TI 814X display HDMI & VGA problem

Hi , Hardik Shah

I've tried many times but it cannot work!!  I want it to work on TI814X  in version "DVRRDK_02.80.00.10"!  Here is my usecase:

it will show error  below:

thanks a lots

Hi Shah,

I'm trying to develop bootlogo on CVBS output on DM8148 Evm.  I followed what we did on 8168 which let the HDMI & VGA(DVO2) share the GRPX2, but what I find is that the screens always scroll, both on CVBS and HDMI outputs.     Then I changed to GPRX1, it makes no difference.   I guess CVBS and HDMI comp has conflict. but I can't find it.

Can you give some advice?

Thanks,

Eason

Hi,

Same GRPX pipeline cannot be shared on CVBS and HDMI output, but HDMI and VGA(DVO2) can share the same GRPX pipeline.  So the only solution is to use different GRPX pipeline for CVBS and HDMI and provide the same contents.

Thanks,

Brijesh Jadav

Hi Jadav,

Can you tell me where can I find an example of configuring the descripor and list on VPDMA?  Becasue I met some difficulties to make the other GRPX work.

my questios are:

1. Can 2 GPRXs's image source the same one? will there be conflict?

2. Can 2 GPRXs'  configuration descriptor's payload point to the same adderess?

3. Is this right : 1 transport descriptoer is 1 frame. so If I want to send image from VPDMA to  GRPX0 and 1, I need to create the list of data transfer descriptors like this:

GPRX0   1 frame, 

GPRX1  1 frame, 

GPRX0   1 frame, 

GPRX1   1 frame ......................

Is that right?

Thanks very much,

Eason

Hi,

Please contact your local FAE to get the VPDMA spesc..

Below are the answers to your questions.

1, yes, there is not problem as long as you change the buffer pointers as per display fps of the corresponding display.

2, yes

3, yes, what you have to do is you create two sets of transport descriptors, one for each display.

Thanks,

hi, Hardik Shah

How to do so that TI814x can show different images  through HDMI  and DVO2?  

best regards

thanks  

Hi,

If this query is regarding DVR RDK, please contact your local FAE.DVR RDK supports two different contents on two different displays.
