FreeMaster using PE micro debugger

Stark_ — Thu, 03 Apr 2025 07:41:01 GMT

As mentioned FreeMASTER support real-time debug monitor and data visualization tool that enables runtime configuration and tuning of embedded software applications.

I tried to connect NXP microcontroller and FreeMaster through PE micro multi universal debugger for monitoring the variable at run time. But i cant make it proper.

Is is possible to use FreeMASTER using PE micro multi universal debugger for monitoring data?

Hello,

from your screenshot it seems like a problem in FreeMASTER installation. The communication plug-ins are probably not installed properly. You can confirm this by going to Project/Options - the drop-down list of Plug-in modules will probably be empty in your case:

How to fix the installation:

Close FreeMASTER
Open file explorer in "c:\NXP\FreeMASTER 3.2\FreeMASTER" directory
Locate the "register.bat" file
Right-click the file and select "Run as administrator"
Start FreeMASTER, the plug-ins shall now be visible in Project/Options dialog.

Regards,
Michal

Hi @MichalH

Thanks for the quick response.

As you said " Project/Options - the drop-down list of Plug-in modules will probably be empty in your case " was correct and followed the step you mention, after that can able to see the plugin in FreeMASTER. when i try to run with the mention setting (i.e, FreeMaster P&Emicro communication plugin (Cortex-M, power pc, HCS08/12, Cold fire) ). but again got an error message.

Is is possible to use FreeMASTER with P&Emicro debugger? for that any lib should be added in project file ?

The error you show now in the screenshot is reported by the P&E Micro debugging function already - it seems the P&E probe cannot connect to the target MCU.

What is your target MCU?
What is the type of P&E probe?
Can you use a CodeWarrior or other debugger with the P&E probe?

Thanks,
Michal

Hi @MichalH

once I flash my microcontroller after that i just connect with FreeMASTER. but it show an error

MCU is used is S32K3 series

P&E micro Multilink universal FX

IDE used S32 Design studio

There are two important points:

The S32 Design Studio (debugger) must be disconnected from the target when attaching FreeMASTER. The P&E probes cannot handle simultaneous connection from two client applications.
The FreeMASTER plug-in shall know what MCU part number you are using. Go to Project/Options, open the configuration dialog and select the MCU type like in the picture below:

OK, so the connection problem is resolved.

For general use of FreeMASTER, please refer to User Guide. In short: you have used the ELF file to load symbols; now you need to create so called FreeMASTER Variables, where you select a symbol/address, size, reading period, format, etc. to be displayed in FreeMASTER. Once you have the FreeMASTER variables defined, you can observe them in a grid or in graphs.

Please close this thread as the initial issue has been resolved. If you have any questions on general FreeMASTER usage after reading the User Guide, please start a new thread on this forum.

Michal
