Thank your for your help but my settings for OpenOCD and the debug  
configuration are exactly what you've written here.
Here are the console outputs after starting OpenOCD:

  and the arm-none-eabi-gdb.exe:

	symbol-file C:\\ethernut-4.10\\nutapp\\events\\events.elf
	Ignoring packet error, continuing...
	warning: unrecognized item "timeout" in "qSupported" response
	Ignoring packet error, continuing...

	Ignoring packet error, continuing...
	load C:\\ethernut-4.10\\nutapp\\events\\events.elf
	You can't do that when your target is `None'
	set $pc=0x20000000
	No registers.
	tbreak main
	Cannot access memory at address 0x200002a4
	continue
	The program is not being run.

For me it seems that the arm-none-eabi-gdb.exe has problems to access  
the controller.
