I have a small P5 matrix (2x2) using a BBB as a controller. This worked for a day or two but then the display didn't come on anymore. I have it on a timer and I see the controller coming on but the display on the Octoscroller shows "idle". There is a test button on the BBB and when I press it the lights are coming on so I know the matrixes are working. I did use Tool->FPP Connect to upload my sequence and based on the LEDs I believe it did update it. How can I get my sequence to start automatically and keep repeating with the BBB?
