CubeIDE - How can I Debug Step into functions located in ITCM?

[David George]

I have a STM32H730 Project, using CubeIDE V1.17.0. Code executing from the internal Flash.

I have located some functions into ITCM,

• added a new .itcram section to the linker LD file
• added __attribute__((section(".itcram"))) to my functions I want in ITCM
• at startup I copy from FLASH to ITCM 

This builds and runs okay, the functions in ITCM execute as expected.

But, I can't Debug Step into any function located in ITCM, it just steps over the function.

I can set a breakpoint in a ITCM function, but it never halts there, just ignores the breakpoint.

 

How can I step into functions located in ITCM?

Do I need to tell GDB that I have instruction code in ITCM?

 

Thanks.
