I can see the cockpit and camera and can successfully upload the arduino firmware and I can program my ESC with a program card. The control board has a power light.
The cockpit reports 0V, will not respond to keyboard commands, and I cannot calibrate the ESC. Example when I try calibration the motor does not drive and the ESC does not double beep. I have no telemetry from IMU
Calibration: I get continuous beeping then hit the reset and get one beep then move slider to 1 and hit reset (no beep no motor).
I have 2.7 board, factory assembled db25, old style black ESC and IMU. I disconnected the home plug from the controller board as an attempt to buypass. I am still using the tether USB plug to power on and off, I have not jumpered anything on the control board.
