Hello!

I build an own cap with relays.
Now I have on "gpio10" (P8_31) an devicetree overlay with direction out.

When the BBB are booting, I have on this pin 2.78V ... after some seconds, 
he load my device tree(?) and all outputs are for 1 sec on and then off. 
After this, "gpio10" has 0V and it is output.

So my question:
How can I set the devicetree for GPIO at boot time? When "gpio10" is 
connected to my relay, the LED of my relay are glimming and the BBB doesn´t 
boot.

Or can I disable all gpio at boot time and enable it after he load my 
devicetree?

Thank you!
