arm-usb-ocd-h swd stm32 reset problem

Hi
  I two setups. One of a arm-usb-ocd-h with a stm32-H103 and open-OCD. This works great with it.

  But the second with the same software setup, arm-usb-ocd-h, SWD and a OLIMEXINO-STM32 board only works if I press the board's reset during the open-ocd setup. So a couple of questions. 

1. What is the correct value for reset_config for the OLIMEXINO-STM32 board?

2. I thought is was working fine last week. I is it possible I blew out the reset driver pin of arm-usb-ocd-h? ie put the swd connector in back wards.

3. Is there a recommend open-ocd config for the OLIMEXINO-STM32 board?
 
Thanks and regards
-Jerry
