This article will explain in detail how to use rt-smart on raspberry pie 4. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1. Preface

As the open source of rt-smart source code is approaching, its true face is also gradually emerging. This article mainly shows the effect of rt-smart on raspberry pie 4.

two。 Environment building

There are two aspects needed: hardware environment and software preparation, and the process is relatively easy.

2.1 hardware preparation

1. Raspberry pie 4B

2. SD card (below 32GB or 32GB)

3.USB to TTL Serial Port Line

4. Network cable

5.TYPEC (Power supply)

6. Card reader

Network cable is used for network data transmission and convenient debugging, if there are no network conditions, it can only be plugged in and unplugged SD card every time, so it can also be developed, but the efficiency is relatively low.

Connect serial port line

After the above tools are ready, you can connect the serial port line to the development board. The connection diagram is as follows:

2.2 Software preparation

1. Download boot file from raspberry pie SD card

Some boot files need to be put into the SD card due to the loading of raspberry pie. You can download it at the following address

Link: https://pan.baidu.com/s/1gvJInzKzPB8PNeoYrIvYCw

Extraction code: bnd7

When the download is complete, unzip the file and put it in the SD card.

The compiled executable file is stored in the bin folder, and kernel7.img is the kernel of rt-smart on raspberry pie 4. Put the file into the empty SD card, plug it in, open the serial debugging assistant, and you can see that the program is running normally.

Heap: 0xc00c9a12-0xc40c9a12
