Disable HDMI Pine64

[martinayotte]

but not turning off backlight

According to Pinebook schematic, the LCD power is controlled by GPIO PH6, so you can turn it off using :

Code:

echo 230 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio230/direction
echo 0 > /sys/class/gpio/gpio230/value

and you can turn it on again with :

Code:

echo 1 > /sys/class/gpio/gpio230/value

EDIT : Ouupps !!! I didn't read the title properly, you were talking about HDMI on Pine64, while my reply is about Pinebook LCD ... Sorry !
