About DM355

Dear everyone:

I am a new comer to davinci, a few days ago, I bought a DM355 EVM, I want to capture image from Cmos or PAL,and output the image to LCD or TV OUT. Now I don't know how to switch the input and output. From <DaVinci Linux CCDC Driver User's Guide.pdf>, I found we can switch input between SVideo and LCD by setting  device_type value in the bootargs, In default setting , runing DirectShow Demo , I can see that the  PAL  image is send to the TV monitor. So I changed the device_type value to 0, the input should be MT9T001, I can't connect any CMOS sensors, only the PAL Video ,  run Directshow demo, but the TV Moitor can see the input PAL video.that is, device_type  is not used to switch input.

else, How to switch output between LCD and TV OUT, from <DaVinci Linux Video Sysfs.pdf>,the" /sys/class/davinci_display/ch0/output" attribute define the display show, but I  can find the " /sys/class/davinci_display/ch0/output" in Linux.

How can I do, Please help me!

thanks

    It was my understanding that device_type controlled the video input (I have used this before to connect DM355 EVM to Leopard Imaging sensor card) and davinci_enc_mngr.ch0_output to select video output mode.  If you continue to have issues, you can post your u-boot variables and perhaps a log of your boot and we can try to investigate further.
