Thanks for the logs and backup file. I do not see any issue with MyController restored in my local(I tested with SNAPSHOT version).
From your log file, I see that MyController takes a lot of time to start[57, 62, 67, 1807 seconds]. seems like your raspberry PI loaded with some other application?
If yes, I request to stop all other application running in your raspberry PI and try again.
I recommend using RASPBIAN OS LITE edition.
