core-rk3399-jd4配置LVDS屏，显示不正常，请问如何设置？

diyin · September 19, 2022, 9:44am

固件类型：自行编译的固件
SDK包名称：rk3399_linux_release_v2.5.1_20210301_firefly_split
SDK修改内容：设备树中增加dsi节点
Log日志：日志.zip

在设备树中增加了dsi节点和TC358775G的panel-init-sequence后，LVDS屏可以点亮，但是显示不正确（如图所示）。
怀疑是按照TC358764_5_774_5XBG_DSI-LVDS_Tv11p_nm表格生成的panel-init-sequence不对，
以下是屏的参数和我的配置，请专家大神帮忙看下，是否有哪里配置错了？
