TDA2HG: Deviation of color after DSSM2M link

Part Number: TDA2HG

Hi,

My visionSDK version: 3.05.

Here is my link: qt->weston(rgb)->dssm2m(yuv422)->display

I capture picture from weston(which I read from drm device) like this:

But after DSSM2M to display link the picture like this:

Here is my DSSM2M configure:

       /* DSS M2M WB link */
    pPrm->enableOut = TRUE;
    pPrm->wbInNode = DSSM2MWBLINK_DISPC_WB_IN_NODE_LCD2;
    pPrm->numInPipeLines = 1U;
    pPrm->inPipelines[0U] = DSSM2MWBLINK_DISPC_PIPE_VID2;

    /* input pipeline parameters */
    pPrm->inTarWidth[0U] = displayWidth;
    pPrm->inTarHeight[0U] = displayHeight;
    pPrm->inPosX[0U] = 0U;
    pPrm->inPosY[0U] = 0U;

    /* The overlay width and height are used only if 'wbInNode' is overlay node */
    pPrm->ovlyWidth = displayWidth;
    pPrm->ovlyHeight = displayHeight;

    /* Output parameters */
    /* Input format is ARGB32 and output format is YUV420SP_UV */
    pPrm->outDataFmt = SYSTEM_DF_YUV422I_UYVY;
    pPrm->outWidth = displayWidth;

So is there any problem that DSSM2M will lost presion when convert RGB to YUV?

Thanks!

Hi Tim,

There is a CSC module, which will convert first RGB into YUV format and then to YUV422 format. It may be that the CSC coefficients are not matching with the requirement of the source.

There is an SW interface to change CSC coefficients, could you please try changing it?

Hi Brijesh,

I captured picture after DSSM2M，it has no deviation.

I put below sample picture into DSSM2M link.

Then got picture after DSSM2M below:

It same as sample picture. But after put it to display link, I got picture below:

I put two arrows on picture to point out that red spot.

So Is it possible that display link lost presion?

Thanks!

Hi,

ok, what is the output interface from display? Are you using YUV422 discrete sync output interface? In this case, we need to configure DSS in RGB565 input format and disable all pixel processing modules.. So could you please pipeline modules?

Regards,

Brijesh

Hi,

Output interface is vout1. I already pipeline modules use visionsdk. Like said before qt->weston(rgb)->dssm2m(yuv422)->display. Here is usecase below:

And using YUV422 discrete sync output interface as rgb565 into display link.

We only edit these code:

Int32 DisplayLink_drvDisplayCreate(DisplayLink_Obj *pObj)
{
....
   if(dssPrms->inFmt.dataFormat == SYSTEM_DF_YUV422I_UYVY)
    {
        /* Convert to BGR565 output */
        dssPrms->inFmt.dataFormat = SYSTEM_DF_BGR16_565;
        Vps_printf("Andy: treat SYSTEM_DF_YUV422I_UYVY to SYSTEM_DF_BGR16_565 for display out\n ");
    }
....
}

Is it need change other place?

Hi,

I got patchs file from FAE, and compared the code, it seems no different. So I think it must have some other place need be configured.

Hi,

Please make sure that the input format is RGB565, all pixel processing modules are disabled/bypassed and finally, the TDM module is enabled for an 8bit output format. Without these changes, we cannot get YUV422 over a discrete sync interface.

Thanks

Hi Gaviraju,

I checked that already and I think if I missed one of it, there will no display on screen not just some red or green spots on it.

Thanks!

Hi Tim,

Can you please take dump of DSS registers and share it? I will check to see if there is something wrong.

Hi Tim,

The register settings are correct, you are selecting 16bit output and then using TDM, you are setting 16 bit pixel on two clock cycle over 8bit interface.

can you also please take a dump of DISPC_DATA1_CYCLE1, DISPC_DATA1_CYCLE2 and DISPC_DATA1_CYCLE3 registers? This will tell exactly bits are going out on each clock cycle.

Also can you please share the register values of the pipeline you are using?

Hi Brijesh,

For DISPC_DATA1_CYCLE1, DISPC_DATA1_CYCLE2 and DISPC_DATA1_CYCLE3:

| 0x580011DC    | 0x00000000 |

For register values of the pipeline, I not sure if it is only vid2 which we use as output. I dump those related registers below:

Hi Tim,

The data cycle is setup correctly.

But looks like VID2 is not used, as it is not enabled.

Can you please take dump of VID1/2/3_ATTRUBITE register and also GRPX_ATTRIBUTE register?

Could you also please tell what is the input format? is it YUYV (Luma in lower byte) or UYVY (U in lower byte)?

