[0002] If a fatal exception occurs during the operation of the software in the embedded processor, the processor will be shut down, resulting in the failure of the control terminal software to access, and the debugging information on the processor cannot be obtained
Especially in the official product operating environment that is separated from the hardware emulator, when the embedded processor is down, there is no means to obtain the software operation record of the processor, and it is not easy to analyze the cause of the processor downtime
[0003] The usual downtime processing flow is as follows: figure 1 As shown, in this process, the reset of the processor destroys the first operating site during the downtime, and it is impossible to analyze the cause of the abnormality; and this process often requires a large number of test versions to try to locate the problem

Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0019] figure 2 , is a schematic flow chart of the first embodiment of the processing method for embedded processor downtime of the present invention, the method comprising:
[0020] Step S11: software survival detection.
[0021] In this step, the software module sends a software request from the control end to the detected processor based on the mode of request→response, and requires the processor to respond.
[0022] In this step, after the control terminal s...

Description
technical field [0001] The invention relates to the field of embedded systems, in particular to a method for jointly detecting and processing an abnormal downtime of an embedded processor based on hardware and software. Background technique [0002] If a fatal exception occurs during the operation of the software in the embedded processor, the processor will be shut down, causing the control terminal software to be unable to access, and the debugging information on the processor cannot be obtained. Especially in the formal product operating environment separated from the hardware emulator, when the embedded processor is down, there is no means to obtain the software operation record of the processor, and it is not easy to analyze the cause of the processor downtime. [0003] The usual downtime processing flow is as follows: figure 1 As shown, in this process, the reset of the processor destroys the first operating site at the time of downtime, and it is impossible to analyz...
