@l05 , when in doubt, you can add a print statement in your app as a sanity check to make sure you are running the correct version of the application. Then check your print statement at run time.

If you are modifying an existing app in voxl-mpa-tools, you just need to use the voxl-cross docker image to

build the source code build the package (deb) deploy the package (either manually pushing and dpkg -i <package.deb> on target) or using a convenience script deploy_to_voxl.sh which is typically present in most voxl projects -- this script will push the deb to voxl2 and install the deb. run your new application on voxl and confirm functionality

If you are adding a new app to voxl-mpa-tools project, you will need to modify the CMakeLists.txt file in the tools folder, it should be self explanatory how to add a simple app. Once you build and deploy, your new app will be installed into /usr/bin on voxl2.

If you have any other questions, let me know.
