Bug: FreeRTOS task viewer crashes

[davenadler]

Trying to use the FreeRTOS task viewer shows the following error for ~one second and then KDS switches to a different tab:

The TAD log shows:

The FreeRTOSviewer worked a few days ago on this project (no obviously relevant changes since it was working).

Anybody seen this bug? Work-around?
Thanks in advance,
Best Regards, Dave

PS: FreeRTOSConfig.h is attached...

OpenOCD window seems to show reading a bad pointer?

Here's the FreeRTOS plugin installation detail:

Another slightly different crash:

Footnote: I switched to a Segger JLink debugger as the Freescale/NXP-supplied OpenOCD/SDA combo was too buggy and slow for production work (JLink is enormously faster: loads and starting debug have gone from many seconds to virtually instantaneous). The FreeRTOS viewer works fine with the Segger JLink.

So, the bug is would appear to be (yet another) problem with the OpenOCD/SDA combo.

Hello Dave,

- Maybe you have not download the project into chip correctly .

Please first delete the ".metadata" folder under KDS workspace, then re-open

the KDS, build project , download it into chip again , run it to have a try .

- If it still can not work . please try another project to check whether the Task List can work well .

Hope it helps
Have a great day,
Alice Yang

What exactly is that supposed to mean? The code downloads and runs fine and the FreeRTOS queue viewer works. All tasks have adequate stack space (checked the hard way since the task viewer crashes). Only problem is I can't check the task statistics with the FreeRTOS task viewer.

Exact same result: I deleted .metadata and re-imported project as you suggested - FreeRTOS viewer still crashes.
I have attached the log file from Eclipse.

Yes the FreeRTOS Task viewer works on some projects, but I do not see any obvious difference between the projects.

Absolutely no help. It would be a better day if these tools would actually work...

I will separately attach the log file from Eclipse.

It would be great if you can pass this information to someone able to diagnose the problem,

Thanks,
