When booting an Orange Pi the default pin state seems to be HIGH.
Is there a document that I can edit that will change their default state to LOW?
There is a post in the Raspberry PI page which details the process. I know this is a different device, but it should help: https://www.raspberrypi.org/documentation/configuration/pin-configuration.md
EDIT:
According to this link, there is an utility called "generich3/GPIO" to perform that task.
bootcode.bin, dt-blob.bin, and config.txt in the file system.
WiringOp Github page yesterday.
