lctech pi F1C200S u-boot RGB 屏幕正常显示，但Linux 6.8主线内核无法显示
屏幕现象如下：
视频中u-boot可以成功显示，但linux阶段屏幕会变白，然后慢慢变黑。
u-boot编译时把
LCD panel timing details设置为
x:800,y:480,depth:18,pclk_khz:33000,le:87,ri:40,up:31,lo:13,hs:1,vs:1,sync:3,vmode:0LCD panel backlight pwm pin设置为PE6
linux部分按照
按照CSDN上【f1c200s/f1c100s】RGB接口 LCD驱动适配
在suniv-f1c100s.dtsi的pio: pinctrl@1c20800中添加了
lcd_rgb666_pins: lcd-rgb666-pins {
pins = "PD0", "PD1", "PD2", "PD3", "PD4",
"PD5", "PD6", "PD7", "PD8", "PD9",
"PD10", "PD11", "PD12", "PD13", "PD14",
"PD15", "PD16", "PD17", "PD18", "PD19",
"PD20", "PD21";
function = "lcd";
};在suniv-f1c200s-lctech-pi.dts中添加了panel的定义
panel: panel {
compatible = "alientek,alientek_7_inch", "simple-panel";
#address-cells = <1>;
#size-cells = <0>;
#enable-gpios = <&pio 4 6 GPIO_ACTIVE_HIGH>;
reset-gpios = <&pio 4 4 GPIO_ACTIVE_LOW>
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
panel_input: endpoint@0 {
reg = <0>;
remote-endpoint = <&tcon0_out_lcd>;
};
};
};在panel-simple.c中添加了alientek参数的定义。
但修改前后现象都是u-boot可以成功显示，但linux阶段屏幕会变白，然后慢慢变黑。。
尝试修改成panel-simple中其它屏幕的型号也不行。
linux系统下也没有/dev/fb0这个设备文件。
最后附上启动log，恳请诸位帮忙分析一下问题的原因。

是主线内核吗？修改过设备树以及simple-panel.c代码吗？

我当前的bootargs就是 console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw 把console=ttyS0改为tty0后串口没输出了，应该不是要改为tty0。。

看晕哥回过的帖子，屏幕驱动有FB和DRM的区别，或许我的屏幕是DRM驱动？

没有fb0，那估计驱动还没对，我也是刚用，下载的是Nano的内核`https://gitee.com/LicheePiNano/Linux.git`
里面设备树的panel节点是这样的
```code
panel: panel {
compatible = "qiaodian,qd43003c0-40", "simple-panel";
#address-cells = <1>;
#size-cells = <0>;
enable-gpios = <&pio 4 6 GPIO_ACTIVE_HIGH>;
port@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
panel_input: endpoint@0 {
reg = <0>;
remote-endpoint = <&tcon0_out_lcd>;
};
};
};
```
code
`menuconfig`里面也要相应配置Device Driver下的LCD作为Console

可以设置成console=tty0 console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw
这样可以串口和屏幕都有输出

这是我注释掉的，因为我看网上的教程，这一行有的是enable gpio 有的是reset gpio。
以前试过注释掉其中一行，屏幕还是同样的现象。
刚才试了把两行都取消注释，屏幕也还是同样的现象，感觉问题不是在这附近。

Re: lctech pi F1C200S u-boot RGB 屏幕正常显示，但Linux 6.8主线内核无法显示
今天又按照这位博主的方法用linux 6.4.11从头到尾修改了一遍 。
不过因为我的屏幕是800x480的屏幕，所以屏幕型号从ampire,am-480272h3tmqw-t01h改成了urt,umsh-8596md-t
但屏幕还是没显示。。

@domng
设备树文件是用#注释的吗？我记得是/**/啊。
