====== Use on a cb20 Board ======
The following is a step-by-step procedure to get started using EEROS on the [[https://wiki.ntb.ch/infoportal/embedded_systems/imx6/cb#cb20_board|cb20 Board]]. It describes how to set up the SDK. The application is developed on a Linux host machine and can then be deployed to the board.

===== Install Linux Image on cb20  Blue =====

Make sure to have the newest image from our download section [[https://wiki.bu.ost.ch/infoportal/software/linux/images/start|Linux Images]] installed on your [[https://wiki.bu.ost.ch/infoportal/embedded_systems/imx6/cb|cb20]] board, see [[https://wiki.bu.ost.ch/infoportal/software/linux/toradex/toradex-easy-installer|toradex-easy-installer]]. This image already contains the EEROS library together with examples. Further is includes necessary hardware libraries, notably [[http://flink-project.ch|flink]] as well as basic functionalities of ROS. 

Get the image from [[https://wiki.bu.ost.ch/infoportal/software/linux/images/downloads|Downloads]]. 

===== Install SDK on the Host =====
In order to develop your application on the host, you have to install the cross development SDK.
  - Get the cross development SDK for the cb20 board from [[https://wiki.bu.ost.ch/infoportal/software/linux/images/downloads|Downloads]]. 
  - Unpack it on your host system with <code>$ tar -vxJf ntb-dev-image-cb20-1.0_sdk.tar.xz</code> 
  - Change into the sdk directory and execute the script therein with <code>$ cd sdk
$ ./tdx-x11-glibc-x86_64-ntb-dev-image-armv7at2hf-neon-toolchain-2.6.4.sh</code>Stick with the default target directory for the SDK. If you choose a different directory you have later to manually change the associated entry in ''config.sh.in''. 


===== Install Git =====
Install the following package on your machine <code>
$ apt-get install git
</code>
