Motor twitching after arming - DSHOT/BLHeli issue?

After upgrading to the latest (dev) version, I found that apparently some changes have been made to BLHeli/DSHOT-related parameters, for example SERVO_DSHOT_ESC seems to be a new addition.

I tried my best to set them up but after arming the motor is twitching randomly. I tried several types of DSHOT but the issue remains. ESC telemetry is working and the motor reacts to throttle input, but with the twitching at zero throttle I obviously don’t want to risk flying.

Here are the parameters:

SERVO_BLH_3DMASK,0
SERVO_BLH_AUTO,1
SERVO_BLH_DEBUG,1
SERVO_BLH_MASK,1
SERVO_BLH_OTYPE,4
SERVO_BLH_POLES,14
SERVO_BLH_PORT,0
SERVO_BLH_RVMASK,0
SERVO_BLH_TEST,0
SERVO_BLH_TMOUT,5
SERVO_BLH_TRATE,10
SERVO_DSHOT_ESC,1
SERVO_DSHOT_RATE,1

I could also make changes to the ESC settings using BLH passthrough and BLHeli32Suite, but at this point I wouldn’t know what to try. The ESC (Holybro Tekko32) is new and at default settings.

Thanks for any hints.
