Hi and welcome to devnet,
That's not enough details.
What are you building ?
How are you building it ?
Which tools are you using ?
What does trigger that rsync ? -
Hello SGaist,
Building: the famous "Hello" programm
How/Tools:: QT Creator, last Version downloaded and installed with atp... QT5 integrated in buildroot, Connection over SSH with the board, (configured in Creator -> devices), Creator sends files after compiling/building to the board and generates the error messages. (lower part of Creators projekt screen "issues")
rsync: triggered by Creator
Sorry for the missing informations
Marc
