You may have a config file error.

I use the following in my config file, which works for me with the OpenOCD in the YAGARTO distribution.

It appears that you are trying to use “B” instead of “A” in your config file.

Thanks for help

Ok I got working debugger but when i do step over

i got warning

so what can be do to remove this warning?

Info: openocd.c:82 main(): Open On-Chip Debugger (2006-10-12 18:00 CEST)

Warning: arm7_9_common.c:842 arm7_9_halt(): target was already halted

Info: server.c:67 add_connection(): accepted ‘gdb’ connection from 0

Warning: arm7_9_common.c:1798 arm7_9_read_memory(): memory read caused data abort (address: 0xfffffffe, size: 0x1, count: 0x4)

Presumably the GDB requested that read when it was trying to trace the stack frames. This Warning usually isn’t critical.
