DVO2 color bar on DM385

The echo command should send the number of active pixels and not the number of pixel clocks.

echo 27000,1440/36/240/1,480/1/21/1,1 > /sys/devices/platform/vpss/display1/timings

The highlighted should be 720 i believe. the clock doubling is handled by the format specifier.

Additionally, the numbers do not match what you said for the LCD specification. You say 960x240 interlaced but then use 720*2 (=1440).

You are also setting the vertical resolution to 240 but specifying interlaced. You need to check with the LCD datasheet EXACTLY what input format it can accept.

I think you have quite a few things incorrect here but the LCD datasheet should clarify how things need to be set. Does the datasheet mention ITU656 (BT656) or some similar standard format for the interface?

Finally the horizontal numbers don't add up correctly in the spec. What is 'dummy' time?

Hi steve, Thanks you for your reply.

I fix the echo command :

echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 27000,960/36/240/1,240/1/21/1,0 > /sys/devices/platform/vpss/display1/timings
echo single,yuv422spuv,0/0/1/1 > /sys/devices/platform/vpss/display1/output
echo 1 > /sys/devices/platform/vpss/display1/enabled

but now LCD diplay below:

Try 720. As I mentioned previously there is something wrong with the LCD specification numbers.

In one place it says 960 pixels but then in another it says total clocks per line = 1716. With an 8 bit interface each pixel needs 2 clocks so 960 pixels needs at least 1920 clocks which is greater than the specified 1716.

I think you need to check back with the LCD manufacturer for a more complete/correct datasheet.

BR,

Steve

Hi Steve,

You are right about the LCD spec.

My coworker integrated DM36x and this LCD successfully.

He suggests me to implement the “Serial YUV422 mode” (BT601) timing followed:

 The latest register dump is :

0x4810a000 45A0B059
0x4810a004 003F0275
0x4810a008 1EA500BB
0x4810a00c 1F9901C2
0x4810a010 1FD71E67
0x4810a014 304001C2
0x4810a018 FF200200
0x4810a01c 184C0C77
0x4810a020 1C0C0C30
0x4810a024 1C0C0C30
0x4810a028 8420D6B3
0x4810a02c 010A6016
0x4810a030 015A00EE
0x4810a034 00000139
0x4810a038 00038338
0x4810a03c 015A00F0
0x4810a040 00015000
0x4810a044 000F0015
0x4810a048 010000F0
0x4810a04c 01000000
0x4810a050 00000000
0x4810a054 015A00F0
0x4810a058 00015000
0x4810a05c 000F0015
0x4810a060 010000F0
0x4810a064 01000000

And the wrong color bar is :

Could you possibly send me the LCD datasheet/ I think something is not configured on the LCD.

It looks like the LCD might be expecting serial RGB instead of serial YUV422.

BR,

Steve

Steve

LCD spec is attached.

Its maker is lnnolux (not TOP) now.

BTW. we use LCD's default power on register settings as the I2C-like control I/F are disconnected.

0880.990000270 (LCJ025T003A) Spec V1 1-2009-01-05.pdf

First, I would suggest always connecting the control interfaces to any external devices. This would be useful in debugging this issue.

OK, make sure that the H-sync and V-sync polarities being output from the DM385 are correct. They should be set to negative.

Make sure that the DM385 is configured to transition output data on the positive edge of the data clock since the LCD captures on the falling edge bu default.

If possible connect the I2C for the LCD so that you can experiment with LCD parameters, in particular register 3 bits 3:2 which control the expected format ordering.

BR,

Steve

Steve

The LCD timing chart is attached.

Is it right ?

1817.LCD_SCOPE.tar.gz

Steve

I have inversed the data clock, but the color is same.

I think this is an LCD mis-configuration but it is very difficult to debug remotely.

Try inverting the H-sync polarity.

Try increasing the horizontal front porch by 1 whilst decreasing the back porch by 1. This shouldn't make a difference but it may shift the relationship between Y & C.

BR,

Steve

Hi Steve,

Thank you for your suggest, I will try to configure LCD.
then response to the result.

BTW. The LCD interface is spi, I tried enable spidev on user space but fail.
can you help me about this ? Thank you again.

