> Hello,

> I'm using the BeagleBone Black's GPIOs to drive some outputs.
> I'm running Kernel 3.8, so I used the Device Tree to configure the GPIOs.
> The cape is loaded during boot via the capemgr.
> But until the BBB has fully booted, some of the GPIOs are set to high.
> Is there a way to prevent this?
