First, build the kernel source code tree. I am using the friendly arm comes with Linux source code: linux-2.6.35.7-20120912.tgz
First copy the kernel source code linux-2.6.35.7-20120912.tgz to the Ubuntu system directory/home/liuhui8989/linuxshare
Unzip: Tar zxvf linux-2.6.35.7-20120912.tgz to get the linux-2.6.35.7 folder.

If the system needs to be re-installed in case of a computer failure, if the random drive disk is lost, such as the motherboard driver, NIC driver, and graphics card driver.
In particular, some old machines, motherboard integrated Nic, graphics card. Even if Win2000/WINXP is installed, some devices cannot be automatically driven.
In this case, we can consider u
The ADCTSC registers are shared between the ADC Driver and the touch-screen driver. How can one register be used when processing them? -- Linux general technology-Linux programming and kernel information. The following is a detailed description. You guys give me directions

Driver support routines (driverProgramDevelopment support routine)
Driver support routines are routines that the Windows operating system provides for kernel-mode drivers to use.Drivers do not use Microsoft Win32 routines; instead, they use the driver support routines that this section describes.The
This morning, I am going to play a game similar to running a kart under fedora, but the driver does not support 3D. So I started the Driver Installation trip early in the morning. There are a lot of online materials, but they are not practical, after finding a solution, I will share my experience with you. My uname-R is 2.6.35.6-45. fc14.i686. PAE

Setting up a real-world development environment requires the following steps:1. Declare the application to be debug in the application's manifest file;2. Open the application debugging support;For apps created through Eclipse, you can omit step 2, because debugging support for your app automatically opens when the Eclipse IDE launches the app.Note: In the application development process, to manually enable debugging support in the manifest file, it is best to turn off debugging support before th
The Driver is also known as the Device Driver.
In the modern computer architecture, the operating system does not directly deal with hardware, but communicates with hardware through drivers.
On the same computer, although the devices are the same, the drivers vary greatly due to different operating systems. However, no matter what is similar, it can be summarized into the following three points:

After the examination has passed, Android-driven learning has been broken for more than half a year, and now pick up learning, review the general framework of Android Drive.The core of the Android system is Java, which has a David virtual machine. Android-app operating hardware is also equivalent to Java operating hardware.Operating hardware on a Linux system is implemented via open read Write, which is the operation of C libraries. If Java can directly invoke the function in C library, it will
The general Ubuntu default contains the driver of the Intel graphics card, if not, then determine whether the graphics card is too high, such as the I7 7th generation CPU is not in Ubuntu 16.04, resulting in the screen will be very card, because the Linux 4.4 kernel does not contain Intel HD Graphics 630 driver, the workaround is only to upgrade the Linux kernel to 4.7 in Ubuntu 16.04.The following are two
This digest from my my book fixing "embedded Linux driver template explaining and project practice"Initially it seems that Linux device driver development involves a lot of content, and the need to achieve a wide range of drivers, in fact, after a period of time to drive back looks like the main points are:(1) Classification of the drive, first summed up as which type of drive, the collation of the correct
After discussing the initialization and deletion of drivers for I2C devices and I2C adapters, we will focus on several function operations in file_operations, paste the file_operations struct code first. Let's see which functions are included.
Static const struct file_operations i2cdev_fops ={
The structure must be quite clear. Therefore, the I2C Driver provides the following operation functions for the user space:
1. no_llseek
2. i2cdev_read
3. i2c
Currently for driver developers are often faced with a problem--windows 10 drive digital signature problem, according to Symantec VeriSign Code signature China agent Shenzhen yi-dimensional letter customer service, the current issue of Symantec CodeSign also does not support Windows 10, the digital signature certificate for foreign countries already has an EV version of CodeSign, and temporarily does not support the Chinese version of the EV CodeSign.

The BS System Using C # + ODBC has no problem in vs2005, but it will appear after it is released"Error [im002] [Microsoft] [ODBC driverProgramManager] No data source name found and default driver not specified"Error, the problem is that the type created by DSN is incorrect.

2. convert a physical address to a virtual address
In the program, we can only use the converted virtual base address and register offset to access the corresponding register, instead of directly accessing the physical register as the bare board program, so the physical address must be converted, the following is an example.

To reinstall ODBC, follow these steps:
Use odbcconf.exe to re-register the ODBC driver.
There are several script files in the Windows/system32 directory to complete the driverProgramRegistration:

At the end of the norflash driver load, there are several statements: If (ezkit561_mtd) {ezkit561_mtd-> owner = this_module; return handler (ezkit561_mtd, ezkit561_parts, ezkit561_part_count );} use add_mtd_partitions (Drivers/MTD/mtdpart. c) The function can add corresponding partitions to the partition table of the system. In this way, when you need to read and write the partitions, you can find the corresponding MTD and call its function to complet
