Why use linux for embedded

Reasons: 1. Linux supports a rich network protocol stack. Regardless of whether the embedded project requires WiFi, mobile broadband or Ethernet connection, Linux supports system network services such as NetworkManager; 2. Modularization, by combining several The software packages are combined together to form a Linux operating system stack, which can be customized by embedded developers for any purpose; 3. High security, which can ensure the safety of embedded projects; 4. Rich drivers can be provided, It also enables parallel development of drivers and applications to speed up development.

Linux is an open source operating system. It is more and more widely used on embedded device platforms. It can be said that embedded Linux is a direction for the development of embedded technology and a banner of embedded technology.

As the cost of hardware continues to decrease, some more complex embedded devices generally use the embedded Linux operating system and develop on the embedded Linux platform, which can greatly improve the efficiency of embedded development. , improve system stability and reliability, and reduce development costs.

The reasons why embedded Linux is used

1. Network

We all know very well, Network capabilities are available out of the box in most consumer products. Fortunately, Linux supports a rich network protocol stack. Whether your embedded Linux project requires WiFi, mobile broadband (WWAN), or Ethernet connectivity, system network services such as NetworkManager are supported on Linux.

2. Modularity

By combining several software packages together to form a Linux operating system stack, embedded developers can Customize it.

3. High security

Linux systems rarely run anti-virus programs. The permissions model is more secure, with default users being granted minimal permissions. Considering the large number of Linux distributions, developing a virus that works on all versions of Linux is not an easy task.

4. Open source is free and the community is active.

Open source is one of the reasons why many small companies use it. It does not involve patent and property rights disputes.

Freely available, community-maintained build systems such as Yocto and Buildroot enable developers to create custom Linux distributions for most hardware architectures. Unfortunately, various challenges not addressed by community projects are bound to surface when delivering embedded Linux in production. However, this gap can easily be filled by embedded Linux vendors, who offer enterprise-grade support and expertise, significantly reducing time to market.

5. Linux is fully functional

There are rich drivers for many embedded hardware devices. They only need to be transplanted and do not need to be changed too much. In addition, Linux can enable parallel development of drivers and applications, speeding up development.

6. Linux has a tailored chip configuration file

For most chips, there is a tailored configuration file. Under the Linux kernel source code, arch/arm/ There are many chip configuration files in configs.
