Method and device for detecting EEPROM read and write functions

Abstract

The invention provides a method and device for detecting EEPROM read and write functions. The method comprises the steps that after a printed circuit board (PCB) of a product is assembled, a storage space of an EEPROM on the PCB is obtained, read and write function detection is conducted on the storage space of the EEPROM, and after detection succeeds, an application program facing a market is downloaded on the product. Accordingly, due to the fact that detection on the read and write functions of the EEPROM is conducted before the product downloads the application program, after the EEPROM read and write functions are verified successfully, the application program facing the market can be downloaded on the product and put into practice, and then the problem that in the prior art, when theread and write functions of the EEPROM of finished products or the products applied by facing the market are detected, and when the read and write function problems occur in the EEPROM, due to repairing or scrapping, the product cost is increased can be avoided.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and a device for detecting EEPROM read and write functions. Background technique [0002] Electrically Erasable Programmable Read-Only Memory (EEPROM for short) is generally used to save important user data, that is, non-volatile data. EEPROM is a memory chip whose stored data is not lost after power failure, and is a plug-and-play memory. When users use it, they can erase the existing information on the EEPROM online, and can also update the information on the EEPROM in real time. For example, use the EEPROM to store the number of power-on times of the vehicle. Every time the vehicle is powered on, the EEPROM can add 1 to the number of power-on times, and the power-on times recorded on the EEPROM will not be lost after the vehicle is powered off. When the vehicle is powered on again, the EEPROM will continue to add 1 to the power-on times. [0003] At present, many...

AI Technical Summary

Problems solved by technology

In the process of testing the read and write functions of the EEPROM of the finished product or the product that has been applied to the market, when it is detected that there is a problem with the EEPROM, it is necessary to return the finished product or the product that has been applied to the market to the factory for repair or Scrapping and returning to the factory for maintenance will inevitably bring about a large repair cost, and scrapping will inevitably cause waste of resources and increase the cost of the product
