使用TRK-KEA8重新上电故障

[327140005]

您好，我想问下，我在使用nxp的TRK-KEA8这个板子的时候， 编译环境为CodeWarrior。 使用自带pe的生成代码功能生成了代码，实现了 简单的LED亮灭效果。 但是在我下电之后重新上电，LED并没有出现之前的亮灭情况，请问这是为什么呢？

楼主你好！

建议你看下这篇文章：

【经验分享】kinetis flash中仿真可以烧录运行失败问题讲解 - Kinetis - 恩智浦技术社区 - 手机版 - Powered by Discuz! 

如果你确实是下载到flash，那么应该和你的EWL库有关。

Wish it helps you!

If you still have questions about it, please kindly let me know.

Hi 尧 付 ,

   楼主你好！

   你那边检查下，你的代码是下载在RAM还是flash了？

   你可以看下左上角，编译的地方，还有你debug的时候，也可以看下汇编的地址，到底是RAM还是flash地址。

   如果是RAM 的话，那么你的结果是正确的，下载之后，重新上电数据就没了，只有你下载到flash，重新上电才能跑起来。

   希望能帮到你。

   如果还有问题，欢迎继续交流！

Wish it helps you!

我查看了一下，确认肯定是烧录到 flash当中，而不是 ram当中， 我是用官方给的例程，没有出现断电代码消失的情况。
