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:
