We are using Jetson Tx2 in our project. We need to check the status of the GPIO11_AP_WAKE_BT (B19) GPIO pin. By referring to Google and previous forum references, we understood that we need to find the GPIO number and then we can export the same and use the pin.
We referred the Jetson TX2 pin mux template and found GPIO3_PI.05 as the GPIO pin mux. We have calculated the GPIO number as 320 + ((8*8)+5) = 389.
We have exported the same in sys/class/gpio/ but we are unable to read the GPIO status.
Please help me for reading B19 GPIO status.
