core-rk3399-jd4核心板配置eDP后，系统启动过程中崩溃，请问应该如何正确配置eDP屏？

diyin · 发表于 2022-8-16 17:03:27

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？？？？

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

panel 的dts配置参考这份改

参照你的代码，系统可以启动了，屏的背光也亮了，但是显示黑屏，示波器上EDP_TX0N没有信号，我在查查文档。
请问下在我这个板子的原理图上，lcd-en是对应LCD_EN吧，lcd-rst是对应那个引脚？看原理图是不是eDP用不上lcd-rst。

luwy · 发表于 2022-8-18 10:32:01

dts只是参考，实际还是按照原理图来，如果原理图没有就不用配置；可以检查一下vcc供电是否都正常
