    babs76
    Hello, I'm trying to use DMAN3 and ACPY3 to perform DMA transfers in the DSP. I've followed the VIDENC_COPY example but my code hangs when ACPY3_activate is called. With CE_DEBUG=3, I also noticed I did not see any output from the DMAN3_init() or ACPY3_init(). Just to verify I had debugging...

    FYI, I've moved this post into the BIOS forum as that's the SW environment a Server runs in. Can you provide which version of Codec Engine you're using? Also, the search path you're providing to GenServer ? Chris

  • Forum Post: Re: Debugging XDAIS alg via CE on DSP simulator

    Chris Ring
    Most of the CE example apps support building in 'local' mode, where the app is on the same processor as the alg. Look for the 'local.cfg' config scripts. If you're using a semi-recent version of CE, you might be able to simply ensure (in examples/xdcpaths.mak) the PROGRAMS var...

  • Forum Post: Re: Cannot run the Genserver Wizard in CCS4.2.3

    Chris Ring
    GenServer is not supported in that release of Codec Engine. Bummer that you don't get a better error msg. CE 3.20.* only supports BIOS 6 (no Linux), and only 1) local codecs or 2) remote codecs on homogenous multicore processors (like C6472 ). In the local codec case, there isn't a Server...

  • Forum Post: Re: Cannot run the Genserver Wizard in CCS4.2.3

    Chris Ring
    You should use the version of CE included in the SDK - something in the 3.21.* family. CE 3.21 is not yet GA (Generally Available - implying production quality), meaning it's still under development. But pre-releases for new devices (like C6A8168) have been made available via the EZSDK releases...

This will help DSP get all the QDMA channels except 7,...