Hello Steve

The color bar now is corrected.

but I need set the LCD YCbCr sequence register: YCrYCb
BT 656 standard YCbCr sequence should be CbYCrY.
why the DM385 output do not meet ? or have register can be set ?

I think this is most likely a mis-alignment between the 2 devices.

The DM does output a standards compliant 656 stream, but incorrect h-sync parameter settings can shift the apparent phase.

I recommend checking that all pixels are being displayed correctly by displaying a single pixel wide outer box and making sure you can see all outer edge pixels correctly.

BR,

Steve

Hi Steve

Please let me know the register address that can change the pixel clock polarity of DVO2 ?

My HDVPSS document is "SPRUH17 December 2012"

Thanks in advance. 

Hi vic lin:

    I've meet the issue same with you on DM385,Can you post me the detail modifications to get the correct color bar?

Hi vic lin:

    Thanks very much for your  warmly  help! I'm sorry to replay you so late.

    I've set my DVO2 registers as your sugest but it is not useful for me. The only thing changed is there is no video

   output When I set reg 0x4810a028 to 0x8420D35A. I think i need to check our's registers configuration carefully.

    Thanks again!

ST

Why are you changing offset 028h? This register controls the total number of pixels per line.

CFG0 is at address offset 0 so you need to set bit 15 of address 0x4810a000.

Steve

ST,

Register settings are not the way to debug this.

We need to start from scratch with your issue since there are many, many things that can cause this issue.

Can you possibly post the datasheet for the LCD you are trying to connect to, and the steps that you have followed to try to get the display working?

BR,

Steve

Hi Steve:

    Thanks very much for you attention.

   My color bar is not displayed on LCD but output to a SDI receiver GS2972 by DVO2 interface and then displayed on a

   monitor. I only need to confiure the SDI receiver for 10bit data mode and SD display mode for 480I, I was forget to

  told you that. I'm sorry.

   I develop DM385 based on SDK dvr-rdk-4.0. and i use the VCAP + VDIS usecase for test. The dislpay is correct  

   When I input HD video such as 720P or 1080P. But the display is not correct for 480i.

   Below is the modification for external 480I  color bar input and display:

   demo_vcap_vdis.c:

   vdisParams.deviceParams[VDIS_DEV_HDMI].resolution   = VSYS_STD_480I;
    /* Since HDMI and DVO2 are tied together they must have same resolution */
    vdisParams.deviceParams[VDIS_DEV_HDCOMP].resolution = vdisParams.deviceParams[VDIS_DEV_HDMI].resolution;
    vdisParams.deviceParams[VDIS_DEV_DVO2].resolution   = vdisParams.deviceParams[VDIS_DEV_HDMI].resolution;
    vdisParams.deviceParams[VDIS_DEV_SD].resolution     = VSYS_STD_NTSC; 

    Vdis_tiedVencInit(VDIS_DEV_HDMI, VDIS_DEV_DVO2, &vdisParams); // We tied HDMI and DVO2

    multich_vcap_vdis.c

    pCaptureInstPrm->standard           = VSYS_STD_480I;
    pCaptureInstPrm->videoIfMode        = DEVICE_CAPT_VIDEO_IF_MODE_8BIT; 
    pCaptureInstPrm->videoCaptureMode   = DEVICE_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC;
    pCaptureInstPrm->inScanFormat = SYSTEM_SF_INTERLACED;  

    mcfw/interfaces/ti_vdis_timings.h

    #define VDIS_TIMINGS_480I_59   "27000,1440/38/114/124,480/4/15/3,0" //Add 480I timing

    mcfw/src_linux/mcfw_api/ti_vdis.c

    in fun Vdis_params_init:

    //pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoFmt = VDIS_DVOFMT_DOUBLECHAN;
    pContext->deviceParams[VDIS_DEV_DVO2].outputInfo.dvoFmt = VDIS_DVOFMT_SINGLECHAN;    // Set for 10bit mode

    in fun Vdis_setResolution:

    case VSYS_STD_480I:  // Add for 480I
           Vdis_sysfsCmd(3,VDIS_SYSFSCMD_SETTIMINGS, VDIS_SYSFS_HDMI, VDIS_TIMINGS_480I_59);
           Vdis_sysfsCmd(3,VDIS_SYSFSCMD_SETTIMINGS, VDIS_SYSFS_DVO2, VDIS_TIMINGS_480I_59);
    break;

   So, I  have not configure DVO2 register directly. 

