Problems solved by technology

[0003] In the consumer field and the industrial field, SPI Flash is used on a large scale and in large quantities. During the use, it is necessary to test and burn SPI Flash. The traditional mode is to manually check the chips on the chip when testing and burning. Specific model, and then select this chip model in the test burning system for test burning, so there is a problem of artificially choosing the wrong model, and not knowing how to choose when the model cannot be seen clearly.

Abstract

The invention discloses a method and a system for automatically detecting pins to identify a specific model of SPI Flash, the method comprising: detecting the pin quantity of the SPI Flash chip, and then according to the detected pin quantity of the SPI Flash chip, step by step Read the ID number of the chip by means of power-on test, and match the specific model of the SPI Flash chip in the database, which can realize the automatic detection of the specific model of the SPI Flash chip without artificially checking the specific model of the SPI Flash chip, and then Automatically test and read and write the SPI Flash chip.

Description

technical field [0001] The invention relates to the technical field of SPI Flash, in particular to a method and system for automatically detecting pins to identify specific models of SPI Flash. Background technique [0002] SPI (Serial Peripheral Interface, Serial Peripheral Interface) is a common clock synchronous serial communication interface, and Flash includes serial Flash according to the interface. [0003] In the consumer field and the industrial field, SPI Flash is used on a large scale and in large quantities. During the use, it is necessary to test and burn SPI Flash. The traditional mode is to manually check the chips on the chip when testing and burning. Specific model, and then select this chip model in the test programming system for test programming, so there is a problem of artificially selecting the wrong model, and not knowing how to choose when the model is not clear. Contents of the invention [0004] The present invention provides a kind of method an...
