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
