Regarding information of McBSP port of Tms320c6713 Dsk Eval Board.

Dear Friend,

I am presently work on Tms320c6713 Dsk Eval Board. I have already used GPIO  and EMIF port for external data communication. Now i also need to used McBSP port with GPIO  and EMIF port for the same program for high speed data communication.  But i have seen that working with GPIO  and EMIF port altogether, program is working successfuly, but when i add McBSP program code with related library, it is not working. But independetly, McBSP port with it's library file,  is working correctly.

Kindly help me to know, these three communication port is not worked all together ?

If not, how i use McBSP port with EMIF & GPIO.

Wait for your kind help..

Regards

Gopal

  • Hi,

    We are working on it and will get back to you shortly.

  • Hi Gopal,

    Go to Product Folder, click on Technical Documents to get the EMIF User's Guide for your device. It will explain how the EMIF works and what the registers are that need to be configured. Once you have it configured correctly, all you code has to do is set a pointer to the address you want to read or write and access it as you would any memory location.

    Also , At the bottom you will also find a link for list of Application Notes for TMS320C67x DSP. Read through some of these to get an idea of what other people have done to interface to their devices.

    I have not cleared from your reply. My problem is not absolitly on EMIF interface issue. External interfacing using EMIF & GPIO port are
    successfully done. But my problem is about McBSP interface when i want to use it with EMIF & GPIo port all together.
    Individually McBSP interface is working and i have checked it.
    wait for your kind response.

  • Gopal,

    Yes, you can use these interfaces together. Something in your code or hardware is causing your problem.

    The simplest place to look is for pin conflicts. Are you using pins for GPIO that are also needed by the EMIF or McBSP?

    After eliminating hardware issues, you will need to find what in your code is causing the problem. Figure out your best way to add the McBSP code in line-by-line and test the EMIF & GPIO after each line is added in.
