FreeRTOS kernel aware debugging on NiosII

Hello,

I am looking for a FreeRTOS kernel aware debugging plugin for the Eclipse IDE which comes with Quartus 18.0

What I have tried so far:

I installed the Wittenstein Stateviewer plugin from http://stateviewer.highintegritysystems.com via Help / Install New Software. After restarting Eclipse, it crashes with an error message even before I can select the workspace:

An error has occurred. See the log file C:\......

=========

I had to delete the whole directory c:\users\***\.altera.sbt4e\18.0.0.614-windows64 to make Eclipse start again. The same error also occurred after the installation of some other plugins. It seems that Eclipse always crashes after the installation of any plugin. So I downloaded a standard (Non Quartus) Mars Eclipse for C/C++ and installed the Wittenstein Stateviewer plugin in it. I copied everything from the standard Eclipse installation directory into the Nios2 Eclipse (probably not the proper way) and was able to start a debug session and show the Wittenstein Stateviewer views, but all 3 views (tasks, queues, timers) are empty. The nios2-elf-gdb console view in Eclipse does not show any communication when I open one of the debug views, even when switched to verbose. I don't know wheter this is due to the improper installation or the plugin is just not compatible with NiosII or nios2-elf-gdb.

Configuration:

Quartus 18.0

Windows 10

FreeRTOS version 10.1.1

So, my two questions are:

- Is there a plugin for FreeRTOS kernel aware debugging on NiosII ?

- How to install a plugin in NiosII Eclipse IDE?

Regards,

Ramon
