The delay time measured in milliseconds. delay is ignored and should be 0.

strategy

The reset strategy:

0, (System) performs the standard reset procedure. Only available for debugging Cortex-M devices.

1, (Hardware) uses the reset pin to perform a hardware reset. Only available for ST-LINK version 2.

2, (Connect during reset) ST-LINK connects to the target while keeping Reset active (Reset is pulled low and remains low while connecting to the target). Only available for ST-LINK version 2 and when debugging Cortex-M devices.

3, (Core) resets the core via the VECTRESET (Cortex-M) or CWRR (Cortex-A) bit—the peripheral units are not affected.

4, (Software) Sets the PC to program entry address and SP to the initial stack pointer value.
