    Hi Prial,

    Could you please let us know if the HLOS is Linux or you are trying to use RTOS? This will help route your query to the right expert.

    Best regards,

    Hello Prial,

    Before we continue the discussion, please note that there is a difference between the PRU GPI / PRU GPO pin signals, and the GPIO pin signals. You will get the lowest latency, 100% deterministic reads and writes with the PRU GPI / PRU GPO signals. The GPIO signals will have the same latency and nondeterministic latency that you would expect from any other processor controlling a GPIO signal.

    TI does not produce or support the pocket beagle board, so you will need to get the pinout information, etc from the beagle community.

    We do offer a pinmux tool in the SysConfig tool that may be helpful: https://dev.ti.com/sysconfig (or https://www.ti.com/tool/SYSCONFIG for the offline version).

    Regards,

    Nick
