TDA4VM: Is there any GPIO placed on the eval board that we are able to configure?

Hi TI,

is there any GPIO accessible on the eval board as a gold pin, that we are able to configure by means of software running on Linux OS?

Regards,

Peter

    Hi all,

    Most of the SoC pads have GPIO as one of the mux function.

    You can find any gold pin on the EVAL board, find the corresponding SOC pad and set the pinmux function for it in the GPIO mode

    You will start using this as GPIO which can be driven from Linux.

    Hi Piotr,

    Nikhil's response is correct, but to be more specific and give you on starting point. Please refer to the answer below.

    Since you clarified offline that you are also interested in checking this from RTOS, please refer and run the GPIO example application that is part of the RTOS SDK package. With this you will be able to toggle the GPIO (WKUP_GPIO_6), and then be able to see this change on the gold pin TP45 on the common processor board.

    Regards
