DVI / HDMI

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. Informations are kept here as reference.

Usage

APF27DevFull

• Load the module:

# modprobe ad9889

• By default 640x480 resolution will be used to drive the HDMI/DVI monitor.

APF51Dev

• Start the utility:

tfp410ctrl

• By default LW700 LCD resolution (800x480) will be used to drive the HDMI/DVI monitor. If your monitor doesn't support it, then you can use tfp410ctrl to find the best suiting resolution: press 'e' in main menu. It will read and show you the EDID infos from your monitor and tell you which standard modes are supported. Then it's up to you to use fbset to change framebuffer characteristics.
• Press 'Q' to exit tfp410ctrl

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.
