When I power on my customed carrier board, I found my some GPIOS（B22 GPIO13_BT_WAKE_AP） in an uncertain state, It’s about 0.52V.
And when i start ok and load my gpio drivers, it goes OK and return to 0V.
Is this a correct state? Have a hardware design problem?
And when i turn on my customed carrier board, some leds and buzzer will lost control untill load my gpio drivers.
Uboot config could fix it?
