楼主
自己修改了rk3399-firefly-aio-lvds.dts文件，
ubuntu编译流程如下：
./build.sh aio-3399j-lvds-ubuntu.mk
./build.sh
编译信息如下：
TARGET_ARCH=arm64
TARGET_PLATFORM=rk3399
TARGET_UBOOT_CONFIG=firefly-rk3399
TARGET_SPL_CONFIG=
TARGET_KERNEL_CONFIG=firefly_linux_defconfig
TARGET_KERNEL_DTS=rk3399-firefly-aio-lvds
TARGET_TOOLCHAIN_CONFIG=
TARGET_BUILDROOT_CONFIG=
TARGET_RECOVERY_CONFIG=
TARGET_PCBA_CONFIG=rockchip_rk3399_pcba
TARGET_RAMBOOT_CONFIG=
编译出文件 AIO-3399J-LVDS-UBUNTU-18.04-GPT-20220217-1450.img，使用烧写工具烧录之后lvds屏幕有白色竖线，不显示桌面；
buildroot编译流程如下：
./build.sh aio-3399j-lvds-buildroot.mk
./build.sh
编译信息如下：
TARGET_ARCH=arm64
TARGET_PLATFORM=rk3399
TARGET_UBOOT_CONFIG=firefly-rk3399
TARGET_SPL_CONFIG=
TARGET_KERNEL_CONFIG=firefly_linux_defconfig
TARGET_KERNEL_DTS=rk3399-firefly-aio-lvds
TARGET_TOOLCHAIN_CONFIG=
TARGET_BUILDROOT_CONFIG=rockchip_rk3399
TARGET_RECOVERY_CONFIG=rockchip_rk3399_recovery
TARGET_PCBA_CONFIG=rockchip_rk3399_pcba
TARGET_RAMBOOT_CONFIG=
编译出文件 AIO-3399J-LVDS-BUILDROOT-GPT-20220216-1751.img，使用烧写工具烧录之后lvds屏幕可以正常显示；
两种编译方式都是在同一个环境下，也没有更改任何东西；
如果先烧写ubuntu的镜像，然后使用下载镜像功能单独烧写buildroot的boot.img的话系统也可以正常启动，但是屏幕还是不亮，设备树和内核不应该只包含在boot.img中吗？
![]()
由于一些原因需要使用ubuntu系统，这种情况如何排查呢，排查了几天毫无头绪，使用dtc工具反编译两个系统的 /sys/firmware/fdt 文件除了memreserve不太一样，其余都是一样的，所以可能是什么问题导致的？
