Part 1 Quick Start

This part of content and operation, it takes about half a day to read and complete the first time
1. After getting the development board, the first thing is to prepare for using the development board. It is necessary to install terminal software. Open 《Terminal Software Reference Manual》 and refer to Software Download and Installation to install the terminal software.
2. After the terminal software is installed, open 《Startup Manual》, and start the development board with reference to the document.
3. After the development board is successfully started, refer to 《linux-4.14.98 Programming Guide》 《ANDROID9.0 Burning Instruction Manual》 Perform a burn. The purpose is to familiarize yourself with the programming operation and prepare for the next step of functional verification.
4. After the development board is burned, open the corresponding [Test Manual] and perform a test to verify that the development board functions properly.

Part II Basic Software Development Guidelines

This part of content and operation, it takes about half a day to read and complete the first time
1. First of all, to develop software, you need to set up a development environment. You will encounter various problems when setting up an embedded development environment. In order to avoid wasting unnecessary time and energy, we recommend using our virtual machine here. surroundings. Open 【Development Environment Guide】 and configure the virtual machine by referring to the document.
2. After the development environment is set up, you should refer to [Compilation Manual] to compile once, and keep the compiled object files.
3. After compiling the object file, update the object file to the device, and it is best to refer to [Test Manual] to perform another test to verify that there is no problem in the compiled object file.

Part III Advanced Software Development Guide

After completing the Quick Start for Using the Development Board and the Basic Guide to Software Development, we are already familiar with the basic things. So, the next step is what you need to know about secondary development.
