Technical Field

The invention relates to the technical field of flash memory testing, in particular to a method for testing power failure pressure of a flash memory storage device.

Background

In the case of using a flash memory storage device as a system storage device platform, part of the open source platforms can be powered down through a power down device of the bottom control platform, but the power down device of the bottom can not be controlled after the system is installed.

In the prior art, a power-down device is designed as an independent device for timing power down, a loading system is required for timing control, flash memory is used as a power supply of a system storage device platform, the device is similar to a microcomputer, but whether a system loaded by the flash memory storage device is hung or not cannot be judged, so that a tester cannot timely know when the system is hung.

At the end of the development of the flash memory device, the flash memory device needs to be placed on a platform capable of loading a system as a memory, stability verification is performed on the flash memory device loaded with the system, one of the verifications requires unexpected power down of the platform, indirectly and continuously unexpected power down of the flash memory device to ensure the stability of the system loaded by the flash memory device, when the test is carried out, a large number of repeated power failure pressure tests are needed, and whether a system arranged on the flash memory storage device is started successfully or not is needed to be judged, the process can be up to ten thousands of times, the time required for each time is about 1 minute, if the manual power-on and power-off test needs to consume huge manpower, the existing automatic power-off device can only power off, a system loading the flash memory storage device cannot be judged whether to be hung or not, and the purchase cost is high.

Disclosure of Invention

The invention aims to provide a method for testing power failure pressure of a flash memory device, which aims to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: a power failure pressure test method for a flash memory device comprises a PC, a simple power-off device and a platform, wherein the PC is connected with the simple power-off device through a USB, the simple power-off device supplies power to the platform through a power output line, and the platform is connected with the PC through a serial port, a USB or a network cable.

Preferably, the method for testing the power-down pressure of the flash memory device comprises the following steps:

A. running designed PC control software;

B. clicking to start after the number of times of the expected test is set;

C. the software checks the current test times, stops the test if the target times is reached or the system is hung up, and continues to send a power-off command to the simple power-off device if the target times is reached;

D. the platform is started after the power-on device provides power for the platform;

E. the platform is powered on and started, and logs are continuously printed to the UART serial port, or the platform is successfully started to process a command sent by PC software;