Regards,

Brijesh

Hi Brijesh,

Sorry, Tim is busy with other tasks.

The video input format is YUYV, and dumped some registers.

For VID1/2/3_ATTRUBITE register:

Read at address 0x580010CC (0xb6f950cc): 0x0208880D
Read at address 0x5800115C (0xb6f3d15c): 0x42088811
Read at address 0x58001370 (0xb6f80370): 0x00008400

I did not find the GRPX_ATTRIBUTE register you mentioned. This is the DISPC Registers status.

Hi Sans,

Could you please share me your input YUV order? I mean is Luma stored in lower byte of chroma?

In this technique, DSS will send out second byte first, then LSB. So if you are storing Luma in lower byte, then chroma would be sent out first. and if you are storing chroma in lower byte, then luma would be sent out first.

Please check your input YUV422 ordering and your expected byte ordering on the receiving end.

Regards,

Brijesh

Hi Brijesh,

Sorry, can you tell me how to confirm the input YUV order?

I try to change the order of yuv format pictures directly by 16 bytes or 32 bytes little-endian to big-endian. The picture color is obviously different.

If it is yuv byte misalignment, shouldn't the whole image display abnormally?

Thanks.

Hi Sans,

Could you please tell which component are using to get YUV422 output format? is it VPE or DSS WBM2M used to get YUV422 output format?

Hi Brijesh,

We use DSS WBM2M to convert RGB to YUV422.

Thanks.

Hi Sans,

Can you please check what is the output formats set in the DSS WBM2M path? You could even try reading WB_ATTRIBUTE register.

If Format field in this register is set to 0xB,ie, UYVY format, luma will be sent out on the first clock cycle. But if it is set to 0xA, ie YUYV format, chroma will be sent out on the first clock cycle.

So could you please check and format and change according to your receiver requirement?

Regards,

Brijesh

Hi Brijesh,

The dump register result is as follows:

omapconf read 0x58001570
00290A37

FORMAT: 0xF, xRGB15-1555

I think this is because of the modification in the code mentioned earlier:

Int32 DisplayLink_drvDisplayCreate(DisplayLink_Obj *pObj)
{
....
   if(dssPrms->inFmt.dataFormat == SYSTEM_DF_YUV422I_UYVY)
    {
        /* Convert to BGR565 output */
        dssPrms->inFmt.dataFormat = SYSTEM_DF_BGR16_565;
        Vps_printf("Andy: treat SYSTEM_DF_YUV422I_UYVY to SYSTEM_DF_BGR16_565 for display out\n ");
    }
....
}

Thanks.

Hi Sans,

Can you read register value at 0x58001570 and share it?

Hi Brijesh,

The previous omapconf read command can also dump registers.

This is the register value dumped:

root@dra7xx-evm:~# devmem2 0x58001570
/dev/mem opened.
Memory mapped at address 0xb6f56000.
Read at address 0x58001570 (0xb6f56570): 0x00290A36

The attachment is the status value of all DISPC registers.

Hi Sans,

It is set to output in UYVY format, which means DSS will send out luma on the first clock cycle. Is it what is expected by your receiver?

Can you try changing output format from DSS WBM2M to value 0xA, by changing output format in DSS M2M driver?

Lets say if you are using output format as FVID2_DF_YUV422I_YUYV, then change it to FVID2_DF_YUV422I_UYVY or vice versa...

Regards,

Brijesh

Hi Brijesh,

After UYVY is converted to YUYV, the image color is abnormal.

Sorry, the description of the previous problem is wrong.
The color deviation of the previous test picture is because the RGB format of the screenshot software is incorrect.
Please ignore the color cast test picture.

The output image is like this:

The display on the screen is like this, a green halo appears on the white wall.

You can see some of the photos, in fact, the halo eyes on the screen can clearly see.

Please pay attention to this kind of spots and halos.

Thanks.

Hi Sans,

oh ok. I got confused with the color charts that has been shared earlier.

I am really doubtful that these artifacts are coming from DSS. DSS does not change pixel values only for part of the frame.

Can you please save input to the DSS M2M WB driver and see if that looks correct? I am doubting that the input to the DSS itself has artifacts. so can you please check the input first?

Regards,

Brijesh

Hi Brijesh,

I saw that Tim’s previous reply has done a similar operation.

The images before and after M2M are normal.Currently, only put it to display link display will cause problems.

Thanks.

Hi Sans,

But at that time, the doubt was on the color being completely wrong. Since now you have confirmed that color are correct, but there is some artifacts, so i want you to check if the input & output of DSS M2M WB is correct. I really doubt that halo artifacts could be introduced by DSS.

