I am beginner.Can you help me with using XRAM memory in this microcontroler? Can you write mi easy and objective example how write to XRAM and read from XRAM in C language? Or existing any routine with any methods for this operate?Than you very much! Ales
The Compiler knows nothing about your target hardware - so it has no idea how much XRAM it has. Also, the Compiler sees only 1 source file at a time - so it doesn't know what else may or may not be consuming RAM. That's why the Compiler can't give you any warnings about things like whether or not your code will actually fit into your particular target.
The Linker is what actually assigns addresses to code & data items; so the linker can warn if you overflow your physical capacities - but only if you correctly tell it what those capacities are!
You tell the Linker what your target's capacities are via its command-line options - or via your Project Configuration, if you're using the GUI.
The tutorials cited earlier walk you through the process of configuring a project - have you done the tuorials yet?
