固件类型：官方提供的固件
固件文件名称：rk356x_linux_release_20211019
固件下载地址：百度网盘
Log日志：log.txt

修改vi device/rockchip/.BoardConfig.mk
改成
#!/bin/bash
CMD=realpath $BASH_SOURCE
CUR_DIR=dirname $CMD
source $CUR_DIR/firefly-rk3568-buildroot.mk
# Kernel dts
#export RK_KERNEL_DTS=rk3568-firefly-aioj
export RK_KERNEL_DTS=rk3568-firefly-aioj-edp-M156X40

# PRODUCT MODEL
export RK_PRODUCT_MODEL=AIO_3568J
重新编译build.sh，编译后有rk3568-firefly-aioj-edp-M156X40.dtb
烧写入板子，EDP无输出，/dev/目录下也没有FB的设备节点，DTS只修改了屏幕Timing，其他没有修改，DTS修改如下：
display-timings {
native-mode = <&timing0>;

            timing0: timing0 {
                    clock-frequency = <138780000>;
                    hactive = <1920>;
                    vactive = <1080>;
                    hfront-porch = <100>;
                    hsync-len = <20>;
                    hback-porch = <210>;
                    vfront-porch = <12>;
                    vsync-len = <3>;
                    vback-porch = <36>;
                    hsync-active = <0>;
                    vsync-active = <0>;
                    de-active = <0>;
                    pixelclk-active = <0>;
            };
    };

目前遇到另一个问题，屏幕在SD卡固件是点亮了，但是烧写到EMMC依然无法点亮，SD卡里uboot的部分log如下：
Rockchip UBOOT DRM driver version: v1.0.1
VOP have 1 active VP
vp0 have layer nr:6[0 2 4 1 3 5 ], primary plane: 4
vp1 have layer nr:0, primary plane: 0
vp2 have layer nr:0, primary plane: 0
Using display timing dts
edp@fe0c0000: detailed mode clock 138780 kHz, flags[a]
H: 1920 2020 2040 2250
V: 1080 1092 1095 1131
bus_format: 100e
VOP update mode to: 1920x1080p0, type: eDP0 for VP0
VOP VP0 enable Smart0[500x501->500x501@710x289] fmt[2] addr[0x7df20000]
Link Training success!

烧写到EMMC后，uboot的log如下：
Rockchip UBOOT DRM driver version: v1.0.1
VOP have 1 active VP
vp0 have layer nr:6[0 2 4 1 3 5 ], primary plane: 4
vp1 have layer nr:0, primary plane: 0
vp2 have layer nr:0, primary plane: 0

请问问题是怎么解决的？

我现在 cat /sys/kernel/debug/dri/0/summary

显示VOP1已经打开EDP了 但是屏幕完全黑的
