I am currently using an Overo Fire COM with a Caspa Camera. As I am new to this device, I met a problem after creating a bootable MircroSD card using GNOME Daily builds (r13) which is recommended for beginner. When I insert the card into the Overo slot, power on and configure it using serial connection. I could not get a display image on the display screen. Can anyone provide some guidance and help for me as I do not know what is the problem.
