变成了这样了,

这种孔板子中间出线, 想修估计都修不好了。

I2C0_SCL, I2C0_SDA (PB6, PB7)彻底阵亡了

这样怼上去之后, 触摸屏是使用是 I2C1 (PE21, PE22) 了。

接下来修改设备树:

sun8i-v3s.dtsi

i2c1_pins: i2c1 {
        pins = "PE21", "PE22";
        function = "i2c1";
};


i2c1: i2c@01c2b000 {
        compatible = "allwinner,sun6i-a31-i2c";
        reg = <0x01c2b000 0x400>;
        interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
        clocks = <&ccu CLK_BUS_I2C1>;
        resets = <&ccu RST_BUS_I2C1>;
        pinctrl-names = "default";
        pinctrl-0 = <&i2c1_pins>;
        status = "disabled";
        #address-cells = <1>;
        #size-cells = <0>;
};









arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts

&i2c1 {
        status = "okay";


        ft6x06@38 {
                compatible = "focaltech,ft6236";
                reg = <0x38>;
                interrupt-parent = <&pio>;
                interrupts = <1 4 IRQ_TYPE_EDGE_FALLING>;
                reset-gpios = <&pio 4 23 GPIO_ACTIVE_LOW>;
                touchscreen-size-x = <480>;
                touchscreen-size-y = <854>;
                touchscreen-inverted-x;
                touchscreen-swapped-x-y;
        };

};




驱动配置开启:

CONFIG_TOUCHSCREEN_EDT_FT5X06=y
