RK3568开发板安卓系统之驱动调试（四）-rk3328开发板

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VCC1VCC5V0_SYSVCC2VCC5V0_SYSVCC3VCC5V0_SYSVCC4VCC5V0_SYSVCC5VCC3V3_SYSVCC6VCC3V3_SYSVCC7VCC3V3_SYSVCC8VCC3V3_SYSVCC9VCC3V3_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