   My monitor can recognise the 480i timming now, but the vidio data on screen is not correct:

   For the color bar of DVO2 :

   For the color bar of external input:

   Is there anything i did wrong or something i missed? I sincerly expect your help, Thank you very much.

BR

ST

I don't think it should be necessary for you to make any driver changes since SD 422 output should already be an option.

The color issue you are seeing is absolutely a miss-configuration of the color space at some point in your pipe.

Something somewhere is configured for RGB24 when it should be 422 or visa-versa.

I will try to get someone from the software team to help with your configuration.

Steve

Hi Steve:

Hi,

On DVR-RDK, the output might be set to RGB or YUV, so i would suggest first to make sure it is working fine with the sysfs entries. What is the input format expected by your LCD? I guess since the interface is 8bit embedded sync, it should be YUV422.

      0x4810a05c: 00120168 -> 00120150

    The display result as below:

So it look like work well for the self test colo bar. But when i input external 576I color bar for test, The display on monitor

is not correct, please see the attachment.

I have tested the capture link for 576I, It works well for caputre a correct video data.

Is there anything I missed for external 576I input and display? I need you help, thanks agian!

Good to hear that color bar test is working fine. Now it is just displaylink that we should make it working.

Did you check that when set_fmt ioclt is called, the frame size that is used is 720x576 and it is not getting reconfigured to any other resolution?

Also can you tell me which display path that you are using? I want to check the frame size set in the internal modules and make sure it is correct?

Hi,

Can you please share the register dump of 12 registers starting from the address 0x48105100? I want to make sure that the size configured in this module is correct..

Please also note that in your configuration, HDMI are DVO2 vencs are tied together, so HDMI should be configured with the same PAL resolution and should be clocked with the same clock source. Otherwise there could be issue in syncing these two vencs.

Regards,

Brijesh

Hi Brijesh:

    Below is the register dump:

     0x48105100: 00000020
     0x48105104: 00000000
     0x48105108: 00000000
     0x4810510c: 00000000
     0x48105110: 00000000
     0x48105114: 00000000
     0x48105118: 05A00120
     0x4810511c: 00000000
     0x48105120: 02D00120
     0x48105124: 00000000
     0x48105128: 00000000
     0x4810512c: 00000000

    Then i configure the output size register as below:

    0x48105104: 02d00240

    But it is unuseful for the display.

    I have set the HDMI output resolution as below:

    vdisParams.deviceParams[VDIS_DEV_HDMI].resolution   = VSYS_STD_576I;
    Demo_displaySetResolution(VDIS_DEV_HDMI, VSYS_STD_576I); 

    in file  demo_vcap_vdis.c, But i don't know how to configure the same clock with DVO2,Please show me the way.

   Thanks again.

   Best Regards,

   ST

Hi,

Can you try setting register at the offset 0x48105118 to 02D00120?

This register is set to 1440x288 resolution, but it should be set to 720x288.

Rgds,

Brijesh

Hi Brijesh:

    The display is still not correct when i set 0x48105118 to 02D00120.

    As you said,my be the output is depended on the configuration of HDMI  register.

    However,I don't  know what is the exact value of the hdmi register. I have configured  the HMDI register's as  DVO2,

    but its not work also.

    Can you sugest a good way for me to get the correct configuration of hdmi?

    Thank you very much.

   Best Regards,

   ST

Hi,

Instead of fixing hdmi, can we try disabling tying with HDMI and see if it works.

To disable tying, set tiedVencs in display controller tree to 0.

Regards,

Brijesh

Dear Brijesh:

    When i disable tied DVO2 with HDMI, there is nothing output.

    It works fine when i input 1080P or 720P video even tied DVO2 with HDMI.

