Configure EDMA for c6713 in CCS V4.2

zhonghai wang

Hi there,

I am working on a project using timer and EDMA with ping-pong buffer structure
for continually collecting samples on DSK6713.

I can configure the HWI in the .tcf for the timer, but I did not find where to
configure the EDMA using CSL as described in 
http://www.ti.com/lit/an/slaa257/slaa257.pdf. 

In my CCS 4.2, when I open the .tcf file, I only have "System,
instrumentation, scheduling, synchronization and Input/output", but I have
no "CSL - Chip support library", which can configure EDMA channels.

I have read a lot of materials on line, but did not find solution.

Please help me out this point,
Thanks a lot,
Zhonghai

    Zhonghai,

    The configuration of CSL as part of DSP/BIOS configuration was removed several years ago.  If you want to have an integrated DSP/BIOS plus CSL configuration as shown in that app note, then you’ll need to keep using the older CCS that came with the DSK6713 board. 

    If you want to start new development for the board using CCS v4, then I can send you some steps that should get you running DSP/BIOS on the board. (If you haven’t already done so.)  But there won’t be any CSL integration. 

    Is it possible for you to move to a more recent board, like a C6748-based board?

    Dear Scott, 

    Thank you very much for your answer (I have spent a lot of time on it).

    I have only the 6713 board and want to configure its EDMA in a ping-pong structure receiver, would you please send me those steps?

    My email is wangzhon@mst.edu.

    Thank you again,

    Zhonghai

    Zhonghai,

    I don’t have any EDMA ping-pong example to send.  It is possible someone else on this BIOS forum may be able to provide something, but I think you’ll have a better chance if you post EDMA questions on one of the device-related forums.  I see a lot of EDMA related questions on this one: http://e2e.ti.com/support/dsp/omap_applications_processors/f/42.aspx

    One other thought… if you only have the board and no software for it, you might look at the available software downloads for the board from Spectrum Digital’s website. There is a “Target Content” link with several examples on this page: http://c6000.spectrumdigital.com/dsk6713/

    Dear Scott,

    Thank you very much. I checked the Spectrum Digital’s website, and did not find useful information.

    I found "Using CSL APIs Without DSP/BIOS ConfigTool" in "TMS320C6000 Chip Support Library API Reference Guide".  but this one is for DMA, is there any example for EDMA for 6713 like this one? 

    Another question: do you have an estimation how long the C6748-based board will last: I mean the whole technique support the board life.

    Can you please further clarify your question? Are you asking for the duration of support for device/continuity of supply, the software for the device, or how long the EVM will last?

    Hi Mukul,

    I do mean the duration of technique support for the device, especially the CCS system.

    In addition, if we want to start with C6748, is there a EVM for it or should we use the OMAP-L138/C6748/AM1808 EVM board?

    Thank you very much,

    Zhonghai

    CCS supports C6713, C6748... this support is still present in the latest CCSv5.1.
