Hello @APras.2​,

With the STM32G473 you can use the QuadSPI interface in the memory mapped mode in order to:

• To use external Quad-SPI Flash memory like an internal memory, so any AHB master can read data

autonomously.

• For code execution from external Quad-SPI Flash memory.

I recommend you referring to the AN4760 for more details.

Thank you.

Yes, you should be able to memory map the QUADSPI device, have it present on the I and D-Bus

Should support devices up to 256MB (2Gb)
