Facing issue in Controlling Aux1 through RC

PX4 Autopilot Multicopter 🛸
1

I have cube orange flight controller with PX4 1.13.0.
I have set the parameter PWM_AUX_MAX1 to 2000, PWM_AUX_MIN1 to 1000, RC_MAP_AUX1 to 6

while toggling RC channel 6 not change in AUX output.
Trying to control servo motor

Is the vehicle armed or pre-armed? To set it to pre-armed mode (servos enabled but not the motors) without having to press the safety switch, set COM_PREARM_MODE to “always”.
