一 先来看下 qnx和bsp的分析
2024-08-02 08:20:09.967 0 0 W : set ivi0_backlight_en 1 //中控开启背光
2024-08-02 08:20:09.967 0 0 W : set ivi1_backlight_en 1 //副驾开启背光
分析最后一次拍照时间 ON_点火_15s_20240802082006.jpg 拍照的时候 背光还没有拉起来
qnx log 开启背光 Aug 02 08:20:09.906

二 来看fwk层分析
android.hardware.graphics.composer服务crash导致后续的surfaceflinger, zygote, system_server进程重启

执行hal层的compose指令失败了,发现这里出现了tombstone了

三 问题确认转给高通分析更新相应的so库 问题解决
