Mythical "Golden Reset Pad"

The erase pad is available only on the first gen Netduinos - it is connected to the [AT91SAM7] microcontroller ERASE pin, which enables you to perform full flash memory erase. Netduino gen 2 [STM32F] microcontrollers do not have this feature, you have to erase the flash memory via software (DFU utility or using a programmer).

I have heard this referred to in a couple of posts that there is a gold pad that when connected to 3.3V will erase and reset the Netduino/STM32. I also heard that this was not for Netduino/Plus 2, only first gen?

Is there a hardware reset for the STM32 or was this for the other microcontrollers that were used in other board revisions?
