Back
in August did a write up on how to install Ubilinux on the Intel Edison on a
Windows 7 box http://www.whiteboardcoder.com/2015/08/install-ubilinux-on-intel-edison.html [1]. I focused on using Cygwin to do this, as I
feel if you are going to be fiddling with the Intel Edison you need to get your
Linux shell on.
I
also made a video on how to do it https://www.youtube.com/watch?v=9fYetzNLTnU [2] which turned into a 90
minute monster.
The
biggest pain point was trying to show how to install Cygwin to those who may
never have installed it. I think I have
a better, and much faster, way to do it now.
Recently
I had to redo my Cygwin installation and found a few tools that make life much
easier to set it up. I am going to use
what I learned there to make this a much quicker tutorial (which I will
hopefully turn into a much quicker video).
Also I am going to be using Sparkfun Intel Edison block instead of the
Arduino Breakout Kit.
Edison Set up
I
purchased an Intel Edison and a 'Base'
SparkFun Intel Block https://www.sparkfun.com/products/13045 .
I
also bought a 'GPIO' SparkFun Intel Edison Block https://www.sparkfun.com/products/13038 . So Can connect it up and blink a light J
Cygwin
What is Cygwin?
It's a Unix like command -line interface for windows. It's maintained by the good people at
RedHat. It's not pure Linux but it's as
good as we get on the Windows platform currently.
Installing Cygwin
How do you install and set up Cygwin for the first time?
Head over to https://www.cygwin.com/
[3] to download Cygwin.
Click Install Cygwin
Click on setup-x86_64.exe To download the program.
After it downloads click and run the program.
If you get this warning just click Run.
Click Next
Select Install from Internet
Click Next
I leave the Root Directory as default.
Click Next.
Click Next.
Click Next
Select a Mirror site and Click next
It starts to download.
Don't bother with additional packages just click Next.
Click Next
Let it download
Checkbox Create icon on Desktop and Click Finish
Other Libraries
Now we need to install some other tools in Cygwin. You could open the Cygwin Package manager and
find each one you need and checkbox it and install them all, but that takes a
long, long time. That is what I did
last time and it took up a lot of the time.
Here is a list of tools you need/are nice to have.
- autoconf
- automake
- bzip2
- crypt
- curl
- diffutils
- gcc-core
- gcc-fortran
- gcc-g++
- git
- git-completion
- less
- libusb1.0 / libusb1.0-devel
- lynx
- make
- nano
- ncurses
- openssh
- perl
- pkg-config
- ping
- python
- rsync
- run
- screen
- tree
- unzip
- vim
- wget
- zip
This list of tools is more than the minimum list you need to
install Ubilinux. It includes several tools you will probably find you need in
the future as you play around with the Intel Edison.
It is possible to install all of these in one shot using the
DOS prompt to run the Cygwin setup you tool you downloaded.
Open a DOS prompt
Right click on the Start icon and search for
"cmd" then run cmd.exe
Assuming the setup-x86_63.exe is in your Downloads folder
run this command from you DOS prompt (copy and paste it in)
|
> %HOMEPATH%\Downloads\setup-x86_64.exe
-q -P autoconf,autoconf2.1,autoconf2.5,automake,automake1.15,bzip2,crypt,curl,diffutils,gcc-core,gcc-fortran,gcc-g++,git,git-completion,less,libusb1.0,libusb1.0-devel,lynx,make,nano,ncurses,openssh,perl,pkg-config,ping,python,rsync,run,screen,tree,unzip,vim,vim-common,wget,zip
|
It
starts to install all the libraries you listed
(this may take a while)
When
it is done you should see this message
Start Cygwin
You should have a Cygwin Shortcut
on your Desktop.
Double Click it to open it.
And it's running.
If the font is too small to read
(for me it is). Here is how to adjust
it.
Right click on the window bar and
click Options.
Select Text and click Select
Select a bigger font and click OK.
I use a the Lucida Sans Typewriter
font at 22.
Click Save
Now I can read it J
Drivers and Software
Head over to
(This page could move or be re-directed, the main idea is to
find the USB drivers for Edison)
Download "Windows Standalone Driver 1.2.1"
After it downloads click on the installer.
