Use on a cb20 Board
The following is a step-by-step procedure to get started using EEROS on the 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.
Prerequisites
- Get an suitable image for your cb20 platform from Linux Images and install it on your target system, see https://wiki.bu.ost.ch/infoportal/software/linux/toradex/toradex-easy-installer.
- On the host, you have to fetch the cross development SDK for the cb20 board from Downloads and install it on the host according to Installing the SDK. Unpack it on your host system with
$ tar -vxJf ntb-dev-image-cb20-1.0_sdk.tar.xz
Change into the sdk directory and execute the script therein with
$ cd sdk $ ./tdx-xwayland-glibc-x86_64-ntb-ros-image-melodic-armv7at2hf-neon-cb20-toolchain-5.0.0.sh
Fetch the EEROS scripts on your cross development system with
$ git clone https://github.com/eeros-project/eeros-build-scripts.git cb20 $ cd cb20
Edit the file config.sh.in
as follows
use_simulator=false use_flink=true use_bbblue=false use_comedi=false use_ros=false use_can=false use_custom_application=true use_cross_compilation_environment=true use_ros_setup_script=false
The entry use_cross_compilation_environment
ensures that you compile using an SDK built for the target platform. Make sure to install the SDK by
- downloading the SDK from Linux Images
- installing the SDK as described in https://wiki.bu.ost.ch/infoportal/software/linux/toradex/toradex-sdk
Edit the file config.sh.in
as follows
environment_setup_script=/opt/tdx-xwayland/5.0.0/environment-setup-armv7at2hf-neon-tdx-linux-gnueabi
This will guide your make script to use the SDK. Make sure that the above path matches your installation path.
If you want to use CAN, choose
use_can=true
Setting the entry use_custom_application
to true will fetch an existing application from a git repository. Per default this will will be https://github.com/eeros-project/simple-motor-control.git. However, you could choose another repository in config.sh.in
. Or you could set the entry to false if you want to develop your own application.
Now you can run the clone
script
$ ./clone.sh
After this you can continue with Compile.
