TMDSCSK388: Display Link Error

Thank you Brijesh

I added scalar in second capture output, created scalar link.  I'm posting the modifications. Display link is still having some issues. Can you please verify.

CaptureLink_CreateParams_Init(&capturePrm);

capturePrm.outQueParams[0].nextLink = ipcOutVpssId;

capturePrm.outQueParams[1].nextLink = gVcamModuleContext.sclrId[0];

capturePrm.tilerEnable = FALSE;

pCaptureInstPrm = &capturePrm.vipInst[0];

pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP0_PORTA;

pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;

pCaptureInstPrm->standard = SYSTEM_STD_1080P_30;

pCaptureInstPrm->numOutput = 2;

/* First stream */

pCaptureOutPrm = &pCaptureInstPrm->outParams[0];

pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422P;

pCaptureOutPrm->scEnable = FALSE;

pCaptureOutPrm->scOutWidth = 1920;

pCaptureOutPrm->scOutHeight = 1080;

pCaptureOutPrm->outQueId = 0;

/* Second stream */

pCaptureOutPrm = &pCaptureInstPrm->outParams[1];

pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422P;

pCaptureOutPrm->scEnable = FALSE;

pCaptureOutPrm->scOutWidth = 1920;

pCaptureOutPrm->scOutHeight = 1080;

pCaptureOutPrm->outQueId = 1;

/* scalar */

SclrLink_CreateParams_Init(&sclrPrm);

sclrPrm.inQueParams.prevLinkId = gVcapModuleContext.captureId;

sclrPrm.inQueParams.prevLinkQueId = 1;

sclrPrm.outQueParams.nextLink = gVdisModuleContext.displayId[VDIS_DEV_SD];

sclrPrm.tilerEnable = FALSE;

sclrPrm.enableLineSkipSc = FALSE;

sclrPrm.inputFrameRate = 30;

sclrPrm.outputFrameRate = 30;

sclrPrm.scaleMode = DEI_SCALE_MODE_ABSOLUTE;

sclrPrm.outScaleFactor.absoluteResolution.outWidth = 720;

sclrPrm.outScaleFactor.absoluteResolution.outHeight = 480;

sclrPrm.outDataFormat = VF_YUV420SP_UV;

sclrPrm.pathId = SCLR_LINK_SEC0_SC3;

// display link params

MULTICH_INIT_STRUCT(DisplayLink_CreateParams,displayPrm_SD);

displayPrm_SD.inQueParams[0].prevLinkId = gVcamModuleContext.sclrId[0];

displayPrm_SD.inQueParams[0].prevLinkQueId = 0;

displayPrm_SD.displayRes = gVdisModuleContext.vdisConfig.deviceParams[VDIS_DEV_SD].resolution;

displayPrm_SD.displayId = DISPLAY_LINK_DISPLAY_SD;

Thank you and Regards.

Hi Nithin,

Does it still fail at the same place?

Are you sure that the SD path is not being used by any other driver? 

Can you please check if it works for YUV422 output from Scalar?

Hi Brijesh,
1.Does it still fail at the same place?
The display link is not created successfully. Now there is a warning message at the log: MSGQ: WARNING: Trying to send command [0x0000] to link [0] on processor [DSP], BUT [DSP] is NOT present on this platform
and the place failing is different: Assertion @ Line: 220 in links_common/system/system_ipc_msgq.c: 0 : failed !

2.Are you sure that the SD path is not being used by any other driver?
I'm customizing the Dm388_CSK application. if the SD path is configured only in the usecase folder, I think then no other driver is using the SD path

3.Can you please check if it works for YUV422 output from Scalar?
I checked with YUV422 still that does not resolve the problem.

Thank you,

Hi Nithin,

Can you please check where exactly it fails? it is trying to send message to DSP, which seems not active. Can you please trace in the usecse?

Hi Brijesh

This is Link create for my display in Usecase. I have kept an Led On function after the display link create, which is not turning ON. As well as the "usecase setup done" is also not printing.

Error message is : Assertion @ Line: 220 in links_common/system/system_ipc_msgq.c: 0 : failed

{
.......................................
.......................................
/* Scaler Link */
System_linkCreate(gVcapModuleContext.sclrId[0], &sclrPrm, sizeof(sclrPrm));
gpio_led_on(26);

/* display link */
System_linkCreate(gVdisModuleContext.displayId[VDIS_DEV_SD], &displayPrm_SD, sizeof(displayPrm_SD));
gpio_led_on(27);


OSA_printf("USECASE SETUP DONE\n");
}


Thank you,
Regards.
