Hello all,
I'm working with an STM Nucleo STM32F722 board for debugging with Eclipse
and Windows. This board is just available since a few days. I got the
following output:

Error: Connect failed. Consider setting up a gdb-attach event for the target
to prepare target for GDB connect, or use 'gdb_memory_map disable'.

I have added the following to src/flash/nor/ stm32f2x.c file.

This changes make OpenOCD work and below you can see the related output. I
compiled with MSYS2 on windows.
