How to enable memory mapping of the Flexspi controller?

Hi,
I'm working with an i.MXRT1064 microcontroller and since I have to communicate with a QSPI Flash I'm using the FlexSPI controller.
I used as a starting point the example "flexspi_nor_polling_transfer" of the SDK and the i.MX RT1064 EVK board.
The example works correctly and when I write/erase the QSPI Flash I get confirmation from Keil's 'windows' tool as the memory mapped mode is active.

The problem is that I can't use memory mapped mode on a custom board that uses the same microcontroller.
If I send a GetInfo command to the QSPI Flash it replies correctly, but it is as if the memory mapped mode was not active.
Do I have to configure it somehow?
The code written mirrors the example of the SDK mentioned above.

Greetings,
Thomas
