OK I'll stick to main BOARD.Pulled a board out, unplugged the IMU, and got the same thing. Four white blinking, one solid beside the red (red off). Could be something other than the IMU on your board, but your board is not initializing correctly.
Do you still have your old Chroma Main Board? And its IMU module?
By the way, "FC board" usually refers to the controlling board inside the ST10+. I'm pretty sure we are both talking about the Mainboard inside the Chroma, but wanted to make sure.
This the old BOARD I'm using for this, it's IMU is in the Chroma, no IMU on this board.
Will have to dismantle Chroma to do this.
Did this procedure make a sick BOARD well again?
I will take a little more time than you to get the IMU + BOARD out of the bird.
Maybe this is the root cause of all this, same IMU for both !
Proceed yes or no??
