Hi,
I have a working old code in rom 32k, I added ram code at the upper 32k and I set the hw to start form the new ram at 32k.
I want to address old function from the new ram code without modify the old project.
once I compile the project code the hex output is not the old rom hex with the new ram code.
rather it recompiled the old code to optize it and I have a new hex that is not like the old rom hex with the new additions.
The thinng is that I need to address the old code function (fixed hex in rom).
what can I do?
regards, dan
if "the old code" as it does not "as is" call anything outside the ROM it is impossible to do what you want without modifying "the old code"
so SPECIFIC questions requiring SPECIFIC answers
a) does "the old code" call anything outside the ROM if no, then b) can you modify "the old code"
