How to driver bcm43xx wireless Ethernet under Fedora Core 5
Summary:
Hardwar Software: HP Compaq nx632x, Fedora Core 5 (kernel-2.6.22)
This article mainly introduce how to driver bcm43xx wireless Ethernet in the environment above

of the Android NDK; and the HAL source.Configure the download environment for Android source code: 1. Create a directory to hold the download script file. 2. Download the repo script file (for downloading Android source code). 3. Create a directory to hold the Android source code. 4. Initialize. 5. Start downloading the Android source code.Compiling Android Source code:
Android system transplantation and driver development-Chapter 5-Build a test environment for the Development Board and android-based development
The embedded system installed on the Development Board is much simpler than that on the mobile phone, and there are many extended interfaces. It is suitable for testing programs. Here we refer to the Development Board of cloud6410. It is a low-power/cost-effective
1. Background
Sampleblk is a Linux block device drive project for learning purposes. One of the Day1 source code to achieve a minimalist block device driver, the source codes only more than 200 lines. This article mainly revolves around these source code, discusses the Linux block device drive development the basic knowledge.
Developing a Linux driver requires a

These files are called device files or drive files and are saved in the/ dev directory. This design concept makes interacting with L
1. Generally, the driverProgramI/O requests should be processed asynchronously in the context of some unpredictable threads. We use the term arbitrary thread context to describe the context on which the driver does not know (or care about) the context of the current execution of the processor.
2. Windows 2000 uses the symmetric multi-processor model, that is, all the processors are the same, and s
specify all the trap functions. The callback function is registered through the relevant mechanism.5) Write business logic: Any full Linux driver will do some work related to its functionality, and the COM driver will interact with the data at the rate of transfer. The specific business logic is related to the function of the
Operating system through a variety of drivers rely on home and hardware devices, it has shielded a variety of devices for users, drive hardware is the most basic function of the operating system, and provide a unified operation. Device drivers are one of the most basic components of the operating system and are more than 60% in the Linux kernel source program, so familiarity with driver writing is important.The Linux system maps each

1. The bus is composed of an electrical interface and a programming interface. Kernel functions used to access peripherals of Peripheral Component Interconnect (PCI, peripheral device interconnection,Because PCI bus is widely used on desktops and peripherals on larger computers today, and bus is the best supported bus in the kernel, ISA bus is basicallyIt is a "bare metal" type bus.2. Three main objectives of pci: To achieve better performance when da
foot, Q is the data output foot, and C is the clock foot.
SPI is commonly used in four data transmission modes. The main difference is that the output serial synchronous clock polarity (cpol) and phase (cpha) can be configured. If cpol = 0, the idle status of the serial synchronization clock is low. If cpol = 1, the idle status of the serial synchronization clock is high. If cpha = 0, data at the frontend (up or down) of the serial synchronization cl

the Linux system maps each driver into a single file. These files are called device files or drive files and are saved in the/ dev directory. Since most Linux drivers have their corresponding device files, exchanging data with the Linux driver becomes the exchange of data with the device files.

Kset is a container with all kobject objects of the same type, which is equivalent to a floor of the building.
