Disabling USB, bluetooth, HDMI and audio out using overlays

[Sunil Urs]

Hi,

I am new to development on Orange Pi and as such new to the concept of overlays. For the application I want to run on Orange Pi, I need to disable all USB ports (host an OTG), bluetooth, HDMI and audio out. Is there a way to do it using  overlays? Or can I use sunxi-pio utility for the same?

 

I am using nightlu build of Debian Jessie with kernel 4.10.3

 

Appreciate any help.
