【Abstract】 The embedded system often uses flash memory to store code and data.Through the driver of MTD(Memory Technology Device)in the embedded Linux,it is to access the MTD devices,such as flash. This paper introduces the framework of the Linux driver and gives a detailed analysis of the architecture and data structures of the MTD device driver.By taking the platform of EBD9315 for example,the paper systematically describes how to develop MTD driver for Nor flash.更多还原
