Re: 有没有“”设备树, Linux“”配置说明

看起来是V3s吧,
版本是多少,有没有改过设备树?
现在显示屏没有显示?

Re: 有没有“”设备树, Linux“”配置说明

你试一试改过 sun8i-v3s.dtsi 文件 里面的:

pio: pinctrl@01c20800 {
            compatible = "allwinner,sun8i-v3s-pinctrl";
            reg = <0x01c20800 0x400>;
            interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>,
                     <GIC_SPI 17 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&ccu CLK_BUS_PIO>, <&osc24M>, <&osc32k>;
            clock-names = "apb", "hosc", "losc";
            gpio-controller;
            #gpio-cells = <3>;
            interrupt-controller;
            #interrupt-cells = <3>;
....

而我用的是这个dts:
https://github.com/Lichee-Pi/linux/blob/zero-4.13.y/arch/arm/boot/dts/sun8i-v3s-licheepi-zero-with-800x480-lcd.dts

然后我改用这个dts:
https://github.com/Lichee-Pi/linux/blob/zero-4.13.y/arch/arm/boot/dts/sun8i-v3s-licheepi-zero-dock.dts

就可以了,

估计是这个:

&panel {
	compatible = "urt,umsh-8596md-t", "simple-panel";
};

会去初始化panel那组引脚,而没有找到定义.

我用的480*272的屏幕,应该理论上uboot更换一下,设备树更换一下就可以了吧?

Re: 有没有“”设备树, Linux“”配置说明

@john78
原因是pinctrl驱动中对pe引脚定义的lcd功能名称和设备树中的不一致导致的,只需要将设备树做如下修改就好了

			lcd_rgb666_pins_a: lcd-rgb666-pe {
				pins = "PE0", "PE1", "PE2", "PE3", "PE4", "PE5",
				       "PE6", "PE7", "PE8", "PE9", "PE10", "PE11",
				       "PE12", "PE13", "PE14", "PE15", "PE16", "PE17",
				       "PE18", "PE19", "PE23", "PE24";
				function = "lcd";   /*licheepi 4.13y版本的设备树此处为function = "lcd0", 但是驱动中是 "lcd"*/
			};


即:function = "lcd0"; -> function = "lcd";

如果使用sun8i-v3s-licheepi-zero-dock.dts,就完全不能驱动屏幕
