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

Driver installation

APF51Dev

  • Nothing has to be done

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 your APF27 board with the new Linux kernel and rootfs.

Usage

APF27DevFull

  • Load the module:
# modprobe ad9889

APF51Dev

  • Start the utility:
tfp410ctrl

Then press 'Q' to exit

Quick DVI test

Connect a HDMI<->DVI cable between the APFxxDev board and a PC monitor with a DVI input or use a HDMI<->HDMI cable if your display has this kind of refinement. The Linux console must appear on the monitor.
