LCSC-TaishanPi-3M-RK3576 Qt 5.15 Development Guide

This guide focuses on Qt 5.15 embedded application development on the LCSC-TaishanPi-3M-RK3576 development board. If you need to compile system images or learn about low-level driver development, please refer to the corresponding system development documentation.

Prerequisites

Step	Description	Reference
1. Flash system image	Use RKDevTool to flash the Buildroot image to verify the download environment is intact	System Flashing
2. Set up VM environment	Install VMware + Ubuntu 22.04 on Windows 11	VMware Ubuntu Setup
3. Obtain SDK	Download the SDK in the Ubuntu VM	SDK Setup
4. Verify serial connection	Confirm serial communication at baud rate 1500000	Serial Debugging
