GPIO pins 16 and 26

Hi,

Is it possible to use GPIO pins 16 and 26 on Rock Pi 4 as input pins? I know we can select other pins but due to the configuration of our external interface we must use those two pins. We use mraa on Android 9 and we get “invalid pin specified” error when trying to use those pins as input

Pin 16, a GPIO pin, can be used as input pin.
Pin 26, an ADC_IN0 pin, can not be used as input pin.
