Other Parts Discussed in Thread: AM5K2E04, OMAP-L138

Hii

i am having the two different board one is OMPAL138 2nd one is AM5K2E04 , I want to interface between both the board for HPI protocol but Our AMK52E04 board do not have any HPI ,so I am planning to use the GPIO( Using Bit bang method) for communication between same, I want to know that using Bit Baging method it is possible to communicate or not If possible then please let me know the working and configuration procedure.

Thanks in Advance

    Hi, Hil,

    We have not tried this and don't have info on it. Nor do we have the configuration for it.

    Hello Rex

    Thanks for your reply

    As you said you have not tried nor configure then is there any other method to interface between OMAP-L138(HPI side) & AM5K2E04 Board.

    If you provide any information regarding this it will be very much helpful.

    Thanks in Advance

    Hi, Shubham,

    What is the application that you need to interface OMAP-L138 with AMK2E?

    Hi, Rex

    Thanks for your response

    Actually we are working on two different board

    1.OMAP-L138 & 2.AM5K2E04

    On OMAP-L138 side we are using BARE METAL Source code

    On AM5K2E04 side we are using LINUX BSP Source code(Yocto PSDK)

    Now OMAP-L138 side has HPI port and AM5K2E04 has GPIO's for which we are planing to using BIT BANG method.

    My Query is Is it possible to communicate between OMAP-L138 (HPI Port) and AM5K2E04 (GPIO's Port) ? If yes then can you please provide some information about it?

    Thanks in Advance

    Hi, Shubham,

    I am just curious what application will need to use this way of communication than using other interfaces with higher speed. I assume you are sending data between the two devices. GPIO will  have high latency than other interfaces. We design the GPIO for raising events, not for communicating data. You may use it if just for prove of concept, but not where it is designed for.
