01 All test programs in this section require the development board to have a Qt environment to run. The provided file system is derived from a Yocto build. We will later organize a separate ported Qt system to facilitate users in porting third-party software. If the user’s file system is not our factory version, please … Read more
01 The Yocto file system supports QT by default. So how do we run our QT programs on the Yocto file system? In this chapter, we will learn how to develop QT programs in a Yocto file system + Ubuntu environment. Note that the development environment is based on “qtcreator-3.5.1” (Ubuntu 16.04.6), and the library … Read more
1. Development Experience The BSP engineers from device manufacturers mainly focus on root filesystem/driver porting/system integration/hardware debugging. It is important to note the distinction from the driver engineers at chip manufacturers. After graduation, the opportunities to write drivers from scratch are few and far between; most of the time, drivers are provided by the chip … Read more
Introduction EMQX is an open-source MQTT message server developed on the Erlang/OTP platform, widely used in the Internet of Things (IoT) field for message transmission and control between devices and servers. This document is based on the NXP i.MX8M Plus ARM processor platform, deploying and testing EMQX by integrating a Docker environment into the Yocto … Read more
Continuing from the last time, the principle of device cloud control. Today, I found something good on CoolAPK, shared by the expert Da Nuo Nuo, which is just right as the device in hand has adb available for us to take a look.The so-called Yocto is not pronounced as “yang le duo” but as “yao … Read more
In embedded Linux development, Buildroot and Yocto are extremely popular build systems, while Qt is a “magic tool” for graphical interface development.
