Hi. I use;

-STM32F4-DISCOVERY BOARD (with Embedded ST-Link V2)

-Win7 OS

-Eclipse Oxygen IDE

-OpenOCD debugger

I did every configuration about debugging on eclipse with OpenOCD. When I start debugging I get an error; **“undefined debug reason 7 - target needs reset”**

and **“Info : dropped ‘gdb’ connection”**

Any idea?
