific processing includes the following steps:

[0061] 1, such as figure 1 and figure 2 As shown, connect the system;

[0062] 2. The system starts to power on;

[0063] 3. The software TRACE module fills in the traced debugging information according to the structure of the hardware trace module RAM;

[0064] 4. When the hardware TRACE module writes the object ID, it automatically latches the time information of the clock module, the system frame number position stores the system frame number SFN, and the chip nu...

[0072] Under normal debugging conditions, system memory usage is a very important concern, and it is one of the root causes of system crashes. Since the total amount of memory in an embedded system is often very limited, each module should arrange the use of memory reasonably, and must release the corresponding memory after using it. Combine below Figure 8 Analyze memory usage.

[0073] The processing steps in this example are as follows:

[0074] 1, such as figure 1 and figure 2 As shown, connect the system;

[0075] 2. The system starts to power on;

[0076] 3. The software TRACE module will fill in the corresponding items according to the structure of the RAM of the hardware trace module according to the traced debugging information. At this time, the two functions ALLOC_HOOK and FREE_HOOK in the HOOK function will record all the memory application and release information of the current system into RAM, and write the corresponding module task number and information ...

Abstract

The invention discloses a chip maintenance method. The chip maintenance method comprises the following steps: storing test data and test data output time which are output by the test data to a random access memory and / or a flash memory by the cooperation of a software tracking module and a hardware tracking module; and maintaining a chip according to the test data stored in the random access memory and / or the flash memory. The technical scheme can reduce the system overload, enables a recovered system to further approach to a true system, can help designers effectively understand and analyze the whole process of the system and rapidly solve the problems, lightens the workloads of the designers and improves the working efficiency and the development efficiency.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a chip maintenance method. Background technique [0002] At present, chips related to communication systems include system-side chips and terminal-side chips. These two chips are usually more complex and are generally designed as a system-on-chip, including both hardware design and system design. [0003] The system-on-chip system is relatively large, and its design and debugging involve many modules and are very complicated. Moreover, after the chip is cast, if an error is found, it needs to be solved by patching the software. Among them, the necessary parameters (For example, a large number of experience thresholds, etc.) settings should also be continuously updated as needed. [0004] With the development of embedded systems, there are many debugging methods at present, but in summary, there are mainly the following six debugging methods, including: storage moni...
