NPU Environment Setup

The NIO 12L is powered by the MediaTek MT8395 (Genio 1200), which integrates an APU (AI Processor Unit) and AI Accelerator (Aia). You can use the NeuroPilot software stack on Ubuntu to access hardware acceleration for AI inference.

Install Firmware and Runtime

First, install the APU firmware and Neuron runtime:

sudo apt install mediatek-apusys-firmware-genio1200
sudo apt install mediatek-libneuron mediatek-neuron-utils mediatek-libneuron-dev
sudo reboot

Install Neuron SDK

After rebooting, install the Neuron SDK:

Device

snap install mtk-neuropilot --edge

The --edge channel publishes the latest packages, which may update more frequently than the stable channel. For stable production use, check the Snap Store for each channel's version and support status.

Verify Installation

vpu5_test

sudo vpu5_test -a ks -l 10

The result should show PASS.

ncc-tflite

ncc-tflite is a command-line tool for converting models from tflite format to dla format:

Device

ncc-tflite --help

neuronrt

neuronrt can run dla models to verify model integrity:

Device

neuronrt -v

Run Benchmark

sudo mkdir -p /usr/share/benchmark_dla
sudo cp /usr/share/neuropilot/benchmark_dla/* /usr/share/benchmark_dla/
sudo apt install python3-pip
sudo pip3 install numpy
sudo python3 /usr/share/benchmark_dla/benchmark.py --auto

Supported Model Formats

• TFLite (.tflite)
• ONNX (.onnx) — requires loading via the Neuron API
• Caffe (.caffemodel)
