  • Hi Socrates,

    I have forwarded your question to VisionSDK expert, he will respond here.

    You can also check the document in this link for description of memory layout in VisionSDK to see if it can give you some direction:

    Hi

    What is A15 side OS, Bios or Linux?

    regards, Shiju

    Hi Shiju,

    Platform : TDA2x
    Package: VSDK 2.10
    A15 side OS: BIOS

    The pdf you have shared is for VSDK2.12. In fact we do not have any plan of migrating to VSDK 2.12.

    Please help

    Thanks

    can you please provide more details on which memory section you have increased and how much?

    regards, Shiju

  • In reply to Shiju Sivasankaran:

    Hi Shiju,

    PFA mem_segment_definition_512mb_bios.xs for your reference.

    We have increased DSP2_DATA_SIZE as  72*MB;

    Thanks

    Hi Socrates,

    Just to confirm when you are building your code do set ECC_FFI_INCLUDE = yes?

    Thanks and Regards,

  • In reply to Piyali Goswami:

    Hi Piyali,

    In our build ECC_FFI_INCLUDE is set to "no"

    Hi,

    When i allocate memory in DSP non cache section, I get this MDMA error. However when I allocate memory in A15 non cache section, I do not get this MDMA error.

    Regards,

    Socrates

  • In reply to Socrates Paramasivam:

    Hi Socrates,

    Sorry for not being able to get back to you earlier. This is an unexpected behavior. Could you please let us know the exact address where you are allocating the buffer and how the DSP is accessing the A15 non-cached region? This will help us understand this better.

    Thanks and Regards,

    Piyali
