This discussion comes from Roland Mayer’s post here in the Copter-3.6-rc3/-rc4 thread.
With ChibiOS relay not working on AUX in combination with Oneshot125 or Dshot on Aux. With Nuttx Relay funktion is ok on Aux in combination with Oneshot125
We think this is probably related to the BRD_PWM_COUNT being incorrectly set. Can you provide a log and/or parameter list?
high vibration on IMU2 (IMU1 and IMU3 look OK)
the IMUs run at different rates so it is possible they will see different vibration levels. To be sure it is not a bug in ChibiOS can you repeat a flight with NuttX?
When RC speed set 50 there is no Oneshot at Aux Port - ESC detected PWM. if I set Servo Rate to 50 Oneshot still available. its not so logic for my understanding because I thought RC_speed ist for IO-out and the new Servo Rate for Aux.
With Dshot motors sound strange, no smooth running like with oneshot125.
I have to revise Dshot Kiss esc behaviour - probably it was related to the RC speed setting was 400
I’ll pass on these DShot items to @tridge who will probably have a better idea of what to check.
