Pixhawk 6c mini

Is anyone had drama with pixhawk 6c mini FC, i had problems with the firmware. I used latest 4.4.0 firmware but the gimbal camera and Neopixel led won’t work, I’m using same frame and board for pixhawk 4 mini using firmware 4.2.2 and works perfectly both camera gimbal and neopixel led. I’ll try to downgrade the pixhawk 6c mini firmware to 4.2.3 and gimbal works but the neopixel led still not working. And another thing when I updated the firmware of pixhawk 4mini to latest 4.4.0 and lost the camera gimbal and neopixel led same setup and don’t have choice of downgrade to 4.2.2 firmware and works perfectly. Appreciate any help

Thanks a lot
