i'm mounting a new drone with a3 (no rtk) board.
When i power it after initializing go to diagnostic mode (led blink in all colors) and still remain in this state (also after 1 hour).
In assistant also report that imu is in diagnostic mode and suggest to wait.
But in assistant i don't see gps module (connected) and gps led is white
Led on Flight controller blink green and it, after few minutes, become very hot.
I attach screenshot of assistant program and this is a video of all system and led
In assistant all seems blocked, i cannot change parameters and if i try to reinstall firmware when i press "start" board go in disconnected status from pc