Also can you use the gel file from vision_sdk\ti_components\drivers\pdk_01_10_02_07\packages\ti\drv\vps\docs\tda2xx\TDA2xx_Dss_RegDump.gel and dump all DSS registers and share it?

Could you also share which VP output is used for DSS M2M WB and which for sending out over BT format? Which video pipelines are used in this case?

Rgds,

Brijesh

Hi Brijesh ,

Sorry for late reply.

Since now you have confirmed that color are correct, but there is some artifacts, so i want you to check if the input & output of DSS M2M WB is correct. I really doubt that halo artifacts could be introduced by DSS.

Sorry Brijesh, I'm don't know how to check input & output of DSS M2M WB is correct. Since I showed pictures on second floor of this thread, I can't see any different. Will halo artifacts happen when DSS out over BT formate?

I didn't have CSSStudio, so I can't use TDA2xx_Dss_RegDump.gel to dump register. I use devmem2 to dump it, hope it not hard for you to read.

And I use vout1 for sending out over BT format, and vout2 for DSS M2M WB. Video pipelines is VID1

Hi Tim,

I see two changes that can potentially change your output on the BT601 format.

1, DISPC_DEFAULT_COLOR0 (0x5800104C) is not set 0x0, please set it to 0x0.

2, I think VID1 is connected to LCD1 and LCD1 is used for the BT601 output format. But z-order is enabled in the vid1. Please disabled z-order in VID1.

Regards,

Brijesh

Hi Brijesh,

Follow your suggestion, I editored configuration below:

/dev/mem opened.
Memory mapped at address 0xb6f9a000.
Read at address 0x5800104C (0xb6f9a04c): 0x00000000
2.

But the problem remain.

Hi Tim,

It would be very difficult to figure out, unless we know how is the input. I checked the registers, it looks fine. So could you try saving the input frame and check the input itself is correct?

Regards,

Brijesh

Hi Brijesh,

Yes, I'll dump input frame and output frame in receive site. Any discovery I'll share here.

Thanks!

Hi Brijesh,

I dumped input frame and output frame in receive site here: dumprx.rardumptx.rar is input frame and dumprx.rar is output frame.

There are two kinds of deviation color dot: 1. more blue dot; 2. block dot;

Hi Brijesh,

I use 24 colors card to test again and capture one picture of display video:

dumppic.rar

The difference seems only happened on Y plane and only flip at 5th bit. For example: Tx Y: 0xD0, Rx Y: 0xC0.

dumprx1_pic.yuv: receive site after ub964 dumped data. Formate: YUYV422I. 1920x720

dumptx1_pic.yuv: send site before display link dumped data. Formate: UYVY422I. 1920x720

Hi Tim,

The bit can change only because of the below reasons

1, Background color, can you please make sure that the background color is set to 0x0 for the LCD output?

2, Transparency, can you please make sure that the transparency is disabled for the LCD output?

3, pinmux, please make sure that pinmux is setup correctly and is not getting overwritten by other SW component. While display is running, you could read back the pinmux register for all data pins to make sure it is correct and unaffected.

Hi Brijesh,

Thanks for your reply!

Sorry, I forget change my background color setting. After that 24 color card much better now, but still have some flip:

dump.rar

here is my settting:

    /* Setting other overlay parameters common to both Venc */

    ovlyPrms->deltaLinesPerPanel   = 0;
    ovlyPrms->alphaBlenderEnable   = 0;
    ovlyPrms->backGroundColor      = 0;
    ovlyPrms->colorKeyEnable       = 0;
    ovlyPrms->colorKeySel          = SYSTEM_DSS_DISPC_TRANS_COLOR_KEY_SRC;
    ovlyPrms->ovlyOptimization     = SYSTEM_DSS_DISPC_OVLY_FETCH_ALLDATA;
    ovlyPrms->transColorKey        = DRAW2D_TRANSPARENT_COLOR;

