I have bodged an Exar UART onto a DSTINIs400 board & need to use INT0 with it. As a starting point pressing a push button to create an INT to test a handler gets executed would be nice before getting into writing various UART routines. When I compile my C code, I get the warning L30: memory space overlap from c:200003H to c:200007H I'm not sure why this has happened & how do I get it working?? I am using the mon390 code to debug. Help! Thanks Trevor
The code I have written doesn't contain anything else That may be the case --- but that doesn't say anything about code others have already written, and which has become part of your project one way or another. That's why it's so important to actually go and check the full linker report, i.e. the map file.
OK - discovered map file... The startup400.a51 file I am using has
?C_CPURESET?0 segment code at 200000H
