FreeRTOS kernel aware debugging on NiosII

The problem with the plugin installation was that an incomplete configuration file was created in the user directory during the installation of the plugins. I assume that this file overrides the default configuration file. I copied the directory C:/intelFPGA/18.0/nios2eds/bin/eclipse_nios2/configuration/org.eclipse.equinox.simpleconfigurator to

C:/Users/***/.altera.sbt4e/18.0.0.614-windows64/configuration. After that, I was able to install plugins.

I also made some progress with the Wittenstein plugin. Some data it displays still seem to be incorrect, probably because my FreeRTOS is not correctly configured for kernel aware debugging yet. But at least I can get some output.

The problem here was that the "Nios II Hardware" debug session is not recogniced by the Wittenstein plugin. I had to use a standard "GDB Hardware Debugging" configuration.

Installation:

• In Eclipse, go to Help / Install New Software
• Work with: http://download.eclipse.org/releases/mars/
• Select "C/C++ GDB Hardware Debugging"

Debugging:

• Open a Nios II Command Shell
• Download the firmware and start GDB server:

nios2-download project.elf
nios2-gdb-server --tcpport 12345 --tcppersist

• Create and start a debug configuration under the newly installed GDB Hardware Debugging category
