OMAP-L13X Pinmuxing

Hi,

 I was wondering if I multiplex a certain pin as GPIO from linux, is it available to a DSP/BIOS app?

is the inverse also true? I multiplex from DSP/BIOS a pin as GPIO may I use it as GPIO from linux?

    Hi

    I am not sure what you mean by "available". All GPIOs are equally accessible by both DSP and ARM side, so how you want to use them will be completely software driven.

    You might find the following post useful too

    Hi mukul,

     Thanks for taking the time to review my question, What I meant was, If I use a multiplexing scheme in one of the cores for example in the ARM core and set the muxing in linux

    then I would not need to set the multiplexing in the DSP core  and viceversa. By the way the post you refer me to is quite helpfull.
