RK3568 Android11 EDP不显示问题

passby

使用官方SDK   Firefly-RK356X_Android11.0_git_20210824   


修改 device/rockchip/rk356x/BoardConfig.mk
#PRODUCT_KERNEL_DTS ?= rk3568-evb1-ddr4-v10
PRODUCT_KERNEL_DTS ?= rk3568-firefly-aioj-edp_M156X40

修改  rk3568-firefly-aioj-edp_M156X40.dtsi

&edp_phy {
    status = "okay";
};

&route_edp {
    status = "okay";
    /*GP Debug xcx*/
    connect = <&vp1_out_edp>; //add by xcx
};

&edp_in_vp0 {
    //status = "okay";
    status = "disable";
};

&edp_in_vp1 {
    //status = "disable";
    status = "okay";

};

使用  ./FFTools/make.sh -d rk3568-firefly-aioj-edp_M156X40 -j12 -l rk3568_firefly_aioj-userdebug 命令编译后，烧录到开发板，hdmi屏幕正常显示，EDP屏幕全程无输出，

使用

  cat /sys/kernel/debug/dri/0/summary

请问还有哪里可能有问题？

1.  背光是否有亮
2.  dts 仅供参考， 时序和屏参也会影响显示，要根据屏幕规格书更改
3. disable 改成disabled

1. &edp_in_vp0 {
   
2.     //status = "okay";
   
3.     status = "disable"; ----->disabled
   
4. };

1. 背光不亮
2. 修改后还是没反应

一般供电正常的话，就算没有显示，屏幕的背光也会亮的，如果连背光都没亮，检查下屏幕供电、背光供电以及pwm是否正常

更新了最新的SDK后解决了

原来的sdk是网盘下的   21年8月的   可能后续有过更新
