I have powered up the drone (4amp 12V) and while the ESC lights are flashing, the fan is spinning up and the RGB light is green, but there is no output from the HDMI. https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-setup The instructions suggest that there should be yocto installed or I should a at least a bios screen. Do you have any suggestions for debugging this?
Thank you for your interest in our Intel Aero drone.
Do you require any more assistance with this issue?
