YPbPr(1920x1080i @60fps) output problem on DM368 IPNC

Try VIDWINMD (0x01c71e04) = 0x00000101 instead.  It looks like you have VHZ1 (Video window 1 horizontal zoom) enabled to x2 mode.

Thanks for the quick response.

Maybe you mean VIDWINMD at 0x01c71c04 not 0x01c71e04

In my case VIDWINMD = 0x303, your suggestion : 0x101

Bit 1: VFF0, Bit9 : VFF1 is for setting video window mode(Frame mode or Field mode)

so, it's not related to this issue.

Thanks anyway.

Hennessy,

I have one question.

In your application, is it only 'displaying' or even 'capturing'(loopback) is done?

~Nag

Dear Nagabhushana.

I already did "capturing and displaying" but 'displaying' has problem like my explanation.

But now the problem is fixed.

The problem is the OSD_CLK0 and OSD_CLK1 in VENC register block.

OSD_CLK0 : 0 and OSD_CLK1 = 1 is the correct setting for 1080i @60fps

Thanks for helping.

Dear Hennessy,

I write a scrip to try to enable component output on 1080I60 mode. But I only see the garbage on LCD monitor. If I set VENC_VDPRO to enable color bar, the color bar is no problem. I also check OSD_CLK0/1 that you mention that the value is 0 and 1. What's your PLL2 setting? I can not get 74.25MHz(PLL2->PLLDIV5) when use ARM : 432MHz. The divider just gets the 72MHz for VENC clock. Can you please give me more hints on this portion? Thanks a lot.

Dear Hennessy,

Thank you so much for your inputs.

I have another queries want to consult with you.

1. How do I make sure my output frame buffer address is in SDRAM? Do you know the default address in the DM368IPNC code base?

2. Are the calculations as below right?  

    OSD_VIDWIN0OFST = 0x1000 | (1920 >> 4);
    OSD_VIDWINADH = ((tmp_addr >> 16) & 0xFFFF); // SDRAM start address higher 7bits
    OSD_VIDWIN0ADL= tmp_addr & 0xFFFF; // VIDWIN0ADL SDRAM start address low 16bits

    OSD_VIDWIN1ADL // Does this register need to fill out? But I do not know what the calculation is.

Dear Hennessy,

Let me summarize my situation.

I still can not bring up 1080I OSD setting when enable component output. Evenif I modify kernel/media/video/davinci/vpbe_osd.c.

Can you please give me more lights on this portion?

Thanks a lot.