    In file demo_vcap_vdis.c, I have set the same resolution with HDMI for DVO2:

    vdisParams.deviceParams[VDIS_DEV_HDMI].resolution   = VSYS_STD_576I
    /* Since HDMI and DVO2 are tied together they must have same resolution */
    vdisParams.deviceParams[VDIS_DEV_HDCOMP].resolution = vdisParams.deviceParams[VDIS_DEV_HDMI].resolution;
    vdisParams.deviceParams[VDIS_DEV_DVO2].resolution   = vdisParams.deviceParams[VDIS_DEV_HDMI].resolution;

    And in file mcfw/src_bios6/links_m3vpss/system/system_dctrl.c, I also set DVO2 and HDMI with the same clk src:    

        clkSrc.venc = VPS_DC_VENC_DVO2;
        clkSrc.clkSrc = VPS_DC_CLKSRC_VENCD;
        retVal = FVID2_control(
                     gSystem_objVpss.fvidDisplayCtrl,
                     IOCTL_VPS_DCTRL_SET_VENC_CLK_SRC,
                     &clkSrc,
                     NULL);

        UTILS_assert(retVal == FVID2_SOK);

        /* Set the Clock source for on-chip HDMI */
        clkSrc.venc = VPS_DC_VENC_HDMI;
        clkSrc.clkSrc = VPS_DC_CLKSRC_VENCD;
        // clkSrc is the same as DVO2 for this App
        retVal = FVID2_control(
                     gSystem_objVpss.fvidDisplayCtrl,
                     IOCTL_VPS_DCTRL_SET_VENC_CLK_SRC,
                     &clkSrc,
                     NULL);

          UTILS_assert(retVal == FVID2_SOK);

    Is there anything missed for this issue?

    Best Regards,

    ST

oh ok, if tying is working for other modes, it should work for 576i also. the above looks correct.

From the earlier register dump, still somewhere line length is set to 1440. This line length is returned by the venc hal layer and the frame size returned by this hal layer will be used to configure other pipe line modules.

If you have overlay/M3 source code, can you check where in code it is returning 1440 as the frame size.. there must be some api like getVencModeInfo for getting mode information. can you put break point in this api and check if it returns correct size.

Rgds,

Brijesh

In /dvr_rdk/mcfw/src_bios6/links_m3vpss/display/displayLink_drv.c

DisplayLink_drvSetResolution

before call to FVID2_setFormat

ensure pObj->displayFormat.scanFormat = FVID2_SF_INTERLACED is set.

Confirm that width and height are correctly set for 576I.

Also check this post where another customer has got PAL working on DVO2 on 816x using DVRRDK

RE: DM8168 McFW/Link API with one HDMI and two channel SD outputs

HI

   I already have debug the format information before call to FVID2_setFormat in displayLink_drv.c:

   Int32 DisplayLink_drvSetFmt(DisplayLink_Obj * pObj, FVID2_Format *pFormat)
   {
       Int32 status;

       /* For the DEI Display instances, set the DEI params */
       if (DisplayLink_drvIsDeiDisplayDrv(pObj))
       {
           Vps_printf("DISPLAY: -------------Dei Display------------");
           status = DisplayLink_drvSetDeiDispPrms(pObj, pFormat);
       }
       else
       {
           Vps_printf("DISPLAY: -------------Normal Display------------");
           status = FVID2_setFormat(pObj->displayHndl, pFormat);
       }

       Vps_printf("DISPLAY: ------------- pFormat->channelNum = %d ------------", pFormat->channelNum);
       Vps_printf("DISPLAY: ------------- pFormat->width = %d ------------", pFormat->width);
       Vps_printf("DISPLAY: ------------- pFormat->height = %d ------------", pFormat->height);
       Vps_printf("DISPLAY: ------------- pFormat->dataFormat = %d ------------", pFormat->dataFormat);
       Vps_printf("DISPLAY: ------------- pFormat->scanFormat = %d ------------", pFormat->scanFormat);
       Vps_printf("DISPLAY: ------------- pFormat->bpp = %d ------------", pFormat->bpp);
       Vps_printf("DISPLAY: -------------status = %d ------------", status);
       UTILS_assert(status == FVID2_SOK);
       return(status);
    }

    And the start log as below:

    [m3vpss ] Display Set fmt: pFormat->width = 720, pFormat->pitch[0] = 3840     
    [m3vpss ] DISPLAY: -------------Normal Display------------

    I set 576I timming to "27000,1440/24/138/126,576/2/15/19,0",Is it correct?

