I’m be interested to use OpenSTM32, as it runs across platforms of Linux,MacOSX and Windows, 
with Eclipse and plugins to integrate Gnu ARM GCC and OpenOCD.
But I get a problem when try to start debugging session on the board of STM32F0308-Discovery. I have the all toolchain installed and updated to latest. Start debugging on STM32F0Discovery
board is all fine.
The failure message on  STM32F0308-Discovery says timeout and failed on holding reset,
and further information seems prompt a failure on erasing flash.  I tried to invoke Target=> Erase chip,
from OpenSTM32, and it failed on timeout.  However, when I try to use “ST-Link Utility” to
erase and programing the board of STM32F0308-Discovery, it went through all fine. And also,
I have another set of wrapper tool over OpenOCD, can start debugging session properly,
which of course means of erase/programming the flash on  STM32F0308-Discovery properly.
So, after all, I have the question to the configuration file on OpenOCD for 
STM32F0308-Discovery and STM32F0Discovery.  I know they are been provided differently,
the question is, what the essential difference need to be between the two of OpenOCD configure
file? Please help.
