Setting up a variable at a fixed location

[Daniel]

Hi,

I want to reserve a space of two bytes in flash so I can change those externally. I want to read same memory location from the code.

How do I do it? 

How to read a variable from a specific memory address and how to change linker or any other file to write a specific value to that address.

Hi Daniel

I'm sorry, but I don't think I know exactly what you mean here. I'm not aware of anything like this. Can you try explaining a bit more in detail what you'd like to achieve?

Best regards,

Simon
