We made the hardware backplane ourselves, and then ran our own program, but the system crashed inexplicably (if the system didn’t restart, the program process was abnormal). We passed the supervisor daemon, but the supervisor couldn’t check the process status. I checked the system log, but I didn’t finally determine which record caused the exception. Can you help me? kern.log (777.2 KB) syslog (1001.3 KB)
目标检测和目标跟踪,同时上面运行了java以及mysql,使用了串口
Target detection and target tracking. At the same time, Java and MySQL are running on it, and the serial port is used
我觉得和我的程序关系不大,应该是系统层面的问题,如果我们新作的硬件,是否需要重新编译内核呢,内核这块我不太懂,没有做额外的扩展,板子只是引出了一个HDMI,2个USB,两个串口,一个调试串口等
I don’t think it has much to do with my program. It should be a system level problem. If we make new hardware, do we need to recompile the kernel? I don’t know much about the kernel. I didn’t make additional enrollment expansion. The board just leads to one HDMI, two USB, two serial ports, one debugging serial port, etc
同样,我还测试了把固态放到套件的板子上就没有崩溃
Similarly, I also tested that putting the solid state on the board of the kit did not crash
情况大致就是这样,您能给我点建议如何排查这个问题么,系统日志有点看不明白和哪条记录有关系
The situation is basically like this. Can you give me some suggestions on how to troubleshoot this problem? The system log is a little unclear about which record it has to do with
OK, I know how to operate like this. Today’s test is based on this observation. There is no crash. At the same time, I would like to ask if the mode 20W CPU utilization rate is 100% sometimes. Will this lead to system instability
