你好：
我使用luckfox lyra plus 驱动树莓派DSI屏幕时遇到这个问题。
uboot阶段显示logo，正常显示OK 。
然后到启动kernel之后就不行，不能显示log文件在屏幕上，
跑 modetest -M rockchip -s 74@71:800x480 是黑屏的。（用的是树莓派DSI屏幕，分辨率是800*480）需要给屏幕重新上电才能显示。
固件用的是SDK 重新编译的。只在buildroot里添加了QT5的支持包。
串口输出如下：

到了这个时候，重新插拔一下屏幕线，就有正常显示了，然后再次输入modetest命令也是能正常显示的。
不知道是哪里设置问题，请大神指教指教，谢谢！！！
使用luckfox lyra plus驱动树莓派DSI屏幕时，uboot阶段显示logo，启动kernel后就不行，需要给屏幕重新上电才能显示。
您好，您遇到的这种情况我们没有遇到过，Uboot 阶段有LOGO显示说明设备树的timing 配置和初始化序列都是正常的，在内核阶段打印dw-mipi-dsi-rockchip ff640000.dsi: failed to find panel or bridge: -517 只是在前几次绑定没有成功，最后有绑定成功也是可以正常运行的。
屏幕重新拔插的话如果是重新上电，那么正常情况下没有初始化序列屏幕应该是没反应的；
如果是仅重新连接信号线就可以显示我怀疑可能是供电问题

那大概率是供电问题了。我用usb供电的 芯片加屏幕应该要拉爆电脑U口了。我试试加个电源上去看看。谢谢大佬！
