GettingTheGCSRunningonAGumstixBoard

Intro

Please take note that the page is in work at the moment and that I am doing my best to have it updated as soon as possible.

Would it not be great to have your small UAS in your backpack, throw it in the air and monitor and even adjust the flight via a small device in your pocket? If you think this would be awesome, read on, since that is what this page is all about. It is the first attempt and will not be about iPad, Android Phones, Amazon Kindles or the likes as a ground station. For this we have other wiki pages. No, we will use a thrusted solution; A Gumstix with Linux on it.

Outcome

Have the Paparazzi GCS monitoring and adjusting a UA via an small Gumstix based device.

Hardware

What do you need to get this working:

1. A gumstix board with a charger
2. 8 GB SD card
3. USB to mini-USB cable
4. UTP network cable
5. Camera
6. 3.5" screen (such as the LCD panel with the Chestnut) or 4.3"

Software

Needed softwares to run this application:

1. Paparazzi software
2. Ubuntu kernel on your Gumstix
3. Driver for the camera in order to be used with the Gumstix

Well, we have some tutorials on this wiki about how to install Paparazzi. Please have a look and you will definetly find all you need to know.

Before proceeding

You may get some errors during this installation. This depends on how well you are cooling down your system, how much RAM you have on your platform, the OS you are using and so on. Here are some of the errors I occured and how I solved them. You may need to worry about them or not.

If you get errors when trying install a big number of packages/libraries at once, try to divide them in smaller groups.

1. Add swap file

Due to lack of RAM memory it is possible to see errors like this:

==== ERROR [while installing ocamlfind.1.3.3] ====
Internal error:
  # opam-version    1.0.1 (1.0.0-84-g9b3ff34)
# os              linux
opam: "fork" failed: Cannot allocate memory
'opam install ocamlfind' failed.

The solution to this problem is to create a swap file. For this case I created a 512 MB swap file, but you should adapt it's size to the size of your SD card and the needed memory size. Run this commands as sudo:

dd if=/dev/zero of=/swapfile1 bs=1024 count=524288 (will create 512 MB swap file)
mkswap /swapfile1
chown root:root /swapfile1
chmod 0600 /swapfile1
swapon /swapfile1

This will remove the swap file each time you shutdown. If you need the file, you have to repeat the swapon command after each boot. For more explanations you can go to this website

Because the original image was created as 4 GB big, you have to execute the fallowing set of instructions to enlarge it:

1. Add more space

  39  mkfs.ext3 /dev/mmcblk0p3 
  40  vol_id --uuid /dev/mmcblk0p3
  41  blkid /dev/mmcblk0p3 
  42  vim /etc/fstab
  43  mv /home /oldHome
  45  mkdir /home
  46  mount /home
  47  mount
  48  mv /oldHome/* /home/
  49  rmdir /oldHome/

Create an OS

Pre-requisites

1. 8 GB SD card or larger
2. Download the pre-built image from [vexpress-ics-gcc47-armlt-staging-alt-open.img.gz]

Installation Steps

1. Unzip the downloaded pre-build image
2. Insert SD card and note the assigned '/dev/sdX'

dmesg
SDCARD=/dev/sdX   (sdcard found from dmesg above)
sudo dd bs=64k if=vexpress-ics-gcc47-armlt-staging-alt-open.img of=$SDCARD     

Once you have the image written on your sd card you can insert it in the Gumstix and boot up. Then type the following in the CuteCom command prompt:

printenv
setenv defaultdisplay lcd43
saveenv
run mmcboot

After this you can reboot your system.

Connecting peripherals

When you have a Linux version running on your Gumstix, you can add a LCD, or a mouse, or a keyboard.

To set up your LCD you must follow these steps:

Connect trough CuteCom to the Gumstix Restart the board and hit a key within 5 seconds:

Hit any key to stop autoboot: 5

Then type the following in the CuteCom command prompt:

setenv defaultdisplay lcd43

Or, if you are using a 3.5" screen (such as the LCD panel with the Palo35):

setenv defaultdisplay lcd35

You can save this setting for future boots by saving it:

saveenv

Finally, continue with the boot process by typing in CuteCom command prompt:

boot

Connect to the Gumstix through the network

If you want to send files to the Gumstix, you can do it via a ssh connection. In order to do this, both devices, your computer and the Gumstix must be connected to the same same network. Once you did this, you can start setting up the connection. Fistly, you need to know the IP address of the Gumstix. Start by opening CuteCom and connect to the device. When the system loaded, type into CuteCom command prompt:

ifconfig -a (if you can't use this command from any reason you can get a list with all the ips on the network \
using 'arp -a')

Among the data returned, you will see something like this:

eth0      
 Link encap:Ethernet  HWaddr 00:15:c9:28:c9:ff  
 inet addr:169.16.29.3

Now enter into the command prompt:

sudo dhclient eth1 169.16.29.3

When this is done, install on the Gumstix openssh write into the command prompt:

sudo apt-get install openssh-server

Set a password:

sudo passwd username
password  (replace password with any string you want as password)
password  (retype the password you chose)

To add the user to the sudoers group do:

sudo adduser username sudo

Now you should be able to connect using:

ssh root@169.16.29.3

Remove the login prompt

You may want to set your OS to auto-login. Why? Because you may not have at any time a keyboard for the Gumstix around. It is explained here very well how to do it. You have to write in your command prompt:

sudo vi /etc/lightdm/lightdm.conf

and then modify the lines as indicated on the webpage above.

There is a chance to get an error like this "Gtk-WARNING **: Locale not supported by C library.". To solve this write into your command prompt:

sudo update-locale en_US.UTF-8
sudo export LC_ALL=en_US.UTF-8

or the right locale for your keyboard. If this didn't solve your problem, you may want to read here more about it.

Remove the Lightdm GUI for freeing memory

sudo apt-get remove lightdm

After this step you must reboot.
