EDMA3 is not working properly with codec engine2.10.02

This link has some information on common issues leading to hangs, when using ACPY3.

http://processors.wiki.ti.com/index.php/Framework_Components_FAQ#ACPY3_Questions

Thank you for your prompt response gunjan,

I m copying DDR to DDR. both the buffers in external memory. i am not hanging on ACPY3_wait function.

The process hangs immediately after a single transfer is apparently completed (we don’t get a chance to see if it got transferred correctly or not). We have put breakpoints in the code using CCS and a JTAG emulator.  We have two such transfers lined up sequentially. The code hits the breakpoints before the ACPY3 params are configured and after the  transfer is completed for the 1^st one but doesn’t even hit the breakpoint to begin the next transfer.

here is my configuration

var DMAN3 = xdc.useModule('ti.sdo.fc.dman3.DMAN3');

DMAN3.heapInternal = "IRAM";

DMAN3.heapExternal = "DDRALGHEAP";

Hello Gunjan,

I am eagerly waiting for your response on this issue.

It is highly appreciated if you could revert back ASAP.

Naresh

Hi Naresh,

Inside your algorithm can you check the and see if the 'env' field of the IDMA3_Handle that you are passing to the ACPY3 functions is an internal memory address?
The 'env' should be allocated in internal memory, and you could get stuck if it has been allocated in external memory due to some configuration issue or running out of internal heap.

Best regards,

Murat

Thank you Murat for your response.

I am new to this DSP DM6467. Can you please guide me how to check t 'env' field of the IDMA3_handle is in internal memory and how to configure it.

here is the .cfg file content of combo module.

Naresh

Via a breakpoint in your algorithm, at the point where you call ACPY3_configure (or any other ACPY3 function) look at the fields of the IDMA3_Handle you are passing to the ACPY3 function. The 'env' field is a pointer containing the address of the memory allocated for the handle's env structure, this address must be an internal memory address. So, you should check and make sure this is the case.

Thanks Marut for your early response.

I test the code as per your guidance and check the memory address of 'env' field .

Please look the below code. THere I mentioned the location of break point.

Void VCA_ALGORITHMS_MT_doCopy2D2D(IDMA3_Handle dmaHandle, Void *in, Void *out, ElemStruct *elem)
{ // first break point
 
    ACPY3_Params params;
    /*
     * Activate Channel  scratch DMA channels.
     */
    ACPY3_activate(dmaHandle);
 
 /* Configure the logical channel */
    params.transferType = ACPY3_2D2D;

 params.srcAddr = (void *)in;
    params.dstAddr = (void *)out;

    params.elementSize =(elem->LineLength);
    params.numElements =(elem->NumLines);
    params.numFrames = 1;

    params.srcElementIndex = elem->srcLineOffset;
    params.dstElementIndex = elem->dstLineOffset;

 params.srcFrameIndex = 0;
    params.dstFrameIndex = 0; 

    params.waitId = 0;

  /* Configure logical dma channel */
    ACPY3_configure(dmaHandle, &params, 0);
   
    /* Use DMA to fcpy input buffer into working buffer */
    ACPY3_start(dmaHandle);

    /* Check that dma transfer has completed before finishing "processing" */

//secound break point
    while (!ACPY3_complete(dmaHandle)) {
        ;
    };

    /*
     * DeActivate Channel  scratch DMA channels.
     */
    ACPY3_deactivate(dmaHandle);

}// third break point

Memory address of 'env' field

at Break point 1
memory address of env: 0x8c131cc0 (external memory)
memory address of dmahandle[0]->env: can't load from non primitive location

at Break point 2
memory address of env: 0x118118020 (internal memory)
memory address of dmahandle[0]->env: can not load from non primitive location

at Break point 3
memory address of env: ox8c131cc0 (external memory)
memory address of dmahandle[0]->env: can not load from non primitive location

Now how can i decided the actual memory addres of env field? IS it internal or external?

Can you please guide me in this regard?

thanks

Hi Naresh,

Once the channel is activated via ACPY3_activate the 'env' field is assigned an internal memory address, so that doesn't seem to be a problem. I am not sure what the issue is at this point. Are you still stuck with the problem?

Hi MArut,

Yes, I am still stuck with the problem.

Please do needful ASAP

regards,

NAresh 

Can you please show exactly which lines of code get stuck?  Perhaps copy/paste your code and highlight put a comment somewhere like "never gets here".  I apologize if you already gave that info.  I've been hunting through your code but couldn't find it.  Does it always get stuck at the same place?  Just so I understand correctly, you never hit your breakpoint at all correct, as opposed to hitting the breakpoint but the data not copying correctly?

Hi

Here is the code. I highlited the breakpoint with yellow colour.

After few frames code get stuck at the same place every time.(number of frame is not consistent ). code get stuck so we can not verify the data, its correct or wrong.

I don't see anything that jumps out with your EDMA code.  Based on the fact that it fails after a random number of frames I suspect something like a stack overflow, etc.  You should go through some of the steps listed here:

Hello Brad,

As per your guidence, I check the stacks in the CCS. but there is no any stack obverflow occured.

Still stuck with the same problem.

plz guide me furthere.

regards,
