4 驱动调试

4.1 电源配置

RK GPIO编号说明

A组: A0-A7对应0-7B组: B0-B7对应8-15C组: C0-C7对应16-23D组: D0-D7对应24-31

GPIO编号计算方法:
例如：GPIO4_C4 = 4*32+16+4 = 148

4.1.1 查看原理图

4.1.2 获取需要的配置信息，并在dts里配置

通过查看原理图，获取到相应的信息，然后在dts里配置
1、RK809和TCS4525是挂在I2C0下。输出电压VDD_CPU为0.9V, dts配置如下

    vdd_cpu: tcs4525@1c {
        compatible = "tcs,tcs452x";
        reg = <0x1c>;
        vin-supply = <&vcc5v0_sys>;
        regulator-compatible = "fan53555-reg";
        regulator-name = "vdd_cpu";
        ...
        regulator-init-microvolt = <900000>;
        ...
    };

2、RK809各输入电压的输入源

输入电压	输入源
VCC1	VCC5V0_SYS
VCC2	VCC5V0_SYS
VCC3	VCC5V0_SYS
VCC4	VCC5V0_SYS
VCC5	VCC3V3_SYS
VCC6	VCC3V3_SYS
VCC7	VCC3V3_SYS
VCC8	VCC3V3_SYS
VCC9	VCC3V3_SYS

dts配置如下：

    vcc1-supply = <&vcc5v0_SYS>;
    vcc2-supply = <&vcc5v0_SYS>;
    vcc3-supply = <&vcc5v0_SYS>;
    vcc4-supply = <&vcc5v0_SYS>;
    vcc5-supply = <&vcc3v3_sys>;
    vcc6-supply = <&vcc3v3_sys>;
    vcc7-supply = <&vcc3v3_sys>;
    vcc8-supply = <&vcc3v3_sys>;
    vcc9-supply = <&vcc3v3_sys>;

通过查看原理图，VCC5V0_SYS是底板给的，VCC3V3_SYS是由VCC5V0_SYS转的
3、RK809输出电压名及其电压值

	电源名称	电压值
BUCK1	VDD_LOGIC	0.9V
BUCK2	VDD_GPU	0.9V
BUCK3	VCC_DDR	硬件调节
BUCK4	VDD_NPU	0.9V
LDO1	VDDA0V9_IMAGE	0.9V
LDO2	VDDA_0V9	0.9V
LDO3	VDDA0V9_PMU	0.9V
LDO4	VCCIO_ACODEC	3.3V
LDO5	VCCIO_SD	1.8-3.3V
LDO6	VCC3V3_PMU	3.3V
LDO7	VCCA_1V8	1.8V
LDO8	VCCA1V8_PMU	1.8V
LDO9	VCCA1V8_IMAGE	1.8V
SWCUT1	VCC_3V3	3.3V
