Introduction

Ethernet allows user to remotely upgrade firmware without having a physical connection between the Micro AI device and computer.

Prerequisites

• PC with following software Installed
  • Python 3.9 with requests library
  • To Install Python:
    • Open Command Prompt
    • Install Python 3.9 by running “python 3” (If Python is already installed skip to step ##).
    • This will open Microsoft App Store
    • Install Python 3.9
      1. Install the Python ‘requests’ module by running

    • pip3 install requests

• Micro AI Firmware to be loaded in .bin format
• IP address of device (see Quick Start Guide if you do not have it)

Updated Micro AI Firmware

1. Ensure that the Micro AI is connected to Ethernet
2. Place the firmware *.bin and the included Python Firmware Upload script into the same directory.
3. Open Command Prompt
4. Navigate to the folder where the .bin and fw_upload.py files are located with “cd”
5. In Command Prompt run the command:

python3 fw_upload.py --ip <IP Address> --fw rtcam.bin

The Micro AI will restart, wait until “Update accepted!” is displayed on the command prompt

Response from RTCAM: {"block":359}
Upload: 100.0000%

Response from RTCAM: {"reply": "success"}
