datasheet for the board?
Thanks for responding. It is hard to learn how to present a question, sorry. When I tried I did replace "ARDUINO...DIR" with the correct path to the folder where the sketches are stored. Effectively I moved the working directory to my "ARDUINO...DIR" My problem was in executing the GIT Bash session:git submodule update --init --recursiveI got the error message :"No such file or directory"So I do not know how to successfully do this step!
