Installation & First Inference

Prerequisites

Requirement	Details
GK7206 board	Pre-flashed with working NPU driver
SD card	Inserted, formatted as FAT32
Ethernet cable	Board connected to public network
Power cable	Powering the board

Board default IP: 192.168.49.10
SSH login:

ssh root@192.168.49.10
# Password: 123456

Verify NPU is ready:

ls /dev/npu.0
# Output means it's ready. No output — contact support to reflash firmware.

SD Card Mount

Insert the SD card (FAT32 format) and mount it:

mount /dev/mmcblk1p1 /mnt

If you see No such file or directory, the SD card device may be mmcblk0p1. Use ls /dev/mmc* to verify. Run df -h to check mounted devices — if the SD card appears, the mount was successful.

Download AI Inference Tools from ShimetaPi Repository

wget https://mirrors.shimetapi.cn/repos/GK7206/install.sh -O - | sh

Once you see 安装完毕 (Installation complete), continue:

. /mnt/setup.sh
# Activate the environment

First Inference: Image Detection

The installation includes a YOLOv8n COCO demo model and test image. Run this to verify the tools are working:

. /mnt/setup.sh
shimeta_infer /mnt/yolov8n_demo.zip /mnt/people.jpg

If you see detection results, inference is working correctly.

Download the Inference Result Image
