ROC-RK3855S-PC 操作拓展排针GPIO没有反应，请问如何处理？

我根据官方提供的排针定义图，做了一个扩展板，用来控制三路继电器，分别用的GPIO1_D0,GPIO1_D1,GPIO1_D2,其中D0,D1上电就输出高电平，改变io方向也一样无法控制
echo 56 > /sys/class/gpio/export
echo 57 > /sys/class/gpio/export
echo 58 > /sys/class/gpio/export

echo "out" /sys/class/gpio/gpio56/direction
echo "out" /sys/class/gpio/gpio57/direction
echo "out" /sys/class/gpio/gpio58/direction

echo 0 /sys/class/gpio/gpio56/value
echo 1 /sys/class/gpio/gpio56/value

echo 0 /sys/class/gpio/gpio57/value
echo 1 /sys/class/gpio/gpio57/value

echo 0 /sys/class/gpio/gpio58/value
echo 1 /sys/class/gpio/gpio58/value


ls /sys/class/gpio/gpio58
cat /sys/class/gpio/gpio58/direction
cat /sys/class/gpio/gpio58/value

可能需要确认一下内核dts里复用等情况
