I am using the ADRV9364 with the ADRV1CRR-BOB. I am trying to get a GPIO pin that I can use. I have tried looking at using the LED, switches, or push button pins but I can't get them to work. I have tried controlling the LEDs using the sysfs interface sys/class/leds but they never seem to turn on.
I have tried using the gpio sysfs interface and was able to export several GPIO pins but I am not sure how to match up the GPIO # with a pin number.
In the end I just need to get 4 gpios.
