Embodiment Construction

[0039] In order to solve the problems of cumbersome operation process and low system efficiency when operating a flash memory chip, an embodiment of the present invention provides a method for operating a flash memory chip, which will be described in detail below with reference to specific embodiments.

[0040] When using an FME file to operate a flash memory chip, it is necessary to generate a special FME file for each flash memory chip, and the workload is large. The flash memory chip operation method provided in the embodiment of the present invention realizes that a plurality of flash memory chips share a common program. When operating a specific flash memory chip, it is only necessary to change some specific configuration parameters of the general program to obtain the executable program of the flash memory chip.

[0041] Embodiment 1 of the present invention will be described below with reference to the accompanying drawings.

[0042] First introduce the network system u...

Abstract

The invention discloses a flash memory chip operation method which relates to the field of electron and solves the problems of troublesome operation process of generating an FME file and low system working efficiency when a flash memory chip is operated by the FME file. The method comprises the following steps: a supervisory computer obtains the configuration parameter and the general program of a flash memory chip according to the type of the flash memory chip; the supervisory computer modifies the general program according to the configuration parameter and obtains an executable program of the flash memory chip; and an on-chip system executes the executable program on the flash memory chip. The technical scheme is suitable for operating the flash memory chip in an embedded system.

Description

technical field [0001] The invention relates to the operation of semiconductor storage, in particular to a flash memory chip operating method, an online emulator and a flash memory chip operating system. Background technique [0002] System on a Chip (System on a Chip, SOC) is one of the popular directions in the field of embedded applications. The system on chip is connected with several flash memory chips for storing data. When reading, writing and erasing a flash memory chip connected to a system-on-chip, the debugger needs to modify the example file used to describe the operation according to the configuration parameters of the flash memory chip to obtain the An example file matching the flash memory chip, and then write a program for operating the flash memory chip according to a preset template, and then combine the example file and the program to generate an FME file (Flash Method File, flash memory method file), in the FME file It includes the program that can read...
