Getting Started

You need download the operating system and install it in one SD Card. Here the different ways depending to your OS.

Check which disks are mounted in you computer:

$ df -h
S.ficheros     Tamaño Usados  Disp Uso% Montado en
/dev/sda1         26G    21G  3,7G  86% /
none             4,0K      0  4,0K   0% /sys/fs/cgroup
udev             2,0G   4,0K  2,0G   1% /dev
tmpfs            404M   960K  403M   1% /run
none             5,0M      0  5,0M   0% /run/lock
none             2,0G   220K  2,0G   1% /run/shm
none             100M    52K  100M   1% /run/user
Home             112G   103G  9,2G  92% /media/home/

Insert the SD and run again df -h, check how the new disk is named :

$ df -h
S.ficheros     Tamaño Usados  Disp Uso% Montado en
/dev/sda1         26G    21G  3,7G  86% /
none             4,0K      0  4,0K   0% /sys/fs/cgroup
udev             2,0G   4,0K  2,0G   1% /dev
tmpfs            404M   960K  403M   1% /run
none             5,0M      0  5,0M   0% /run/lock
none             2,0G   220K  2,0G   1% /run/shm
none             100M    52K  100M   1% /run/user
Home             112G   103G  9,2G  92% /media/home/
/dev/sdb1         56M    20M   37M  36% /media/inigo/boot
/dev/sdb2        3,8G   2,8G  759M  80% /media/inigo/13d368bf-6dbf-4751-8ba1-88bed06bef77

Notice that the new disk is named sdb and has two partitions sdb1 and sdb2

Now umount the SD:

umount the disk:
umount /dev/sdb1
umount /dev/sdb2

Now, flash the image in the SD:

# if you have uncompressed image:
sudo dd bs=8M if=/path/to/image/erle_image_name.img of=/dev/sdb

#if you have img.gz compressed image:
sudo zcat /path/to/image/erle_image_name.img.gz | sudo dd of=/dev/sdb bs=8M

#if you have tar.xz compressed image:
sudo xz -dkc /path/to/image/erle_image.tar.xz > /dev/sdb

Check which disks are mounted in you computer:

$ df -h
Filesystem      Size   Used  Avail Capacity  iused   ifree %iused  Mounted on
/dev/disk1     112Gi  102Gi  9.1Gi    92% 26932856 2393446   92%   /
devfs          186Ki  186Ki    0Bi   100%      643       0  100%   /dev
map -hosts       0Bi    0Bi    0Bi   100%        0       0  100%   /net
map auto_home    0Bi    0Bi    0Bi   100%        0       0  100%   /home

Insert the SD and run again df -h, check how the new disk is named:

df -h
Filesystem      Size   Used  Avail Capacity  iused   ifree %iused  Mounted on
/dev/disk1     112Gi  102Gi  9.6Gi    92% 26803002 2523300   91%   /
devfs          187Ki  187Ki    0Bi   100%      647       0  100%   /dev
map -hosts       0Bi    0Bi    0Bi   100%        0       0  100%   /net
map auto_home    0Bi    0Bi    0Bi   100%        0       0  100%   /home
/dev/disk2s1    56Mi   20Mi   36Mi    36%      512       0  100%   /Volumes/boot

Notice that the new disk is named disk2 and has a partition disk2s1

Now umount the SD:

umount the disk:
diskutil unmountDisk /dev/disk2

Now flash the image in the SD:

#Flash uncompressed image
sudo dd if=/path/to/image/erle_image.img of=/dev/rdisk2 bs=8m conv=sync,notrunc,noerror

#Flash compressed image
gunzip -c /path/to/image/erle_image.gz | sudo dd of=/dev/rdisk2 bs=8m   

First of all, download Win32DiskImager and unzip it.

Execute Win32DiskImager utility, run it as administrator (right click adn select "Run as Administrator").

Decompresses the image (with Winrar or other program) and verify that your SD Card contains enough space to house the OS.

Select the image you want to flash.



Select the drive letter of the SD card in the device box.

Be careful to select the correct drive; if you get the wrong one you can destroy your data on the computer's hard disk!

If you are using an SD Card slot in your computer (if you have one) and can't see the drive in the Win32DiskImager window, try using a cheap Adapter in a USB slot.

Click Write and wait for the write to complete. Exit the imager and eject the SD card.

Plug into the microSD slot the freshly flashed image.

Now that you have your Erle-Brain 3 with an Operating System you can start exploring it. First of all connect your Erle-Brain3 to the internet using the ethernet and start downloading the containers. Read more about our Modular Debian OS solution here.

Once your brain is configured and the operating system is running, the next step is to install a flight stack or in other words, an autopilot. Erle Robotics offers support for two software autopilots solutions:

NOTE: This step is required if you are using "frambuesa" OS.

After choose your robot/drone, you need connect the necessary components for your vehicle (WiFi, RC receiver, GPS...). You can find more info about this at Robots section.

All necessary software for these hardware are included. You can find more info about the hardware at hardware section.

The correct way to shutdown your Erle-Brain 3 is typing in your terminal the following command:

sudo shutdown -h now
