H743 ._user_heap_stack in D2 section causes Hard Fault

Hello.

Why is it not possible to point the ._user_heap_section in the D2 RAM section?

A tiny project based on SW4STM32 for NUCLEO-H743ZI is attached.

I just modified the linker script to have _user_heap_stack in D2 and not DTCM or D1.

I'm not able to debug this app.

Basically there is a D1-to-D2 AHB bridge to provide a link via AXIM to the CPU.

I have no idea because it works when it is located in D1 for instance.

Thank you, Joerg
