Today, I would like to talk to you about how to minimize the installation of Linux in Raspberry Pie 4. Many people may not know much about it. In order to make you understand better, the editor summarized the following. I hope you can get something from this article.

Raspberry pie 4 minimizes installation of Linux1. The purpose of this article

Raspberry Pi 4 Model B has been released for half a year, and its powerful performance and low price make it very popular.

Let's take a look at the main features.

1.5GHz 4 core 64-bit ARM Cortex-A72 CPU (~ 3x performance) 1GB/2GB/4GB LPDDR4 SDRAM memory full throughput Gigabit Ethernet dual-band 802.11ac wireless network Bluetooth 5.0two USB 3.0and two USB 2.0interface dual display support, resolution up to 4KVideoCore VI graphics card, support OpenGL ES 3.xHEVC video 4Kp60 hard decoding is fully compatible with early raspberry pie products

Raspberry pie 4 finally separated the USB from the network card, which used to be the USB card. And the use of Cortex-A72, the main frequency also reached 1.5GHz. Under such performance, it is also very convenient to run all kinds of applications, and more importantly, the price is cheap, which can be worth the configuration of a small computer. Next, write about the process of installing minimized Linux on raspberry pie 4.

two。 Environmental preparation

This experiment is carried out on a win10 computer. When burning raspberry pie firmware, you need to prepare an SD card, at least 8MB. What I have here is an SD card for 32MB.

Then download the raspberry pie software Raspberry Pi Imager, which specializes in burning images, in the following website

Https://www.raspberrypi.org/downloads/

You can choose different platforms to download.

Select the platform of Windows to download.

After the download is completed, the opening effect is as follows

The first option is to select the system, and the second option is to select the SD card.

There are many choices in the system. We choose raspberry pie Raspbian Buster Lite here.

Select the Raspbian Lite package, and the other package is system-wide.

You only need to download about 400m.

Of course, you can also download it from the website.

Https://www.raspberrypi.org/downloads/raspbian/

Select the appropriate version, and then select Use custom to install

3. System startup

After burning the system to the SD card, you can insert the SD card into the raspberry pie 4. Connect the serial port.

The baud rate is 115200.

At this time, you also need to modify the files in the SD card in order to output the print information from the hardware serial port, otherwise, you can not see the output information through the hardware serial port, you can only connect the HDMI to see the output information. This is troublesome without a HDMI screen.

Open the SD card directory and find the config.txt file

Add an enable_uart=1 sentence.

That's all right now.

Connect the serial port and the network cable, open the serial debugging tool, here I use MobaXterm.

After entering the user name and password, you can enter the system normally. After connecting the network cable, the network can be configured normally.

4. Advanced configuration

There are some advanced configurations that can be done through raspi-config.

Sudo raspi-config

You can choose

1. Modify the current user name and password

two。 Modify network configuration

When you manually set the SSID and WIFI passwords, you can see the following options:

3. System setup

4. Interface Settin

5. Summary

There are a lot of things that can be developed in raspberry pie 4, and this article simply describes the installation and simple use techniques. Among them, you need to pay attention to the use of hardware serial port and WIFI. If there is a graphical interface, you can use graphical configuration, much simpler, if not, you need to use the console to select.

After reading the above, do you have any further understanding of how to minimize the installation of Linux in raspberry pie 4? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
