Hi, 

Regarding our development board using STM32F745VG, we would like to add QUADSPI FLASH in next our PCB board. But some QUADSPI_BK1_IOx(PE2 and PA1) are already connected to Ethernet IC. And 

QUADSPI_BK2

_IOx PINs are not used our PCB board now. Therefore, we would like to use QUADSPI_BK2

_IOx PINs and these PINs will be connected to QUADSPI FLASH.

Is it possible to use PE2(ETH_MII_TXD3) and PA1(ETH_MII_RX_CLK) functions and QUADSPI FLASH using QUADSPI_BK2

_IOx PINs?

We worry about we cannot control QUADSPI_BK1_IOx and QUADSPI_BK2_IOx independently.

Aki.
