Problem: Can't download program (to TWR-K60D100M) with MCUXpresso-IDE

[jerrylian]

I just run MCUXpresso-SDK example programs on board TWR-K60D100M:

* When I compiled and debugged, it runs well as specified in documentation

* But when I stop debugging, the example program won't work anymore.

* Even if we unplug/replug the board, the example program still won't work.

So: how can we download the program PERMANENTLY to the board with MCUXpresso-IDE?

Thanks!

You might have noticed semihosted I/O requires its' own library. The semihosting mechanism requires interaction by the debugger to process a BKPT exception to display I/O in the console view. If the debugger is not connected, the BKPT exception is otherwise not handled. Here's more information:

What is Semihosting?

Thanks and regards,

Hi Jerry,

It seems that you have semihosting enabled, please take a look to this thread:

Hope it helps!

Hi, Carlos:

Yes, it works, Thanks a lot!

* But shouldn't it be disabled by default? I guess most new users don't know the trick.

By the way, do you know why my post doesn't show up under "Overview" tab (it only shows up under "Content" tab).

* Post showing up under "Overview" draws more attention, right?

Thanks!

Jerry

Hi Jerry,

Thanks for your proposal. I would like to suggest you create a feature request for this feature.

How to submit a new question for NXP Support 

Personally I think  it would be good to have a short description for "semihosting enabled" in the page. Thus users will not overlook it easily.

your question " why my post doesn't show up under "Overview" tab". Normally if a thread get a new update, it will be posted to the top item in the "Overview" tab automatically.

Have a great day,
Jennie Zhang
