I started this minimal project to re-use the arduino board setup from TCup (with Grove LCD display and thermometer), and make sure that it would run automatically when I plug my Intel Edison board.

Findings

I ended up spending a lot of time making sure that it works properly on startup.

Initially, I was downloading the project's files to /node_app_slot/ (which seems somewhat linked to /home/root/.node_app_slot/, for some reason), so that Intel's XDK would automatically run it on startup. It did, but the text was blinking/flickering on the screen, making it almost not readable.

After hours of research, I realized that:

  • The same problem happens if I setup a systemd service instead of relying on XDK daemon for running the script on startup.
  • But I finally solved the problem by setting the service's TimeoutStartSec parameter to 20 seconds.

Setup

In this section, I'm keep some instructions to remember how to make it work again later:

  1. Plug both USB cables between Edison and the computer
  2. Connect to Edison's terminal by
  • finding its “usbserial” device name: ls /dev/tty.*
  • connecting to the device: screen /dev/tty.usbserial-A102GW3T 115200
  • logging in as root
  • keeping these shortcuts in mind:
    • Cancel/exit a command: Ctrl-C
    • Disconnect: Ctrl+A then Ctrl+\
  1. Initialize Edison's connectivity
  • full setup: configure_edison --setup
  • only wifi: configure_edison --wifi
  • get IP address: configure_edison --showWiFiIP or ip a
  1. After having setup a password for the root account, connect to ssh server through Wifi (the second USB cable does not longer need to be plugged):
  1. Push/download the program to Edison, from computer:
  • ./push.sh
  1. Initialize and run the program on Edison:
  • cd thermometre
  • npm install
  • node main
  1. Make it run automatically on startup:
  • ./install_service.sh