If you happen to get this prompt, click Run.
Click Next
Agree to License
Click Next
Click Install
Install starts
click Install
Click Install
Click Install
Click Install
And it's done click OK.
Click Finish
Plug it in
Plug the Edison into the Sparkfun Base block and plug a USB
cord in the OTG side and plug it into your computer.
If the Edison has Yocto Linux Installed, the default Linux,
you should see an extra drive get mounted.
There it is on mine.
It shows up as a drive named Edison.
Yocto Linux allows the Edison to act as a USB thumb drive as well as be
Linux. Ubilinux does not have this
feature.
Installing dfu-util
Open up a Cygwin terminal
Run the following commands to install the dfu-util tool
|
> git clone
git://git.code.sf.net/p/dfu-util/dfu-util
> cd dfu-util
> ./autogen.sh
> ./configure
> make
> make install
|
Then to test run
|
> dfu-util -l
|
Wahoo it's working!
Install Ubilinux
Open up http://www.emutexlabs.com/ubilinux
[5]
Right click on "Ubilinux for Intel Edison" And
select Copy Link Address.
In my case I copied
Note: 150309
translates into 03/09/2015. This is the
latest version as of 3/8/2016 a few details about this release can be found at http://www.emutexlabs.com/blog/225-new-ubilinux-for-intel-edison-released
[6] Looks like they added git and mraa J
Open up a cgywin terminal
I am going to create a folder called Ubilinux go into that
directory and download the Ubilinux file from the link I copied earlier using
the wget command.
|
> mkdir ubilinux
> cd Ubilinux
> wget http://www.emutexlabs.com/files/ubilinux/ubilinux-edison-150309.tar.gz
|
The download may take 15-30+ minutes.
It may take a while to download depending on their server
speed. Several months ago it took 15+
minutes…
For some reason today it took 21+ Minutes to download
Extract the contents of the file by running the following
command.
|
> tar -xvf ubilinux-edison-150309.tar.gz
|
This will extract all the files in a folder called toFlash.
Unplug the Edison.
Cd into the toFlash directory and run ./flashall.sh
|
> cd toFlash
> ./flashall.sh
|
When you get this message, plug the USB cord back into the
intel Edison.
(If you happen to get an error stop the flashall.sh ctrl+c
and run it again)
It will start installing Ubilinux
Once it's done leave it plugged in and alone for at least 2
minutes…
Connect to it using picocom
There are two ways to connect to the Intel Edison with
Ubilinux (when it is first installed… I will fix it to a simpler way later
on).
1. You can use Ethernet over USB and ssh to IP address
192.168.2.15.
I found this to be a
real pain to get working with the Win-7 + Cygwin combo.
2. The other method is to connect to it via serial
console. To do that you need to
download some software on Cygwin. (As a
side note, the linux 'screen' command should be able to do it, but I could not
get it to work correctly in cygwin.
Instead I am using picocom)
Download and set up picocom
Picocom can be found at https://code.google.com/p/picocom/downloads/list
[7]
Switch to your home directory and download piccom
directly. Untar the download.
|
> cd
> wget https://github.com/npat-efault/picocom/archive/2.1.tar.gz
> tar -xvf
2.1.tar.gz
|
Cd into the picocom folder and run make
|
> cd
picocom-2.1
> make
|
See if picocom.exe is there
|
> ls -alh
|
You should now have a file called picocom.exe
Create a folder to put picocom into. And cd into it.
|
> mkdir
/usr/local/picocom
> cd
/usr/local/picocom
> cp
~/picocom-1.7/picocom.exe .
> ls
|
Create a symlink (shortcut) to this program. This will make it easier to use this command
in the future.
|
> ln -s
/usr/local/picocom/picocom.exe /usr/bin/picocom
|
To test if the symlink is working you can use the which
command.
|
> which
picocom
|
Perfect it gives back the location of the symlink.
You should now be able to run picocom from any directory
Use Picocom
Plug the USB cord into the console port on the Sparkfun Base
Block.
