各位好,我们使用RM44L520,我想问下我的程序中使用RTI定时器。但是现在我只要开启定时器中断,rtiEnableNotification(rtiNOTIFICATION_COMPARE1);
rtiStartCounter(rtiCOUNTER_BLOCK1);芯片自带的nerror引脚就会输出错误,这是什么原因。

但是nerror引脚有输出。
是输出低电平? An uncorrectable error will unconditionally cause the nERROR pin to toggle low.
应该是您的ECC不正确导致的
您可以看一下之前的讨论贴。这个板子有点老,我手边没有该板子为您实际测试
