TDA4VM: TDA4VM Rtos 0806: Does C6x_1/2 affect the video channel?

Part Number: TDA4VM

Tool/software:

Hi,

        After adding some small algorithms to DSP (C6x_1 cpu: 20%),
image flickering occurs in CAMERA->VIDEO->DSS.

1. Is this possible?
2. Or  can disable the TIOVX function of C6x_1/2 ？
thanks

    May I know where is C66 in this?

    DO you mean you do not want to run vision_apps firmware on these cores?

    HI,

    Use 1 C66 for audio，and  used IPC.
    C66_1 and C66_2 all have the func，

    {&tivxAddTargetKernelDLColorConvert, &tivxRemoveTargetKernelDLColorConvert},
    #endif
    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

    Can I delete these functions in C66_2 without affecting the vision apps?

    thanks

    Hi,

    yes, if you are not using this, then you are remove the same.

    Additionally, if you are not using C66x cores for vision_apps, you can remove the whole this for the same by below 2 steps.

    Step 1: in vision_apps/platform/j721e/rtos/common/app_cfg.h, you can comment out ENABLE_IPC_C66x_1 and 2

    Step 2: in sdk_builder/vision_apps_build_flags.mak you can change BUILD_CPU_C6x_1 and 2 to "no"

    With this, vision_apps binaries are not connected to C66x core

    Regards,

    hi, 
    I don't want to delete the core c66x_1 and 2,

    like above, 
    when enable audio alg, will make display flicker, 
    so delete the c66x_2 some or all tiovx func, It's possible?

    thanks
