LPC Link 2 Dual Debug Configurations

jschepler — Thu, 16 Nov 2017 15:12:06 GMT

Hello,

I am using MCUXpresso IDE v10.0.2 with a Kinetis K64F processor. I have ported over the KSDK 1.3.0 version with MQX as the OS. We will not be migrating to KSDK 2.X series since MQX is no longer free.

I use the MQX TAD views since they are critical for viewing os performance. The only way this works with the LPCLink2 is if I use it in "all-stop" mode. However, we also like the "non-stop" feature of the LPCLink2 which is being able to view variables each second without having to pause program execution.

I would like to create 2 debug configurations for the LPCLink2: 1 in Non-Stop Mode, and 1 in All-Stop Mode.

Here is my procedure for creating these configurations.

Remove all LPC Link 2 configurations from the project.
Click the "Blue Bug" icon to automatically search for probes.
From the "Probes Discovered" dialog, choose IDE Debug Mode --> All-Stop.
Click Ok.
The debug session starts and all is well.
Stop debugging and go to LPCLink2 debug configurations.
Right-click on the configuration created automatically and select "Duplicate"
On the duplicated configuration go to the Debugger Tab, Main, and check "Non-Stop Mode"
Click Apply.
Click Debug.
The debug session will start and break at main like usual. However, when I press play I no longer have the "Pause" option available, it is grayed out.
It does stop at breakpoints and I am able to step when it breaks, but I don't have the option to pause. Also, when I press the red "Terminate" button it does not actually disconnect from the target. In task manager arm-non-eabi-gdb.exe is still running. I have to restart MCUXpresso after killing the arm-none-eabi-gdb task to be able to debug again, or it says a session is already deployed.

Is there something else that needs to be changed when I copy over the configuration?

Once I have an LPCLink2 configuration and I press the blue debug icon it automatically launches the one I created instead of pulling up the probe discovery dialog.

Hi,

the NonStop mode needs the following commands in the GDB init section of your debugging configuration:

set non-stop on
set pagination off
set mi-async

Thank you. Debugging works as expected now.
