#rk3568

The journey from a local training environment to real-time inference on embedded hardware can be a complex puzzle. I’ve just documented a complete pipeline for training a custom YOLOv5 model and successfully deploying it on the Rockchip RK3568 NPU.

The Workflow Highlights:

🛠️ Environment Setup: Navigating the specific Python 3.8/3.9 requirements for YOLOv5 and LabelImg on Windows 11. 🏷️ Dataset Engineering: Implementing a clean directory structure and YOLO-format annotation for high-quality training. 🔄 Model Transformation: Converting the PyTorch .pt weights into .onnx and finally into .rknn using the RKNN-Toolkit2 on Ubuntu 22.04. 🚀 Hardware Deployment: Compiling the C++ RKNPU2 demo and optimizing the post-processing headers for high-performance edge inference.

The result? A seamless transition from a standard PC environment to efficient, hardware-accelerated detection on an embedded development board.

🚀 TFTP Flashing Guide for Forlinx RK3568 Development Board

Efficient system flashing is critical during embedded Linux development and debugging. On the Forlinx RK3568 development board, flashing boot.img and rootfs.img via TFTP + U-Boot provides a fast, stable, and hardware-friendly workflow.

🔧 What this guide covers:

✅ U-Boot network environment configuration (MAC, IP, gateway) ✅ TFTP server setup and connectivity verification ✅ eMMC partition layout on RK3568 ✅ Step-by-step flashing of boot.img and rootfs.img ✅ Practical tips for industrial-grade stability and scalability

💡 Why RK3568 + Forlinx?

🔹 Industrial-grade eMMC & power protection 🔹 Dual Gigabit Ethernet for low-latency flashing 🔹 SATA 3.0 & M.2 expansion without reflashing 🔹 Integrated 1 TOPS NPU for lightweight AI at the edge

This approach significantly shortens iteration cycles and is ideal for industrial control, smart devices, and edge computing projects.

⚙️ How to Configure and Port Library Files via Buildroot on the RK3568 Platform

The Rockchip RK3568 is a high-performance, industrial-grade processor featuring a quad-core Cortex-A55, integrated GPU, and NPU. It is widely applied in edge computing, industrial control, and IoT systems requiring high reliability and scalability.

To streamline Linux development on RK3568, Buildroot provides a fast, modular toolchain that helps developers customize and generate embedded Linux root file systems efficiently.

🧩 Buildroot Configuration Highlights 1️⃣ Navigate to OK3568-linux-source/buildroot/output/OK3568/ and run make menuconfig 2️⃣ Use / to search for specific libraries (e.g., Python3) 3️⃣ Enable required packages and save configuration 4️⃣ Recompile Buildroot with ./build.sh buildroot 5️⃣ Flash the generated rootfs.ext2 image to your development board
