海思
 
3531官方板卡，运行venc 出现系统崩溃 日志显示为cpu负载均衡出现问题，但没有发现哪涉及到这个东东，再说负载均衡不是linux自行管理吗？程序如何会导致系统崩溃？

该问题出现的情况还不能确定，有时候连续运行12小时没有问题，有时候几分钟一次。

基本上,这种问题多数是驱动(尤其是自己写的)中出现了非法内存访问(比如数组越界)造成的

感谢回复，驱动只有tw2865基于官方修改的几个参数，其他都没有变化。venc程序大量修改了，但程序应该是不会造成这个情况吧？

这个只能倒过来推

海思sample还是很稳定的, 如果基于此改出来的程序出了问题,一般都是改的问题

可能是系统的时钟频率过高导致drr出现问题，你烧写一个时钟频率低的uboot试一下，看看可不可以正常引导内核。

如果保护的好，if(!para)reurn;
用的比较多，效率就低，但是稳定，尤其当线程繁杂，互锁机制繁杂，有些情况我们写程序的是想不到的，只能做被动保护，容错机制。

////////////////////////////我一般编程习惯就是牺牲效率，只要是指针，使用前，尽量看看是否合理。

//内存拷贝前，检查数据大小也很重要。一个sprintf(str,"%s",str2);都会出现你出现的情况，如果str[255],str2[256],平时不会有事，但如果系统快完蛋了，str2里面如果全是FF，就会尝试拷贝256个字符到str,问题就来了。就越界了，崩溃。
所以才有snprintf替代，拷贝时，直接使用大小参数。

/////////////////////////使用排除法，去掉某些模块测试，如果同样是高温，程序如果不挂，再来自己研究模块代码。


///你的下面的这个报错，很明显是内存指针问题了。Unable to handle kernel NULL pointer dereference at virtual address 00000003

//第一个报错Unable to handle kernel paging request at virtual address bb61b6ec/////////////bb61b6ec这个指针都跑哪去了 3G左右了。

//但引起这个问题的根，可能在其他层面，仅仅看这些log，很难定位。只能广撒网，找问题了。


/////////////////另外，6楼的说法也很有可能，如果DDR不稳定，CPU过热不稳定，数据乱很正常了。
