DVI / HDMI

How to use the HDMI/DVI output of the APF27DevFull and APF51Dev development boards.

Driver installation

Nothing has to be done for the APF51Dev.

For the APF27DevFull:

• Starting from armadeus-3.2 release or in recent GIT checkout, the needed driver is now installed by default. So the following is only kept here for information.

 $ make linux26-menuconfig

Device Drivers--->
    Multimedia devices ---> 
        <*> Video For Linux
        [ ] Enable Video For Linux API 1
        < > DVB for Linux
            *** Multimedia drivers ***
        [ ] Load and attach frontend ...
        [ ] Customize analog and hybrid ...
        [*] Video capture adapters --->
            [ ] Autoselect pertinent encoders/decoders ...
                    Encoders/decoders and other helper chips  --->
                        <M> Analog Devices AD9889 digital video encoders (NEW)   
            [ ] V4L USB devices
        [ ] Radio adapters

 $ make 

Update the APF27 board with the new Linux kernel and rootfs.

Usage

• For the APF27DevFull load the module:

modprobe ad9889

• For the APF51Dev start the utility:

tfp410ctrl -i

Quick DVI test

Connect a HDMI to DVI cable between the APF27DevFull board and a PC monitor with a DVI input. The Linux console must appear on the monitor (640x480 display).

Quick HDMI test

HDMI support has not been tested yet.
