Somebody can tell me if there is some kind of "level" at boot, which Pcduino manages its pins status?

I'm using a Pcduino2 to build a surveillance robot. Even modifying the script.bin (fex file, at sdcard boot folder) to attach PWM and GPIOs to logic level 0, the port PB02 (PWM0 - GPIO5) keeps at high level at boot, for some time. After some time, it seems like the system reads the fex file configuration and attach level logic 0 to this pin, before boot the system completely.


Anyone knows something related to this behavior?