    I'll check these points as yours suggests,Thanks so much!

    Best Regards,

    ST

ST,

I believe 1440 should be 720. The timings settings are programmed in terms of pixels and not clocks I believe.

BR,

Steve

Yes, it should be 720. Is this solved by setting width to 720?

Regards,

Brijesh

Hi Brijesh:

    The monitor can not recognize the timming when i change1440 to 720 and nothing displaied.

    I have set the 576I timming to "27000,1440/24/138/126,576/2/19/3,0" after i checked the timing diagram

   and  the output result is better than before,but it is still not correct.

  I set the data path as below:

   Vps_DcConfig gSystem_dctrlTriDisplayConfig = {            //for test
    VPS_DC_USERSETTINGS,                                   /* Use Case */
    /* Edge information */
    {
     {VPS_DC_BP0_INPUT_PATH, VPS_DC_HDCOMP_MUX}     ,
     {VPS_DC_HDCOMP_MUX, VPS_DC_CIG_PIP_INPUT}      ,
     {VPS_DC_CIG_PIP_OUTPUT, VPS_DC_HDMI_BLEND}     ,
     {VPS_DC_CIG_PIP_OUTPUT, VPS_DC_DVO2_BLEND}     ,
     {VPS_DC_SEC1_INPUT_PATH, VPS_DC_SDVENC_MUX}    ,
     {VPS_DC_SDVENC_MUX, VPS_DC_SDVENC_BLEND}       ,
     {VPS_DC_GRPX0_INPUT_PATH, VPS_DC_HDMI_BLEND}   ,
     {VPS_DC_GRPX0_INPUT_PATH, VPS_DC_DVO2_BLEND}  ,
     {VPS_DC_GRPX2_INPUT_PATH, VPS_DC_SDVENC_BLEND}
    }

    ,
    9,
    /* VENC information */
    {
     /* Mode information */
     {
           { VPS_DC_VENC_HDMI, {FVID2_STD_1080P_60} 
           } ,                                                 

           {VPS_DC_VENC_DVO2, {FVID2_STD_1080P_60}
           } ,                                                

           {VPS_DC_VENC_SD, {FVID2_STD_NTSC}
           }
      }
      ,
      (VPS_DC_VENC_HDMI | VPS_DC_VENC_DVO2),                /* Tied VENC bit
                                                            * mask */
      3u                                                    /* Number of VENCs
                                                            */
     }

    I don't know whether it is correct or not.

    The display result is below:The monitor is flicker fast and the image is not full size displaied on monitor<Top and bottom>.

Hi Brijesh:

    I can get the correct output of 576I resolution sometimes.

    I configure the timming and clock as below:

    Timming : "27000,720/12/69/63,576/2/19/3,0"

    Clock: 0x48100114 -> 0x8000c

    clkSrc.venc = VPS_DC_VENC_DVO2;
    clkSrc.clkSrc = VPS_DC_CLKSRC_VENCD_DIV2_DIFF;
    retVal = FVID2_control(
        gSystem_objVpss.fvidDisplayCtrl,
        IOCTL_VPS_DCTRL_SET_VENC_CLK_SRC,
        &clkSrc,
        NULL);
    UTILS_assert(retVal == FVID2_SOK);
    /* Set the Clock source for on-chip HDMI */
    clkSrc.venc = VPS_DC_VENC_HDMI;
    clkSrc.clkSrc = VPS_DC_CLKSRC_VENCD_DIV2_DIFF;
    retVal = FVID2_control(
        gSystem_objVpss.fvidDisplayCtrl,
        IOCTL_VPS_DCTRL_SET_VENC_CLK_SRC,
        &clkSrc,
        NULL);

      Sometimes it can get the correct display and sometimes it is not correct at evey time of power up.

      It looks like  the data and clock can not sync.

      Can you give me some hint for this issue?

      Thanks very much.

 Best Regards,

 ST
