====IAR example project====
 
The example project contains a simple counter loop which is linked into the (Q)SPI flash memory region @ address 0x90000000. The project includes the JLinkDevices.xml file as well as the ST_STM32F446_Reference.elf. It runs out-of-the-box. Please note, that IAR EWARM must at least use the J-Link DLL version V6.01a, which supports the Open Flash Loader.

QSPI Flash Programming Support

Before continuing with this article, please read the generic article about QSPI flash programming support on STM32F7 devices (STM32F7 (Q)SPI support).

Quad-SPI Interface Pins

The ST STM32F746G Discovery uses the following port pins to interface the (Q)SPI flash.

Alternate function Port / Pin
QSPI_CLK PB2
QSPI_CS PB6
QSPI_D0 PD11
QSPI_D1 PD12
QSPI_D2 PE2
QSPI_D3 PD13

Limitations

External Debugger

The STM32F746G Discovery board does not come with an connector for external debug probes. We recommend to convert the on board ST-Link to a J-Link OB in order to be able to use this board with J-Link:
