Getting started with Intel Edison
Procedure based on Yocto Complete Image 3.5 with Linux laptop, using non-Arduino Intel Edison Mini Breakout board model EDI1BB.AL.K
Add your username to the appropriate groups on your laptop
adduser $(whoami) dialout
adduser $(whoami) plugdev
Logout and login on your laptop (reboot not required). On laptop:
dmesg
messages will stream to the laptop from Edison once it’s powered on.
Connect to Intel Edison via two microUSB Type B cables. Micro-USB type B are the common connectors everyone uses for phones etc.
Edison jack | Purpose |
---|---|
J16 (OTG) | Powers the Edison, mounts 805MB FAT32 partition Edison |
J3 | internal serial to USB converter |
Assuming Edison comes up on laptop as /dev/ttyUSB0
when both J16 and J3 are connected,
screen /dev/ttyUSB0 115200
Or use PuTTY.
Press Enter for login prompt. Login as root
. There’s no password unless you set one previously.
See notes at bottom of this page for connection troubleshooting.
Software Update
It’s handy to be connected with PuTTY to the Edison, to see a much more detailed progress report.
Note this procedure erases everything on the Edison including data and configuration settings
On laptop, download latest Yocto Poky Complete Image. On laptop:
apt install dfu-util
Extract the Poky Complete Image, and from the extracted directory:
./flashall.sh
If you get a message
otaupdate.scr not found
upon Edison rebooting, the update is probably not going through. The process will take about five minutes (much longer than a normal reboot).
Confirm the proper version is uploaded by typing on Edison
cat /etc/version
201606061707
and at login you’d see with Yocto 3.5:
Poky (Yocto Project Reference Distro) 1.7.3
The Edison used space upon Yocto install was 76%. 319 MB free of 1.4 GB on a 2 GB Edison.
df -h
Intel Edison Configuration on first startup
from PuTTY window connected to Edison:
configure_edison --setup
Intel Edison Wifi can connect to WPA2 Enterprise as well as typical home WPA2 access points.
Unofficial Intel Edison Repository
On the Edison, add to /etc/opkg/base-feeds.conf
src/gz all http://repo.opkg.net/edison/repo/all
src/gz edison http://repo.opkg.net/edison/repo/edison
src/gz core2-32 http://repo.opkg.net/edison/repo/core2-32
Update repo cache
opkg update
The core2-32
opkg directory holds programs commonly used.
Troubleshooting
Both (two) green LEDs on the breakout board must be on and steady. If they are cycling on and off every several seconds, your USB port may not be providing enough power to J16. Maybe that USB cable is bad.
- Alternatively, the Edison eMMC flash memory could be corrupted, which requires reflashing
On laptop, unplug and plugin both USB cables, then type
dmesg
you should see
New USB device found, idVendor=8087, idProduct=0a99
FTDI USB Serial Device converter detected
Detected FT232RL
FTDI USB Serial Device converter now attached to ttyUSB0
If not, try being sure you are NOT plugged into a USB 3.0 port (has SS logo or blue colored inside). Try swapping cables at the Edison end–maybe one of them has the pins a little worn out. Poweroff and Power on your PC. Try another PC. If you don’t see these lines output by dmesg
upon plugin, no other steps will work. You have to fix this first.
Type in your laptop
lsusb
you should see a line with
ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Type in your laptop
ls /dev/ttyUSB*
you should see
/dev/ttyUSB0
