How to configure HyperBus (in IOC) when external RAM signals are connected to OCTOSPI1 and also OCTOSPI2 (because of PCB layout) on STM32H725

[PZema.1]

Hi,

we have configured OCTOSPI1/2 follows :

 

But signal ChipSelect is not changing when we measure it. When we moved Chipselect to OCTOSPI2 ChipSelect is working ... How do we have to change configuration to work with ChipSelect on OCTOSPI1 ?

Thanks
