Hi,
i have circuits which are powered using transistors conected to gpio. when i connect the power to the OPI Zero using the micro usb, while the OPI Zero is booting some GPIO change their state to High, and i only can set to low running some script or using the console. My problem is that the board is turning on devices before my script start.
That's why i want to set all the gpio ports to low in boot.
Ty,
EDIT: im using ARMBIAN 5.60 stable Ubuntu 16.04.5 LTS 3.4.113-sun8i
