I built a quadcopter with KISS ESC and I want to use it with Cube Black FC. I followed this tutorial for setup ESC with DSHOT: https://ardupilot.org/copter/docs/common-dshot.html
However, when connecting ESC to AUX Ports of Cube Black, the Cube didn’t boot completely most of the time and Ardupilot didn’t start at all!!! Specifically, the orange LED of the Cube Black flashed continuously, and then when I connected the USB cable it mounted a different COM Port (COM8) instead of COM9 (when it boots normally).
Additionally, the Cube will boot normally all the time when I remove ESC connections to AUX Port or when I connect it to Main Port to use PWM. I tried two Cube Black and two ESC units but I still have the same issue.
Could anyone give me some suggestions or show me how to find the error during booting of the Cube? I would very much appreciate any help/comment!
