AI Technical Summary

Problems solved by technology

However, data cannot be read from RAM while the microprocessor is stopped
So the problem is: Even if you want to store the stored content of RAM, you can't store
When there is no problem in the execution of the process before the reset after the restart, the cause of the exception that stores the error
In addition, the reason is that the cause cannot be determined when the process is earlier than the process before the reset.
In the well-known techniques mentioned above, it is difficult to correctly figure out why the exception occurred

Embodiment Construction

[0019] The present invention can store the content of the memory as a log when an abnormality occurs in the control circuit. Make it easy to analyze the cause of the exception. Below, use Figure 1 to Figure 7 , an example of an image forming apparatus according to an embodiment of the present invention will be described. A description will be given taking the digital multi-function peripheral 100 as an example of an image forming apparatus. However, each element described in this embodiment, such as a structure and arrangement|positioning, does not limit the scope of invention, It is a mere illustration example.

[0020] (Digital MFP 100)

[0021] use figure 1 , the digital multifunction peripheral 100 of the embodiment will be described. Such as figure 1 As shown, the MFP 100 includes a control unit 1 , a storage unit 2 , a document feeding unit 3 a , an image reading unit 3 b , an operation panel 4 , a printing unit 5 , a memory connection unit 6 and a power supply un...

Abstract

The invention provides an image forming apparatus and a control method of the image forming apparatus. When a watchdog reset request is input, a power supply controller performs partial reset processing (resetting of a control circuit alone). When restarted by partial reset processing, the control circuit makes a non-volatile memory store a log of the stored contents of a volatile memory. After the log is stored, the control circuit transmits a system reset request to the power supply controller. Based on the system reset request, the power supply controller resets the control circuit, the non-volatile memory, the volatile memory, and reset targets.

Description

technical field [0001] The present invention relates to an image forming apparatus that collects logs when an abnormality occurs. Background technique [0002] Systems exist that contain microprocessors. Sometimes the microprocessor stalls due to noise or a software bug. Sometimes the entire system stops due to a stop of the microprocessor. Sometimes use the monitoring timer (Watch Dog Timer) to automatically restore the stopped system. An example of a recovery manner using a watchdog timer as described below is known. [0003] Specifically, it describes an automatic fault recovery method that executes error history storage processing: using a microprocessor, a watchdog timer detects and initializes a runaway of the system, stores the operation history of the software, and uses a watchdog timer flag to detect The watchdog timer has been activated, divide the software into functional modules and control its actions, use the restart flag to detect that error processing has...
