RK3399配置eDP后系统启动过程中崩溃请问应该如何排查

问题描述及复现步骤:

使用的core-rk3399-jd4核心板 + AIO载板，因为要使用eDP显示屏，修改了rk3399-firefly-aiojd4.dtsi。

但是修改后，系统在启动过程中会崩溃，请问应该如何排查？？？？

使用硬件如图所示

rk3399-firefly-aiojd4.dtsi文件内容如下：

/dts-v1/;

#include "rk3399-firefly-port.dtsi"

panel dts配置有问题，SDK中应该有edp相关dts配置，可以参考配置

谢谢回复。确实是panel的问题，panel部分注释掉，系统就可以正常启动。
但是参照SDK中的rk3399-firefly-edp.dts修改，还有同样的问题。
rk3399-firefly-edp.dts是这样的