    /* Setting overlay pipe parameters */

    pipeOvlyPrms[0].pipeLine = SYSTEM_DSS_DISPC_PIPE_VID1;
    pipeOvlyPrms[0].globalAlpha = 0xFF;
    pipeOvlyPrms[0].preMultiplyAlpha = 0;
    pipeOvlyPrms[0].zorderEnable = FALSE;
    pipeOvlyPrms[0].zorder = SYSTEM_DSS_DISPC_ZORDER0;

    pipeOvlyPrms[1].pipeLine = SYSTEM_DSS_DISPC_PIPE_VID2;
    pipeOvlyPrms[1].globalAlpha = 0xFF;
    pipeOvlyPrms[1].preMultiplyAlpha = 0;
    pipeOvlyPrms[1].zorderEnable = FALSE;
    pipeOvlyPrms[1].zorder = SYSTEM_DSS_DISPC_ZORDER1;

    pipeOvlyPrms[2].pipeLine = SYSTEM_DSS_DISPC_PIPE_VID3;
    pipeOvlyPrms[2].globalAlpha = 0xFF;
    pipeOvlyPrms[2].preMultiplyAlpha = 0;
    pipeOvlyPrms[2].zorderEnable = FALSE;
    pipeOvlyPrms[2].zorder = SYSTEM_DSS_DISPC_ZORDER2;

    pipeOvlyPrms[3].pipeLine = SYSTEM_DSS_DISPC_PIPE_GFX1;
    pipeOvlyPrms[3].globalAlpha = 0xFF;
    pipeOvlyPrms[3].preMultiplyAlpha = 0;
    pipeOvlyPrms[3].zorderEnable = FALSE;
    pipeOvlyPrms[3].zorder = SYSTEM_DSS_DISPC_ZORDER3;

For Transparency, would you please tell me which register should I check? I guess it may be the missed setting.

For pinmux, I checked CTRL_CORE_PAD_VOUT1_D* :

Hi Tim,

Can you please check the bit-10 (TCKLCDENABLE) in DISPC_CONFIG register for the LCD output that you are using?

Can you also check the background color in the register to confirm if it is set to 0?

Check these registers when display is running..

Hi Brijesh

Tim is away temporarily, I helped him to confirm.

We are using LCD1 and I checked the bit-10 (TCKLCDENABLE) in DISPC_CONFIG(0x58001044) value is 0.

root@dra7xx-evm:~# omapconf dump 0x58001044 0x58001048
|----------------------------|
| Address (hex) | Data (hex) |
|----------------------------|
| 0x58001044 | 0x00000804 |
| 0x58001048 | 0x00000000 |
|----------------------------|

The background color register(0x5800104C) setting is also 0.

root@dra7xx-evm:~# omapconf dump 0x5800104C 0x58001050
|----------------------------|
| Address (hex) | Data (hex) |
|----------------------------|
| 0x5800104C | 0x00000000 |
| 0x58001050 | 0x00000000 |
|----------------------------|

The register value looks correct.

Thanks!

Hi Sans,

Could you also please make sure that the ZORDER bit in the attribute register of the video pipeline you are using to send out the YUV data is set to 0? this will make sure that the blending is also disabled. Please check this register while display is running..

Hi Brijesh,

Thanks for your quick reply!

Could you also please make sure that the ZORDER bit in the attribute register of the video pipeline you are using to send out the YUV data is set to 0?

we use DISPC_VID1_ATTRIBUTES(0x5800 10CC):

root@dra7xx-evm:~# devmem2 0x580010CC
/dev/mem opened.
Memory mapped at address 0xb6fdd000.
Read at address  0x580010CC (0xb6fdd0cc): 0x0008880D

but we use DISPC_VID2_ATTRIBUTES(0x5800 115C) as m2mwbLink:

root@dra7xx-evm:~# devmem2 0x5800115C
/dev/mem opened.
Memory mapped at address 0xb6f0a000.
Read at address  0x5800115C (0xb6f0a15c): 0x42088810

Should I chonfigure DISPC_VID2_ATTRIBUTES ZORDER bit also?

this will make sure that the blending is also disabled.

Is it LCDALPHABLENDERENABLE bit on DISPC_CONFIG(0x58001044) ? San show it " 0x00000804", so it is disabled already.

Thanks!

Hi Tim,

Yes, if you are just connecting only one pipeline to the LCD where VID2 is connected, please disable it for VID2 also. Please also set the background color to 0x0 for LCD2.

Hi Brijesh,

I only use VID2 as M2M write back to convert RGB to YUV and use VID1 as display.

Anyway, I disabled ZORDER bit in DISPC_VID2_ATTRIBUTES(0x5800 115C) but problem still:

And DISPC_DEFAULT_COLOR2(0x5800 13AC) is also 0:

root@dra7xx-evm:~# devmem2 0x580013AC

Hi Brijesh,

I quite confirm that one bit flip is on the dispaly path. As I told, I dumped picture after DSS WB M2M and dumped picture after display path, then make those compare and found one bit flip. Picture after display path have deviation problem.

Hi Tim,

Do you mean you capture and dumped output from SERDES and then compare it against input?

Does DSS WB M2M path output look fine?

Let me also again go through the register dump that you have shared earlier.
