问题描述：在linux端加载编译好的固件就一直打印以下问题，能帮忙分析一下是什么问题导致的吗？谢谢！
定时器配置：
Timer_Params timerParams;Timer_Handle myTimer;Timer_Params_init(&timerParams);timerParams.arg = 1;timerParams.period = 1000000;timerParams.periodType = Timer_PeriodType_MICROSECS;timerParams.runMode = Timer_RunMode_CONTINUOUS;timerParams.startMode = Timer_StartMode_USER;myTimer = Timer_create(Timer_ANY, &timer_isr_function, &timerParams, NULL);if (myTimer == NULL) {System_abort("Timer create failed");} else {Timer_start( myTimer );}
问题打印：

Nancy Wang：
请贴出SDK版本，另外您是在添加了TIMER配置代码之后才出现问题的吗？是在DSP端添加的吗？请再详细描述一下,谢谢！

ti-processor-sdk-linux-rt-am57xx-evm-04.03.00.05ti-processor-sdk-rtos-am57xx-evm-04.03.00.05
问题是在添加TIMER代码后出现的，是在IPU1上添加的。我这边使用的是“ti-linux-ipc-examples\ex02_messageq\src\ipu1”的例程进行修改的。例程可以正常使用。

感谢提供信息，我会在咨询相关工程师后给您回复。

&ipu1 {status = "okay";memory-region = <&ipu1_cma_pool>;mboxes = <&mailbox5 &mbox_ipu1_ipc3x>;timers = <&timer11>;watchdog-timers = <&timer7>, <&timer8>; };是否在IPU1中使用定时器需要指定“timer11”，也就是需改代码如下：
Timer_Params_init(&timerParams);timerParams.arg = 1;timerParams.period = 1000000;timerParams.periodType = Timer_PeriodType_MICROSECS;timerParams.runMode = Timer_RunMode_CONTINUOUS; //timerParams.startMode =Timer_StartMode_USER; //myTimer = Timer_create(Timer_ANY, &timer_isr_function, &timerParams, NULL);myTimer = Timer_create(10, &timer_isr_function, &timerParams, NULL);if (myTimer == NULL) {System_abort("Timer create failed");} else {Timer_start( myTimer );}谢谢！

Cherry Zhou：
您好我们已将您的问题升级到英文论坛，预计将在24小时内回复您。谢谢！

zStoneTh：
报错问题解决了，预计是未先初始化定时器时钟，就开始操作定时器了。但是目前发现定时器无法正常工作，正在继续查找原因。
