Output of OpenOCD

Till now I debuged my hardware (STM32F429) without using special RTOS support.
Then I followed the guide on
https://mcuoneclipse.com/2016/04/09/freertos-thread-debugging-with-eclipse-and-openocd/
to enable RTOS debug support. Unfortunately when trying to start debug gdb
exits with the following output (output of OpenOCD is attached):
