Jlink无法连接RT1064

colinluan · ‎10-23-2020

我在用在MCUXpresso环境下使用Jlink调试RT1064的时候提示如下错误：

确认过Jlink是好的，并且J-Link commander里可以识别RT1064. 之前是可以调试的，不知道为什么突然就出现了这样的问题，Jlink连接时的信息如下：

可以帮忙分析一下吗，非常感谢！

Hi，
你可以尝试设置启动模式为 Serial Download，然后进行debug, 等烧录完成后，恢复原先的启动模式再debug，看看是否还有问题。

Hi,
非常感谢使用NXP产品，很高兴为你提供技术支持！
从截图上看，好像已经进入debug，但是在debug过程中出现了错误，所以我想了解一下这个错误是在调试其他工程的时候有复现吗，在之前的调试中有出现过吗？

你好，之前一直都可以正常调试的，突然间就变成这样了，在此之前一直在尝试调整OCRAM，这个应该没有关系吧？而且一旦出现这种情况后Jlink就无法再次连接，必须重新上电后才能复现。Jlink在另一块ST的板子上确认是可以用的。

jeremyzhou · ‎10-25-2020

Hi,
就是说这个问题时最近才出现，而且只在debug i.MX RT1064中出现，那么debug SDK library 中的hello_world, LED等简单例程时有复现问题吗？还是只在debug 特定工程才会出现呢？我觉得你最后回忆一下你做了哪些操作后才出现的问题。

Hi,

所有的工程都会出现一样的情况，现在都卡在这边了，只有这么一块板子。我现在这边还有一个杂牌CMSIS-DAP，好像MCUXpresso也支持DAP协议，但是好像没法识别，这个需要特别的配置吗？

对了，忘了说一点，在现在的模式下Jlink可以识别芯片但是无法执行Erase操作

colinluan · ‎10-25-2020

进入Serial Download后用官方的工具来烧录吗？

jeremyzhou · ‎10-26-2020

Hi，
1) 进入Serial Download后用官方的工具来烧录吗？
-- 不是，直接点击MCUXPresso IDE中debug按钮下载就好了，程序其实也是可以下进去的，就是不能debug.

在Serial Download模式下使用Jlink可以在J-Link commander下擦除代码，但是按debug后会显示如下：

这个是正常现象吗？有没有办法在 Download模式下运行代码？我尝试在NXP-MCUBootUtility.exe里下载代码并且Start,好像并没有什么反应？

jeremyzhou · ‎10-26-2020

Hi，
正如你在回复中，按debug后会显示如下：

这是正确，然后紧跟着退出debug模式，恢复原先的boot mode设置后，再进行debug看看是否还会出现原来的问题。

非常感谢Jeremy的帮忙，我已经解决了问题，恢复到internal mode后，已经可以正常的调试了。

colinluan · ‎10-26-2020

这个我等会恢复一下看看，对了，顺便问一下，MCUXpresso里面的cmsis-dap只支持特定的设备吗？我看了官方的文档，似乎有支持其它的CMSIS-DAP设备？可以推荐一款通用型的DAP设备吗？我买了一个野火的DAP设备，IAR下可以用，但是MCUXPresso中无法识别。
