DM8107 , problem size display on VOUT0

Hello,

e2e.ti.com/.../224844 or could try to search in e2e for similar issue.

This is that I do !!!
I search similar issue but I dont found it !

As we can see from the recorded signal on the oscilloscope, the image (payload) is not defined on a line but on half.

I tried through a SWMS module and I added the white border.
I see that the image is not cut but resize in width.
The output that I use is the port VOUT0 of the DM8107 and is connected to an ADV7391 component.

The signal is good since recognized by ADV, but the contained is invalid.

My problem is that I can not know if the change ofthe width of the image is made in the hdvpss code or in LinkApi.

What about you?
A little help please !!
Regards

Can you please press 'p' when demo is running? it will print the input and output size for all the links, then you could find out the link creating the problem.
Regards,Brijesh

Hi Brijesh,
Thank you for your response.
I don't use usecase of mcfw demo. I use a custom application.
I don't see in the programs demo (mcfw_demo, link_api_demo and link_api_sd_demo) the 'p' command to print output and input size for the links.
Can you tell me what is the command necessart to obtain this log ?

Regrads

ok, in that case, just check if display is getting half size frame, then debug back from display to check which link is providing half frame.
If the display is getting complete frame with the correct frame size, display is configuration is somewhere wrong, which needs to be fixed in the display firmware..

Hi Brijesh,

If I understand that you say, I should add debug in diplayLink_drv.c (links_m3vpss) .

Can you tell me the functions where it is relevant to add debug and what log ?

Thanks.

Please put break point in DisplayLink_drvHandleDynamicPitchChange
DisplayLink_drvSetResolutionDisplayLink_drvSetFmtand check the input resolution.
Rgds,Brijesh

Thanks,

I do it today and I come back to you.

Regards

Hi Brijesh,
I have add debug in displayLink ( *** DISPLAY).
My usescase is currently : CAPTURE (1x720x576i50) -> DEI -> SWMS -> DISPLAY (1x720x576i50)

I see in the log that I never happens in DisplayLink_drvSetResolution and DisplayLink_drvHandleDynamicPitch functions.

I tried to force the call of the function DisplayLink_drvSetResolution with DISPLAY_LINK_CMD_CHANGE_RESOLUTION system link control, but none of my debug messages appear.

In the log bellow, i don't understand the values of the pitch Y/C input / output. In don't resize the resolution therefore, these values should be identical.

Ca you explain me this difference ?
How is calculated the pitch size ?

This is the log :

Hi Nocolas,

 

Normal print statements does not come here, you need to Vps_printf statement to print the message to get them on the console. Please take the complete log from the start, it will be there once you use Vps_printf statement..

 

 

rgds,

Brijesh

I know it !
It's that I do. I have no more information than what I posted.

Can you explain the pitch values ?

Thanks

ok, actually, there are not registers to check if frame size is configured correctly. Its all programmed in descriptor, from which it is difficult to know the frame size.
Before this, can you dump the value at the offset 0x48100114? I want to check if the clocks are configured correctly in this registers.
Rgds,Brijesh

Hi Brijesh,

In the register 0x48100114, I read the value 0x0009010D.

In the register 0x48100118, I read 0x0000000F.

The HD_VENC_D_register :

0x04810A000 : 0x5420305C

0x04810A028 : 0x842716C0

0x04810A030 : 0x805AA103

0x04810A034 : 0x00000137

0x04810A03C : 0x805A211E

0x04810A040 : 0x00019000

0x04810A044 : 0x00120150

0x04810A048 0x02002120

0x04810A04C : 0x02001142

0x04810A050 :0x0013E13A

0x04810A054 :0x805A2116

0x04810A058 : 0x00018001

0x04810A05C : 0x00120150

0x04810A060 : 0x02001120

0x04810A064 : 0x0200412B

For me, all is correctly configured. The ITU's signals that are produced in DVO2 are good, but, it is the picture payload that is malformed.
In the scope capture, the line duration is 64µs (normal) and the frame duration is 20 ms (720x576i50). All is good at this level.

Where's the reduction factor by 2 ??? I'm searching in the sources code and datasheets, I do not find this information.

Regards

When I reset the bit 16 at 0x048100114, the width seems good, but the video in not correctly displayed.

There is a line dithering problem.

See below :

Regarding the patch you indicate, I based him to realize the change in my environment.

Thanks,
When You say configure the pclk to 27MHz, can you explain where I have to make the change ?

In vpshal_hdvenc.c, I use this configuration :
{FVID2_STD_PAL, 1442, 576, FVID2_SF_INTERLACED, 27000, 25, 24, 134, 128, 2, 20, 2}, 4, 4, 4},
The pclk used is already set to 27MHz... or is not the good.

when I try to use the values that are in the patch
{{FVID2_STD_PAL, 720, 576, FVID2_SF_INTERLACED, 27000, 30, 12, 68, 64, 2, 19, 3}, 4, 4, 4},
the result is not good, the VOUT0 output signals are nor recognize by the video decoder ADV7391, then, the line duration is 32µs and the frame duration is 10 ms !!

Ok Brijesh, it s solved.
I have apply in vpshal_hdvenc.c the values of the patch, and i have manually reset the bit 16 at 0x048100114.
The resolution is good.

Thank you for your patience
Regards

Glad to hear  it started working.

Regards,

Brijesh
