ChibiOS Free Embedded RTOS

i saw the iwdg source in chibios 172 ,and i try to use it .but it doesn't work . the register can be set to right value. but it doesn't reset stm32(i'm not reset iwdg).and the register value is ffff .
who can give me some advice to deal this problem ?
maybe i need try to use wwdg and write wwdg driver ?
thanks.

Hi,

I have not tested it on F1, look at the demos for F0, F3 etc, the driver is very simple in itself.
