ARTIFACT // PI5-HAILO-NPU-CHECK.SH (SHELL)

Raspberry Pi 5 AI Kit (Hailo-8L NPU) PCIe Gen3 & Thermal Verification Script (pi5-hailo-npu-check.sh)

Checks PCIe bus enumeration, HailoRT firmware alignment, NPU device temperature, and throttled status before running vision+LLM pipelines.

[KEY VERIFIED TAKEAWAY / TL;DR]This reproducible configuration artifact "Raspberry Pi 5 AI Kit (Hailo-8L NPU) PCIe Gen3 & Thermal Verification Script" (pi5-hailo-npu-check.sh, SHELL) is paired with Tinker AI Lab's hardware-verified guide "pi5-hailo8l-npu-vs-cpu-vision-benchmark". It exposes 2 customizable browser variables (PCIE_SPEED_HINT=3, EDGE_LLM_MODEL=qwen2.5:3b) with loopback-first security defaults.

Camera frames are processed in real time on the local Hailo-8L NPU; zero video streams ever leave the device.

Known Operational Limits & Failure Modes
  • Crucial hardware boundary: The Hailo-8L M.2 NPU (13 TOPS) accelerates CNN/Vision models compiled to `.hef` format (YOLO, ResNet, Pose); it CANNOT accelerate Ollama GGUF language models (`qwen2.5`, `llama3`).
  • However, offloading object detection to the Hailo-8L NPU frees ~82% of the Pi 5 Cortex-A76 CPU cores so Ollama can run a 3B LLM simultaneously without thermal throttling!
DEPLOYMENT CHECKLIST // 配置落地核验步骤

3-Step Verification Checklist After Deploying pi5-hailo-npu-check.sh

  1. Confirmed `lspci` lists `Hailo-8L AI Processor` and `hailortcli fw-control identify` succeeds.
  2. Enabled `dtparam=pciex1_gen=3` in `/boot/firmware/config.txt` and rebooted.
  3. Added frame confidence & cooldown debouncing before triggering the CPU Ollama model.
