但从你发的日志上看3002 media_service服务确实没有 行 292: 08-05 17:00:32.359 529 529 E C01810/SA_CLIENT: GetSystemAbilityWrapper SA:3002 didn't start.

看日志 无法播放 是media_service服务都没有启动

通过Hilog，发现是多媒体播放失败，通过串口日志发现1是bootanimation的状态有ready和finish，但中间缺少bootanimation.started这个状态；2是定位在rkvdec，mpp在做虚拟地址映射的时候，产生一个中断，是关于页面读操作错误的。 我怀疑是因为我用了lpddr4x，而我的设备树和OHOS原生的设备树又不同（rk3568.dtsi、rk3568-dram-default-timing.dtsi、rk3568-linux.dtsi、rk3568-pinctrl.dtsi、rockchip-pinconf.dtsi均不同），但又沿用了OHOS的驱动，所以造成一些底层驱动的问题。但如果沿用OHOS原生的设备树，仅更换厂家板子外设接口的设备树，又完全不能开机。还请看看我的日志，我也不知道分析得对不对。
