Why does not COMPONENT output work in DM6446?

Hello.

I set :

davinci_enc_mngr.ch0_output=COMPONENT davinci_enc_mngr.ch0_mode=NTSC

into bootargs, connect component cable to DM6446 according to Getting Started Guide and to component input on my TV. When I launching application nothing is showing on TV screen. But DM6446 COMPOSITE output is working fine and TV COMPONENT input is working fine. What's wrong I made?

Thank you.

    Hi,

    By "not working", are you able to check whether there is "no sync", or you see black screen? Some of the TVs can display the infomration I was asking for. What kind of application were you running, some DVSDK apps?

    You might find the doc below helpful:

    Driver data can be found in the PSP docs directory provided with the DVSDK install.
