Hi community ,
I'm currently working on STM32H747I DISCO0 Board .The peripheral I'm using is QSPI, I'm able to read/write and also enter Xip mode in CM7 .
Problem:

1)QSPI does not work in CM4 .Need to access QSPI in CM4 and perform same operations as read/write and Xip mode .
2)Please specify the Steps to be taken to work on CM4 for QSPI.

Details:
CubeIDE :Version: 1.12.1
CubeMX :6.10.0

Thank you and regards

    When you enable the peripheral in CubeMX, assign it to a core.

    You can assign it to both cores, but only one of them will initialize it. After initialization, both cores can access it, but ensure they don't try to do so at the same time.
