Hi, Display type mean pixel format? It's because only one pixel format is supported on dm6467 i.e. YC Planar. So there is no need to change it.
If display type is bt656 or bt1120, it will be selected based on the mode selected. dm6467 supports four boot time arguments ch0_output, ch0_mode, ch1_output and ch1_mode. These are used to set the output physical connection and mode on that connection on a channel.

Is this not working? This is same for DM6446, DM355 & DM6467. Only difference is DM6467 has 2 channels and bootargs can be set for both channels. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Phil Quiney Sent: Tuesday, August 12, 2008 5:56 AM To: Ondrej Pindroch Cc: [email protected] Subject: RE: DVEVM 6467 no signal on output Hi, OK, that is a change over the DM355/6446 then. On these you get to set both the mode & the output with kernel parameters like.. davinci_enc_mngr.ch0_mode=ntsc davinci_enc_mngr.ch0_output=COMPOSITE Here 'mode' can be things like NTSC, PAL, 640x480, 1080P & 'output' can be COMPOSITE, SVIDEO, COMPONENT, LCD... (depending on what hardware you have of course). The defaults are COMPOSITE + NTSC which seemed to be what your kernel was saying on boot up. If you have changed the default by editing code are you actually booting the kernel you changed? I am still suprised there isn't the kernel parameter method of changing the display type/format - is there a TI person that can confirm that editing code is the only way to change this?

I can change sources. But now I have no signal on all outputs. Really funny is that, I have tested the whole DEMO one week ago. It works. Than I was away. Monday I returned to work and I have no signal.

They are harmless - the module has loaded and should still function. I would check your boot arguments - I would have expected a xxxxx=component (where xxxxx is some module parameter or other) in the boot line or is it the default on the 6467 (I don't have a 6467 board to try here)? Just checking your kernel output and it says 'ch0 default output "COMPOSITE", mode "NTSC"' which backs up this idea.
