That is the default GPIO pin state of the chip on power on i.e.As per https://www.raspberrypi.com/documentati ... io-control
if we edit config.txt we can change that e.g. for GPIO8 On reboot we now see You might want to do it differently depending on wha thardware you have attached e.g. pull down resistors, power up the peripheral later etc.
Code:
pi@pi:~ $ pinctrl get 2,3,4,8,7,1,0,5,6 0: ip -- | hi // ID_SDA/GPIO0 = input 1: ip -- | hi // ID_SCL/GPIO1 = input 2: ip -- | hi // GPIO2 = input 3: ip -- | hi // GPIO3 = input 4: ip -- | hi // GPIO4 = input 5: ip -- | hi // GPIO5 = input 6: ip -- | hi // GPIO6 = input 7: ip -- | hi // GPIO7 = input 8: ip -- | hi // GPIO8 = inputif we edit config.txt we can change that e.g. for GPIO8
