屏幕是在IMX8mp上点亮过的,初始化timing序列是没问题的,一般但是IMX93就是不亮桌面不知道是什么情况,希望给个建议。
ps:感觉整个时钟都不对的,音频和LVDS的时钟频率是试出来的,而不是硬件数据算出来的。
Solved! Go to Solution.
已解决!pixeclock问题!!!!
把IMX93的设备树的LVDS的ldb_phy关闭了。
&ldb_phy {
status = "disabled";
};
已经调试这个屏幕2周了,希望有人可以回复一下。
Hello,
If the display works on MX8MP then copy the dtb in the MX93, the clock and the output should be the same.
