Hello! This is my first post here.
I have recently started using the Navio2 instead of Pixhawk.
I use a custom ardupilot firmware (based on copter 4.0) and had no problem using the Robotis (Dynamixel) servos when I ran it on Pixhawk. (I followed the instructions from the official wiki)
I’ve tried building the same firmware for the Navio2 and connected the UART port (TX and ground) to the servo but it’s not working at all. I’ve checked up on AP_RobotisServo.cpp and it seems that it is unable to identify the port (port == nullptr).
I’ve attached the layout of Navio2 and the servo.
I’m new to Navio2 and I thought I could get some help.
