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 STM32F746 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 |
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.
Limitations
External Debugger
The STM32F746 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:
