Nand flash Driver kernel implementation analysis process: Analysis code Handler // drivers/mtd/nand/nand_base.c identify nand flash based on nand_chip's underlying operation function and construct mtd_info nand_scan_ident nand_set_defaults if (! Chip-> select_chip) chip-> select_chip = nand_select_chip; // The default value is not applicable if (chip-> program func = NULL) chip-> program func = nand_command; chip-> program _ctrl (mtd, command, ctrl);

Author: wogoyixikexie @ gliet Previously, I heard from my friends about porting drivers under PB to BSP, and even the file system to BSP. -- Haha, It's very advanced. Now I will take the SD card of 2410 as an example. Previously I did not know that the SD card driver would be in the Pb installation file. Let's take a look at the following three posts-2410 large-capacity SD card research. Http://topic.csdn.net/u/20080911/16/111a849c-fd1f-4955-840d-6ddf

OCI: to install the Oracle client, the portability is slightly poor, and theoretically the performance is better Thin: belongs to type4, which is implemented in pure Java and has good portability. Theoretically, the performance is slightly lower. Recommendation: it is best to use thin driver, which is more portable and more standard, with fewer problems. As for the performance, to be honest, thin driver

Android, X Windows, QT, and many other applications support input devices, such as the keyboard, mouse, and touch screen, in Linux systems, or increasingly prefer the standard input subsystem. Because the input subsystem has completed the character-driven file operation interface, the core task of writing the driver is to complete the interface set aside by the input system, with little workload. But if you want to apply it more flexibly, You need to

Character Device Driver: 1. Generally, we use APIs that dynamically allocate device numbers: Int alloc_chrdev_region (dev_t * Dev, unsigned int firstminor, unsigned int count, char * Name ); Dev is a function used for output. After successful call, the first number of the allocated range will be saved. Void unregister_chrdev_region (dev_t first, unsigned int count ); The above function allocates device numbers for

Laptop installed sound card driver error no appropriate Driver to be installed Cause Analysis: There are Realtek and conexant two kinds of sound cards, when the system can not automatically identify the device when there will be an error. Solution: Enter the corresponding folder double-click Setup to install the driver If Realtek's sound card enters the

Linux Device Driver Programming-Linux general technology-Linux programming and kernel information-complex device driver-the following is a detailed description. The complex device drivers mentioned here involve PCI, USB, network devices, Block devices, and so on (strictly speaking, these devices are not in the same concept, for example, they are tied with Block devices by character devices, PCI and USB devi

The biggest feature of Linux devices is that device operations are like file operations. In the application layer, a hardware device is just a device file. Applications can operate hardware devices like operating files, such as open (), close (), read (), and write. Below is a simple implementation of the character device driver test. c # Include Module Analysis 1. initialize the device driver struct Str
