Hi,

I wanted to know fit here is a way to tell the compiler to not to use a section of memory in the microcontroller.

Say for example I wanted to build a dynamically growing software stack, so i mark off 10k of memory which i can have a pointer to the base address and a pointer to the top of the stack.

How can i tell the compiler not to put any variables in that space, either marking it as do not use or fooling the compiler into thinking it doesnt exist.

Thanks,
Julian

You can modify the linker scripts.
