Audio and video on the Cubox - J.F. Moine - October 24, 2014

This directory contains the required stuff to have audio and video on the Cubox with a kernel 3.18 (no acceleration yet).

Kernel

Boot

The u-boot "boot.scr" script must have a bootargs as:
	console=ttyS0,115200n8 console=tty1,115200 root=/dev/sda2 rootwait video=HDMI-A-1:1920x1080-32@60
(the most important is the video= parameter)

X11

You must use the standard xorg "modesetting" video driver (not 'fbdev').
Here is a copy of my xorg.conf to copy in /etc/X11/.
Mainly, it would have: Note: "modesetting" does not work anymore with my Debian sid.
You may use the driver myms_drv.so (MY ModeSetting) which has support for video overlay (the source is here).
xorg.conf must contain:
	Driver	"myms"
	Option	"kmsdev" "/dev/dri/card0"
	Option	"ShadowFB" "false"
	Option	"SWcursor" "false"
	Option	"Monitor-HDMI-0" "monitor"
