家里碗摔了，去某多买碗，发现推送给一个rk3506的板子，60多遂下单，

用关键字搜索找到原理图，发现支持rgb和mipi,问了一下那个屏便宜，ai推荐rgb,看原理图兼容原子rgb屏接口，然后去咸鱼斥巨资80购入一个原子，野火兼容屏，

然后店家说板子没有现货，要延期，过几天之后竟然发顺丰，昨天到了，


接上屏然后花屏，查询一下分辨率，板子是800x400，屏是1024x600,花费一天时间从百度网盘下载SDK，修改rk3506g-mini-v10-rgb.dtsi，display-timings {
            native-mode = <&rgb_timing>;

            rgb_timing: timing0 {
                clock-frequency = <51200000>;
                hactive = <1024>;
                vactive = <600>;
                hback-porch = <160>;
                hfront-porch = <160>;
                vback-porch = <23>;
                vfront-porch = <12>;
                hsync-len = <20>;
                vsync-len = <10>;
                hsync-active = <0>;
                vsync-active = <0>;
                de-active = <0>;
                pixelclk-active = <0>;
            };
        };

修改触摸

        pinctrl-0 = <&gt911_int_pin

不过编译出来boot文件，设备树应该是在这个文件里面，烧写进去，查询分辨率

好像正常了，接入屏幕可以显示了
