Hello @HA2375-

Hello @HA2375- 

The easiest way to do that is to create a project using the STM32CubeMX V6.15.0 and selecting the STM32U575VIT6 as MCU for this project. After that, enable one of the available octo-spi interfaces (the one that you want to use) and set the mode to quad-spi. The GPIOd that you need will be set for this interface on the Graphic. You can use those Pins.

Ps: please don’t forget to select a best answer for your previous question.

Best Regards.

Hello @HA2375- 

Those are not the correct pins. Please try the method I’ve mentioned before. It should be the easiest way.

Best Regards.
