嵌入式linux驱动开发基础总结
English Answer：
Embedded Linux Driver Development Basics.
Introduction.
Embedded Linux is a popular operating system for
embedded systems, such as routers, automotive systems, and
industrial control systems. Embedded Linux drivers are the
software that allows the operating system to interact with
hardware devices, such as network cards, storage devices,
and sensors.
Types of Embedded Linux Drivers.
There are two main types of embedded Linux drivers:
Device drivers are responsible for controlling
hardware devices. They provide a software interface that
allows other parts of the operating system to access the
hardware.
Platform drivers are responsible for managing the
resources of a particular platform, such as the memory, I/O
ports, and interrupts.
Device Driver Development.
The following steps are involved in developing a device
driver for Embedded Linux:
1. Identify the hardware device that you want to
control.
2. Read the hardware documentation to understand the
device's registers, interrupts, and other features.
3. Write the device driver code. The code should
include the following functions:
A probe function that is called when the device is