Cygwin lists USB connection points in the /dev folder. Run
this command to find the connection point.
|
> ls -alh
/dev/tt*
|
If you don't see it you may need to give it a minute to
mount. Just run it again… You may even need to unplug the USB and plug
it in again.
There it is. In my
case its /dev/ttyS17, yours may have a different number.
Use this number to login to the Edison. (Change ttyS17 to what your usb connection
point)
|
> picocom -b
115200 /dev/ttyS17
|
Terminal starts up.
Press the return button!
If you don't you will be staring at a screen doing nothing for a long …
long time!
Hey look the login!
Login with the following credentials.
Username : root
Password: edison
I am in J
There is the Edison command line prompt!
Getting out of Picocom
Before I get too far…. How do you get out of picocom?
The typical ctrl+c will not work.
Run exit to get back to the login screen.
|
> exit
|
Then to get out press Ctrl+a+x (all at same time)
Connect to your Wifi Network
You don't really want to be using picocom to login to
Ubilinux. It is much simpler to loging
via ssh (Secure Shell). The first step
to be able to do this is the connect the Edison to your WiFi network.
Log back into the console using picocom
|
> picocom -b
115200 /dev/ttyS17
|
There is a file located at /etc/network/interfaces. This file defines how to set up your
network. The default settings have the
Wi-Fi turned off, you need to turn it back on and give it the password to your network.
I am going to use a tool called nano to edit the text
file. I typically use vi, which I highly
recommend, but if you are a beginner vi is a hard place to start.
Run this command to open the file in the nano editor.
|
> nano
/etc/network/interfaces
|
To move from line to line use the arrow keys also you will
notice on the bottom a list of commands. ^ means control. Control+X will exit (close the file)
Go to this line "Auto usb0"
Use your arrow keys to move around and add a '#' in front of
auto usb0 (this comments it out, effectively turning the Ethernet over USB off)
Go to the #auto wlan0
Next scroll down to this line and remove the # from in front
of it. (effectively turning on the WiFi
connection)
Assuming you're using WPA for your WiFi, which is typical,
scroll down to this section For WPA
As an example if your WiFi was called rebelbase1 with a
password of downwithvader this is how you would fill this section out.
Update the wpa-psk to the password of the Wi-Fi network.
We are using dhcp (Dynamic Host Configuration Protocol) Basically that means when we connect to the
WiFi we don't care what IP address it gives us, just give us one. There are ways to edit this file so that you
get a static IP address so you always get the same IP address when you connect. But typically on a small home network when
you reconnect you get back the same IP address you had before the router
"remembers" you and gives you the same IP address each time (if it
can).
Save and close the file
To do this you need to first press
Control+x
Then press y
Then press enter
Restart the networking service
Now you need to restart the network on the Edison. To do this run the following commands
|
> service
networking stop
> service
networking start
|
Hopefully you are now connected and you now have an IP
address from your WiFi network.
To check what your IP address is run the following command.
|
> ifconfig -a
| grep wlan0 -A 1
|
In the wlan0 section look for inet addr. I have IP address 192.168.0.9. Take note of your IP address.
Test Your Connection out!
From the edison see if you can ping google.com
|
> ping
www.google.com
|
It's working press ctrl+c to stop
|
> ping 192.168.0.9
|
Login via SSH
Exit out of the serial console.
|
> exit
|
Then press ctr+a+x to exit
out of picocom
Now, hopefully you never have to use picocom again J
Now it does not matter which USB port you are connected to
as now you just need power. Also if you
have another power source… like Sparkfun battery module you could use that and
not even have it plugged in via USB.
Point being… at this point your Edison does not need to be
tethered to a computer at all.
Login via ssh! (Use
your IP address)
|
> ssh root@192.168.0.9
|
When prompted to continue enter (yes). Then when prompted for you password enter
'edison'
You are now logged in!
Exit it
|
> exit
|
(no more need for ctrl+a+x)
That's it! You are done!
You have Ubilinux installed and you have the Edison connected to your WiFi
network which allows you to easily SSH into your Ubilinux Edison Server
