问题描述及复现步骤:
- 固件类型:自行编译的固件
- SDK包名称:rk356x_linux_release_20211019
- SDK更新到哪个COMMIT:0000-00-00 00:00:00
- SDK修改内容:适配EDP屏,尝试了各种组合,只有HDMI和EDP同时插入才能显示,其他方式EDP屏不点亮和显示,修改rk3568-firefly-aioj-edp-M156X40.dts如下
- 1.EDP主/HDMI副可以正常显示(HDMI和EDP都要接入,不接HDMI屏EDP屏也不亮)
- &edp_phy { status = "okay";};
&route_edp { status = "okay"; connect = <&vp0_out_edp>;};
&edp_in_vp0 { status = "okay";};
&edp_in_vp1 { status = "okay";};
- 2.EDP主无显示,HDMI只显示副屏内容
- &edp_phy { status = "okay";};
&route_edp { status = "okay"; connect = <&vp0_out_edp>;};
&edp_in_vp0 { status = "okay";};
&edp_in_vp1 { status = "disabled";};
- 3.EDP无显
- &edp_phy { status = "okay";};
&route_edp { status = "okay"; connect = <&vp0_out_edp>;};
&edp_in_vp0 { status = "okay";};
&edp_in_vp1 { status = "disabled";};
&hdmi { status = "disabled";};
