Running the IAP driver AN3965
6/13 Doc ID 022104 Rev 1
3 Running the IAP driver
3.1 HyperTerminal configuration
To use the IAP, the user must have a PC running HyperTerminal or other Terminal program
that supports ymodem protocol. In this document the HyperTerminal is used. Figure 2
shows the HyperTerminal configuration.
Figure 2. COM port properties
Note: The baud rate value of 115200 bps is used as an example.
Care must be taken when selecting the system clock frequency. To guarantee successful
communication via the USART, the system clock frequency in the end application must be
such that a baud rate equal to 115200 bps can be generated.
3.2 Executing the IAP driver
As an example, in this application note, pressing the push-button connected to the pin
launches the IAP driver.
By pressing the push-button at reset, the user can run the IAP driver to reprogram the
STM32F4xx internal Flash memory. It is not mandatory to use the push-button; the user can
apply a signal to this pin with respect to its active level. Refer to Table 1: STM32F4xx IAP
implementation.
