    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！

    版本信息：

    ti-processor-sdk-linux-rt-am57xx-evm-04.03.00.05
    ti-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。

    是否在IPU1中使用定时器需要指定“timer11”，也就是需改代码如下：

    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。
