AIO3399J无法点亮LVDS屏幕
使用SDK包编译固件，参考官方文档：https://wiki.t-firefly.com/zh_CN/AIO-3399J/driver_lcd.html根据步骤配置，但是在u-boot里面找不到rockchip-dw-mipi-dsi.c的文件。
升级完成之后，只有背光亮，屏幕显示黑屏。
有dts有根据链接上面说的配了。 abcxyztt 发表于 2022-10-24 11:16
dts没有配置吧
有的，dts在楼下。 本帖最后由 aibou 于 2022-10-26 15:36 编辑

应该是dts配置不对
dts文件如下所示，可以帮忙看看哪里有问题吗？目前是板子上看DSI的接口有出来，背光也可以开关，就是没信号。
