Hi,

When i send the "System_linkControl" API the cycle of 500ms, sometimes the "GrpxSrcLink_tskMain" received the data late.

I send the API as below,

===========================================================

Vps_printf("Send the System_linkControl !! \r\n");
System_linkControl(chainsObj.ucObj.GrpxSrcLinkID,
                      GRPX_SRC_LINK_CMD_NO_CAMERA,
                      &GrpxInfo,
                      sizeof(GrpxInfo),
                      TRUE);

===========================================================

In the log, the data received 600ms or 700ms delay.

I must receive the data at regular intervals.

How could i fix this issue ?

Regards,

Lee

Hi,
There is no such command is avaliable in gprx src link.
Have you added your own command.

It is possible because of the load of the core.
Can you please check the load.
I hope you are adding the log just after you are receiving the command.
Please add sleep after prints and check the timing.

Anuj

Hi Anuj,

Thanks for reply.
First, My test environment is checking in "csi2_cal_sv_standalone" and it is in debug mode.

1) Yes, I added a new command to display the new grpx for my UI.
Below is a log of the current system load you requested.

2) I measured the log on "GrpxSrcLink_tskMain" and the delay is still generated.

3) My current concept is that the button UI should be displayed immediately for button display.
No delay should occur.
I don't understand that you said "Please add sleep after prints and check the timing".
Do you want to test the code below?

Lee

Hi,

Can you try out the same experiment in the below usecase and check whether you are getting the same delay or not?

vision_sdk\apps\src\rtos\usecases\vip_single_cam_view

Hi Anuj,

Thanks for reply.
Sorry, The board was made to fit our system. So, the board does not have VIP port.
Could i try the chains_csi2CalMultiCam ?

\PROCESSOR_SDK_VISION_03_03_00_00_HD-AVM\vision_sdk\apps\src\rtos\usecases\csi2_cal_multi_cam_view

Hi Anuj,

In the "chains_csi2CalMultiCam" Application, the delay isn't observed.
The message transmission is completed within 20ms.

However, Although i know that many tasks are used in TI-SV, i think that the delay(600~700ms) takes too long.
Is there a way to solve this problem ?
Is it possible to change the priotiry of a Grpx task ?

Regards,
Lee

Hi,

You can change the priority by changing the 3rd line of the below api.

        status = Utils_tskCreate(&pObj->tsk,
                                 GrpxSrcLink_tskMain,
                                 GRPX_SRC_LINK_TSK_PRI,
                                 gGrpxSrcLink_tskStack[grpxSrcId],
                                 GRPX_SRC_LINK_TSK_STACK_SIZE, pObj, pObj->name,
                                 UTILS_TSK_AFFINITY_CORE1);
