it will take about 25uA~ 28uA.
when I remove R18 R19, set io to input with pullup, it will take about 10uA,
&button1 {
gpios = <&gpio0 5 (GPIO_ACTIVE_LOW|GPIO_PULL_UP)>;
};
&button2 {
gpios = <&gpio1 9 (GPIO_ACTIVE_LOW|GPIO_PULL_UP)>;
};
this spi flash I have used in Other hardware，it take 4uA， used P0.24->MISO P1.00->CS P0.20->CLK P0.22->MOSI. I do not know why it High power consumption.
