  • Forum Post: Re: Problem with DMA on Simulator

    Bernie Thompson TI
    Sandeep may have additional feedback as to specifically how to include the ACPY3 library, but I can say that this is a library and not a header file you need, since this is the linker complaining and not the compiler (linker dereferences all objects to their actual files, and it could not find the ACPY3_start...

  • Forum Post: Re: DM648 EVM video driver lockup

    chris2476
    Currently I am wondering if there might be some DMA conflict. Our algorithm processes at 10 fps, while the application captures at 30 fps. So there are 3 FVID_exchange calls between calls to our algorithm. I noticed that the error always first happens on the FVID_exchange call directly after our algorithm...

    chris2476
    So after some serious debugging, I found that our software library was configuring an ACPY before the previous ACPY finished. This collision resulted in the stall in ACPY_wait, and it was also throwing the video driver for a loop. My theory is that the DM6437 and DM6446 both run slower, so on those processors...

  • Forum Post: Strange DM644x DMA QUEPRI behavior with CodecEngine algorithm

    David Kondrad
    Greetings, We have a strange issue with the DMA QUEPRI register being reset to TI defaults (T0: priority 3, T1: priority 7) every time we call the eVRU video display algorithm. The register is being set to the defaults regardless of what has specified for the DMAN3.queuePri array (which works fine...

    Daniel Nadeau
    I am trying to incorporate ACPY3 into my project by following the exmaple of the fastCopy non-algorithm approach. When I call status = DMAN3_createChannels(0, &dmaTab, 1); I always get the error code DMAN3_EOUTOFTCCS. Here is my DMAN3 setup code that is in my .cfg file. var ACPY3 = xdc.useModule...

  • Forum Post: ACPY3_configure not setting up paRAMs

    Daniel Nadeau
    I am working on using the DMA on the dm648 and following the fastcopy non-algorithm example. My code runs without breaking how the transfer never takes place. None of the memory locations in the paRAM index ever change from 0x0. I have followed the fastcopy example exactly except that instead of having...

  • Forum Post: Re: ACPY3_Wait takes long with two video channels on DM648

    ARM3035
    Its TI video driver so I don't know the DMA usage of the video driver. I thought DMAN3 interface makes sure no one touches others resources and it would have complained at the time initialization when granting DMA channels. ~ARM

  • Forum Post: Linked ACPY3 activation (as replacement for 3d)

    RomaMeshok
    I am new with DaVinci and I have add functionality to existing code using ACPY3 library for QDMA transfers. The required transfer is 3d but QDMA does not support such type. So I am trying to create 3d replacement using linked DMA. Unfortunately, ACPY3 documentation I found does not describe the...

  • Forum Post: Efficient Image Translation, x and y

    babs76
    Is there any easy way to perform image translation (or translate a portion of an image) in the DM6467 other than setting up a DMA chain to do this? Can I use the VDCE or an HDVICP? I just started looking into this, but if someone has a quick answer, that would be great!

    Daniel Nadeau
    I am trying to utilize the DMA via the ACPY3 API. I am using DVSDK 1.11, BIOS 5.4, Framework Components 1.20.03, PSP Drivers 1.10.00, xDAIS 6.23, and CCSv4 on a DM648. I have added this code to my main source file: #include <ti/sdo/fc/acpy3/acpy3.h> #include <ti/sdo/fc/dman3/dman3.h> ...
