Description

环境信息】EE环境
【问题出现时间】：20230518 8点21分 第148次开机
【前提条件】：车机上电（KL30ON ，KL15 ON，已连接中控和功放，可正常输出声音）
1.5月18日第148次开机晚上20点50左右开始运行monkey测试

2.5月19日早上8点25分发现副屏黑屏（喇叭有副屏的音乐声音输出）

【实际结果】

副屏黑屏，时不时有声音从喇叭输出.(可以通过wifi建立adb连接，且读取monkey进程依然存在)

【期望结果】
副屏正常运行monkey测试，无黑屏或重启等严重异常问题。
【备注】：

车架号VIN：HRYTTESTVINMGM400

副屏log按照monkey日志（V0095）抓取步骤，在11点03分左右开始获取。

其中查看到副屏中还有8点09分的log(不知道为何会有此log，此时monkey还在运行)

log地址：https://ofs.human-horizons.com/#/download/index/bX2erAYZBhI%3D

monkey的log已添加到附件中

1.从日志中发现有下列屏端异常的日志
E DTC_Display: screen not ready(0), bl_sta(119), lvl(0)
2.备份的日志包中，kernel日志打包异常，每个包中都只有000148_kernel_00358_230518_192854.log.ing这一份相同日志
同时logcat目录中的日志是空的

1. log 文件中只的tlog_iov0201017500006162025411a2212290000000911_000148_0519110635.tar.gz -> br文件有logcat的log

2.解压文件后查找Monkey 字样，未到，说明与 上面的描述不付--》5月18日第148次开机晚上20点50左右开始运行monkey测试

怀疑没有抓到现场

■压缩包分析
查看压缩包，从FSEM_000148_0530_0518195559.tar.gz开始tlog进程就已经停了
之前存在过一个问题：当设备存储满了之后tlog还是一直在跑，导致一直在打log报错，最后系统分区增加
https://share.thundersoft.com/redmine/issues/117367
之前的修改方案就是当设备的存储不多时把tlog停止

查看529的prop.txt没有sys.tlog.persist.active属性
在530之后就开始出现[sys.tlog.persist.active]: [1]
on property:sys.tlog.persist.active=0
stop tlogdPersist
setprop sys.tlog.persist.active 1

■目前进展
tlog -m进程crash信息在tombstone_07文件中，这个文件时是在000145次开机的时候产生的

而问题发生的时候是148次开机，tlog停的原因是因为设备存储不多主动把tlog停了的

■目前进展
E DTC_Display: screen not ready(0), bl_sta(119), lvl(0)的日志第一次打印是在第523的压缩包中，所以出现黑屏时的日志是有的，因为异常电压导致的黑屏

./FSEM_000148_0523_0518162550/kernel/000148_kernel_00331_700101_080009.log:1504:01-01 08:02:16.370     0     0 E DTC_Display: Abnormal voltage: 0mV

而tlog因为存储不多主动停止是在529，想要恢复也只有重启设备，所以后面的压缩包中的日志一直是重复的
■下一步计划

  • Status changed from RESOLVED to VERIFIED

客户BUG已关闭，反馈信息如下：
1、现场分析两个测试台架公用一个电源，当电流达到峰值后屏幕出现了黑屏，原因是电流不足背光无法打开，后续两个台架分开使用不同电源连续两天测试未复现出黑屏问题。
2、自5月22日后此台架独立使用一格电源情况下，monkey测试超过10天未出现黑屏现象，关闭此问题。
