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

data storage operations in the device driver, but to consider the data processing congestion, do not affect the Serversuperio device-driven overall scheduling.Once you have configured and tested your system using the designer IDE, you can choose to start the console as a runtime environment with the following effects: 1.[serial] "C # communication (Serial and network) framework design and implementat

(For details about the operation on registers, see the LCD section of the S3C2440 Data Manual) Lcdcon1: 17-8-bit clkval6-5-bit scan mode (for the STN screen: 4-bit single/double scan, 8-bit single scan)4-1-bit

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. To write a Linux driver:Step 1 : Build a linux

on the attribute file. (This is shown in the following example)1.2 kset Kset is a container with all kobject objects of the same type, which is equivalent to a floor of the building. Struct kset {struct list_head list; // The same type of kobject linked list spinlock_t list_lock; // struct kobject kobj; // The kobject object struct kset_uevent_ops * uevent_ops; // action function for notifying the Event}; struct kset_uevent_ops {// call function 1 an

The experiment in this chapter will realize the real Linux driver, which will realize the direct interaction with the hardware. 4 LED lights need to be controlled . the implementation principle of 7.1LED driveIn fact, it is not the Linux driver that writes data directly to the memory in the hardware, but interacts with the native I/O memory. I/o Memory is a mapping of hardware in host memory that is conn

1. Use Files in the driver In Windows, an object is represented by a file object, which is an object managed by the object manager. For example, a directory is also represented by a file object. The kernel component uses an object name to reference a file.\ DosDevices. (In Windows 2000 and subsequent operating systems,\??Equivalent\ DosDevices). For exampleC: \ WINDOWS \ example.txtObject Name\ DosDevices \

requirements.Android HAL Architecture. The rationale is to use the library (. so file) in the Android system to invoke Linux drivers located in kernel space (typically accessed through device files). The android application (apk file) can then access the library in the HAL through the NDK program, or access the library in the HAL directly from the Android application. The new version adds the entry code for the HAL schema that is required by the HAL architecture.Added HAL for LED
