BBBlue "sudo make runonboot" ERROR

I have a program that runs fine from the command line of my PC when connected via WiFi to my BBBlue Diff-Drive robot. I can use the Pause button on the board to start and stop the robot (code is from the wonderful Project Template), but now I would like to run it without using the PC. However, when following the instructions on the Robot Control Library website for making my robot run on boot, I am getting an error about the PWM Driver timing out. Any advice would be greatly appreciated. Here's the screenshot of the error:

Start by reproducing `sudo make runonboot` on the BBBlue while following the Robot Control Library website instructions, then inspect the attached PWM Driver timeout screenshot and the Project Template setup. Done means identifying the boot-time cause of the timeout and documenting or correcting the setup so the robot runs without the PC.
