PROCESSOR-SDK-J721S2: vx_print in tiovx kernel process codes

Juhyun Kim

Part Number: PROCESSOR-SDK-J721S2

Tool/software:

Hello Ti experts,

Can I see vx_print's outputs of TIOVX Kernel Process on A72 Linux Uart serial terminal?

I'd like to see add some prints in some TIOVX kernels like display, tidl, etc for debug purpose.

Regards,

Juhyun

    Hi Juhyun,

      Yes, you can see vx_print's output in uart terminal.

    Hi Gokul,

    I'd like to trace tivxKernelDrawBoxDetectionsProcess by adding some vx_print on it.

    Could you let me know which source code should I look at?

    Regards,

    Juhyun

    Hi Juhyun,

      call the funtion tivx_set_debug_zone(VX_ZONE_INFO);
      inside tivxKernelDrawBoxDetectionsCreate()
      refer https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/tiovx/docs/user_guide/DEBUG_PRINT.html

    then use this,
    VX_PRINT(VX_ZONE_INFO, "print... %d", int_variable);

    refer the source code in the following path
    $(PSDKR_PATH)/c7x-mma-tidl/arm-tidl/tiovx_kernels/tidl/dsp/vx_tidl_target.c

    Hi Gokul,

    I modified tivxKernelDrawBoxDetectionsCreate() as you said.

    static vx_status VX_CALLBACK tivxKernelDrawBoxDetectionsCreate
(
    tivx_target_kernel_instance kernel,
    tivx_obj_desc_t *obj_desc[],
    vx_uint16 num_params,
    void *priv_arg
)
{
    vx_status status = VX_SUCCESS;
    uint32_t i;

    tivx_set_debug_zone(VX_ZONE_INFO);

    for (i = 0U; i < num_params; i ++)
    {
        VX_PRINT(VX_ZONE_INFO, "print... %d", i);
        VX_PRINT(VX_ZONE_ERROR, "print... %d", i);
        if (NULL == obj_desc[i])
        {
            status = VX_FAILURE;
            break;
        }
    }

    return(status);
}

    But still the message doesn't appear.

    In the above log, I can see below message which I added on the tiovx/source/framework/vx_node.c

    VX_ZONE_ERROR:[vxReplicateNode:2043] reference type is object array

    I checked the source code is compiled as below.

    If i'm right, the compiled objects integrated in vx_app_rtos_linux_c7x_2.out and I updated the firmware binary and rebooted.

    Even to check whether the firmware updated, I remarked the contents inside 

    tivxAddTargetKernelDrawBoxDetections().

    void tivxAddTargetKernelDrawBoxDetections()
{
#if 0
    vx_status status = (vx_status)VX_FAILURE;
    char target_name[TIVX_TARGET_MAX_NAME];
    vx_enum self_cpu;

    VX_PRINT(VX_ZONE_ERROR, "tivxAddTargetKernelDrawBoxDetections!!\r\n");
    self_cpu = tivxGetSelfCpuId();

    if (self_cpu == TIVX_CPU_ID_MPU_0)
    {
        strncpy(target_name, TIVX_TARGET_MPU_0, TIVX_TARGET_MAX_NAME);
        status = (vx_status)VX_SUCCESS;
    }
    else
    {
        status = tivxKernelsTargetUtilsAssignTargetNameDsp(target_name);
    }

    if( (vx_status)VX_SUCCESS == status)
    {
        vx_DrawBoxDetections_kernel = tivxAddTargetKernelByName
                                     (
                                        TIVX_KERNEL_DRAW_BOX_DETECTIONS_NAME,
                                        target_name,
                                        tivxKernelDrawBoxDetectionsProcess,
                                        tivxKernelDrawBoxDetectionsCreate,
                                        tivxKernelDrawBoxDetectionsDelete,
                                        NULL,
                                        NULL
                                     );
    }
#endif
}

    And rebuilt, updated firmware, reboot, then executed demo application I got the result as below.

    So I know the modification of the source code is in effect, but still don't know why the vx_print doesn't show up.

    Regards,

    Juhyun

    Hi Gokul,

    I have found this thread,

    https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1442815/am62a3-how-to-view-the-logged-information-printed-in-the-c7x-dsp-after-connecting-to-the-board-via-ssh?tisearch=e2e-sitesearch&keymatch=C7%252520DSP%252520print#

    And following the answer, I executed  /opt/vx_app_arm_remote_log.out and I could see the prints from dsp.

    Thank you for the support.

    Regards,

    Juhyun
