STM32F107 IWDG does not make a reset

Hello,

I'm using the ST libraries to initialize the IWDG  with following code:
 IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable);
  IWDG_SetPrescaler(IWDG_Prescaler_128);
  IWDG_SetReload(0x400);
  IWDG_ReloadCounter();
  IWDG_Enable();

after 3 seconds the watchdog should make an reset, but the reset fails (no watchdog timeout).

I have tested the code on an other board (different hardware) with the same cpu,  and on this hardware the IWDG reset is working

does anyone have any idea ?

 Thanks,

Harald
