You have too many parameters configured. Set these:
BRD_IO_DSHOT,0 (won’t effect anything but you are not using the main outputs for Dshot so disable it)
SERVO_BLH_MASK,0
SERVO_BLH_OTYPE,0
The last 2 may be more bullshit from the Rosser guide.
Then confirm with messages that RCout 9-14 are Dshot.
This is misconfigured as I posted. If you want to fool around with V4.6 go ahead. If you want to find out what the problem really is then update to V4.7 and make the changes I suggested and work thru it. If it’s configure properly and you still have trouble with getting all 6 outputs to work with Bdshot then we have to look further.
