Other Parts Discussed in Thread: THS8200
芯片：TI DM8168
SDK版本：DVRRDK_04.00.00.03
kernel版本：Linux version 2.6.37+
我们的产品：视频会议终端
硬件设计简介：
1、我们采用的是一个DM8168芯片
问题描述：
1、我们在开视频会议时，随机碰到某个终端死机（DM8168的串口无响应、IP不通；同时，DM8168对应的第一个视频输出黑屏）。
使用场景：4M带宽，H.264HP，1080P30的视频编解码，AAC-LC的编解码
出现概率：半天~1周左右，时间不定，没有什么规律
初步定位：
1、抓到一次出问题的串口日志：
1）开机时间：2023.12.26 09:39左右
2）DM8168挂掉时间：2023.12.26 13:28:59
----本次跑了4小时左右挂掉，挂掉之前串口有一些报错
串口日志：2023-12-26-094214-serial-com6_____172.16.40.151.log(详细看上传的附件)
述求：
请帮我们看看DM8168死机问题，可以借助串口日志看看，贵公司是否有碰到类似问题，请给出解决方法
串口日志从2023.12.26 10:17:09的部分截取如下所示。(详细看附件)
