ALT_EXCEPTION_STACK macro does not create exception_stack memory region

Hi!

I'm using Quartus Standard Prime 23.1.1 to upgrade a NiosII C10LP design to NiosV and I'm having trouble with the BSP / Linker.

From the description of the hal.linker.enable_exception_stack option in settings.bsp:

Enables use of a separate exception stack. If true, defines the macro ALT_EXCEPTION_STACK in linker.h, adds a memory region called exception_stack to linker.x, and provides the symbols __alt_exception_stack_pointer and __alt_exception_stack_limit in linker.x.

So, in my linker.h file I do see the macro ALT_EXCEPTION_STACK defined; however, in my linker.x there is no memory region called exception_stack.

Is there something else I need to do to make sure this memory region is generated?

    Hi

    Apologies for the delay in getting back as was tied up with issue backlog, may I know whether the issue been resolved on your end?

    For the linker exception , I saw there is some restriction mentioned at NiosV guide

    https://www.intel.com/content/www/us/en/docs/programmable/743810/22-4-22-4-0/bsp-settings-reference.html

    Just make sure to adhere to the restriction condition mentioned in the link above. Is there an issue or error that you're facing when migrating to Nios V design?

    Thanks

    Regards
