From your description it sounds like you can build the code and deploy it. It sounds like the code is running into some sort of run-time exception (probably a memory fault) and exiting which is why it says "no robot code".

The easiest way to figure out your problem is going to be to enable the NetConsole. You will be able to watch the OS boot up and you will see something printed to the console if your code is indeed crashing. To solve the crash you probably want to comment out everything and get to a point where the code runs. Then starting adding things back one at a time until you find the issue. Also add a bunch of print statements so you can trace the execution of the code. Good luck!
