MCUXpresso not killing redlinkserv.exe after terminating debug session on LPC4078

I've recently upgraded from LPCXpresso to MCUXpresso. LPCXpresso is still installed on the machine that I'm havnig problems with.

I'm trying to run/debug a project targeting a custom LPC4078 board. I can debug the project fine, but when I right click on the debug session and choose either "Terminate" or "Terminate and Relaunch", MCUXpresso doesn't kill redlinkserv.exe and so when I next go to debug the software (or it launches a new debug session automatically when I choose "Terminate and Relaunch", I get the error:

No debug targets available

All SWD targets are currently connected to other debug sessions.

However, by this point the debug session listed in the debug window is shown as terminated.

The solution is to kill redlinkserv.exe in the task manager. Obviously if you're debugging things frequently this is quite tedious.

I don't have this problem with an old version of LPCXpresso running on the same machine. I can repeatedly terminate and relaunch debug sessions without issue. LPCxpresso did have this issue rarely, but rarely enough that it didn't significantly impact debugging.

Is this a bug or a configuration issue on my machine? Does anyone else have this problem debugging LPC targets using MCUXpresso 10.1.0?

I'm running Windows 10

Quick and dirty workaround:

In order not to abandon the IDE I found a way to close the redlinkserver from inside it: 

1.- If the debug session is running look and click the icon "Terminate all debug sessions" (it's a two red squares at the right side of "pause" icon in the tool bar). Don't click on the "Terminate" icon.

2.- In the same tool bar look and click the icon "Clean up debug" (it's a red square with a cross in front of it, located at the right of something that remains a red boot). If the debug session wasn't running, then click twice this icon.

This secuence works for me in Linux Mint.

Any useful answer after two years? I do have the same problem, but in a Linux box, running MCUXpresso IDE v11.0.0, Build 2516, debugging a LPCXpresso LPC11U68 board.

Instead of killing the server by hand, I need to launch the debug session twice, and then it works. It's kind of annoying.

Although there are some slight differences between redlink in LPCXpresso IDE and MCUXpresso IDE, I would not expect you to see different behaviour of the type you describe. Basically in both toolchains RedlinkServer should normally terminate once all debug sessions connecting through it terminate.

Please can you:

1) Ensure that all debug sessions have been terminated within the IDE.

2) Make sure that there are no debug related services still running, so check in Task Manager (or similar) and kill anything of the form:

  • redlinkserv
  • arm-none-eabi_gdb*
  • crt_emu_*

3) Check in the "IDE Preferences -> MCUXpresso IDE -> LinkServer Options" and make sure that these two options are ticked:

  • Shutdown redlink server
  • Kill redlink server on exit

Now start a debug session. Does it connect?

Assuming it does, now click on Terminate.

Wait a few seconds then check in Task Manager - have all debug related services now terminated?

If not, please provide to us the Contents of both the Debug log (Debug Messages) and the Redlink Server log from the Console view (as per section 16.8, "The Console View", of the MCUXpresso IDE v10.1 User Guide).

Can you also confirm what debug probe you are using?

PS : One thing to watch would be to make sure you don't try and have the version from LPCXpresso and MCUXpresso running at the same time. ie make sure that you are allowing MCUXpresso IDE to run the version it ships with, not having the old LPCXpresso IDE one left running.

Regards,

If I debug by terminating 

When I terminate via right click -> terminate on the session, the Console shows the following:

After terminating the session through this method, redlinkserv.exe is still runnning. (Only redlinkserv is)

If I kill redlinkserv.exe through the task manager and then re-launch the debug session, and then kill it again by clicking the "Terminate All" button, I get the following:

The debugger is LPC-Link 2. I've tried with 2 different debuggers and a number of boards (all of the same design) with the same result.

I've followed the steps you suggested. The 2 linkserver options were selected already.

I'm having the same problem - right clicking on the debug session and choosing "Terminate" or "Terminate and Relaunch" fails to kill redlinkserv

However, I did discover that clicking the "Terminate All" button at the top of the window after starting a debug session does kill redlinkserv. It seems that the problem is specifically in terminating a specific debug session rather than terminating all of them.
