J3板子上运行高负载测试，cpu-stress.log程序报错

在J3板子上运行高负载的程序（地平线的xj3_ddr_stress）会导致芯片重启动。运行了DDR的压力测试，CPU测试有两种错误：

1、 偶尔出现：Report Error: miscompare : DIMM Unknown : 1 : 9428s

Hardware Error: miscompare on CPU 1(0xF) at 0x7fb0e84ee8(0x67da6ee8:DIMM Unknown): read:0xaaaaaaaa55555551, reread:0xaaaaaaaa55555551 expected:0xaaaaaaaa55555555

2、周期性出现(大概10min出现一次)： Log: Pausing worker threads in preparation for power spike (34200 seconds remaining)

2022/09/21-15:35:27(UTC) Log: Seconds remaining: 34190

Log: Resuming worker threads to cause a power spike (34185 seconds remaining)

    您好，从现象1来数据线DQ2的值出现了一次翻转，大概是出现了稳定性问题，从现象2看可能是芯片供电不稳定导致的，可以首先检查所选的供电电源是否符合要求。

      那请问在J3 DVB板上使用配的适配器跑的结果就是有周期性的打印，并且最后是pass的结果，这个算不算有问题

      您好，只要最后结果输出有下述pass的log就是ok的：
