Did you manage to fix this? It seems I have same problem. Yesterday everything worked ok, but today I just did some minor changes in code, and only some of the prints are working WHEN DEBUGGING. If i start without debugging, prints seems to be working ok. edit. ok, it was problem with my code, something corrupted RAM.

Have you tried these Segger RTT files from SDK 11? Have you modified the SEGGER_RTT_Conf.h file in anyway?

Hi Martin, I have a question

Does RTT will stop as soon as my device enters sleep mode?

Thanks and Regards, Faizan

What SDK are you using? SDK 11 has included the RTT files and uses them in e.g. the hrs example. There are some pretty big differences in the files in the SDK and the ones linked to in the tutorial. Have you tried the files in the SDK?

The strange thing is that it works for a while and then stops.

When you say messages do you mean complete messages? More than just a few characters?
Have you debugged your code to make sure it is not your application that halts?
Are you using an example from an SDK? If so which example and which SDK?
Do you mind sharing your code?

I have never experienced this. SEGGER-RTT uses non-blocking mode per default. Are you sure it is not your application that stops?
